Install upgrading-react-native

In a terminal with Node.js, npm and Git, run the command for your agent. The Skills CLI installs the complete package directory, including referenced files within it. Review its install prompt, then start a new agent session. A skill package does not set up an MCP server connection.

Claude Code

.claude/skills/upgrading-react-native/SKILL.md

Project skills are committed with the repo. Use the user directory for a personal install across every project.

Project install

npx skills add 'https://github.com/callstackincubator/agent-skills/tree/main/skills/upgrading-react-native' --skill 'upgrading-react-native' --agent 'claude-code'
Install for all projects instead

Personal install

npx skills add 'https://github.com/callstackincubator/agent-skills/tree/main/skills/upgrading-react-native' --skill 'upgrading-react-native' --agent 'claude-code' --global

Codex

.agents/skills/upgrading-react-native/SKILL.md

Codex reads `.agents/skills/` as its primary location, which is also the cross-platform default other clients honour.

Project install

npx skills add 'https://github.com/callstackincubator/agent-skills/tree/main/skills/upgrading-react-native' --skill 'upgrading-react-native' --agent 'codex'

Cursor

.agents/skills/upgrading-react-native/SKILL.md

Cursor also loads `.agents/skills/`, `.claude/skills/`, and `.codex/skills/`, so one committed copy can serve several clients.

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

# 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
