Capacitor App Upgrade v4 to v5
Upgrade a Capacitor app from version 4 to version 5.
When to Use This Skill
- User says the app is on Capacitor 4 and must move to v5
- User wants the exact v4 to v5 migration path
- User needs v5-specific native and package updates
Live Project Snapshot
Current Capacitor packages from package.json:
!node -e "const fs=require('fs');if(!fs.existsSync('package.json'))process.exit(0);const pkg=JSON.parse(fs.readFileSync('package.json','utf8'));const out=[];for(const section of ['dependencies','devDependencies']){for(const [name,version] of Object.entries(pkg[section]||{})){if(name.startsWith('@capacitor/'))out.push(section+'.'+name+'='+version)}}console.log(out.sort().join('\n'))"
Procedure
- Start from the injected package snapshot and confirm the current
@capacitor/core version.
- Update all
@capacitor/* packages to the v5-compatible range.
- Review the v4 to v5 migration notes before editing native files.
- Run
npm install.
- Sync with
npx cap sync.
- Verify the iOS and Android builds.
Error Handling
- If the automated migration misses a package, update it manually before syncing again.
- If iOS fails, check the deployment target and Xcode compatibility for Capacitor 5.
- If Android fails, check the Gradle and Java requirements for Capacitor 5.
