Ask HN: How to performance test React webapps for rendering speed regressions?
2 by janci5243 | 2 comments on Hacker News.
As React webapps get large and start to contain a lot of complex components, they often do not perform well and manifest low FPS in browser. As a result, engineers add strategies such as memoization (React.memo, shouldComponentUpdate) to avoid unnecessary computation, however they logic is fragile to code changes. Is there a way to automatically test performance (maybe in terms of FPS) of React applications regularly in CI pipelines? Any tools for this out there?
