Hi everyone, I just released AQE Light, a high-performance CSS selector engine.

Instead of traditional tree-walking, it projects the DOM into a memory-mapped structure using 64-bit BigInt masks. This turns selector matching into simple bitwise math, making it significantly faster for apps with large DOMs or high query frequency.

- ✅ Zero dependencies

- ✅ Up to 10x faster than native methods in warm queries

- ✅ Lightweight & easy to drop into any project.

It’s a flat, memory-mapped selector engine. No recursive tree-climbing, just fast bitwise operations. Perfect for dashboards, design tools, or any project where milliseconds matter.

Find it on NPMJS search for AQE-Light
