OpenAPI v3 code generator for Go

Intro

No reflection

  • The json encoding is code-generated, optimized and uses jx for speed and overcoming encoding/json limitations
  • Validation is code-generated according to specification

No boilerplate

  • Structures are generated from OpenAPI v3 specification
  • Arguments, headers, url queries are parsed according to specification into structures
  • String formats like uuid, date, date-time, uri are represented by go types directly
  • Sum types are generated for OneOf, with discriminator or implicit type inference
  • Optional and nullable are supported without pointers if possible

OpenTelemetry
