Versioning

NOTE: version 2.X (io.swagger) and 3.X (io.swagger.codegen.v3) have different group ids.

2.X and 3.X version lines of Swagger Codegen are available; 2.X (master branch) supports Swagger/OpenAPI version 2, while 3.X (3.0.0 branch) supports OpenAPI version 3 (and version 2 via spec conversion to version 3). Online generator of version 3.X supports both generation from Swagger/OpenAPI version 2 (by using engine + generators of 2.X) and version 3 specifications.

NOTE: this document refers to version 2.X, check here for 3.X.

Swagger Codegen 2.X (master branch)

Swagger Codegen 2.X supports Swagger/OpenAPI version 2.

Overview

This is the Swagger Codegen project, which allows generation of API client libraries (SDK generation), server stubs and documentation automatically given an OpenAPI Spec. Currently, the following languages/frameworks are supported:

• API clients: ActionScript, Ada, Apex, Bash, C# (.net 2.0, 3.5 or later), C++ (cpprest, Qt5, Tizen), Clojure, Dart, Elixir, Elm, Eiffel, Erlang, Go, Groovy, Haskell (http-client, Servant), Java (Jersey1.x, Jersey2.x, OkHttp, Retrofit1.x, Retrofit2.x, Feign, RestTemplate, RESTEasy, Vertx, Google API Client Library for Java, Rest-assured), Kotlin, Lua, Node.js (ES5, ES6, AngularJS with Google Closure Compiler annotations) Objective-C, Perl, PHP, PowerShell, Python, R, Ruby, Rust (rust, rust-server), Scala (akka, http4s, swagger-async-httpclient), Swift (2.x, 3.x, 4.x, 5.x), Typescript (Angular1.x, Angular2.x, Fetch, jQuery, Node)
• Server stubs: Ada, C# (ASP.NET Core, NancyFx), C++ (Pistache, Restbed), Erlang, Go, Haskell (Servant), Java (MSF4J, Spring, Undertow, JAX-RS: CDI, CXF, Inflector, RestEasy, Play Framework, PKMST), Kotlin, PHP (Lumen, Slim, Silex, Symfony, Zend Expressive), Python (Flask), NodeJS, Ruby (Sinatra, Rails5), Rust (rust-server), Scala (Finch, Lagom, Scalatra)
• API documentation generators: HTML, Confluence Wiki
• Configuration files: Apache2
• Others: JMeter
