# is [![Build Status](https://travis-ci.org/sindresorhus/is.svg?branch=master)](https://travis-ci.org/sindresorhus/is)
> Type check values: `is.string('🦄') //=> true`
<img src="header.gif" width="182" align="right">
## Install
```
$ npm install @sindresorhus/is
```
## Usage
```js
const is = require('@sindresorhus/is');
is('🦄');
//=> 'string'
is(new Map());
//=> 'Map'
is.number(6);
//=> true
```
When using `is` together with TypeScript, [type guards](http://www.typescriptlang.org/docs/handbook/advanced-types.html#type-guards-and-differentiating-types) are being used to infer the correct type inside if-else statements.
```ts
import is from '@sindresorhus/is';
const padLeft = (value: string, padding: string | number) => {
if (is.number(padding)) {
// `padding` is typed as `number`
return Array(padding + 1).join(' ') + value;
}
if (is.string(padding)) {
// `padding` is typed as `string`
return padding + value;
}
throw new TypeError(`Expected 'padding' to be of type 'string' or 'number', got '${is(padding)}'.`);
}
padLeft('🦄', 3);
//=> ' 🦄'
padLeft('🦄', '🌈');
//=> '🌈🦄'
```
## API
### is(value)
Returns the type of `value`.
Primitives are lowercase and object types are camelcase.
Example:
- `'undefined'`
- `'null'`
- `'string'`
- `'symbol'`
- `'Array'`
- `'Function'`
- `'Object'`
Note: It will throw an error if you try to feed it object-wrapped primitives, as that's a bad practice. For example `new String('foo')`.
### is.{method}
All the below methods accept a value and returns a boolean for whether the value is of the desired type.
#### Primitives
##### .undefined(value)
##### .null(value)
##### .string(value)
##### .number(value)
##### .boolean(value)
##### .symbol(value)
#### Built-in types
##### .array(value)
##### .function(value)
##### .buffer(value)
##### .object(value)
Keep in mind that [functions are objects too](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions).
##### .numericString(value)
Returns `true` for a string that represents a number. For example, `'42'` and `'-8'`.
Note: `'NaN'` returns `false`, but `'Infinity'` and `'-Infinity'` return `true`.
##### .regExp(value)
##### .date(value)
##### .error(value)
##### .nativePromise(value)
##### .promise(value)
Returns `true` for any object with a `.then()` and `.catch()` method. Prefer this one over `.nativePromise()` as you usually want to allow userland promise implementations too.
##### .generator(value)
Returns `true` for any object that implements its own `.next()` and `.throw()` methods and has a function definition for `Symbol.iterator`.
##### .generatorFunction(value)
##### .asyncFunction(value)
Returns `true` for any `async` function that can be called with the `await` operator.
```js
is.asyncFunction(async () => {});
// => true
is.asyncFunction(() => {});
// => false
```
##### .boundFunction(value)
Returns `true` for any `bound` function.
```js
is.boundFunction(() => {});
// => true
is.boundFunction(function () {}.bind(null));
// => true
is.boundFunction(function () {});
// => false
```
##### .map(value)
##### .set(value)
##### .weakMap(value)
##### .weakSet(value)
#### Typed arrays
##### .int8Array(value)
##### .uint8Array(value)
##### .uint8ClampedArray(value)
##### .int16Array(value)
##### .uint16Array(value)
##### .int32Array(value)
##### .uint32Array(value)
##### .float32Array(value)
##### .float64Array(value)
#### Structured data
##### .arrayBuffer(value)
##### .sharedArrayBuffer(value)
##### .dataView(value)
#### Emptiness
##### .emptyString(value)
Returns `true` if the value is a `string` and the `.length` is 0.
##### .nonEmptyString(value)
Returns `true` if the value is a `string` and the `.length` is more than 0.
##### .emptyStringOrWhitespace(value)
Returns `true` if `is.emptyString(value)` or if it's a `string` that is all whitespace.
##### .emptyArray(value)
Returns `true` if the value is an `Array` and the `.length` is 0.
##### .nonEmptyArray(value)
Returns `true` if the value is an `Array` and the `.length` is more than 0.
##### .emptyObject(value)
Returns `true` if the value is an `Object` and `Object.keys(value).length` is 0.
Please note that `Object.keys` returns only own enumerable properties. Hence something like this can happen:
```js
const object1 = {};
Object.defineProperty(object1, 'property1', {
value: 42,
writable: true,
enumerable: false,
configurable: true
});
is.emptyObject(object1);
// => true
```
##### .nonEmptyObject(value)
Returns `true` if the value is an `Object` and `Object.keys(value).length` is more than 0.
##### .emptySet(value)
Returns `true` if the value is a `Set` and the `.size` is 0.
##### .nonEmptySet(Value)
Returns `true` if the value is a `Set` and the `.size` is more than 0.
##### .emptyMap(value)
Returns `true` if the value is a `Map` and the `.size` is 0.
##### .nonEmptyMap(value)
Returns `true` if the value is a `Map` and the `.size` is more than 0.
#### Miscellaneous
##### .directInstanceOf(value, class)
Returns `true` if `value` is a direct instance of `class`.
```js
is.directInstanceOf(new Error(), Error);
//=> true
class UnicornError extends Error {}
is.directInstanceOf(new UnicornError(), Error);
//=> false
```
##### .urlInstance(value)
Returns `true` if `value` is an instance of the [`URL` class](https://developer.mozilla.org/en-US/docs/Web/API/URL).
```js
const url = new URL('https://example.com');
is.urlInstance(url);
//=> true
```
### .url(value)
Returns `true` if `value` is a URL string.
Note: this only does basic checking using the [`URL` class](https://developer.mozilla.org/en-US/docs/Web/API/URL) constructor.
```js
const url = 'https://example.com';
is.url(url);
//=> true
is.url(new URL(url));
//=> false
```
##### .truthy(value)
Returns `true` for all values that evaluate to true in a boolean context:
```js
is.truthy('🦄');
//=> true
is.truthy(undefined);
//=> false
```
##### .falsy(value)
Returns `true` if `value` is one of: `false`, `0`, `''`, `null`, `undefined`, `NaN`.
##### .nan(value)
##### .nullOrUndefined(value)
##### .primitive(value)
JavaScript primitives are as follows: `null`, `undefined`, `string`, `number`, `boolean`, `symbol`.
##### .integer(value)
##### .safeInteger(value)
Returns `true` if `value` is a [safe integer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/isSafeInteger).
##### .plainObject(value)
An object is plain if it's created by either `{}`, `new Object()`, or `Object.create(null)`.
##### .iterable(value)
##### .asyncIterable(value)
##### .class(value)
Returns `true` for instances created by a class.
##### .typedArray(value)
##### .arrayLike(value)
A `value` is array-like if it is not a function and has a `value.length` that is a safe integer greater than or equal to 0.
```js
is.arrayLike(document.forms);
//=> true
function foo() {
is.arrayLike(arguments);
//=> true
}
foo();
```
##### .inRange(value, range)
Check if `value` (number) is in the given `range`. The range is an array of two values, lower bound and upper bound, in no specific order.
```js
is.inRange(3, [0, 5]);
is.inRange(3, [5, 0]);
is.inRange(0, [-2, 2]);
```
##### .inRange(value, upperBound)
Check if `value` (number) is in the range of `0` to `upperBound`.
```js
is.inRange(3, 10);
```
##### .domElement(value)
Returns `true` if `value` is a DOM Element.
##### .nodeStream(value)
Returns `true` if `value` is a Node.js [stream](https://nodejs.org/api/stream.html).
```js
const fs = require('fs');
is.nodeStream(fs.createReadStream('unicorn.png'));
//=> true
```
##### .observable(value)
Returns `true` if `value` is an `Observable`.
```js
const {Observable} = require('rxjs');
is.observable(new Observable());
//=> true
```
##### .infinite(value)
Check if `value` is `Infinity` or `-Infinity`.
##### .even(value)
Returns `true` if `value` is an even integer.
##### .odd(value)
Returns `true` if `value` is an odd integer.
##### .any(predicate, ...values)
Returns `true` if **any** of the input `values` returns true in the `predicate`:
```js
is.any(is.string, {}, true, '🦄');
//=> true
is.any(is.boolean, 'unicorns', [], new Map());
//=> false
```
##### .all(predicate, ...values)
Returns `true` if **all** of the input `values` returns true in the `predicate`:
```js
is.all(is.object, {}, new Map(), new Set());
//=> true
is.all(is.string, '🦄', [], 'unicorns');
//=> false
```
## FAQ
### Why yet another type checking module?
There are hundreds of type checking modules on npm, unfortunately, I couldn't find any that fit my needs:
- Includes both type methods and ability to get the type
- Types of primitives returned as lowercase and object types as camelcase
- Covers all built-ins
- Unsurprising behavior
- Well-maintained
- Comprehensive test suite
For the ones I found, pick 3 of these.
The most common mistakes I noticed in these modules was using `instanceof` for type checking, forgetting that functions are objects, and omitting `symbol` as a primitive.

# abbrev-js
Just like [ruby's Abbrev](http://apidock.com/ruby/Abbrev).
Usage:
var abbrev = require("abbrev");
abbrev("foo", "fool", "folding", "flop");
// returns:
{ fl: 'flop'
, flo: 'flop'
, flop: 'flop'
, fol: 'folding'
, fold: 'folding'
, foldi: 'folding'
, foldin: 'folding'
, folding: 'folding'
, foo: 'foo'
, fool: 'fool'
}
This is handy for command-line scripts, or other cases where you want to be able to accept shorthands.

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/
```

# ansi-align
> align-text with ANSI support for CLIs
[![Build Status](https://travis-ci.org/nexdrew/ansi-align.svg?branch=master)](https://travis-ci.org/nexdrew/ansi-align)
[![Coverage Status](https://coveralls.io/repos/github/nexdrew/ansi-align/badge.svg?branch=master)](https://coveralls.io/github/nexdrew/ansi-align?branch=master)
[![Standard Version](https://img.shields.io/badge/release-standard%20version-brightgreen.svg)](https://github.com/conventional-changelog/standard-version)
[![Greenkeeper badge](https://badges.greenkeeper.io/nexdrew/ansi-align.svg)](https://greenkeeper.io/)
Easily center- or right- align a block of text, carefully ignoring ANSI escape codes.
E.g. turn this:
<img width="281" alt="ansi text block no alignment :(" src="https://cloud.githubusercontent.com/assets/1929625/14937509/7c3076dc-0ed7-11e6-8c16-4f6a4ccc8346.png">
Into this:
<img width="278" alt="ansi text block center aligned!" src="https://cloud.githubusercontent.com/assets/1929625/14937510/7c3ca0b0-0ed7-11e6-8f0a-541ca39b6e0a.png">
## Install
```sh
npm install --save ansi-align
```
```js
var ansiAlign = require('ansi-align')
```
## API
### `ansiAlign(text, [opts])`
Align the given text per the line with the greatest [`string-width`](https://github.com/sindresorhus/string-width), returning a new string (or array).
#### Arguments
- `text`: required, string or array
The text to align. If a string is given, it will be split using either the `opts.split` value or `'\n'` by default. If an array is given, a different array of modified strings will be returned.
- `opts`: optional, object
Options to change behavior, see below.
#### Options
- `opts.align`: string, default `'center'`
The alignment mode. Use `'center'` for center-alignment, `'right'` for right-alignment, or `'left'` for left-alignment. Note that the given `text` is assumed to be left-aligned already, so specifying `align: 'left'` just returns the `text` as is (no-op).
- `opts.split`: string or RegExp, default `'\n'`
The separator to use when splitting the text. Only used if text is given as a string.
- `opts.pad`: string, default `' '`
The value used to left-pad (prepend to) lines of lesser width. Will be repeated as necessary to adjust alignment to the line with the greatest width.
### `ansiAlign.center(text)`
Alias for `ansiAlign(text, { align: 'center' })`.
### `ansiAlign.right(text)`
Alias for `ansiAlign(text, { align: 'right' })`.
### `ansiAlign.left(text)`
Alias for `ansiAlign(text, { align: 'left' })`, which is a no-op.
## Similar Packages
- [`center-align`](https://github.com/jonschlinkert/center-align): Very close to this package, except it doesn't support ANSI codes.
- [`left-pad`](https://github.com/camwest/left-pad): Great for left-padding but does not support center alignment or ANSI codes.
- Pretty much anything by the [chalk](https://github.com/chalk) team

# string-width [![Build Status](https://travis-ci.org/sindresorhus/string-width.svg?branch=master)](https://travis-ci.org/sindresorhus/string-width)
> Get the visual width of a string - the number of columns required to display it
Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
Useful to be able to measure the actual width of command-line output.
## Install
```
$ npm install string-width
```
## Usage
```js
const stringWidth = require('string-width');
stringWidth('古');
//=> 2
stringWidth('\u001b[1m古\u001b[22m');
//=> 2
stringWidth('a');
//=> 1
stringWidth('\u001B]8;;https://github.com\u0007Click\u001B]8;;\u0007');
// => 5
```

## Usage
```js
const ansiRegex = require('ansi-regex');
ansiRegex().test('\u001B[4mcake\u001B[0m');
//=> true
ansiRegex().test('cake');
//=> false
'\u001B[4mcake\u001B[0m'.match(ansiRegex());

Returns a regex for matching ANSI escape codes.
#### options
##### onlyFirst
Type: `boolean`<br>
Default: `false` *(Matches any ANSI escape codes in a string)*
Match only the first ANSI escape.
## FAQ
### Why do you test for codes not in the ECMA 48 standard?
Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
## Install
```
$ npm install ansi-styles
```
## Usage
```js
const style = require('ansi-styles');
console.log(`${style.green.open}Hello world!${style.green.close}`);
// Color conversion between 16/256/truecolor
// NOTE: If conversion goes to 16 colors or 256 colors, the original color
// may be degraded to fit that color palette. This means terminals
// that do not support 16 million colors will best-match the
// original color.
console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
```
## API
Each style has an `open` and `close` property.
## Styles
### Modifiers
- `reset`
- `bold`
- `dim`
- `italic` *(Not widely supported)*
- `underline`
- `inverse`
- `hidden`
- `strikethrough` *(Not widely supported)*
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `gray` ("bright black")
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`
- `cyanBright`
- `whiteBright`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright`
- `bgRedBright`
- `bgGreenBright`
- `bgYellowBright`
- `bgBlueBright`
- `bgMagentaBright`
- `bgCyanBright`
- `bgWhiteBright`
## Advanced usage
By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
- `style.modifier`
- `style.color`
- `style.bgColor`
###### Example
```js
console.log(style.color.green.open);
```
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
###### Example
```js
console.log(style.codes.get(36));
//=> 39
```
## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
To use these, call the associated conversion function with the intended output, for example:
```js
style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
```

anymatch [![Build Status](https://travis-ci.org/micromatch/anymatch.svg?branch=master)](https://travis-ci.org/micromatch/anymatch) [![Coverage Status](https://img.shields.io/coveralls/micromatch/anymatch.svg?branch=master)](https://coveralls.io/r/micromatch/anymatch?branch=master)
======
Javascript module to match a string against a regular expression, glob, string,
or function that takes the string as an argument and returns a truthy or falsy
value. The matcher can also be an array of any or all of these. Useful for
allowing a very flexible user-defined config to define things like file paths.
__Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See https://github.com/micromatch/micromatch#backslashes for more information.__
Usage
-----
```sh
npm install anymatch
```
#### anymatch(matchers, testString, [returnIndex], [options])
* __matchers__: (_Array|String|RegExp|Function_)
String to be directly matched, string with glob patterns, regular expression
test, function that takes the testString as an argument and returns a truthy
value if it should be matched, or an array of any number and mix of these types.
* __testString__: (_String|Array_) The string to test against the matchers. If
passed as an array, the first element of the array will be used as the
`testString` for non-function matchers, while the entire array will be applied
as the arguments for function matchers.
* __options__: (_Object_ [optional]_) Any of the [picomatch](https://github.com/micromatch/picomatch#options) options.
* __returnIndex__: (_Boolean [optional]_) If true, return the array index of
the first matcher that that testString matched, or -1 if no match, instead of a
boolean result.
```js
const anymatch = require('anymatch');
const matchers = [ 'path/to/file.js', 'path/anyjs/**/*.js', /foo.js$/, string => string.includes('bar') && string.length > 10 ] ;
anymatch(matchers, 'path/to/file.js'); // true
anymatch(matchers, 'path/anyjs/baz.js'); // true
anymatch(matchers, 'path/to/foo.js'); // true
anymatch(matchers, 'path/to/bar.js'); // true
anymatch(matchers, 'bar.js'); // false
// returnIndex = true
anymatch(matchers, 'foo.js', {returnIndex: true}); // 2
anymatch(matchers, 'path/anyjs/foo.js', {returnIndex: true}); // 1
// any picomatc
// using globs to match directories and their children
anymatch('node_modules', 'node_modules'); // true
anymatch('node_modules', 'node_modules/somelib/index.js'); // false
anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
const matcher = anymatch(matchers);
['foo.js', 'bar.js'].filter(matcher); // [ 'foo.js' ]
anymatch master*
```
#### anymatch(matchers)
You can also pass in only your matcher(s) to get a curried function that has
already been bound to the provided matching criteria. This can be used as an
`Array#filter` callback.
```js
var matcher = anymatch(matchers);
matcher('path/to/file.js'); // true
matcher('path/anyjs/baz.js', true); // 1
['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
```
Changelog
----------
[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
- **v3.0:** Removed `startIndex` and `endIndex` arguments. Node 8.x-only.
- **v2.0:** [micromatch](https://github.com/jonschlinkert/micromatch) moves away from minimatch-parity and inline with Bash. This includes handling backslashes differently (see https://github.com/micromatch/micromatch#backslashes for more information).
- **v1.2:** anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
for glob pattern matching. Issues with glob pattern matching should be
reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

# balanced-match
Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
## Example
Get the first matching pair of braces:
```js
var balanced = require('balanced-match');
console.log(balanced('{', '}', 'pre{in{nested}}post'));
console.log(balanced('{', '}', 'pre{first}between{second}post'));
console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre { in{nest} } post'));
```
The matches are:
```bash
$ node example.js
{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
{ start: 3,
end: 9,
pre: 'pre',
body: 'first',
post: 'between{second}post' }
{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
```
## API
### var m = balanced(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
object with those keys:
* **start** the index of the first match of `a`
* **end** the index of the matching `b`
* **pre** the preamble, `a` and `b` not included
* **body** the match, `a` and `b` not included
* **post** the postscript, `a` and `b` not included
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
### var r = balanced.range(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
array with indexes: `[ <a index>, <b index> ]`.
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.
## Installation
With [npm](https://npmjs.org) do:
```bash
npm install balanced-match
```

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' }))
```
