React introduced the experimental "error boundaries" feature in version 15. Components define an
unstable_handleError
method to opt into this feature. Version 16 finalizes support for error boundaries, but with a new name-componentDidCatch
.I ran a codemod to rename all identifiers in the React codebase. I also searched-and-replaced strings occurrences (eg test case names).
Relates to the "make error boundaries official" beta-blocker in #8854
