RC Patches

info

Documents in this section go over steps to run different types of React Native release updates. Its intended audience is those in relevant release roles.

Pre-requisites​

  • You have some pick requests that qualify for a new Release Candidate (RC) patch in the "road to 0.XX.0" discussion.
  • Write access to react-native repository.
  • Write access to releases repository.
  • One CircleCI personal API token - see here how to set one.

1. Check out the latest version from release branch​

# Be on relevant release branch
# update the stable branch with tags
git pull origin <release-branch> --tags
git checkout -b <release-branch>

# cherry pick relevant commits
git cherry-pick <commit-hash>

2. Bump monorepo packages​

Update all packages in the monorepo that were modified by the cherry picks. You can do it by running:

yarn bump-all-updated-packages # All the package bumps should be on the patch level
git push origin 0.XX-stable

After pushing, the CI will take care to publish the new packages automatically.

3. Test the current changes​

Before continuing further, follow the testing guide to ensure the source code doesn't have any major issues.

info

Since testing is a time consuming activity (>1 hrs) it is recommended that the release crew coordinates on the steps above then do testing on at least two separate systems in an async way.

4. Run trigger-react-native-release script​

# once verified all the cherry-picked commits, we can push them to remote
git push

# run a script to bump the version
# You **do not** want this release marked as "latest"!
yarn trigger-react-native-release --to-version 0.y.0-rc.x --token <YOUR_CIRCLE_CI_TOKEN>

5. Watch CircleCI to ensure right jobs are being triggered​

  • Once you have run the bump script script, head to CircleCI and you should see under the releases workflow, a prepare-package-for-release job.

  • Once complete you should be able to run npm view react-native and verify that under the next tag, the version is the expected release version.

    npm view react-native
    ...
    dist-tags:
    latest: 0.(y-1).1            next: 0.y.0-rc.x         nightly: 0.0.0-f617e022c

6. Create a GitHub Release​

  • Create a GitHub Release with this template and check "Pre-Release" checkbox.
- <!-- TODO List out notable picks for this patch -->

---

To test it, run:

<!-- TODO Update with your version -->

npx react-native init RN069RC0 --version 0.69.0-rc.0

- You can participate in the conversation on the status of this release in the [working group](https://github.com/reactwg/react-native-releases/discussions).

- To help you upgrade to this version, you can use the [upgrade helper](https://react-native-community.github.io/upgrade-helper/) ⚛️

- See changes from this release in the [changelog PR](https://github.com/facebook/react-native/labels/%F0%9F%93%9D%20Changelog)

### Help us testing 🧪

<!-- TODO Add the call to action for something specific that we want folks to test -->

Let us know how it went by posting a comment in the [working group discussion](https://github.com/reactwg/react-native-releases/discussions)! Please specify with system you tried it on (ex. macos, windows).

**Bonus points:** It would be even better if you could swap things around: instead of using a fresh new app, use a more complex one - or use a different library that is already leveraging the new architecture!

7. Update the relevant discussion post with the latest RC​

Go back to the "road to 0.XX.0" discussion and update the "Current release candidate" line with the new version you published.

8. Broadcast that release candidate is out​

Once all the steps above have been completed, it's time to signal to the community that the new RC is available for testing! Do so in the following channels:
