Upgrades React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json dependencies, migrating native iOS and Android configuration, resolving CocoaPods and Gradle changes, and handling breaking API updates. Use when upgrading React Native, bumping RN version, updating from RN 0.x to 0.y, or migrating Expo SDK alongside a React Native upgrade.

1 rule. 1 is common, 0 are distinctive, and 0 are very specific to this project.

    Common

    Most of the 5 edited versions we read keep these.

    Distinctive

    This author's own choices. Worth a look.

    Very specific

    Tied to their project's names, files or tools. Probably skip.

    Verify: Run post-upgrade checks via [upgrade-verification.md][upgrade-verification]

    line 23

“Common” is measured: kept by at least 6 in 10 of the 5 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Upgrading React Native

Overview

Covers the full React Native upgrade workflow: template diffs via Upgrade Helper, dependency updates, Expo SDK steps, and common pitfalls.

Typical Upgrade Sequence

  1. Route: Choose the right upgrade path via upgrading-react-native.md
  2. Diff: Fetch the canonical template diff using Upgrade Helper via upgrade-helper-core.md
  3. Dependencies: Assess and update third-party packages via upgrading-dependencies.md
  4. React: Align React version if upgraded via react.md
  5. Expo (if applicable): Apply Expo SDK layer via expo-sdk-upgrade.md
  6. Verify: Run post-upgrade checks via upgrade-verification.md
# Quick start: detect current version and fetch diff
npm pkg get dependencies.react-native --prefix "$APP_DIR"
npm view react-native dist-tags.latest

# Example: upgrading from 0.76.9 to 0.78.2
# 1. Fetch the template diff
curl -L -f -o /tmp/rn-diff.diff \
  "https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/0.76.9..0.78.2.diff" \
  && echo "Diff downloaded OK" || echo "ERROR: diff not found, check versions"
# 2. Review changed files
grep -n "^diff --git" /tmp/rn-diff.diff
# 3. Update package.json, apply native changes, then install + rebuild
npm install --prefix "$APP_DIR"
cd "$APP_DIR/ios" && pod install
# 4. Validate: both platforms must build successfully
npx react-native build-android --mode debug --no-packager
xcodebuild -workspace "$APP_DIR/ios/App.xcworkspace" -scheme App -sdk iphonesimulator build

When to Apply

Reference these guidelines when:

  • Moving a React Native app to a newer version
  • Reconciling native config changes from Upgrade Helper
  • Validating release notes for breaking changes

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
