Typescript: Simplified typescript steps not working

Is this a bug report?

Yes

Did you try recovering your dependencies?

Yes

Environment

Environment: OS: macOS 10.14 Node: 10.12.0 Yarn: 1.10.1 npm: 6.4.1

Packages: (wanted => installed) react: ^16.5.2 => 16.5.2 react-dom: ^16.5.2 => 16.5.2 react-scripts: 2.0.5 => 2.0.5

Steps to Reproduce

I noticed that typescript was added to the project officially. I went ahead and created a new project and followed in the instructions detailed in https://github.com/facebook/create-react-app/commit/3c11efe206d7ffe1ea75ebf32aa207ddfd8c0499 but they did not work. I’ve walked back through the commit history and tried some of the previously detailed steps to no avail. Neither creating a tsconfig.json or a tsconfig.json with {} in the file worked for me either.

Followed instructions listed at https://github.com/facebook/create-react-app/blob/master/docusaurus/docs/adding-typescript.md

1. npx create-react-app <app>
2. yarn add typescript @types/react @types/react-dom @types/jest
3. Rename src/index.js to src/index.tsx

Expected Behavior

I expected the app to start correctly

Actual Behavior

Received an error .

Could not find a required file.
  Name: index.js

Please use this new method instead of yarn link:

npx create-react-app@next app-name --scripts-version=2.0.6-next.c662dfb0 --typescript

For existing projects, run yarn unlink react-scripts and install yarn add react-scripts@2.0.6-next.c662dfb0.

Let me know if that works for you!

@sebasmurphy you can close this 😃

I assumed it had already been done given all of the recent commits to master in /packages/react-scripts

Things that land in master might not get released for weeks or even months (in the worst case). When things get released, they appear in the changelog and on the releases page. 😉
