API First Development

Design

API First is a development approach where the API design comes before implementation. This strategy ensures that the API meets the needs of all consumers before any code is written.

Key Principles
  • 1Design the API before implementing it
  • 2Use API description formats like OpenAPI/Swagger
  • 3Get feedback on the API design early
  • 4Treat APIs as products with their own lifecycle
Benefits
  • 1Enables parallel development of frontend and backend
  • 2Improves API consistency and usability
  • 3Reduces development time and costs
  • 4Facilitates better documentation and testing
