The current allowlist for capitalized function identifiers only allows stdlib JS modules. This PR introduces a new compiler option to allow passing in a set of allowed capitalized user function identifiers. It's a hack (in the absence of a type system) to let us check that capitalized function calls are only possible for identifiers that aren't bound to a React component. I considered adding a mechanism in fixtures to configure compiler options per-fixture, but opted to keep it simple for now and special case a `ReactForgetSecretInternals` identifier as one allowed user function in transform tests.
React Forget
React Forget is an experimental Babel plugin to automatically memoize React Hooks and Components.
Development
# tsc --watch
$ yarn dev
# in another terminal window
$ yarn test --watch
Notes
An overview of the implementation can be found in the Architecture Overview.
This transform
- needs plugin-syntax-jsx as a dependency to inherit the syntax from.
- should be run before plugin-transform-react-jsx
- assume the enforcement of rules of hooks, i.e.
- only call hooks from React functions
- only call hooks at the top level
