Roadmap for version 3.3.0

We are planning to release Create React App version 3.3.0 soon.

Planned Features

• Templates: https://github.com/facebook/create-react-app/pull/7716
• Optional Chaining and Nullish Coalescing: https://github.com/facebook/create-react-app/pull/7438

Refer to the 3.3.0 Milestone to see exactly what is included in this release.

☢️ How Can I Test This Now? ☢️

We’re happy you’d like to test the next version of react-scripts! Before getting into the details, we’d like to make you aware of a few things:

1. Features may be broken or not work as expected
2. There will be more breaking changes introduced before the final release ⚠️
3. Documentation for new features is still sparse, so look through the pull requests or the documentation on master for how they’re expected to work

You can install the latest beta version of react-scripts using one of the following commands:

$ # Create a new application
$ # JavaScript
$ npx create-react-app@next --scripts-version=@next --template=cra-template@next app-name
$ # TypeScript
$ npx create-react-app@next --scripts-version=@next --template=typescript@next app-name
$ # Upgrade an existing application
$ yarn upgrade react-scripts@3.3.0-next.62

Known Issues in 3.3.0 Betas

• ESLint no-restricted-globals rule: false positive with optional chaining: https://github.com/typescript-eslint/typescript-eslint/issues/1090
• If you’ve used our experimental feature to extend ESLint you may be affected by other rules in typescript-eslint that don’t yet support optional chaining: https://github.com/typescript-eslint/typescript-eslint/issues/1051

Please report any bugs you encounter or behavior you believe to be incorrect by creating a new issue. Have fun!

Actually TypeScript 3.7 and the required changes in typscript-eslint and Prettier were blocking the release. I believe the final typescript-eslint fixes have been published so we’re hoping to release 3.3.0 in the next couple of days.

typscript-eslint and Prettier now officially support TS 3.7, right? Any further blockers to release CRA 3.3 (maybe just with TS 3.7 support and deferring all the unfinished stuff)?
