Troubleshooting

"Command not found: create-core-stack"

Make sure npx is working:

npx --version

Try with explicit version:

npx create-core-stack@latest my-app

"EACCES: permission denied"

Don't use sudo with npx. If you get permission errors:

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH

Generated project TypeScript errors

Make sure you're using Node.js >= 18:

node --version

Docker issues

Ensure Docker is running:

docker --version
docker ps

FAQ

Q: What's the difference between presets? A: Minimal has basic features, Full-Featured has everything, Analytics-Focused has Adjust + Scate.

Q: Can I add features later? A: Yes, but it's easier to start with more features and remove what you don't need.

Q: Is this production-ready? A: The generated code is production-quality, but this is a beta tool (v0.1.0). Test thoroughly.

Q: What about web support? A: The mobile app is React Native (mobile-only). For web, consider using Expo's web support or a separate web app.

Q: Can I customize the templates? A: Not yet, but template customization is planned for future versions.

Roadmap

• [ ] v0.3.0: More SDK integrations (Firebase, Supabase)
