# bl *(BufferList)*
|
||||
|
||||
|
||||
|
||||
**A Node.js Buffer list collector, reader and streamer thingy.**
|
||||
|
||||
[](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')
|
||||
|
||||
const bl = new BufferList()
|
||||
bl.append(Buffer.from('abcd'))
|
||||
bl.append(Buffer.from('efg'))
|
||||
bl.append('hi') // bl will also accept & convert Strings
|
||||
bl.append(Buffer.from('j'))
|
||||
bl.append(Buffer.from([ 0x3, 0x4 ]))
|
||||
|
||||
console.log(bl.length) // 12
|
||||
|
||||
console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
|
||||
console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
|
||||
console.log(bl.slice(3, 6).toString('ascii')) // 'def'
|
||||
console.log(bl.slice(3, 8).toString('ascii')) // 'defgh'
|
||||
console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
|
||||
|
||||
console.log(bl.indexOf('def')) // 3
|
||||
console.log(bl.indexOf('asdf')) // -1
|
||||
|
||||
// or just use toString!
|
||||
console.log(bl.toString()) // 'abcdefghij\u0003\u0004'
|
||||
console.log(bl.toString('ascii', 3, 8)) // 'defgh'
|
||||
console.log(bl.toString('ascii', 5, 10)) // 'fghij'
|
||||
|
||||
// other standard Buffer readables
|
||||
console.log(bl.readUInt16BE(10)) // 0x0304
|
||||
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 { BufferListStream } = require('bl')
|
||||
const fs = require('fs')
|
||||
|
||||
fs.createReadStream('README.md')
|
||||
.pipe(BufferListStream((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')
|
||||
const { BufferListStream } = require('bl')
|
||||
|
||||
const url = 'https://raw.github.com/rvagg/bl/master/README.md'
|
||||
|
||||
hyperquest(url).pipe(BufferListStream((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 { BufferListStream } = require('bl')
|
||||
const fs = require('fs')
|
||||
|
||||
var bl = new BufferListStream()
|
||||
bl.append(Buffer.from('abcd'))
|
||||
bl.append(Buffer.from('efg'))
|
||||
bl.append(Buffer.from('hi'))
|
||||
bl.append(Buffer.from('j'))
|
||||
|
||||
bl.pipe(fs.createWriteStream('gibberish.txt'))
|
||||
```

|

### new BufferList([ Buffer | Buffer array | BufferList | BufferList array | String ])
|
||||
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` objects.
|
||||
|
||||
`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
|
||||
const { BufferList } = require('bl')
|
||||
const bl = BufferList()
|
||||
|
||||
// equivalent to:
|
||||
|
||||
const { BufferList } = require('bl')
|
||||
const bl = new BufferList()
|
||||
```
|
||||
|
||||
--------------------------------------------------------
|
||||
<a name="isBufferList"></a>
|
||||
### BufferList.isBufferList(obj)
|
||||
Determines if the passed object is a `BufferList`. It will return `true` if the passed object is an instance of `BufferList` **or** `BufferListStream` and `false` otherwise.
|
||||
|
||||
N.B. this won't return `true` for `BufferList` or `BufferListStream` instances created by versions of this library before this static method was added.
|
||||
|
||||
--------------------------------------------------------
|
||||
<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="prepend"></a>
|
||||
### bl.prepend(Buffer | Buffer array | BufferList | BufferList array | String)
|
||||
`prepend(buffer)` adds an additional buffer or BufferList at the beginning of 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="indexOf"></a>
|
||||
### bl.indexOf(value[, byteOffset][, encoding])
|
||||
`get()` will return the byte at the specified index.
|
||||
`indexOf()` method returns the first index at which a given element can be found in the BufferList, or -1 if it is not present.
|
||||
|
||||
--------------------------------------------------------
|
||||
<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 BufferListStream()
|
||||
|
||||
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—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.readBigInt64BE(), bl.readBigInt64LE(), bl.readBigUInt64BE(), bl.readBigUInt64LE(), 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="ctorStream"></a>
|
||||
### new BufferListStream([ callback | Buffer | Buffer array | BufferList | BufferList array | String ])
|
||||
**BufferListStream** 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 **BufferListStream** instance.
|
||||
|
||||
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
|
||||
const { BufferListStream } = require('bl')
|
||||
const bl = BufferListStream()
|
||||
|
||||
// equivalent to:
|
||||
|
||||
const { BufferListStream } = require('bl')
|
||||
const bl = new BufferListStream()
|
||||
```
|
||||
|
||||
N.B. For backwards compatibility reasons, `BufferListStream` is the **default** export when you `require('bl')`:
|
||||
|
||||
```js
|
||||
const { BufferListStream } = require('bl')
|
||||
// equivalent to:
|
||||
const BufferListStream = require('bl')
|
||||
```
|
||||
|
||||
--------------------------------------------------------
|
||||
<a name="getBuffers"></a>
|
||||
### bl.getBuffers()
|
||||
|
||||
`getBuffers()` returns the internal list of buffers.

[saucelabs-url]: https://saucelabs.com/u/buffer
|
||||
|
||||
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.
|
||||
|
||||
## features
|
||||
|
||||
- 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 11+, iOS 11+, 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.
|
||||
|
||||
If you do not use a bundler, you can use the [standalone script](https://bundle.run/buffer).
|
||||
|
||||
## 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.
|
||||
|
||||
## JavaScript Standard Style
|
||||
|
||||
This module uses [JavaScript Standard Style](https://github.com/feross/standard).
|
||||
|
||||

|
||||
|
||||
To test that the code conforms to the style, `npm install` and run:
|
||||
|
||||
./node_modules/.bin/standard
