Releasing Create React Native App

This document contains checklists to be done before releasing new versions.

WARNING: Just don't release create-react-native-app. Just don't do it.

The rest of these instructions are for releasing react-native-scripts.

Update Dependency Versions

This section only applies when bumping the Expo SDK and React Native versions.

  • react-native
  • react
  • expo
  • jest-expo
  • react-test-renderer
  • app.json:expo.sdkVersion

Also, update VERSIONS.md.

Verify .flowconfig is up to date after updating expo-sdk

After upgrading the expo-sdk version (which transitively updates the react-native version), ensure that the .flowconfig template is up to date.

Easiest way to do this, is:

  1. Use this handy chart to find out the underlying react-native versions of the old and new expo-sdk.
  2. Get react-native .flowconfig changeset in the React Native repo with git diff tags/v0.41.0 tags/v0.42.0 -- local-cli/templates/HelloWorld/_flowconfig
  3. If there are changes, land diff to CRNA .flowconfig template
  4. To test, follow instructions in README/Adding Flow on a freshly generated project, and do npm run flow to ensure the process exits without error.
  5. If there are new issues with third-party dependencies, fix them upstream or add necessary [ignore] fields to .flowconfig.

Clean, Build, Pack, Test, Publish

Run yarn run build && npm pack in the scripts package to get a tarball. Test this tarball with a clean yarn cache on Mac and Windows at a minimum. If everything checks out, run yarn run publish after bumping the version in package.json.
