Installation

npm install --save buffer-from

Usage

const bufferFrom = require('buffer-from')

console.log(bufferFrom([1, 2, 3, 4]))
//=> <Buffer 01 02 03 04>

const arr = new Uint8Array([1, 2, 3, 4])
console.log(bufferFrom(arr.buffer, 1, 2))
//=> <Buffer 02 03>

console.log(bufferFrom('test', 'utf8'))
//=> <Buffer 74 65 73 74>

const buf = bufferFrom('test')
console.log(bufferFrom(buf))
//=> <Buffer 74 65 73 74>

API

bufferFrom(array)

array <Array>

Allocates a new Buffer using an array of octets.

bufferFrom(arrayBuffer[, byteOffset[, length]])

arrayBuffer <ArrayBuffer> The .buffer property of a TypedArray or ArrayBuffer
byteOffset <Integer> Where to start copying from arrayBuffer. Default: 0
length <Integer> How many bytes to copy from arrayBuffer. Default: arrayBuffer.length - byteOffset

When passed a reference to the .buffer property of a TypedArray instance, the newly created Buffer will share the same allocated memory as the TypedArray.

The optional byteOffset and length arguments specify a memory range within the arrayBuffer that will be shared by the Buffer.

bufferFrom(buffer)

buffer <Buffer> An existing Buffer to copy data from

Copies the passed buffer data onto a new Buffer instance.

bufferFrom(string[, encoding])

string <String> A string to encode.
encoding <String> The encoding of string. Default: 'utf8'

Creates a new Buffer containing the given JavaScript string string. If provided, the encoding parameter identifies the character encoding of string.
