Choosing a Template

Common Files

All templates share common files. Load the bankr-client-patterns skill for:

• bankr-client.ts - Complete API client
• package.json - Base dependencies
• tsconfig.json - TypeScript config
• .env.example - Environment template
• .gitignore - Standard ignores

Next Steps After Scaffolding

1. Install dependencies: bun install or npm install
2. Configure API key: Copy .env.example to .env and add BANKR_API_KEY
3. Customize: Modify the template for your use case
4. Run: bun dev or npm run dev for development
5. Build: bun run build or npm run build for production
