OpenAPI Specification (formerly Swagger Specification) is an API description format for REST APIs. An OpenAPI file allows you to describe your entire API, including:
- Available endpoints (
/users) and operations on each endpoint (
- Operation parameters Input and output for each operation
- Authentication methods
API specifications can be written in YAML or JSON. The format is easy to learn and readable to both humans and machines. The complete OpenAPI Specification can be found on GitHub: OpenAPI 3.0 Specification
- A Standalone HTTP Server
- An Express Router for easy mounting to any existing Express HTTP Server.
npm install wechaty-openapi
export WECHATY_PUPPET_SERVICE_TOKEN=__YOUR_TOKEN__wechaty-openapi-server \ --mountpoint /api --port 8080
Then visit http://localhost:8080/api
Thanks to the ecosystem of gRPC, we can generate OpenAPI Specification from our gRPC proto definitions automatically.
We are using gRPC to JSON proxy generator following the gRPC HTTP spec as the OpenAPI Specification generator (protoc-gen-openapiv2), and using Like grpc-gateway, but written in node and dynamic project to serve an HTTP RESTful API to gRPC proxy.

Swagger is a set of open-source tools built around the OpenAPI Specification that can help you design, build, document, and consume REST APIs. The major Swagger tools include:
- Swagger Editor – browser-based editor where you can write OpenAPI specs.
- Swagger UI – renders OpenAPI specs as interactive API documentation.
- Swagger Codegen – generates server stubs and client libraries from an OpenAPI spec.
The ability of APIs to describe their structure is the root of all awesomeness in OpenAPI. Once written, an OpenAPI specification and Swagger tools can drive your API development further in various ways:
- Design-first users: use Swagger Codegen to generate a server stub for your API. Then, the only thing left is implementing the server logic – and your API is ready to go live!
- Use Swagger Codegen to generate client libraries for your API in over 40 languages.
- Use Swagger UI to generate interactive API documentation that lets your users try out the API calls directly in the browser.
- Use the spec to connect API-related tools to your API. For example, import the spec to SoapUI to create automated tests for your API.
- And more! Check out the open-source and commercial tools that integrate with Swagger.
If you're an API provider and want to use Swagger tools to build your APIs and the OpenAPI specification to describe your APIs - there are several approaches available:
- Use the Swagger Editor to create your OAS definition and then use Swagger Codegen to generate server implementation.
- Use the Swagger UI to visualize and document your OAS definition
- Design, document, and develop APIs as a team using SwaggerHub
Finding an easy way to generate the OpenAPI definition from an existing API can be challenging. First, you have to reverse engineer the API and get acquainted with the process of developing the OAS from existing APIs. The good news is that Swagger tools can help you do this with ease.
- Use Swagger Core open source project to create the OAS from your existing Java APIs. Swagger Core supports frameworks like JAX-RS or node.js.
Have a look at this example to see how Swagger Core can help your JAX-RS implemented API - https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-JAX-RS-Project-Setup-1.5.X
- Swagger Inspector allows you to easily and quickly auto-generate an OAS definition from any API endpoint right from your browser
If, on the other hand, you're an API Consumer who wants to integrate with an API that has an OpenAPI definition, you can use Swagger Inspector or the online version of Swagger UI to explore the API (given that you have a URL to the APIs Swagger definition) - and then use Swagger Codegen to generate the client library of your choice. In either case - be sure to check out the long list of open source projects and our commercial offering, SwaggerHub.

OpenAPI 3.0 Official GitHub Repository — The OpenAPI Initiative
Tutorial: Learning the New OpenAPI Specification: You can find documentation for OpenAPI 3.0 and Swagger 2.0 Specification on Swagger.io. The updated documentation includes a detailed look at the updated structure and new features in the 3.0 specification.
What Is the Difference Between Swagger and OpenAPI?: OpenAPI is the official name of the specification. The development of the specification is fostered by the OpenAPI Initiative, which involves more the 30 organizations from different areas of the tech world — including Microsoft, Google, IBM, and CapitalOne. Smartbear Software, which is the company that leads the development of the Swagger tools, is also a member of the OpenAPI Initiative, helping lead the evolution of the specification.
