Difficulty:MediumTopic:Documentation

API documentation is commonly generated using swagger-ui-express alongside swagger-jsdoc to expose auto-generated API specs directly at endpoints like /api-docs.

Key Takeaways
  • Annotate route handlers with JSDoc YAML comments.
  • Expose dynamic, interactive Swagger UI documentation endpoints for frontend consumers.
