SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Setting up a Node.js backend from scratch involves repetitive decisions about middleware ordering, authentication, error handling, and database wiring. This Skill provides working Express.js patterns so you can assemble a REST API without re-deriving boilerplate each time. ## Core Features & Use Cases - Middleware Chains: Implement logging, JWT token verification, and async error-catching wrappers that compose cleanly across routes. - RESTful CRUD Routes: Build paginated GET, POST, PATCH, and DELETE endpoints with authentication guards and consistent response shapes. - Database & Auth Integration: Connect PostgreSQL via Sequelize models and issue JWT tokens with bcrypt password hashing. - Use Case: You need a users API with login, protected routes, and centralized error handling. Apply the reference guides to scaffold the router, authentication middleware, and Sequelize model in one pass. ## Quick Start Ask the AI to create an Express REST API with JWT authentication, CRUD routes for users, and centralized error handling using this Skill.

FAQPage Schema
How do I build a REST API with Express.js?

Create an Express app, add express.json() middleware, and define routers for each resource with GET, POST, PATCH, and DELETE handlers. Mount routers with app.use and finish with centralized error-handling and 404 middleware.

How to implement JWT authentication in Express middleware?

Extract the Bearer token from the Authorization header, verify it with jwt.verify against your secret, and attach the decoded user to req.user before calling next(). Return 401 for missing tokens and 403 for invalid ones.

Does Express work with PostgreSQL databases?

Yes, Express connects to PostgreSQL through the Sequelize ORM. Define models with DataTypes, configure the connection with host and dialect options, and call sequelize.sync to align the schema.

Why do async Express route errors crash my server?

Express does not catch rejected promises from async handlers automatically. Wrap handlers in an asyncHandler utility that forwards errors to next(), so your error-handling middleware receives them.

What are the limitations of JWT-based authentication?

JWTs cannot be revoked individually before expiry, so short expiration windows are needed for sensitive actions. Tokens must be stored securely on the client and secrets kept in environment variables, never in code.
