Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator). | |||||
Extracted from [koa](https://www.npmjs.com/package/koa) for general use. | |||||
In addition to negotiator, it allows: | |||||
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])` | |||||
as well as `('text/html', 'application/json')`. | |||||
- Allows type shorthands such as `json`. | |||||
- Returns `false` when no types match | |||||
- Treats non-existent headers as `*` | |||||
## Installation | |||||
This is a [Node.js](https://nodejs.org/en/) module available through the | |||||
[npm registry](https://www.npmjs.com/). Installation is done using the | |||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): | |||||
```sh | |||||
$ npm install accepts | |||||
``` | |||||
## API | |||||
<!-- eslint-disable no-unused-vars --> | |||||
```js | |||||
var accepts = require('accepts') | |||||
``` | |||||
### accepts(req) | |||||
Create a new `Accepts` object for the given `req`. | |||||
#### .charset(charsets) | |||||
Return the first accepted charset. If nothing in `charsets` is accepted, | |||||
then `false` is returned. | |||||
#### .charsets() | |||||
Return the charsets that the request accepts, in the order of the client's | |||||
preference (most preferred first). | |||||
#### .encoding(encodings) | |||||
Return the first accepted encoding. If nothing in `encodings` is accepted, | |||||
then `false` is returned. | |||||
#### .encodings() | |||||
Return the encodings that the request accepts, in the order of the client's | |||||
preference (most preferred first). | |||||
#### .language(languages) | |||||
Return the first accepted language. If nothing in `languages` is accepted, | |||||
then `false` is returned. | |||||
#### .languages() | |||||
Return the languages that the request accepts, in the order of the client's | |||||
preference (most preferred first). | |||||
#### .type(types) | |||||
Return the first accepted type (and it is returned as the same text as what | |||||
appears in the `types` array). If nothing in `types` is accepted, then `false` | |||||
is returned. | |||||
The `types` array can contain full MIME types or file extensions. Any value | |||||
that is not a full MIME types is passed to `require('mime-types').lookup`. | |||||
#### .types() | |||||
Return the types that the request accepts, in the order of the client's | |||||
preference (most preferred first). | |||||
## Examples | |||||
### Simple type negotiation | |||||
This simple example shows how to use `accepts` to return a different typed | |||||
respond body based on what the client wants to accept. The server lists it's | |||||
preferences in order and will get back the best match between the client and | |||||
server. | |||||
```js | |||||
var accepts = require('accepts') | |||||
var http = require('http') | |||||
function app (req, res) { | |||||
var accept = accepts(req) | |||||
// the order of this list is significant; should be server preferred order | |||||
switch (accept.type(['json', 'html'])) { | |||||
case 'json': | |||||
res.setHeader('Content-Type', 'application/json') | |||||
res.write('{"hello":"world!"}') | |||||
break | |||||
case 'html': | |||||
res.setHeader('Content-Type', 'text/html') | |||||
res.write('<b>hello, world!</b>') | |||||
break | |||||
default: | |||||
// the fallback is text/plain, so no need to specify it above | |||||
res.setHeader('Content-Type', 'text/plain') | |||||
res.write('hello, world!') | |||||
break | |||||
} | |||||
res.end() | |||||
} | |||||
http.createServer(app).listen(3000) | |||||
``` | |||||
You can test this out with the cURL program: | |||||
```sh | |||||
curl -I -H'Accept: text/html' http://localhost:3000/ | |||||
``` | |||||

Node.js body parsing middleware. | |||||
Parse incoming request bodies in a middleware before your handlers, available | |||||
under the `req.body` property. | |||||
**Note** As `req.body`'s shape is based on user-controlled input, all | |||||
properties and values in this object are untrusted and should be validated | |||||
before trusting. For example, `req.body.foo.toString()` may fail in multiple | |||||
ways, for example the `foo` property may not be there or may not be a string, | |||||
and `toString` may not be a function and instead a string or other user input. | |||||
[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/). | |||||
_This does not handle multipart bodies_, due to their complex and typically | |||||
large nature. For multipart bodies, you may be interested in the following | |||||
modules: | |||||
* [busboy](https://www.npmjs.org/package/busboy#readme) and | |||||
[connect-busboy](https://www.npmjs.org/package/connect-busboy#readme) | |||||
* [multiparty](https://www.npmjs.org/package/multiparty#readme) and | |||||
[connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme) | |||||
* [formidable](https://www.npmjs.org/package/formidable#readme) | |||||
* [multer](https://www.npmjs.org/package/multer#readme) | |||||
This module provides the following parsers: | |||||
* [JSON body parser](#bodyparserjsonoptions) | |||||
* [Raw body parser](#bodyparserrawoptions) | |||||
* [Text body parser](#bodyparsertextoptions) | |||||
* [URL-encoded form body parser](#bodyparserurlencodedoptions) | |||||
Other body parsers you might be interested in: | |||||
- [body](https://www.npmjs.org/package/body#readme) | |||||
- [co-body](https://www.npmjs.org/package/co-body#readme) | |||||
## Installation | |||||
```sh | |||||
$ npm install body-parser | |||||
``` | |||||
## API | |||||
<!-- eslint-disable no-unused-vars --> | |||||
```js | |||||
var bodyParser = require('body-parser') | |||||
``` | |||||
The `bodyParser` object exposes various factories to create middlewares. All | |||||
middlewares will populate the `req.body` property with the parsed body when | |||||
the `Content-Type` request header matches the `type` option, or an empty | |||||
object (`{}`) if there was no body to parse, the `Content-Type` was not matched, | |||||
or an error occurred. | |||||
The various errors returned by this module are described in the | |||||
[errors section](#errors). | |||||
### bodyParser.json([options]) | |||||
Returns middleware that only parses `json` and only looks at requests where | |||||
the `Content-Type` header matches the `type` option. This parser accepts any | |||||
Unicode encoding of the body and supports automatic inflation of `gzip` and | |||||
`deflate` encodings. | |||||
A new `body` object containing the parsed data is populated on the `request` | |||||
object after the middleware (i.e. `req.body`). | |||||
#### Options | |||||
The `json` function takes an optional `options` object that may contain any of | |||||
the following keys: | |||||
##### inflate | |||||
When set to `true`, then deflated (compressed) bodies will be inflated; when | |||||
`false`, deflated bodies are rejected. Defaults to `true`. | |||||
##### limit | |||||
Controls the maximum request body size. If this is a number, then the value | |||||
specifies the number of bytes; if it is a string, the value is passed to the | |||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults | |||||
to `'100kb'`. | |||||
##### reviver | |||||
The `reviver` option is passed directly to `JSON.parse` as the second | |||||
argument. You can find more information on this argument | |||||
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). | |||||
##### strict | |||||
When set to `true`, will only accept arrays and objects; when `false` will | |||||
accept anything `JSON.parse` accepts. Defaults to `true`. | |||||
##### type | |||||
The `type` option is used to determine what media type the middleware will | |||||
parse. This option can be a string, array of strings, or a function. If not a | |||||
function, `type` option is passed directly to the | |||||
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can | |||||
be an extension name (like `json`), a mime type (like `application/json`), or | |||||
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` | |||||
option is called as `fn(req)` and the request is parsed if it returns a truthy | |||||
value. Defaults to `application/json`. | |||||
##### verify | |||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, | |||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the | |||||
encoding of the request. The parsing can be aborted by throwing an error. | |||||
### bodyParser.raw([options]) | |||||
Returns middleware that parses all bodies as a `Buffer` and only looks at | |||||
requests where the `Content-Type` header matches the `type` option. This | |||||
parser supports automatic inflation of `gzip` and `deflate` encodings. | |||||
A new `body` object containing the parsed data is populated on the `request` | |||||
object after the middleware (i.e. `req.body`). This will be a `Buffer` object | |||||
of the body. | |||||
#### Options | |||||
The `raw` function takes an optional `options` object that may contain any of | |||||
the following keys: | |||||
##### inflate | |||||
When set to `true`, then deflated (compressed) bodies will be inflated; when | |||||
`false`, deflated bodies are rejected. Defaults to `true`. | |||||
##### limit | |||||
Controls the maximum request body size. If this is a number, then the value | |||||
specifies the number of bytes; if it is a string, the value is passed to the | |||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults | |||||
to `'100kb'`. | |||||
##### type | |||||
The `type` option is used to determine what media type the middleware will | |||||
parse. This option can be a string, array of strings, or a function. | |||||
If not a function, `type` option is passed directly to the | |||||
[type-is](https://www.npmjs.org/package/type-is#readme) library and this | |||||
can be an extension name (like `bin`), a mime type (like | |||||
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or | |||||
`application/*`). If a function, the `type` option is called as `fn(req)` | |||||
and the request is parsed if it returns a truthy value. Defaults to | |||||
`application/octet-stream`. | |||||
##### verify | |||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, | |||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the | |||||
encoding of the request. The parsing can be aborted by throwing an error. | |||||
### bodyParser.text([options]) | |||||
Returns middleware that parses all bodies as a string and only looks at | |||||
requests where the `Content-Type` header matches the `type` option. This | |||||
parser supports automatic inflation of `gzip` and `deflate` encodings. | |||||
A new `body` string containing the parsed data is populated on the `request` | |||||
object after the middleware (i.e. `req.body`). This will be a string of the | |||||
body. | |||||
#### Options | |||||
The `text` function takes an optional `options` object that may contain any of | |||||
the following keys: | |||||
##### defaultCharset | |||||
Specify the default character set for the text content if the charset is not | |||||
specified in the `Content-Type` header of the request. Defaults to `utf-8`. | |||||
##### inflate | |||||
When set to `true`, then deflated (compressed) bodies will be inflated; when | |||||
`false`, deflated bodies are rejected. Defaults to `true`. | |||||
##### limit | |||||
Controls the maximum request body size. If this is a number, then the value | |||||
specifies the number of bytes; if it is a string, the value is passed to the | |||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults | |||||
to `'100kb'`. | |||||
##### type | |||||
The `type` option is used to determine what media type the middleware will | |||||
parse. This option can be a string, array of strings, or a function. If not | |||||
a function, `type` option is passed directly to the | |||||
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can | |||||
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime | |||||
type with a wildcard (like `*/*` or `text/*`). If a function, the `type` | |||||
option is called as `fn(req)` and the request is parsed if it returns a | |||||
truthy value. Defaults to `text/plain`. | |||||
##### verify | |||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, | |||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the | |||||
encoding of the request. The parsing can be aborted by throwing an error. | |||||
### bodyParser.urlencoded([options]) | |||||
Returns middleware that only parses `urlencoded` bodies and only looks at | |||||
requests where the `Content-Type` header matches the `type` option. This | |||||
parser accepts only UTF-8 encoding of the body and supports automatic | |||||
inflation of `gzip` and `deflate` encodings. | |||||
A new `body` object containing the parsed data is populated on the `request` | |||||
object after the middleware (i.e. `req.body`). This object will contain | |||||
key-value pairs, where the value can be a string or array (when `extended` is | |||||
`false`), or any type (when `extended` is `true`). | |||||
#### Options | |||||
The `urlencoded` function takes an optional `options` object that may contain | |||||
any of the following keys: | |||||
##### extended | |||||
The `extended` option allows to choose between parsing the URL-encoded data | |||||
with the `querystring` library (when `false`) or the `qs` library (when | |||||
`true`). The "extended" syntax allows for rich objects and arrays to be | |||||
encoded into the URL-encoded format, allowing for a JSON-like experience | |||||
with URL-encoded. For more information, please | |||||
[see the qs library](https://www.npmjs.org/package/qs#readme). | |||||
Defaults to `true`, but using the default has been deprecated. Please | |||||
research into the difference between `qs` and `querystring` and choose the | |||||
appropriate setting. | |||||
##### inflate | |||||
When set to `true`, then deflated (compressed) bodies will be inflated; when | |||||
`false`, deflated bodies are rejected. Defaults to `true`. | |||||
##### limit | |||||
Controls the maximum request body size. If this is a number, then the value | |||||
specifies the number of bytes; if it is a string, the value is passed to the | |||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults | |||||
to `'100kb'`. | |||||
##### parameterLimit | |||||
The `parameterLimit` option controls the maximum number of parameters that | |||||
are allowed in the URL-encoded data. If a request contains more parameters | |||||
than this value, a 413 will be returned to the client. Defaults to `1000`. | |||||
##### type | |||||
The `type` option is used to determine what media type the middleware will | |||||
parse. This option can be a string, array of strings, or a function. If not | |||||
a function, `type` option is passed directly to the | |||||
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can | |||||
be an extension name (like `urlencoded`), a mime type (like | |||||
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like | |||||
`*/x-www-form-urlencoded`). If a function, the `type` option is called as | |||||
`fn(req)` and the request is parsed if it returns a truthy value. Defaults | |||||
to `application/x-www-form-urlencoded`. | |||||
##### verify | |||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, | |||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the | |||||
encoding of the request. The parsing can be aborted by throwing an error. | |||||
## Errors | |||||
The middlewares provided by this module create errors depending on the error | |||||
condition during parsing. The errors will typically have a `status`/`statusCode` | |||||
property that contains the suggested HTTP response code, an `expose` property | |||||
to determine if the `message` property should be displayed to the client, a | |||||
`type` property to determine the type of error without matching against the | |||||
`message`, and a `body` property containing the read body, if available. | |||||
The following are the common errors emitted, though any error can come through | |||||
for various reasons. | |||||
### content encoding unsupported | |||||
This error will occur when the request had a `Content-Encoding` header that | |||||
contained an encoding but the "inflation" option was set to `false`. The | |||||
`status` property is set to `415`, the `type` property is set to | |||||
`'encoding.unsupported'`, and the `charset` property will be set to the | |||||
encoding that is unsupported. | |||||
### request aborted | |||||
This error will occur when the request is aborted by the client before reading | |||||
the body has finished. The `received` property will be set to the number of | |||||
bytes received before the request was aborted and the `expected` property is | |||||
set to the number of expected bytes. The `status` property is set to `400` | |||||
and `type` property is set to `'request.aborted'`. | |||||
### request entity too large | |||||
This error will occur when the request body's size is larger than the "limit" | |||||
option. The `limit` property will be set to the byte limit and the `length` | |||||
property will be set to the request body's length. The `status` property is | |||||
set to `413` and the `type` property is set to `'entity.too.large'`. | |||||
### request size did not match content length | |||||
This error will occur when the request's length did not match the length from | |||||
the `Content-Length` header. This typically occurs when the request is malformed, | |||||
typically when the `Content-Length` header was calculated based on characters | |||||
instead of bytes. The `status` property is set to `400` and the `type` property | |||||
is set to `'request.size.invalid'`. | |||||
### stream encoding should not be set | |||||
This error will occur when something called the `req.setEncoding` method prior | |||||
to this middleware. This module operates directly on bytes only and you cannot | |||||
call `req.setEncoding` when using this module. The `status` property is set to | |||||
`500` and the `type` property is set to `'stream.encoding.set'`. | |||||
### too many parameters | |||||
This error will occur when the content of the request exceeds the configured | |||||
`parameterLimit` for the `urlencoded` parser. The `status` property is set to | |||||
`413` and the `type` property is set to `'parameters.too.many'`. | |||||
### unsupported charset "BOGUS" | |||||
This error will occur when the request had a charset parameter in the | |||||
`Content-Type` header, but the `iconv-lite` module does not support it OR the | |||||
parser does not support it. The charset is contained in the message as well | |||||
as in the `charset` property. The `status` property is set to `415`, the | |||||
`type` property is set to `'charset.unsupported'`, and the `charset` property | |||||
is set to the charset that is unsupported. | |||||
### unsupported content encoding "bogus" | |||||
This error will occur when the request had a `Content-Encoding` header that | |||||
contained an unsupported encoding. The encoding is contained in the message | |||||
as well as in the `encoding` property. The `status` property is set to `415`, | |||||
the `type` property is set to `'encoding.unsupported'`, and the `encoding` | |||||
property is set to the encoding that is unsupported. | |||||
## Examples | |||||
### Express/Connect top-level generic | |||||
This example demonstrates adding a generic JSON and URL-encoded parser as a | |||||
top-level middleware, which will parse the bodies of all incoming requests. | |||||
This is the simplest setup. | |||||
```js | |||||
var express = require('express') | |||||
var bodyParser = require('body-parser') | |||||
var app = express() | |||||
// parse application/x-www-form-urlencoded | |||||
app.use(bodyParser.urlencoded({ extended: false })) | |||||
// parse application/json | |||||
app.use(bodyParser.json()) | |||||
app.use(function (req, res) { | |||||
res.setHeader('Content-Type', 'text/plain') | |||||
res.write('you posted:\n') | |||||
res.end(JSON.stringify(req.body, null, 2)) | |||||
}) | |||||
``` | |||||
### Express route-specific | |||||
This example demonstrates adding body parsers specifically to the routes that | |||||
need them. In general, this is the most recommended way to use body-parser with | |||||
Express. | |||||
```js | |||||
var express = require('express') | |||||
var bodyParser = require('body-parser') | |||||
var app = express() | |||||
// create application/json parser | |||||
var jsonParser = bodyParser.json() | |||||
// create application/x-www-form-urlencoded parser | |||||
var urlencodedParser = bodyParser.urlencoded({ extended: false }) | |||||
// POST /login gets urlencoded bodies | |||||
app.post('/login', urlencodedParser, function (req, res) { | |||||
res.send('welcome, ' + req.body.username) | |||||
}) | |||||
// POST /api/users gets JSON bodies | |||||
app.post('/api/users', jsonParser, function (req, res) { | |||||
// create user in req.body | |||||
}) | |||||
``` | |||||
### Change accepted type for parsers | |||||
All the parsers accept a `type` option which allows you to change the | |||||
`Content-Type` that the middleware will parse. | |||||
```js | |||||
var express = require('express') | |||||
var bodyParser = require('body-parser') | |||||
var app = express() | |||||
// parse various different custom JSON types as JSON | |||||
app.use(bodyParser.json({ type: 'application/*+json' })) | |||||
// parse some custom thing into a Buffer | |||||
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) | |||||
// parse an HTML body into a string | |||||
app.use(bodyParser.text({ type: 'text/html' })) | |||||
``` | |||||

Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa. | |||||
## Installation | |||||
This is a [Node.js](https://nodejs.org/en/) module available through the | |||||
[npm registry](https://www.npmjs.com/). Installation is done using the | |||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): | |||||
```bash | |||||
$ npm install bytes | |||||
``` | |||||
## Usage | |||||
```js | |||||
var bytes = require('bytes'); | |||||
``` | |||||
#### bytes.format(number value, [options]): string|null | |||||
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is | |||||
rounded. | |||||
**Arguments** | |||||
| Name | Type | Description | | |||||
|---------|----------|--------------------| | |||||
| value | `number` | Value in bytes | | |||||
| options | `Object` | Conversion options | | |||||
**Options** | |||||
| Property | Type | Description | | |||||
|-------------------|--------|-----------------------------------------------------------------------------------------| | |||||
| decimalPlaces | `number`|`null` | Maximum number of decimal places to include in output. Default value to `2`. | | |||||
| fixedDecimals | `boolean`|`null` | Whether to always display the maximum number of decimal places. Default value to `false` | | |||||
| thousandsSeparator | `string`|`null` | Example of values: `' '`, `','` and `.`... Default value to `''`. | | |||||
| unit | `string`|`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). | | |||||
| unitSeparator | `string`|`null` | Separator to use between number and unit. Default value to `''`. | | |||||
**Returns** | |||||
| Name | Type | Description | | |||||
|---------|------------------|-------------------------------------------------| | |||||
| results | `string`|`null` | Return null upon error. String value otherwise. | | |||||
**Example** | |||||
```js | |||||
bytes(1024); | |||||
// output: '1KB' | |||||
bytes(1000); | |||||
// output: '1000B' | |||||
bytes(1000, {thousandsSeparator: ' '}); | |||||
// output: '1 000B' | |||||
bytes(1024 * 1.7, {decimalPlaces: 0}); | |||||
// output: '2KB' | |||||
bytes(1024, {unitSeparator: ' '}); | |||||
// output: '1 KB' | |||||
``` | |||||
#### bytes.parse(string|number value): number|null | |||||
Parse the string value into an integer in bytes. If no unit is given, or `value` | |||||
is a number, it is assumed the value is in bytes. | |||||
Supported units and abbreviations are as follows and are case-insensitive: | |||||
* `b` for bytes | |||||
* `kb` for kilobytes | |||||
* `mb` for megabytes | |||||
* `gb` for gigabytes | |||||
* `tb` for terabytes | |||||
* `pb` for petabytes | |||||
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser. | |||||
**Arguments** | |||||
| Name | Type | Description | | |||||
|---------------|--------|--------------------| | |||||
| value | `string`|`number` | String to parse, or number in bytes. | | |||||
**Returns** | |||||
| Name | Type | Description | | |||||
|---------|-------------|-------------------------| | |||||
| results | `number`|`null` | Return null upon error. Value in bytes otherwise. | | |||||
**Example** | |||||
```js | |||||
bytes('1KB'); | |||||
// output: 1024 | |||||
bytes('1024'); | |||||
// output: 1024 | |||||
bytes(1024); | |||||
// output: 1KB | |||||

Create and parse HTTP `Content-Disposition` header | |||||
## Installation | |||||
```sh | |||||
$ npm install content-disposition | |||||
``` | |||||
## API | |||||
<!-- eslint-disable no-unused-vars --> | |||||
```js | |||||
var contentDisposition = require('content-disposition') | |||||
``` | |||||
### contentDisposition(filename, options) | |||||
Create an attachment `Content-Disposition` header value using the given file name, | |||||
if supplied. The `filename` is optional and if no file name is desired, but you | |||||
want to specify `options`, set `filename` to `undefined`. | |||||
<!-- eslint-disable no-undef --> | |||||
```js | |||||
res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf')) | |||||
``` | |||||
**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this | |||||
header through a means different from `setHeader` in Node.js, you'll want to specify | |||||
the `'binary'` encoding in Node.js. | |||||
#### Options | |||||
`contentDisposition` accepts these properties in the options object. | |||||
##### fallback | |||||
If the `filename` option is outside ISO-8859-1, then the file name is actually | |||||
stored in a supplemental field for clients that support Unicode file names and | |||||
a ISO-8859-1 version of the file name is automatically generated. | |||||
This specifies the ISO-8859-1 file name to override the automatic generation or | |||||
disables the generation all together, defaults to `true`. | |||||
- A string will specify the ISO-8859-1 file name to use in place of automatic | |||||
generation. | |||||
- `false` will disable including a ISO-8859-1 file name and only include the | |||||
Unicode version (unless the file name is already ISO-8859-1). | |||||
- `true` will enable automatic generation if the file name is outside ISO-8859-1. | |||||
If the `filename` option is ISO-8859-1 and this option is specified and has a | |||||
different value, then the `filename` option is encoded in the extended field | |||||
and this set as the fallback field, even though they are both ISO-8859-1. | |||||
##### type | |||||
Specifies the disposition type, defaults to `"attachment"`. This can also be | |||||
`"inline"`, or any other value (all values except inline are treated like | |||||
`attachment`, but can convey additional information if both parties agree to | |||||
it). The type is normalized to lower-case. | |||||
### contentDisposition.parse(string) | |||||
<!-- eslint-disable no-undef, no-unused-vars --> | |||||
```js | |||||
var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt') | |||||
``` | |||||
Parse a `Content-Disposition` header string. This automatically handles extended | |||||
("Unicode") parameters by decoding them and providing them under the standard | |||||
parameter name. This will return an object with the following properties (examples | |||||
are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`): | |||||
- `type`: The disposition type (always lower case). Example: `'attachment'` | |||||
- `parameters`: An object of the parameters in the disposition (name of parameter | |||||
always lower case and extended versions replace non-extended versions). Example: | |||||
`{filename: "€ rates.txt"}` | |||||
## Examples | |||||
### Send a file for download | |||||
```js | |||||
var contentDisposition = require('content-disposition') | |||||
var destroy = require('destroy') | |||||
var fs = require('fs') | |||||
var http = require('http') | |||||
var onFinished = require('on-finished') | |||||
var filePath = '/path/to/public/plans.pdf' | |||||
http.createServer(function onRequest (req, res) { | |||||
// set headers | |||||
res.setHeader('Content-Type', 'application/pdf') | |||||
res.setHeader('Content-Disposition', contentDisposition(filePath)) | |||||
// send file | |||||
var stream = fs.createReadStream(filePath) | |||||
stream.pipe(res) | |||||
onFinished(res, function () { | |||||
destroy(stream) | |||||
}) | |||||
}) | |||||
``` | |||||
## Testing | |||||
```sh | |||||
$ npm test | |||||
``` | |||||

Create and parse HTTP Content-Type header according to RFC 7231 | |||||
## Installation | |||||
```sh | |||||
$ npm install content-type | |||||
``` | |||||
## API | |||||
```js | |||||
var contentType = require('content-type') | |||||
``` | |||||
### contentType.parse(string) | |||||
```js | |||||
var obj = contentType.parse('image/svg+xml; charset=utf-8') | |||||
``` | |||||
Parse a content type string. This will return an object with the following | |||||
properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`): | |||||
- `type`: The media type (the type and subtype, always lower case). | |||||
Example: `'image/svg+xml'` | |||||
- `parameters`: An object of the parameters in the media type (name of parameter | |||||
always lower case). Example: `{charset: 'utf-8'}` | |||||
Throws a `TypeError` if the string is missing or invalid. | |||||
### contentType.parse(req) | |||||
```js | |||||
var obj = contentType.parse(req) | |||||
``` | |||||
Parse the `content-type` header from the given `req`. Short-cut for | |||||
`contentType.parse(req.headers['content-type'])`. | |||||
Throws a `TypeError` if the `Content-Type` header is missing or invalid. | |||||
### contentType.parse(res) | |||||
```js | |||||
var obj = contentType.parse(res) | |||||
``` | |||||
Parse the `content-type` header set on the given `res`. Short-cut for | |||||
`contentType.parse(res.getHeader('content-type'))`. | |||||
Throws a `TypeError` if the `Content-Type` header is missing or invalid. | |||||
### contentType.format(obj) | |||||
```js | |||||
var str = contentType.format({type: 'image/svg+xml'}) | |||||
``` | |||||
Format an object into a content type string. This will return a string of the | |||||
content type for the given object with the following properties (examples are | |||||
shown that produce the string `'image/svg+xml; charset=utf-8'`): | |||||
- `type`: The media type (will be lower-cased). Example: `'image/svg+xml'` | |||||
- `parameters`: An object of the parameters in the media type (name of the | |||||
parameter will be lower-cased). Example: `{charset: 'utf-8'}` | |||||
Throws a `TypeError` if the object contains an invalid type or parameter names. | |||||

Basic HTTP cookie parser and serializer for HTTP servers. | |||||
## Installation | |||||
```sh | |||||
$ npm install cookie | |||||
``` | |||||
## API | |||||
```js | |||||
var cookie = require('cookie'); | |||||
``` | |||||
### cookie.parse(str, options) | |||||
Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs. | |||||
The `str` argument is the string representing a `Cookie` header value and `options` is an | |||||
optional object containing additional parsing options. | |||||
```js | |||||
var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2'); | |||||
// { foo: 'bar', equation: 'E=mc^2' } | |||||
``` | |||||
#### Options | |||||
`cookie.parse` accepts these properties in the options object. | |||||
##### decode | |||||
Specifies a function that will be used to decode a cookie's value. Since the value of a cookie | |||||
has a limited character set (and must be a simple string), this function can be used to decode | |||||
a previously-encoded cookie value into a JavaScript string or other object. | |||||
The default function is the global `decodeURIComponent`, which will decode any URL-encoded | |||||
sequences into their byte representations. | |||||
**note** if an error is thrown from this function, the original, non-decoded cookie value will | |||||
be returned as the cookie's value. | |||||
### cookie.serialize(name, value, options) | |||||
Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the | |||||
name for the cookie, the `value` argument is the value to set the cookie to, and the `options` | |||||
argument is an optional object containing additional serialization options. | |||||
```js | |||||
var setCookie = cookie.serialize('foo', 'bar'); | |||||
// foo=bar | |||||
``` | |||||
#### Options | |||||
`cookie.serialize` accepts these properties in the options object. | |||||
##### domain | |||||
Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no | |||||
domain is set, and most clients will consider the cookie to apply to only the current domain. | |||||
##### encode | |||||
Specifies a function that will be used to encode a cookie's value. Since value of a cookie | |||||
has a limited character set (and must be a simple string), this function can be used to encode | |||||
a value into a string suited for a cookie's value. | |||||
The default function is the global `encodeURIComponent`, which will encode a JavaScript string | |||||
into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. | |||||
##### expires | |||||
Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1]. | |||||
By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and | |||||
will delete it on a condition like exiting a web browser application. | |||||
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and | |||||
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, | |||||
so if both are set, they should point to the same date and time. | |||||
##### httpOnly | |||||
Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy, | |||||
the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. | |||||
**note** be careful when setting this to `true`, as compliant clients will not allow client-side | |||||
JavaScript to see the cookie in `document.cookie`. | |||||
##### maxAge | |||||
Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2]. | |||||
The given number will be converted to an integer by rounding down. By default, no maximum age is set. | |||||
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and | |||||
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, | |||||
so if both are set, they should point to the same date and time. | |||||
##### path | |||||
Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path | |||||
is considered the ["default path"][rfc-6265-5.1.4]. | |||||
##### sameSite | |||||
Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7]. | |||||
- `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. | |||||
- `false` will not set the `SameSite` attribute. | |||||
- `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. | |||||
- `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. | |||||
- `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. | |||||
More information about the different enforcement levels can be found in | |||||
[the specification][rfc-6265bis-03-4.1.2.7]. | |||||
**note** This is an attribute that has not yet been fully standardized, and may change in the future. | |||||
This also means many clients may ignore this attribute until they understand it. | |||||
##### secure | |||||
Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy, | |||||
the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set. | |||||
**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to | |||||
the server in the future if the browser does not have an HTTPS connection. | |||||
## Example | |||||
The following example uses this module in conjunction with the Node.js core HTTP server | |||||
to prompt a user for their name and display it back on future visits. | |||||
```js | |||||
var cookie = require('cookie'); | |||||
var escapeHtml = require('escape-html'); | |||||
var http = require('http'); | |||||
var url = require('url'); | |||||
function onRequest(req, res) { | |||||
// Parse the query string | |||||
var query = url.parse(req.url, true, true).query; | |||||
if (query && query.name) { | |||||
// Set a new cookie with the name | |||||
res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), { | |||||
httpOnly: true, | |||||
maxAge: 60 * 60 * 24 * 7 // 1 week | |||||
})); | |||||
// Redirect back after setting cookie | |||||
res.statusCode = 302; | |||||
res.setHeader('Location', req.headers.referer || '/'); | |||||
res.end(); | |||||
return; | |||||
} | |||||
// Parse the cookies on the request | |||||
var cookies = cookie.parse(req.headers.cookie || ''); | |||||
// Get the visitor name set in the cookie | |||||
var name = cookies.name; | |||||
res.setHeader('Content-Type', 'text/html; charset=UTF-8'); | |||||
if (name) { | |||||
res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>'); | |||||
} else { | |||||
res.write('<p>Hello, new visitor!</p>'); | |||||
} | |||||
res.write('<form method="GET">'); | |||||
res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">'); | |||||
res.end('</form>'); | |||||
} | |||||
http.createServer(onRequest).listen(3000); | |||||

A tiny node.js debugging utility modelled after node core's debugging technique. | |||||
**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)** | |||||
## Installation | |||||
```bash | |||||
$ npm install debug | |||||
``` | |||||
## Usage | |||||
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. | |||||
Example _app.js_: | |||||
```js | |||||
var debug = require('debug')('http') | |||||
, http = require('http') | |||||
, name = 'My App'; | |||||
// fake app | |||||
debug('booting %s', name); | |||||
http.createServer(function(req, res){ | |||||
debug(req.method + ' ' + req.url); | |||||
res.end('hello\n'); | |||||
}).listen(3000, function(){ | |||||
debug('listening'); | |||||
}); | |||||
// fake worker of some kind | |||||
require('./worker'); | |||||
``` | |||||
Example _worker.js_: | |||||
```js | |||||
var debug = require('debug')('worker'); | |||||
setInterval(function(){ | |||||
debug('doing some work'); | |||||
}, 1000); | |||||
``` | |||||
The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: | |||||
![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) | |||||
![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) | |||||
#### Windows note | |||||
On Windows the environment variable is set using the `set` command. | |||||
```cmd | |||||
set DEBUG=*,-not_this | |||||
``` | |||||
Note that PowerShell uses different syntax to set environment variables. | |||||
```cmd | |||||
$env:DEBUG = "*,-not_this" | |||||
``` | |||||
Then, run the program to be debugged as usual. | |||||
## Millisecond diff | |||||
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. | |||||
![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) | |||||
When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: | |||||
![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) | |||||
## Conventions | |||||
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". | |||||
## Wildcards | |||||
The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. | |||||
You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". | |||||
## Environment Variables | |||||
When running through Node.js, you can set a few environment variables that will | |||||
change the behavior of the debug logging: | |||||
| Name | Purpose | | |||||
|-----------|-------------------------------------------------| | |||||
| `DEBUG` | Enables/disables specific debugging namespaces. | | |||||
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | | |||||
| `DEBUG_DEPTH` | Object inspection depth. | | |||||
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | | |||||
__Note:__ The environment variables beginning with `DEBUG_` end up being | |||||
converted into an Options object that gets used with `%o`/`%O` formatters. | |||||
See the Node.js documentation for | |||||
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) | |||||
for the complete list. | |||||
## Formatters | |||||
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: | |||||
| Formatter | Representation | | |||||
|-----------|----------------| | |||||
| `%O` | Pretty-print an Object on multiple lines. | | |||||
| `%o` | Pretty-print an Object all on a single line. | | |||||
| `%s` | String. | | |||||
| `%d` | Number (both integer and float). | | |||||
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | | |||||
| `%%` | Single percent sign ('%'). This does not consume an argument. | | |||||
### Custom formatters | |||||
You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: | |||||
```js | |||||
const createDebug = require('debug') | |||||
createDebug.formatters.h = (v) => { | |||||
return v.toString('hex') | |||||
} | |||||
// …elsewhere | |||||
const debug = createDebug('foo') | |||||
debug('this is hex: %h', new Buffer('hello world')) | |||||
// foo this is hex: 68656c6c6f20776f726c6421 +0ms | |||||
``` | |||||
## Browser support | |||||
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), | |||||
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), | |||||
if you don't want to build it yourself. | |||||
Debug's enable state is currently persisted by `localStorage`. | |||||
Consider the situation shown below where you have `worker:a` and `worker:b`, | |||||
and wish to debug both. You can enable this using `localStorage.debug`: | |||||
```js | |||||
localStorage.debug = 'worker:*' | |||||
``` | |||||
And then refresh the page. | |||||
```js | |||||
a = debug('worker:a'); | |||||
b = debug('worker:b'); | |||||
setInterval(function(){ | |||||
a('doing some work'); | |||||
}, 1000); | |||||
setInterval(function(){ | |||||
b('doing some work'); | |||||
}, 1200); | |||||
``` | |||||
#### Web Inspector Colors | |||||
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting | |||||
option. These are WebKit web inspectors, Firefox ([since version | |||||
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) | |||||
and the Firebug plugin for Firefox (any version). | |||||
Colored output looks something like: | |||||
![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) | |||||
## Output streams | |||||
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: | |||||
Example _stdout.js_: | |||||
```js | |||||
var debug = require('debug'); | |||||
var error = debug('app:error'); | |||||
// by default stderr is used | |||||
error('goes to stderr!'); | |||||
var log = debug('app:log'); | |||||
// set this namespace to log via console.log | |||||
log.log = console.log.bind(console); // don't forget to bind to console! | |||||
log('goes to stdout'); | |||||
error('still goes to stderr!'); | |||||
// set all output to go via console.info | |||||
// overrides all per-namespace log settings | |||||
debug.log = console.info.bind(console); | |||||
error('now goes to stdout via console.info'); | |||||
log('still goes to stdout, but via console.info now'); | |||||
``` | |||||

Deprecate all the things | |||||
> With great modules comes great responsibility; mark things deprecated! | |||||
## Install | |||||
This module is installed directly using `npm`: | |||||
```sh | |||||
$ npm install depd | |||||
``` | |||||
This module can also be bundled with systems like | |||||
[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/), | |||||
though by default this module will alter it's API to no longer display or | |||||
track deprecations. | |||||
## API | |||||
<!-- eslint-disable no-unused-vars --> | |||||
```js | |||||
var deprecate = require('depd')('my-module') | |||||
``` | |||||
This library allows you to display deprecation messages to your users. | |||||
This library goes above and beyond with deprecation warnings by | |||||
introspection of the call stack (but only the bits that it is interested | |||||
in). | |||||
Instead of just warning on the first invocation of a deprecated | |||||
function and never again, this module will warn on the first invocation | |||||
of a deprecated function per unique call site, making it ideal to alert | |||||
users of all deprecated uses across the code base, rather than just | |||||
whatever happens to execute first. | |||||
The deprecation warnings from this module also include the file and line | |||||
information for the call into the module that the deprecated function was | |||||
in. | |||||
**NOTE** this library has a similar interface to the `debug` module, and | |||||
this module uses the calling file to get the boundary for the call stacks, | |||||
so you should always create a new `deprecate` object in each file and not | |||||
within some central file. | |||||
### depd(namespace) | |||||
Create a new deprecate function that uses the given namespace name in the | |||||
messages and will display the call site prior to the stack entering the | |||||
file this function was called from. It is highly suggested you use the | |||||
name of your module as the namespace. | |||||
### deprecate(message) | |||||
Call this function from deprecated code to display a deprecation message. | |||||
This message will appear once per unique caller site. Caller site is the | |||||
first call site in the stack in a different file from the caller of this | |||||
function. | |||||
If the message is omitted, a message is generated for you based on the site | |||||
of the `deprecate()` call and will display the name of the function called, | |||||
similar to the name displayed in a stack trace. | |||||
### deprecate.function(fn, message) | |||||
Call this function to wrap a given function in a deprecation message on any | |||||
call to the function. An optional message can be supplied to provide a custom | |||||
message. | |||||
### deprecate.property(obj, prop, message) | |||||
Call this function to wrap a given property on object in a deprecation message | |||||
on any accessing or setting of the property. An optional message can be supplied | |||||
to provide a custom message. | |||||
The method must be called on the object where the property belongs (not | |||||
inherited from the prototype). | |||||
If the property is a data descriptor, it will be converted to an accessor | |||||
descriptor in order to display the deprecation message. | |||||
### process.on('deprecation', fn) | |||||
This module will allow easy capturing of deprecation errors by emitting the | |||||
errors as the type "deprecation" on the global `process`. If there are no | |||||
listeners for this type, the errors are written to STDERR as normal, but if | |||||
there are any listeners, nothing will be written to STDERR and instead only | |||||
emitted. From there, you can write the errors in a different format or to a | |||||
logging source. | |||||
The error represents the deprecation and is emitted only once with the same | |||||
rules as writing to STDERR. The error has the following properties: | |||||
- `message` - This is the message given by the library | |||||
- `name` - This is always `'DeprecationError'` | |||||
- `namespace` - This is the namespace the deprecation came from | |||||
- `stack` - This is the stack of the call to the deprecated thing | |||||
Example `error.stack` output: | |||||
``` | |||||
DeprecationError: my-cool-module deprecated oldfunction | |||||
at Object.<anonymous> ([eval]-wrapper:6:22) | |||||
at Module._compile (module.js:456:26) | |||||
at evalScript (node.js:532:25) | |||||
at startup (node.js:80:7) | |||||
at node.js:902:3 | |||||
``` | |||||
### process.env.NO_DEPRECATION | |||||
As a user of modules that are deprecated, the environment variable `NO_DEPRECATION` | |||||
is provided as a quick solution to silencing deprecation warnings from being | |||||
output. The format of this is similar to that of `DEBUG`: | |||||
```sh | |||||
$ NO_DEPRECATION=my-module,othermod node app.js | |||||
``` | |||||
This will suppress deprecations from being output for "my-module" and "othermod". | |||||
The value is a list of comma-separated namespaces. To suppress every warning | |||||
across all namespaces, use the value `*` for a namespace. | |||||
Providing the argument `--no-deprecation` to the `node` executable will suppress | |||||
all deprecations (only available in Node.js 0.8 or higher). | |||||
**NOTE** This will not suppress the deperecations given to any "deprecation" | |||||
event listeners, just the output to STDERR. | |||||
### process.env.TRACE_DEPRECATION | |||||
As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION` | |||||
is provided as a solution to getting more detailed location information in deprecation | |||||
warnings by including the entire stack trace. The format of this is the same as | |||||
`NO_DEPRECATION`: | |||||
```sh | |||||
$ TRACE_DEPRECATION=my-module,othermod node app.js | |||||
``` | |||||
This will include stack traces for deprecations being output for "my-module" and | |||||
"othermod". The value is a list of comma-separated namespaces. To trace every | |||||
warning across all namespaces, use the value `*` for a namespace. | |||||
Providing the argument `--trace-deprecation` to the `node` executable will trace | |||||
all deprecations (only available in Node.js 0.8 or higher). | |||||
**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`. | |||||
## Display | |||||
![message](files/message.png) | |||||
When a user calls a function in your library that you mark deprecated, they | |||||
will see the following written to STDERR (in the given colors, similar colors | |||||
and layout to the `debug` module): | |||||
``` | |||||
bright cyan bright yellow | |||||
| | reset cyan | |||||
| | | | | |||||
▼ ▼ ▼ ▼ | |||||
my-cool-module deprecated oldfunction [eval]-wrapper:6:22 | |||||
▲ ▲ ▲ ▲ | |||||
| | | | | |||||
namespace | | location of mycoolmod.oldfunction() call | |||||
| deprecation message | |||||
the word "deprecated" | |||||
``` | |||||
If the user redirects their STDERR to a file or somewhere that does not support | |||||
colors, they see (similar layout to the `debug` module): | |||||
``` | |||||
Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22 | |||||
▲ ▲ ▲ ▲ ▲ | |||||
| | | | | | |||||
timestamp of message namespace | | location of mycoolmod.oldfunction() call | |||||
| deprecation message | |||||
the word "deprecated" | |||||
``` | |||||
## Examples | |||||
### Deprecating all calls to a function | |||||
This will display a deprecated message about "oldfunction" being deprecated | |||||
from "my-module" on STDERR. | |||||
```js | |||||
var deprecate = require('depd')('my-cool-module') | |||||
// message automatically derived from function name | |||||
// Object.oldfunction | |||||
exports.oldfunction = deprecate.function(function oldfunction () { | |||||
// all calls to function are deprecated | |||||
}) | |||||
// specific message | |||||
exports.oldfunction = deprecate.function(function () { | |||||
// all calls to function are deprecated | |||||
}, 'oldfunction') | |||||
``` | |||||
### Conditionally deprecating a function call | |||||
This will display a deprecated message about "weirdfunction" being deprecated | |||||
from "my-module" on STDERR when called with less than 2 arguments. | |||||
```js | |||||
var deprecate = require('depd')('my-cool-module') | |||||
exports.weirdfunction = function () { | |||||
if (arguments.length < 2) { | |||||
// calls with 0 or 1 args are deprecated | |||||
deprecate('weirdfunction args < 2') | |||||
} | |||||
} | |||||
``` | |||||
When calling `deprecate` as a function, the warning is counted per call site | |||||
within your own module, so you can display different deprecations depending | |||||
on different situations and the users will still get all the warnings: | |||||
```js | |||||
var deprecate = require('depd')('my-cool-module') | |||||
exports.weirdfunction = function () { | |||||
if (arguments.length < 2) { | |||||
// calls with 0 or 1 args are deprecated | |||||
deprecate('weirdfunction args < 2') | |||||
} else if (typeof arguments[0] !== 'string') { | |||||
// calls with non-string first argument are deprecated | |||||
deprecate('weirdfunction non-string first arg') | |||||
} | |||||
} | |||||
``` | |||||
### Deprecating property access | |||||
This will display a deprecated message about "oldprop" being deprecated | |||||
from "my-module" on STDERR when accessed. A deprecation will be displayed | |||||
when setting the value and when getting the value. | |||||
```js | |||||
var deprecate = require('depd')('my-cool-module') | |||||
exports.oldprop = 'something' | |||||
// message automatically derives from property name | |||||
deprecate.property(exports, 'oldprop') | |||||
// explicit message | |||||
deprecate.property(exports, 'oldprop', 'oldprop >= 0.10') | |||||
``` | |||||

Destroy a stream. | |||||
This module is meant to ensure a stream gets destroyed, handling different APIs | |||||
and Node.js bugs. | |||||
## API | |||||
```js | |||||
var destroy = require('destroy') | |||||
``` | |||||
### destroy(stream) | |||||
Destroy the given stream. In most cases, this is identical to a simple | |||||
`stream.destroy()` call. The rules are as follows for a given stream: | |||||
1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()` | |||||
and add a listener to the `open` event to call `stream.close()` if it is | |||||
fired. This is for a Node.js bug that will leak a file descriptor if | |||||
`.destroy()` is called before `open`. | |||||
2. If the `stream` is not an instance of `Stream`, then nothing happens. | |||||
3. If the `stream` has a `.destroy()` method, then call it. | |||||
The function returns the `stream` passed in as the argument. | |||||
## Example | |||||
```js | |||||
var destroy = require('destroy') | |||||
var fs = require('fs') | |||||
var stream = fs.createReadStream('package.json') | |||||
// ... and later | |||||
destroy(stream) | |||||

Get the first event in a set of event emitters and event pairs, | |||||
then clean up after itself. | |||||
## Install | |||||
```sh | |||||
$ npm install ee-first | |||||
``` | |||||
## API | |||||
```js | |||||
var first = require('ee-first') | |||||
``` | |||||
### first(arr, listener) | |||||
Invoke `listener` on the first event from the list specified in `arr`. `arr` is | |||||
an array of arrays, with each array in the format `[ee, ...event]`. `listener` | |||||
will be called only once, the first time any of the given events are emitted. If | |||||
`error` is one of the listened events, then if that fires first, the `listener` | |||||
will be given the `err` argument. | |||||
The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the | |||||
first argument emitted from an `error` event, if applicable; `ee` is the event | |||||
emitter that fired; `event` is the string event name that fired; and `args` is an | |||||
array of the arguments that were emitted on the event. | |||||
```js | |||||
var ee1 = new EventEmitter() | |||||
var ee2 = new EventEmitter() | |||||
first([ | |||||
[ee1, 'close', 'end', 'error'], | |||||
[ee2, 'error'] | |||||
], function (err, ee, event, args) { | |||||
// listener invoked | |||||
}) | |||||
``` | |||||
#### .cancel() | |||||
The group of listeners can be cancelled before being invoked and have all the event | |||||
listeners removed from the underlying event emitters. | |||||
```js | |||||
var thunk = first([ | |||||
[ee1, 'close', 'end', 'error'], | |||||
[ee2, 'error'] | |||||
], function (err, ee, event, args) { | |||||
// listener invoked | |||||
}) | |||||
// cancel and clean up | |||||
thunk.cancel() | |||||
``` | |||||

Encode a URL to a percent-encoded form, excluding already-encoded sequences | |||||
## Installation | |||||
This is a [Node.js](https://nodejs.org/en/) module available through the | |||||
[npm registry](https://www.npmjs.com/). Installation is done using the | |||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): | |||||
```sh | |||||
$ npm install encodeurl | |||||
``` | |||||
## API | |||||
```js | |||||
var encodeUrl = require('encodeurl') | |||||
``` | |||||
### encodeUrl(url) | |||||
Encode a URL to a percent-encoded form, excluding already-encoded sequences. | |||||
This function will take an already-encoded URL and encode all the non-URL | |||||
code points (as UTF-8 byte sequences). This function will not encode the | |||||
"%" character unless it is not part of a valid sequence (`%20` will be | |||||
left as-is, but `%foo` will be encoded as `%25foo`). | |||||
This encode is meant to be "safe" and does not throw errors. It will try as | |||||
hard as it can to properly encode the given URL, including replacing any raw, | |||||
unpaired surrogate pairs with the Unicode replacement character prior to | |||||
encoding. | |||||
This function is _similar_ to the intrinsic function `encodeURI`, except it | |||||
will not encode the `%` character if that is part of a valid sequence, will | |||||
not encode `[` and `]` (for IPv6 hostnames) and will replace raw, unpaired | |||||
surrogate pairs with the Unicode replacement character (instead of throwing). | |||||
## Examples | |||||
### Encode a URL containing user-controled data | |||||
```js | |||||
var encodeUrl = require('encodeurl') | |||||
var escapeHtml = require('escape-html') | |||||
http.createServer(function onRequest (req, res) { | |||||
// get encoded form of inbound url | |||||
var url = encodeUrl(req.url) | |||||
// create html message | |||||
var body = '<p>Location ' + escapeHtml(url) + ' not found</p>' | |||||
// send a 404 | |||||
res.statusCode = 404 | |||||
res.setHeader('Content-Type', 'text/html; charset=UTF-8') | |||||
res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8'))) | |||||
res.end(body, 'utf-8') | |||||
}) | |||||
``` | |||||
### Encode a URL for use in a header field | |||||
```js | |||||
var encodeUrl = require('encodeurl') | |||||
var escapeHtml = require('escape-html') | |||||
var url = require('url') | |||||
http.createServer(function onRequest (req, res) { | |||||
// parse inbound url | |||||
var href = url.parse(req) | |||||
// set new host for redirect | |||||
href.host = 'localhost' | |||||
href.protocol = 'https:' | |||||
href.slashes = true | |||||
// create location header | |||||
var location = encodeUrl(url.format(href)) | |||||
// create html message | |||||
var body = '<p>Redirecting to new site: ' + escapeHtml(location) + '</p>' | |||||
// send a 301 | |||||
res.statusCode = 301 | |||||
res.setHeader('Content-Type', 'text/html; charset=UTF-8') | |||||
res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8'))) | |||||
res.setHeader('Location', location) | |||||
res.end(body, 'utf-8') | |||||
}) | |||||
``` | |||||
## Testing | |||||
```sh | |||||
$ npm test | |||||
$ npm run lint | |||||
``` | |||||

Create simple HTTP ETags | |||||
This module generates HTTP ETags (as defined in RFC 7232) for use in | |||||
HTTP responses. | |||||
## Installation | |||||
This is a [Node.js](https://nodejs.org/en/) module available through the | |||||
[npm registry](https://www.npmjs.com/). Installation is done using the | |||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): | |||||
```sh | |||||
$ npm install etag | |||||
``` | |||||
## API | |||||
<!-- eslint-disable no-unused-vars --> | |||||
```js | |||||
var etag = require('etag') | |||||
``` | |||||
### etag(entity, [options]) | |||||
Generate a strong ETag for the given entity. This should be the complete | |||||
body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By | |||||
default, a strong ETag is generated except for `fs.Stats`, which will | |||||
generate a weak ETag (this can be overwritten by `options.weak`). | |||||
<!-- eslint-disable no-undef --> | |||||
```js | |||||
res.setHeader('ETag', etag(body)) | |||||
``` | |||||
#### Options | |||||
`etag` accepts these properties in the options object. | |||||
##### weak | |||||
Specifies if the generated ETag will include the weak validator mark (that | |||||
is, the leading `W/`). The actual entity tag is the same. The default value | |||||
is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`. | |||||
## Testing | |||||
```sh | |||||
$ npm test | |||||
``` | |||||
## Benchmark | |||||
```bash | |||||
$ npm run-script bench | |||||

### Security Issues | |||||
If you discover a security vulnerability in Express, please see [Security Policies and Procedures](Security.md). | |||||
## Quick Start | |||||
The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below: | |||||
Install the executable. The executable's major version will match Express's: | |||||
```bash | |||||
$ npm install -g express-generator@4 | |||||
``` | |||||
Create the app: | |||||
```bash | |||||
$ express /tmp/foo && cd /tmp/foo | |||||
``` | |||||
Install dependencies: | |||||
```bash | |||||
$ npm install | |||||
``` | |||||
Start the server: | |||||
```bash | |||||
$ npm start | |||||
``` | |||||
View the website at: http://localhost:3000 | |||||
## Philosophy | |||||
The Express philosophy is to provide small, robust tooling for HTTP servers, making | |||||
it a great solution for single page applications, web sites, hybrids, or public | |||||
HTTP APIs. | |||||
Express does not force you to use any specific ORM or template engine. With support for over | |||||
14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js), | |||||
you can quickly craft your perfect framework. | |||||
## Examples | |||||
To view the examples, clone the Express repo and install the dependencies: | |||||
```bash | |||||
$ git clone git://github.com/expressjs/express.git --depth 1 | |||||
$ cd express | |||||
$ npm install | |||||
``` | |||||
Then run whichever example you want: | |||||
```bash | |||||
$ node examples/content-negotiation | |||||
``` | |||||
## Tests | |||||
To run the test suite, first install the dependencies, then run `npm test`: | |||||
```bash | |||||
$ npm install | |||||
$ npm test | |||||
``` | |||||
