  • GitHub repo pFreak

    pFreak is a unit-level 2-in-1 JavaScript benchmarking and testing framework.

    Project mention: Show HN: Imba – I have spent 7 years creating a programming language for the web | | 2021-08-17

    I went through the same concerns and ended up building a little benchmarking tool for a simple reactive UI library I'm working on. It's not super user-friendly yet but doing a good job of profiling tasks.

    You can write custom benchmarks by clearly separating pre-setup work than relying on ready-made benchmarks (a bit of a pain initially, but helps a lot to fine-tune at unit-level going forward).

    It uses Chrome DevTools Protocol(CDP) through Puppeteer and allows to analyze execution durations separately (Scripting, Layout, Paint, etc).
