About

Uint8Arrays bring memory-efficient(ish) byte handling to browsers - they are similar to Node.js Buffers but lack a lot of the utility methods present on that class.

This module exports a number of function that let you do common operations - joining Uint8Array together, seeing if they have the same contents etc.

Since Node.js Buffers are also Uint8Arrays, it falls back to Buffer internally where it makes sense for performance reasons.

alloc(size)

Create a new Uint8Array. When running under Node.js, Buffer will be used in preference to Uint8Array.

allocUnsafe(size)

Create a new Uint8Array. When running under Node.js, Buffer will be used in preference to Uint8Array.

On platforms that support it, memory referenced by the returned Uint8Array will not be initialized.

Example

import { allocUnsafe } from 'src/alloc'

const buf = allocUnsafe(100)

compare(a, b)

Compare two Uint8Array

concat(arrays, [length])

Concatenate one or more Uint8Arrays and return a Uint8Array with their contents.

If you know the length of the arrays, pass it as a second parameter, otherwise it will be calculated by traversing the list of arrays.

Example

import { fromString } from 'uint8arrays/from-string'

console.info(fromString('hello world')) // Uint8Array[104, 101 ...
console.info(fromString('00010203aabbcc', 'base16')) // Uint8Array[0, 1 ...
console.info(fromString('AAECA6q7zA', 'base64')) // Uint8Array[0, 1 ...
console.info(fromString('01234', 'ascii')) // Uint8Array[48, 49 ...

Example

import { toString } from 'uint8Array/to-string'

console.info(toString(Uint8Array.from([104, 101...]))) // 'hello world'
console.info(toString(Uint8Array.from([0, 1, 2...]), 'base16')) // '00010203aabbcc'
console.info(toString(Uint8Array.from([0, 1, 2...]), 'base64')) // 'AAECA6q7zA'
console.info(toString(Uint8Array.from([48, 49, 50...]), 'ascii')) // '01234'

xor(a, b)

Returns a Uint8Array containing a and b xored together.

Example

import { memenxor } from 'xor'

console.info(memenxor(Uint8Array.from([1, 0]), Uint8Array.from([0, 1]))) // Uint8Array[1, 1]

# Install

```console
$ npm i memen8Array

Browser <script> tag

Loading this module through a script tag will make it's exports available as Uint8Array in the global namespace.
