JS Reactivity Benchmark

$ pnpm bench

Features

• Configurable dependency graph: graph shape, density, read rate are all adjustable
• Easily add new benchmarks and frameworks
• Supports dynamic reactive nodes
• Framework agnostic. Simple API to test new reactive frameworks
• Forces garbage collection between each test
• Outputs a csv file for easy integration with other tools

Current reactivity benchmarks (S.js, CellX) are focused on creation time, and update time for a static graph. Additionally, existing benchmarks aren't very configurable, and don't test for dynamic dependencies. We've created a new benchmark that allows library authors to compare their frameworks against each other, and against the existing benchmarks, as well as against a new configurable benchmark with dynamically changing sources.

We're also working on enabling consistent logging and efficient tracking of GC time across all benchmarks.
