README.md

The error code system substitutes React's error messages with error IDs to provide a better debugging support in production. Check out the blog post here.

  • codes.json contains the mapping from IDs to error messages. This file is generated by the Gulp plugin and is used by both the Babel plugin and the error decoder page in our documentation. This file is append-only, which means an existing code in the file will never be changed/removed.
  • extract-errors.js is an node script that traverses our codebase and updates codes.json. You can test it by running yarn extract-errors.
  • transform-error-messages is a Babel pass that rewrites error messages to IDs for a production (minified) build.
