It currently runs when you run `npx expo start` in a project with `tsconfig.json` or any TypeScript file in the project. - This change will run the TypeScript check continuously until TypeScript is setup. This only applies to projects using Metro, and currently is only run in `npx expo start`, and the run commands (when the server is started in the current window, e.g. not headless mode). <!-- Please describe the motivation for this PR, and link to relevant GitHub issues, forums posts, or feature requests. --> # How - Fork the `runServer` function from Metro into the CLI so we can access the Metro bundler instance directly. - Use Metro's native file watching to observe new TypeScript files being added to the project (within the observable files). This is fast and ensures we don't accidentally block a thread that otherwise could've been used for bundling. - The TypeScript continuous check only runs once, if you remove TypeScript and add it back in the same process, then nothing happens. This is a performance optimization. - If TypeScript is enabled while the process is running, the user will not be prompted to install, the packages will just install in the project. Failures will be displayed in the running process, and no more attempts will be made. - If TypeScript is detected on start then the existing system will be used and the continuous check will be skipped, this means projects already using TypeScript won't have any technical performance hit. <!-- How did you build this feature or fix this bug and why? --> # Test Plan - In a project without TypeScript: - `npx expo` - `touch tsconfig.json` or `mv index.js index.tsx` or `touch foo.tsx` - TypeScript is automatically installed for the project. - `EXPO_NO_TYPESCRIPT_SETUP` voids this behavior - Added unit tests. <!-- Please describe how you tested this change and how a reviewer could reproduce your test, especially if this PR does not include automated tests! If possible, please also provide terminal output and/or screenshots demonstrating your test/reproduction. --> # Checklist <!-- Please check the appropriate items below if they apply to your diff.
