This PR attempts to add typechecking to the server actions tests fixtures in order to add an extra layer of validation against compiler bugs. (there's a couple!). Unfortunately the tests were pretty loosey-goosey around undefined variables, so there's a lot of noise in adding missing imports for `Button` etc. i tried to call out the interesting changes via PR comments. Note that this is a bit limited, because we often have to rely on typescript inferring some sensible types for the outputs -- see e.g. the issue with `24/output.js` mentioned below. In case typescript can't infer sensible types for something, we can just exclude that file from checking. this seems to be pretty rare, so i think it's okay. We should also definitely add typechecking to the other fixture folders, but this PR is already big, so i want to do that piecemeal. ### TODO - [x] invoke the typechecker in CI - added a `check-compiler-fixtures` script that runs as part of `types-and-precompiled` (open to feedback, maybe this isn't the right place?) - [x] figure out how to make `tsc` error on `crates/next-custom-transforms/tests/fixture/server-actions/server-graph/51/output.js`, where we're referencing a non-existent variable `$$RSC_SERVER_ACTION_0`. right now, it emits no errors - this is a compiler bug, and i want to catch bugs like this in the future - solution: https://github.com/vercel/next.js/pull/75944 - [x] figure out why `tsc` is complaining about a type mismatch in `crates/next-custom-transforms/tests/fixture/server-actions/server-graph/24/output.js` - we can work around this by loosening the types for `registerServerReference`, but i'd rather we didn't have to do that - this seems to be a bizarre TS behavior where `fn.bind(...)` makes all the params optional in JS files. ignoring this for now
