Bump react-scripts from 2.1.1 to 3.0.0

[dependabot-preview]

Bumps react-scripts from 2.1.1 to 3.0.0.

Changelog

Sourced from react-scripts's changelog.

3.0.0 (April 22, 2019)

Create React App 3.0 brings some exciting new features including support for Hooks!

Thanks to all the maintainers and contributors who worked so hard on this release! 🎉

Highlights

• Jest 24: #6278
• Hooks support: #5997
• TypeScript linting: #6513
• browserslist support in @babel/preset-env: #6608
• Absolute imports using jsconfig.json/tsconfig.json: #6656

Migrating from 2.1.x to 3.0.0

Inside any created project that has not been ejected, run:

npm install --save --save-exact react-scripts@3.0.0

or

yarn add --exact react-scripts@3.0.0

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

Breaking Changes

Like any major release, react-scripts@3.0.0 contains a few breaking changes. We expect that they won't affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

Jest 24

We've updated from Jest 23 to get the latest improvements in Jest 24. We've noticed some differences in snapshot serialization in Jest 24, so you may need to adjust your tests slightly once you update. You can read more about what's changed in the Jest 24 blog post.

Hooks support

We now enforce Rules of Hooks with eslint-plugin-react-hooks. If you are breaking any of the rules of Hooks this will cause your build to fail.

TypeScript linting

We now lint TypeScript files. You can see the list of rules we enforce to check if your project is compatible. If you're using Visual Studio Code you can follow our guide to setup up your editor to display lint warnings.

browserslist support in @babel/preset-env

The browserslist config in your package.json is now used to control the output of your JavaScript files. You can use separate configuration for development and production. See here for a good starting point which gives a good development experience, especially when using language features such as async/await, but still provides high compatibility with many browsers in production
