Javascript ArrayBuffer to Hex

Question

I\'ve got a Javascript ArrayBuffer that I would like to be converted into a hex string.

Anyone knows of a function that I can call or a pre written function already

Answer 1

I use this to hexdump ArrayBuffers the same way that Node dumps Buffers.

function pad(n: string, width: number, z = '0') {
    return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}
function hexdump(buf: ArrayBuffer) {
    let view = new Uint8Array(buf);
    let hex = Array.from(view).map(v => this.pad(v.toString(16), 2));
    return ``;
}

Example (with transpiled js version):

const buffer = new Uint8Array([ 4, 8, 12, 16 ]).buffer;
console.log(hexdump(buffer)); //
