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][upgrading-react-native]
2. Diff: Fetch the canonical template diff using Upgrade Helper via [upgrade-helper-core.md][upgrade-helper-core]
3. Dependencies: Assess and update third-party packages via [upgrading-dependencies.md][upgrading-dependencies]
4. React: Align React version if upgraded via [react.md][react]
5. Expo (if applicable): Apply Expo SDK layer via [expo-sdk-upgrade.md][expo-sdk-upgrade]
6. Verify: Run post-upgrade checks via [upgrade-verification.md][upgrade-verification]

# Quick start: detect current version and fetch diff
npm pkg get dependencies.react-native --prefix "$APP_DIR"
npm view react-native dist-tags.latest
