We appreciate you spending the time to work on these changes. Please
provide enough information so that others can review your pull request.
The three fields below are mandatory.
Before submitting a pull request, please make sure the following is
done:
1. Fork [the repository](https://github.com/facebook/react) and create
your branch from `main`.
2. Run `yarn` in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch
TestName` is helpful in development.
5. Run `yarn test --prod` to test in the production environment. It
supports the same options as `yarn test`.
6. If you need a debugger, run `yarn test --debug --watch TestName`,
open `chrome://inspect`, and press "Inspect".
7. Format your code with
[prettier](https://github.com/prettier/prettier) (`yarn prettier`).
8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only
check changed files.

## Summary
Updated the UI of the React compiler playground. The config, Input, and
Output panels will now span the viewport width when "Show Internals" is
not toggled on. When "Show Internals" is toggled on, the old vertical
accordion tabs are still used. Going to add support for the "Applied
Configs" tabs underneath the "Config Overrides" tab next.

Currently in the `compiler` workspace, we invoke esbuild directly to
build most packages (with the exception of `snap`). This has been mostly
fine, but does not allow us to do things like generate type declaration
files.
I would like #32416 to be able to consume the merged
eslint-plugin-react-compiler from source rather than via npm, and one of
the things that has come up from my exploration in that stack using the
compiler from source is that babel-plugin-react-compiler is missing type
declarations. This is primarily because React's build process uses
rollup + rollup-plugin-typescript, which runs tsc. So the merged plugin
needs to typecheck properly in order to build. An alternative might be
to migrate to something like babel with rollup instead to simply strip
types rather than typecheck before building. The minor downside of that
approach is that we would need to manually maintain a d.ts file for
eslint-plugin-react-hooks. For now I would like to see if this PR helps
us make progress rather than go for the slightly worse alternative.
[`tsup`](https://github.com/egoist/tsup) is esbuild based so build
performance is comparable. It is slower when generating d.ts files, but
it's still much faster than rollup which we used prior to esbuild. For
now, I have turned off `dts` by default, and it is only passed when
publishing on npm.
If you want to also generate d.ts files you can run `yarn build --dts`.

I still need to test if this unblocks #32416 but this stack can be
landed independently though as we could probably just release type
declarations on npm. No one should be using the compiler directly, but
if they really wanted to, lack of type declarations would not stop them
(cf React secret internals).
Note that I still kept esbuild as we still use it directly for forgive.

Our e2e setup with monaco is kinda brittle since it relies on the dom.
It seems like longish text gets truncated so let's just simpify all
these test cases.

Currently the playground is setup as a linked workspace for the
compiler which complicates our yarn workspace setup and means that snap
can sometimes pull in a different version of react than was otherwise
specified.
There's no real reason to have these workspaces combined so let's split
them up.

Pull Request resolved: https://github.com/facebook/react/pull/31081
Updates the prettier config to format all `.ts` and `.tsx` files in the
repo using the existing defaults and removing overrides.
The first commit in this PR contains the config changes, the second is
just the result of running `yarn prettier-all`.
