base64-js
=========
`base64-js` does basic base64 encoding/decoding in pure JS.
[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
[![testling badge](https://ci.testling.com/beatgammit/base64-js.png)](https://ci.testling.com/beatgammit/base64-js)
Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
## install
With [npm](https://npmjs.org) do:
`npm install base64-js` and `var base64js = require('base64-js')`
For use in web browsers do:
`<script src="base64js.min.js"></script>`
## methods
`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
* `byteLength` - Takes a base64 string and returns length of byte array
* `toByteArray` - Takes a base64 string and returns a byte array
* `fromByteArray` - Takes a byte array and returns a base64 string

# bl *(BufferList)*
[![Build Status](https://travis-ci.org/rvagg/bl.svg?branch=master)](https://travis-ci.org/rvagg/bl)
**A Node.js Buffer list collector, reader and streamer thingy.**
[![NPM](https://nodei.co/npm/bl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/bl/)
[![NPM](https://nodei.co/npm-dl/bl.png?months=6&height=3)](https://nodei.co/npm/bl/)
**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
```js
const BufferList = require('bl')
var bl = new BufferList()
bl.append(new Buffer('abcd'))
bl.append(new Buffer('efg'))
bl.append('hi') // bl will also accept & convert Strings
bl.append(new Buffer('j'))
bl.append(new Buffer([ 0x3, 0x4 ]))
console.log(bl.length) // 12

console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'

console.log(bl.toString('ascii', 3, 8)) // 'defgh'
console.log(bl.toString('ascii', 5, 10)) // 'fghij'

console.log(bl.readUInt16LE(10)) // 0x0403
```
Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
```js
const bl = require('bl')
, fs = require('fs')
fs.createReadStream('README.md')
.pipe(bl(function (err, data) { // note 'new' isn't strictly required
// `data` is a complete Buffer object containing the full data
console.log(data.toString())
}))
```
Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
```js
const hyperquest = require('hyperquest')
, bl = require('bl')
, url = 'https://raw.github.com/rvagg/bl/master/README.md'
hyperquest(url).pipe(bl(function (err, data) {
console.log(data.toString())
}))
```
Or, use it as a readable stream to recompose a list of Buffers to an output source:
```js
const BufferList = require('bl')
, fs = require('fs')
var bl = new BufferList()
bl.append(new Buffer('abcd'))
bl.append(new Buffer('efg'))
bl.append(new Buffer('hi'))
bl.append(new Buffer('j'))
bl.pipe(fs.createWriteStream('gibberish.txt'))
```

--------------------------------------------------------
<a name="ctor"></a>
### new BufferList([ callback | Buffer | Buffer array | BufferList | BufferList array | String ])
The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
```js
var bl = require('bl')
var myinstance = bl()
// equivalent to:
var BufferList = require('bl')
var myinstance = new BufferList()
```
--------------------------------------------------------
<a name="length"></a>
### bl.length
Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
--------------------------------------------------------
<a name="append"></a>
### bl.append(Buffer | Buffer array | BufferList | BufferList array | String)
`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained.
--------------------------------------------------------
<a name="get"></a>
### bl.get(index)
`get()` will return the byte at the specified index.
--------------------------------------------------------
<a name="slice"></a>
### bl.slice([ start, [ end ] ])
`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
--------------------------------------------------------
<a name="shallowSlice"></a>
### bl.shallowSlice([ start, [ end ] ])
`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
No copies will be performed. All buffers in the result share memory with the original list.
--------------------------------------------------------
<a name="copy"></a>
### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
--------------------------------------------------------
<a name="duplicate"></a>
### bl.duplicate()
`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
```js
var bl = new BufferList()
bl.append('hello')
bl.append(' world')
bl.append('\n')
bl.duplicate().pipe(process.stdout, { end: false })
console.log(bl.toString())
```
--------------------------------------------------------
<a name="consume"></a>
### bl.consume(bytes)
`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
--------------------------------------------------------
<a name="toString"></a>
### bl.toString([encoding, [ start, [ end ]]])
`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
--------------------------------------------------------
<a name="readXX"></a>
### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
--------------------------------------------------------
<a name="streams"></a>
### Streams
**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance.

# Buffer Alloc Unsafe
A [ponyfill](https://ponyfill.com) for `Buffer.allocUnsafe`.
Works as Node.js: `v7.0.0` <br>
Works on Node.js: `v0.10.0`
## Installation
```sh
npm install --save buffer-alloc-unsafe
```
## Usage
```js
const allocUnsafe = require('buffer-alloc-unsafe')
console.log(allocUnsafe(10))
//=> <Buffer 78 0c 80 03 01 00 00 00 05 00>
console.log(allocUnsafe(10))
//=> <Buffer 58 ed bf 5f ff 7f 00 00 01 00>
console.log(allocUnsafe(10))
//=> <Buffer 50 0c 80 03 01 00 00 00 0a 00>
allocUnsafe(-10)
//=> RangeError: "size" argument must not be negative
```
## API
### allocUnsafe(size)
- `size` &lt;Integer&gt; The desired length of the new `Buffer`
Allocates a new *non-zero-filled* `Buffer` of `size` bytes. The `size` must be
less than or equal to the value of `buffer.kMaxLength` and greater than or equal
to zero. Otherwise, a `RangeError` is thrown.

## API
### alloc(size[, fill[, encoding]])
- `size` &lt;Integer&gt; The desired length of the new `Buffer`
- `fill` &lt;String&gt; | &lt;Buffer&gt; | &lt;Integer&gt; A value to pre-fill the new `Buffer` with. **Default:** `0`
- `encoding` &lt;String&gt; If `fill` is a string, this is its encoding. **Default:** `'utf8'`
Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the `Buffer` will be zero-filled.

# buffer-crc32
[![Build Status](https://secure.travis-ci.org/brianloveswords/buffer-crc32.png?branch=master)](http://travis-ci.org/brianloveswords/buffer-crc32)
crc32 that works with binary data and fancy character sets, outputs
buffer, signed or unsigned data and has tests.
Derived from the sample CRC implementation in the PNG specification: http://www.w3.org/TR/PNG/#D-CRCAppendix
# install
```
npm install buffer-crc32
```
# example
```js
var crc32 = require('buffer-crc32');
// works with buffers

```
# tests
This was tested against the output of zlib's crc32 method. You can run
the tests with`npm test` (requires tap)
# see also
https://github.com/alexgorbatchev/node-crc, `crc.buffer.crc32` also
supports buffer inputs and return unsigned ints (thanks @tjholowaychuk).

# Buffer Fill
A [ponyfill](https://ponyfill.com) for `Buffer.fill`.
Works as Node.js: `v6.4.0` <br>
Works on Node.js: `v0.10.0`
## Installation
```sh
npm install --save buffer-fill
```
## Usage
```js
const fill = require('buffer-fill')
const buf = Buffer.allocUnsafe(5)
console.log(buf.fill(8))
//=> <Buffer 08 08 08 08 08>
console.log(buf.fill(9, 2, 4))
//=> <Buffer 08 08 09 09 08>
console.log(buf.fill('linus', 'latin1'))
//=> <Buffer 6c 69 6e 75 73>
console.log(buf.fill('\u0222'))
//=> <Buffer c8 a2 c8 a2 c8>
```
## API
### fill(buf, value[, offset[, end]][, encoding])
- `value` &lt;String&gt; | &lt;Buffer&gt; | &lt;Integer&gt; The value to fill `buf` with
- `offset` &lt;Integer&gt; Where to start filling `buf`. **Default:** `0`
- `end` &lt;Integer&gt; Where to stop filling `buf` (not inclusive). **Default:** `buf.length`
- `encoding` &lt;String&gt; If `value` is a string, this is its encoding. **Default:** `'utf8'`
- Return: &lt;Buffer&gt; A reference to `buf`
Fills `buf` with the specified `value`. If the `offset` and `end` are not given,
the entire `buf` will be filled. This is meant to be a small simplification to
allow the creation and filling of a `Buffer` to be done on a single line.
If the final write of a `fill()` operation falls on a multi-byte character, then
only the first bytes of that character that fit into `buf` are written.

With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
The goal is to provide an API that is 100% identical to
[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.

- Manipulate binary data like a boss, in all browsers!
- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
- Excellent browser support (Chrome, Firefox, Edge, Safari 9+, IE 11, iOS 9+, Android, etc.)
- Preserves Node API exactly, with one minor difference (see below)
- Square-bracket `buf[4]` notation works!
- Does not modify any browser prototypes or put anything on `window`
- Comprehensive test suite (including all buffer tests from node.js core)
## install
To use this module directly (without browserify), install it:
```bash
npm install buffer
```
This module was previously called **native-buffer-browserify**, but please use **buffer**
from now on.
A standalone bundle is available [here](https://wzrd.in/standalone/buffer), for non-browserify users.
## usage
The module's API is identical to node's `Buffer` API. Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.
As mentioned above, `require('buffer')` or use the `Buffer` global with
[browserify](http://browserify.org) and this module will automatically be included
in your bundle. Almost any npm module will work in the browser, even if it assumes that
the node `Buffer` API will be available.
To depend on this module explicitly (without browserify), require it like this:
```js
var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
```
To require this module explicitly, use `require('buffer/')` which tells the node.js module
lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
instead of the **node.js core** module named `buffer`!
## how does it work?
The Buffer constructor returns instances of `Uint8Array` that have their prototype
changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
so the returned instances will have all the node `Buffer` methods and the
`Uint8Array` methods. Square bracket notation works as expected -- it returns a
single octet.
The `Uint8Array` prototype remains unmodified.
## tracking the latest node api
This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
API is considered **stable** in the
[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
so it is unlikely that there will ever be breaking changes.
Nonetheless, when/if the Buffer API changes in node, this module's API will change
accordingly.

## conversion packages
### convert typed array to buffer
Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
### convert buffer to typed array
`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
### convert blob to buffer
Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
### convert buffer to blob
To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
```js
var blob = new Blob([ buffer ])
```
Optionally, specify a mimetype:
```js
var blob = new Blob([ buffer ], { type: 'text/html' })
```
### convert arraybuffer to buffer
To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
```js
var buffer = Buffer.from(arrayBuffer)
```
### convert buffer to arraybuffer
To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
```js
var arrayBuffer = buffer.buffer.slice(
buffer.byteOffset, buffer.byteOffset + buffer.byteLength
)
```
Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
## performance
See perf tests in `/perf`.
`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
which is included to compare against.
NOTE: Performance has improved since these benchmarks were taken. PR welcome to update the README.

## Testing the project
First, install the project:
npm install
Then, to run tests in Node.js, run:
npm run test-node
To test locally in a browser, you can run:
npm run test-browser-es5-local # For ES5 browsers that don't support ES6
npm run test-browser-es6-local # For ES6 compliant browsers
This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap).
To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
npm test
This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files.

[![Join the chat at https://gitter.im/tj/commander.js](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/tj/commander.js?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/tj/commander).
[API documentation](http://tj.github.com/commander.js/)
## Installation
$ npm install commander
## Option parsing
Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.0.1')
.option('-p, --peppers', 'Add peppers')
.option('-P, --pineapple', 'Add pineapple')
.option('-b, --bbq-sauce', 'Add bbq sauce')
.option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
.parse(process.argv);
console.log('you ordered a pizza with:');
if (program.peppers) console.log(' - peppers');
if (program.pineapple) console.log(' - pineapple');
if (program.bbqSauce) console.log(' - bbq');
console.log(' - %s cheese', program.cheese);
```
Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
## Coercion
```js
function range(val) {
return val.split('..').map(Number);
}
function list(val) {
return val.split(',');
}
function collect(val, memo) {
memo.push(val);
return memo;
}
function increaseVerbosity(v, total) {
return total + 1;
}
program
.version('0.0.1')
.usage('[options] <file ...>')
.option('-i, --integer <n>', 'An integer argument', parseInt)
.option('-f, --float <n>', 'A float argument', parseFloat)
.option('-r, --range <a>..<b>', 'A range', range)
.option('-l, --list <items>', 'A list', list)
.option('-o, --optional [value]', 'An optional value')
.option('-c, --collect [value]', 'A repeatable value', collect, [])
.option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
.parse(process.argv);
console.log(' int: %j', program.integer);
console.log(' float: %j', program.float);
console.log(' optional: %j', program.optional);
program.range = program.range || [];
console.log(' range: %j..%j', program.range[0], program.range[1]);
console.log(' list: %j', program.list);
console.log(' collect: %j', program.collect);
console.log(' verbosity: %j', program.verbose);
console.log(' args: %j', program.args);
```
## Regular Expression
```js
program
.version('0.0.1')
.option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
.option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
.parse(process.argv);
console.log(' size: %j', program.size);
console.log(' drink: %j', program.drink);
```
## Variadic arguments
The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to
append `...` to the argument name. Here is an example:
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.0.1')
.command('rmdir <dir> [otherDirs...]')
.action(function (dir, otherDirs) {
console.log('rmdir %s', dir);
if (otherDirs) {
otherDirs.forEach(function (oDir) {
console.log('rmdir %s', oDir);
});
}
});
program.parse(process.argv);
```
An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed
to your action as demonstrated above.
## Specify the argument syntax
```js
#!/usr/bin/env node
var program = require('../');
program
.version('0.0.1')
.arguments('<cmd> [env]')
.action(function (cmd, env) {
cmdValue = cmd;
envValue = env;
});
program.parse(process.argv);
if (typeof cmdValue === 'undefined') {
console.error('no command given!');
process.exit(1);
}
console.log('command:', cmdValue);
console.log('environment:', envValue || "no environment given");
```
## Git-style sub-commands
```js
// file: ./examples/pm
var program = require('..');
program
.version('0.0.1')
.command('install [name]', 'install one or more packages')
.command('search [query]', 'search with optional query')
.command('list', 'list packages installed')
.parse(process.argv);
```
When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.
The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
### `--harmony`
You can enable `--harmony` option in two ways:
* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version dont support this pattern.
* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
## Automated --help
The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
```
$ ./examples/pizza --help
Usage: pizza [options]
An application for pizzas ordering
Options:
-h, --help output usage information
-V, --version output the version number
-p, --peppers Add peppers
-P, --pineapple Add pineapple
-b, --bbq Add bbq sauce
-c, --cheese <type> Add the specified type of cheese [marble]
-C, --no-cheese You do not want any cheese
```
## Custom help
You can display arbitrary `-h, --help` information
by listening for "--help". Commander will automatically
exit once you are done so that the remainder of your program
does not execute causing undesired behaviours, for example
in the following executable "stuff" will not output when
`--help` is used.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.0.1')
.option('-f, --foo', 'enable some foo')
.option('-b, --bar', 'enable some bar')
.option('-B, --baz', 'enable some baz');
// must be before .parse() since
// node's emit() is immediate
program.on('--help', function(){
console.log(' Examples:');
console.log('');
console.log(' $ custom-help --help');
console.log(' $ custom-help -h');
console.log('');
});
program.parse(process.argv);
console.log('stuff');
```
Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
```
Usage: custom-help [options]
Options:
-h, --help output usage information
-V, --version output the version number
-f, --foo enable some foo
-b, --bar enable some bar
-B, --baz enable some baz
Examples:
$ custom-help --help
$ custom-help -h
```
## .outputHelp()
Output help information without exiting.
If you want to display help by default (e.g. if no command was provided), you can use something like:
```js
var program = require('commander');
program
.version('0.0.1')
.command('getstream [url]', 'get stream URL')
.parse(process.argv);
if (!process.argv.slice(2).length) {
program.outputHelp();
}
```
## .help()
Output help information and exit immediately.
## Examples
```js
var program = require('commander');
program
.version('0.0.1')
.option('-C, --chdir <path>', 'change the working directory')
.option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
.option('-T, --no-tests', 'ignore test hook')

# file-type [![Build Status](https://travis-ci.org/sindresorhus/file-type.svg?branch=master)](https://travis-ci.org/sindresorhus/file-type)
> Detect the file type of a Buffer/Uint8Array
The file type is detected by checking the [magic number](http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
## Install
```
$ npm install file-type
```
## Usage
##### Node.js
```js
const readChunk = require('read-chunk');
const fileType = require('file-type');
const buffer = readChunk.sync('unicorn.png', 0, 4100);
fileType(buffer);
//=> {ext: 'png', mime: 'image/png'}
```
Or from a remote location:
```js
const http = require('http');
const fileType = require('file-type');
const url = 'http://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
http.get(url, res => {
res.once('data', chunk => {
res.destroy();
console.log(fileType(chunk));
//=> {ext: 'gif', mime: 'image/gif'}
});
});
```
##### Browser
```js
const xhr = new XMLHttpRequest();
xhr.open('GET', 'unicorn.png');
xhr.responseType = 'arraybuffer';
xhr.onload = () => {
fileType(new Uint8Array(this.response));
//=> {ext: 'png', mime: 'image/png'}
};
xhr.send();
```
## API
### fileType(input)
Returns an `Object` with:
- `ext` - One of the [supported file types](#supported-file-types)
- `mime` - The [MIME type](http://en.wikipedia.org/wiki/Internet_media_type)
Or `null` when no match.
#### input
Type: `Buffer` `Uint8Array`
It only needs the first 4100 bytes.

# file-type [![Build Status](https://travis-ci.org/sindresorhus/file-type.svg?branch=master)](https://travis-ci.org/sindresorhus/file-type)
> Detect the file type of a Buffer/Uint8Array
The file type is detected by checking the [magic number](http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
## Install
```
$ npm install --save file-type
```
## Usage
##### Node.js
```js
const readChunk = require('read-chunk'); // npm install read-chunk
const fileType = require('file-type');
const buffer = readChunk.sync('unicorn.png', 0, 262);
fileType(buffer);
//=> {ext: 'png', mime: 'image/png'}
```
or from a remote location:
```js
const http = require('http');
const fileType = require('file-type');
const url = 'http://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
http.get(url, res => {
res.once('data', chunk => {
res.destroy();
console.log(fileType(chunk));
//=> {ext: 'gif', mime: 'image/gif'}
});
});
```
##### Browser
```js
const xhr = new XMLHttpRequest();
xhr.open('GET', 'unicorn.png');
xhr.responseType = 'arraybuffer';
xhr.onload = () => {
fileType(new Uint8Array(this.response));
//=> {ext: 'png', mime: 'image/png'}
};
xhr.send();
```
## API
### fileType(buffer)
Returns an `Object` (or `null` when no match) with:
- `ext` - one of the [supported file types](#supported-file-types)
- `mime` - the [MIME type](http://en.wikipedia.org/wiki/Internet_media_type)
#### buffer
Type: `Buffer` `Uint8Array`
It only needs the first 262 bytes.

# file-type [![Build Status](https://travis-ci.org/sindresorhus/file-type.svg?branch=master)](https://travis-ci.org/sindresorhus/file-type)
> Detect the file type of a Buffer/Uint8Array
The file type is detected by checking the [magic number](http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
## Install
```
$ npm install --save file-type
```
## Usage
##### Node.js
```js
const readChunk = require('read-chunk'); // npm install read-chunk
const fileType = require('file-type');
const buffer = readChunk.sync('unicorn.png', 0, 262);
fileType(buffer);
//=> {ext: 'png', mime: 'image/png'}
```
or from a remote location:
```js
const http = require('http');
const fileType = require('file-type');
const url = 'http://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
http.get(url, res => {
res.once('data', chunk => {
res.destroy();
console.log(fileType(chunk));
//=> {ext: 'gif', mime: 'image/gif'}
});
});
```
##### Browser
```js
const xhr = new XMLHttpRequest();
xhr.open('GET', 'unicorn.png');
xhr.responseType = 'arraybuffer';
xhr.onload = () => {
fileType(new Uint8Array(this.response));
//=> {ext: 'png', mime: 'image/png'}
};
xhr.send();
```
## API
### fileType(buffer)
Returns an `Object` (or `null` when no match) with:
- `ext` - one of the [supported file types](#supported-file-types)
- `mime` - the [MIME type](http://en.wikipedia.org/wiki/Internet_media_type)
#### buffer
Type: `Buffer` `Uint8Array`
It only needs the first 262 bytes.

# end-of-stream
A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
npm install end-of-stream
## Usage
Simply pass a stream and a callback to the `eos`.
Both legacy streams, streams2 and stream3 are supported.
``` js
var eos = require('end-of-stream');
eos(readableStream, function(err) {
// this will be set to the stream instance
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended', this === readableStream);
});
eos(writableStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished', this === writableStream);
});
eos(duplexStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended and finished', this === duplexStream);
});
eos(duplexStream, {readable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished but might still be readable');
});
eos(duplexStream, {writable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended but might still be writable');
});
eos(readableStream, {error:false}, function(err) {
// do not treat emit('error', err) as a end-of-stream
});
```

# fd-slicer
[![Build Status](https://travis-ci.org/andrewrk/node-fd-slicer.svg?branch=master)](https://travis-ci.org/andrewrk/node-fd-slicer)
Safe `fs.ReadStream` and `fs.WriteStream` using the same fd.
Let's say that you want to perform a parallel upload of a file to a remote
server. To do this, we want to create multiple read streams. The first thing
you might think of is to use the `{start: 0, end: 0}` API of
`fs.createReadStream`. This gives you two choices:
0. Use the same file descriptor for all `fs.ReadStream` objects.
0. Open the file multiple times, resulting in a separate file descriptor
for each read stream.
Neither of these are acceptable options. The first one is a severe bug,
because the API docs for `fs.write` state:
> Note that it is unsafe to use `fs.write` multiple times on the same file
> without waiting for the callback. For this scenario, `fs.createWriteStream`
> is strongly recommended.
`fs.createWriteStream` will solve the problem if you only create one of them
for the file descriptor, but it will exhibit this unsafety if you create
multiple write streams per file descriptor.
The second option suffers from a race condition. For each additional time the
file is opened after the first, it is possible that the file is modified. So
in our parallel uploading example, we might upload a corrupt file that never
existed on the client's computer.
This module solves this problem by providing `createReadStream` and
`createWriteStream` that operate on a shared file descriptor and provides
the convenient stream API while still allowing slicing and dicing.
This module also gives you some additional power that the builtin
`fs.createWriteStream` do not give you. These features are:
* Emitting a 'progress' event on write.
* Ability to set a maximum size and emit an error if this size is exceeded.
* Ability to create an `FdSlicer` instance from a `Buffer`. This enables you
to provide API for handling files as well as buffers using the same API.
## Usage
```js
var fdSlicer = require('fd-slicer');
var fs = require('fs');
fs.open("file.txt", 'r', function(err, fd) {
if (err) throw err;
var slicer = fdSlicer.createFromFd(fd);
var firstPart = slicer.createReadStream({start: 0, end: 100});
var secondPart = slicer.createReadStream({start: 100});
var firstOut = fs.createWriteStream("first.txt");
var secondOut = fs.createWriteStream("second.txt");
firstPart.pipe(firstOut);
secondPart.pipe(secondOut);
});
```
You can also create from a buffer:
```js
var fdSlicer = require('fd-slicer');
var slicer = FdSlicer.createFromBuffer(someBuffer);
var firstPart = slicer.createReadStream({start: 0, end: 100});
var secondPart = slicer.createReadStream({start: 100});
var firstOut = fs.createWriteStream("first.txt");
var secondOut = fs.createWriteStream("second.txt");
firstPart.pipe(firstOut);
secondPart.pipe(secondOut);
```
## API Documentation
### fdSlicer.createFromFd(fd, [options])
```js
var fdSlicer = require('fd-slicer');
fs.open("file.txt", 'r', function(err, fd) {
if (err) throw err;
var slicer = fdSlicer.createFromFd(fd);
// ...
});
```
Make sure `fd` is a properly initialized file descriptor. If you want to
use `createReadStream` make sure you open it for reading and if you want
to use `createWriteStream` make sure you open it for writing.
`options` is an optional object which can contain:
* `autoClose` - if set to `true`, the file descriptor will be automatically
closed once the last stream that references it is closed. Defaults to
`false`. `ref()` and `unref()` can be used to increase or decrease the
reference count, respectively.
### fdSlicer.createFromBuffer(buffer, [options])
```js
var fdSlicer = require('fd-slicer');
var slicer = fdSlicer.createFromBuffer(someBuffer);
// ...
```
`options` is an optional object which can contain:
* `maxChunkSize` - A `Number` of bytes. see `createReadStream()`.
If falsey, defaults to unlimited.
#### Properties
##### fd
The file descriptor passed in. `undefined` if created from a buffer.
#### Methods
##### createReadStream(options)
Available `options`:
* `start` - Number. The offset into the file to start reading from. Defaults
to 0.
* `end` - Number. Exclusive upper bound offset into the file to stop reading
from.
* `highWaterMark` - Number. The maximum number of bytes to store in the
internal buffer before ceasing to read from the underlying resource.
Defaults to 16 KB.
* `encoding` - String. If specified, then buffers will be decoded to strings
using the specified encoding. Defaults to `null`.
The ReadableStream that this returns has these additional methods:
* `destroy(err)` - stop streaming. `err` is optional and is the error that
will be emitted in order to cause the streaming to stop. Defaults to
`new Error("stream destroyed")`.
If `maxChunkSize` was specified (see `createFromBuffer()`), the read stream
will provide chunks of at most that size. Normally, the read stream provides
the entire range requested in a single chunk, but this can cause performance
problems in some circumstances.
See [thejoshwolfe/yauzl#87](https://github.com/thejoshwolfe/yauzl/issues/87).
##### createWriteStream(options)
Available `options`:
* `start` - Number. The offset into the file to start writing to. Defaults to
0.
* `end` - Number. Exclusive upper bound offset into the file. If this offset
is reached, the write stream will emit an 'error' event and stop functioning.
In this situation, `err.code === 'ETOOBIG'`. Defaults to `Infinity`.
* `highWaterMark` - Number. Buffer level when `write()` starts returning
false. Defaults to 16KB.
* `decodeStrings` - Boolean. Whether or not to decode strings into Buffers
before passing them to` _write()`. Defaults to `true`.
The WritableStream that this returns has these additional methods:
* `destroy()` - stop streaming
And these additional properties:
* `bytesWritten` - number of bytes written to the stream
And these additional events:
* 'progress' - emitted when `bytesWritten` changes.
##### read(buffer, offset, length, position, callback)
Equivalent to `fs.read`, but with concurrency protection.
`callback` must be defined.
##### write(buffer, offset, length, position, callback)
Equivalent to `fs.write`, but with concurrency protection.
`callback` must be defined.
##### ref()
Increase the `autoClose` reference count by 1.
##### unref()
Decrease the `autoClose` reference count by 1.
#### Events
##### 'error'
Emitted if `fs.close` returns an error when auto closing.
##### 'close'
Emitted when fd-slicer closes the file descriptor due to `autoClose`. Never
emitted if created from a buffer.
