Upgrading React Native

What it does

When your agent uses it

• Upgrading React Native
• Bumping RN version
• Updating from RN 0.x to 0.y
• Migrating Expo SDK alongside a React Native upgrade

Example prompts

• “Use the upgrading-react-native skill to upgrade React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json…”
• “/upgrading-react-native”

Requirements

• Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Route: Choose the right upgrade path via upgrading-react-native.md
2. 2Diff: Fetch the canonical template diff using Upgrade Helper via upgrade-helper-core.md
3. 3Dependencies: Assess and update third-party packages via upgrading-dependencies.md
4. 4React: Align React version if upgraded via react.md
5. 5Expo (if applicable): Apply Expo SDK layer via expo-sdk-upgrade.md
6. 6Verify: Run post-upgrade checks via upgrade-verification.md

What it can do on your machine

Read from SKILL.md and the folder at commit 61e6e7d. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm
  • curl
  • npx
  • xcodebuild

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • raw.githubusercontent.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Upgrading React Native loads about 1.1k tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 230 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~102

When it runs · the whole SKILL.md, loaded when a task matches

~1.1k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~5.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

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.

# 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
