Summary

Delta encoding utilities for efficient repeated state transmission. Detects changes between successive values and encodes differences rather than full values.

Install

bun add @suaveplan/bitpacker-delta

Usage

import { DeltaManager, calculateStringDiff, applyStringDiff, numberXor } from "@suaveplan/bitpacker-delta";

// Change detection
const dm = new DeltaManager();
dm.detectChanges({ x: 1, y: 2 }); // returns { x: 1, y: 2 }
dm.detectChanges({ x: 1, y: 2 }); // returns undefined (no change)
dm.detectChanges({ x: 1, y: 3 }); // returns { x: 1, y: 3 }

// String diff
const diff = calculateStringDiff("hello world", "hello there");
// { prefixLen: 6, suffixLen: 0, middleLen: 5, middle: "there" }
const reconstructed = applyStringDiff("hello world", diff);
// "hello there"

// Numeric XOR delta
const delta = numberXor(3.14159, 2.71828);
