@box2d/benchmark v0.10.0
@box2d/benchmark
A benchmark to compare various js/ts Box2D implementations.
Try it here: https://lusito.github.io/box2d.ts/
Fair Warning: In theory this can be added as a dependency to other physics libraries in order to run benchmarks against local code. But this has not been tested yet.

The @box2d Ecosystem
@box2d is a full-blown ecosystem for box2d for the JavaScript/TypeScript world. It can be used both in the browser and in node.js
Check out demos and compare performance here: https://lusito.github.io/box2d.ts/
Fair Warning: The whole @box2d ecosystem is in an early stage, so it will probably change a lot before we release the first stable version (1.0.0).
Other packages included in the ecosystem:
- Benchmark: Based on bench2d by joelgwebber
- Controllers: From the LiquidFun project
- Particles: Also from the LiquidFun project
- Lights: ported from LibGDX
- DebugDraw: Debug drawing using a canvas
- Testbed: A set of demos, partially ports of the original projects, partially new ones.
