Buffer for Array

Buffer for Array (B4A) provides a set of functions for bridging the gap between the Node.js Buffer class and the Uint8Array class. A browser compatibility layer is also included, making it possible to use B4A in both Node.js and browsers without having to worry about whether you're dealing with buffers or typed arrays.

Installation

``sh
npm i b4a
`

$3

When imported from React Native b4a will make use of react-native-b4a for optimised buffer operations when available. All you need to do is install it:

`sh
npm i react-native-b4a
`

API

#### b4a.isBuffer(value)

See https://nodejs.org/api/buffer.html#static-method-bufferisbufferobj

This will also return true when passed a Uint8Array.

#### b4a.isEncoding(encoding)

See https://nodejs.org/api/buffer.html#static-method-bufferisencodingencoding

#### b4a.alloc(size[, fill[, encoding]])

See https://nodejs.org/api/buffer.html#static-method-bufferallocsize-fill-encoding

#### b4a.allocUnsafe(size)

See https://nodejs.org/api/buffer.html#static-method-bufferallocunsafesize

#### b4a.allocUnsafeSlow(size)

See https://nodejs.org/api/buffer.html#static-method-bufferallocunsafeslowsize

#### b4a.byteLength(string)

See https://nodejs.org/api/buffer.html#static-method-bufferbytelengthstring-encoding

#### b4a.compare(buf1, buf2)

See https://nodejs.org/api/buffer.html#static-method-buffercomparebuf1-buf2

#### b4a.concat(buffers[, totalLength])

See https://nodejs.org/api/buffer.html#static-method-bufferconcatlist-totallength

#### b4a.copy(source, target[, targetStart[, sourceStart[, sourceEnd]]])

See https://nodejs.org/api/buffer.html#bufcopytarget-targetstart-sourcestart-sourceend

#### b4a.equals(buf1, buf2)

See https://nodejs.org/api/buffer.html#bufequalsotherbuffer

#### b4a.fill(buffer, value[, offset[, end]][, encoding])

See https://nodejs.org/api/buffer.html#buffillvalue-offset-end-encoding

#### b4a.from(array)

See https://nodejs.org/api/buffer.html#static-method-bufferfromarray

#### b4a.from(arrayBuffer[, byteOffset[, length]])

See https://nodejs.org/api/buffer.html#static-method-bufferfromarraybuffer-byteoffset-length

#### b4a.from(buffer)

See https://nodejs.org/api/buffer.html#static-method-bufferfrombuffer

#### b4a.from(string[, encoding])

See https://nodejs.org/api/buffer.html#static-method-bufferfromstring-encoding

#### b4a.includes(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#bufincludesvalue-byteoffset-encoding

#### b4a.indexOf(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#bufindexofvalue-byteoffset-encoding

#### b4a.lastIndexOf(buffer, value[, byteOffset][, encoding])

See https://nodejs.org/api/buffer.html#buflastindexofvalue-byteoffset-encoding

#### b4a.swap16(buffer)

See https://nodejs.org/api/buffer.html#bufswap16

#### b4a.swap32(buffer)

See https://nodejs.org/api/buffer.html#bufswap32

#### b4a.swap64(buffer)

See https://nodejs.org/api/buffer.html#bufswap64

#### b4a.toBuffer(buffer)

Convert a buffer to its canonical representation. In Node.js, the canonical representation is a Buffer. In the browser, the canonical representation is a Uint8Array.

#### b4a.toString(buffer, [encoding[, start[, end]]])

See https://nodejs.org/api/buffer.html#buftostringencoding-start-end

#### b4a.write(buffer, string[, offset[, length]][, encoding])
