Reactopt is a CLI tool that audits React applications for unnecessary component re-rendering by launching the app in a browser via Puppeteer and analyzing user interactions. It fills the gap left by the deprecated react-addons-perf module, suggesting where shouldComponentUpdate could help.
Use cases
- find unnecessary re-renders in a react app
- identify components that need shouldComponentUpdate
- audit react component performance from the command line
- replace deprecated react-addons-perf
- profile react app rendering during click and input events
When to choose
- you maintain a legacy React app (pre-16 era) and want a quick re-render audit
- you prefer a CLI-driven interactive profiling session over browser devtools
When to avoid
- you need actively maintained tooling - last release was 2018
- you use React 16+ where React DevTools Profiler covers this
- you need React Native support, which was never shipped
