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

npm i b4a

React Native

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:

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

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)

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.
