Express.js Skill

When to Use

  • •Building REST APIs
  • •Composing middleware stacks
  • •Handling HTTP requests/responses

Critical Patterns

  • •Use Router for modular routes
  • •Centralized error handling middleware
  • •Async/await in route handlers

Decision Tree

  • •API versioning? → Use Router
  • •Auth needed? → Use middleware
  • •Error handling? → Use error middleware

Edge Cases

  • •Async error propagation
  • •Middleware order bugs
  • •Large payload handling
