Swap endianness in byte arrays. The input buffer is modified in place.

• MIT licensed
• Compatible with IE6+ and browsers that support ES3/ES5/ES6+
• Use it out of the box in Node.js
• Use it out of the box with TypeScript
• Use it with any byte offset
• Swap entire buffers
• Swap only a slice of the buffer

Install

npm install endianness

Use

Browser

Use endianness.umd.js:

<script src="endianness.umd.js"></script>
<script>
    var bytes = [64, 9, 33, 251, 84, 68, 45, 24]; 
    endianness(bytes, 8);
    console.log(bytes);
</script>

Or get it from the jsDelivr CDN:

<script src="https://cdn.jsdelivr.net/npm/endianness"></script>

Or get it from unpkg:

<script src="https://unpkg.com/endianness"></script>

Browser compatibility

endianness.umd.js is transpiled to ES3 and compatible with IE6+. Should work in all modern browsers that support ES3/ES5/ES6+.

Cross-browser tests powered by

Node

Require or import endianness from endianness:

import endianness from 'endianness';

// Swap endianness of one 64-bit value:
let bytes = [64, 9, 33, 251, 84, 68, 45, 24];
endianness(bytes, 8);

const endianness = require("endianness");

// Swap endianness of two 24-bit values:
let bytes = new Uint8Array(["00", "00", "80", "ff", "ff", "7f"]);
endianness(bytes, 3),

API

/**
 * Swap the byte ordering in a buffer. The buffer is modified in place.
 * @param {!Array<number|string>|!Uint8Array} bytes The bytes.
 * @param {number} offset The byte offset.
 * @param {number=} index The start index. Assumes 0.
 * @param {number=} end The end index. Assumes the buffer length.
 * @throws {Error} If the buffer length is not valid.
