XDelta3-Node

A minimal xdelta3 native binding for NodeJs.

Getting started

It's an esm module and have minimum interface with sensible defaults set in the binding itself.

import {encodeSync, decodeSync} from "@chainsafe/xdelta3-node";

const state1 = Buffer.from("initial state", "utf8");
const state2 = Buffer.from("initial state + updates", "utf8");

// Get a Uint8Array binary patch
const patch = encodeSync(state1, state2);


// Apply the patch to reproduce the state2
const reproducedState = decodeSync(state1, patch);

Prerequisites

• :gear: NodeJS (LTS)
• :toolbox: Npm
