hexdump.js

| Built by Root

Given an ArrayBuffer, will create string output similar to the unix hexdump command.

For example, the text of "Hello, World!\n" looks something like this:

        0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F
0000000 48 65 6c 6c 6f 2c 20 57 6f 72 6c 64 21 0a
000000e

Usage

So far it just does one thing: print an ArrayBuffer in hex, with a header:

Node.js (and WebPack)

var hexdump = require('hexdump.js').hexdump;

var str = hexdump(new Uint8Array([ 0, 1, 2, 127, 254, 255 ]));

console.log(str);

Vanilla JS (Browser)

<script src="https://unpkg.com/@root/hexdump/dist/hexdump.js"></script>

console.log(window.hexdump(new Uint8Array([0, 1, 2, 127, 254, 255])));
