Buffer From
A ponyfill for Buffer.from, uses native implementation if available.
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.bufferproperty of a TypedArray or ArrayBufferbyteOffset<Integer> Where to start copying fromarrayBuffer. Default:0length<Integer> How many bytes to copy fromarrayBuffer. 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 existingBufferto 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 ofstring. Default:'utf8'
Creates a new Buffer containing the given JavaScript string string. If
provided, the encoding parameter identifies the character encoding of
string.
