How to Vibe Code a REST API
Quick Answer
Vibe coding a REST API is efficient with Cursor or Replit. Describe your endpoints, data models, and authentication requirements, and the AI generates the entire API with route handlers, validation, and database integration.
Define your API endpoints
List all the endpoints you need — CRUD operations, authentication routes, and any custom business logic endpoints.
Choose your framework
Prompt the AI to use Express.js, Fastify, Hono, or Next.js API routes based on your preference.
Generate route handlers
Let the AI create route handlers with request validation, error handling, and response formatting.
Add database integration
Connect to PostgreSQL, MongoDB, or Supabase for data persistence. Generate database schemas and migration files.
Add authentication
Implement JWT tokens, API keys, or OAuth for securing your endpoints.
Test and document
Generate API tests and OpenAPI/Swagger documentation for your endpoints.
