OpenAPI Code Generation

Code generator that ingest a OpenAPI Specification and writes the structs that represent resources of that given specification and also builds the client based on the paths.

Currently supports two types of generation:

• Tesla - Generates a module with a Tesla client.
• Req - Generates a module using Req.

By default we're using Jason for encoding and decoding of structs

Does not require you to install extra dependencies as we're using

Roadmap

• Support YAML specification parsing
• Support Inheritance and Polymorphism
• Add typespecs to generated Structs
• Add typespecs to Client
• Generate tests for Client

Installation

Install it using:

mix do local.rebar --force, local.hex --force
mix escript.install hex openapi_codegen

Usage

Generating a Tesla client using PetStore example:

openapi_codegen --tesla --output-path lib openapi_petstore.json

Generating a Req client using PetStore example:

openapi_codegen --req --output-path lib openapi_petstore.json

This examples will generate your code in your folder lib and also create a lib/components with all the structs.
