Building efficient, reliable, and secure REST APIs involves following several best practices. Here's a detailed breakdown of these practices, including versioning, security, and optimization techniques for your NestJS-based microservice:

1. API Design & Structure

• Resource Naming: Use meaningful, clear, and consistent names for your endpoints (e.g., /movies, /movies/{id}). Prefer nouns for resources and use HTTP methods to represent actions (GET, POST, PUT, DELETE).

  • POST for creating resources.
  • PUT or PATCH for updating resources.
  • DELETE for removing resources.
• Use HTTP Status Codes: Return appropriate status codes (e.g., 200 for success, 201 for created, 404 for not found, 400 for bad request, 500 for server errors).
