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);Read our contributors document, submit an issue or talk to us on our Discord!
