Swap endianness in byte arrays. The input array is modified in-place.

• Works in Node.js and in the browser
• Works with any byte offset

Install

npm install endianness

Browser

Use the compiled file in the /dist folder:

<script src="endianness.min.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@5/dist/endianness.min.js"></script>

Example

const endianness = require("endianness");

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

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

API

/**
 * Swap the endianness of units of information in a byte array.
 * The original array is modified in place.
 * @param {!Array<number|string>|!Uint8Array} bytes The bytes.
 * @param {number} offset The number of bytes of each unit of information.
 * @throws {Error} If the byte array length is not valid.
