Rules

• Paths
  • Operation IDs are required.

  API users can refer to concrete resources by a using specific IDs, useful when generating code automatically from the final Swagger JSON file.

  • Operation IDs must start with the request method.

  Allows categorizing operations by the request method being used, similar convention to what gRPC recommends.

  • Operation IDs should describe the resource. Not enforced

  Allows matching the named resource with the final operation ID. For example: GET /blogs/{id}/comments could be named as getBlogsComment.

  • At least one tag should be defined.

  Allows categorizing similar resources.

• Parameters
  • Models for Body requests must be named as <operationID>Request.

  Allows matching the request with the operationID, similar convention to what gRPC recommends. For example: PostBlogsRequest

  • Query values must be lowercase and snake_case.

  Self explanatory.

• Responses (for 2XX status codes only)
  • Response models must be named as <operationID>Response

  Allows matching the response with the operationID, similar convention to what gRPC recommends. For example: GetBlogsResponse.

  • Arrays are not encouraged, instead using a new model that follows the rules defined above is preferred.

  To keep the naming consistent accross the board.
