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.
