vertx-oas

Generates a Swagger/OpenAPI specification from a Vert.x Web Router.

Usage

Assuming you're using Vert.x Web, use it with your Router as follows:

// your normal Vert.x Web Router with paths etc.
Router router = Router.router(vertx);
router.post("/users").handler( routingContext -> { /* etc... */ });
router.get("/users/:userId").handler( routingContext -> { /* etc... */ });

// publish the Swagger/OpenAPI specification to a URL
RouterSpecGenerator.publishApiDocs(router, "/api/spec");

In this example, the specification is published to /api/spec.

You can obtain YAML or JSON versions of the specification by adding the appropriate file extension.

---

For example, fetching /api/spec.yaml would produce:

openapi: "3.0.1"
info:
  title: "Vert.x APIs"
  description: "This specification was generated from a Vert.x Web Router."
paths:
  /users:
    post:
      parameters: []
  /users/{userId}:
    get:
      parameters:
      - name: "userId"
        required: true
        allowEmptyValue: false

Limitations

• Doesn't understand regex paths
• Doesn't know the type of path parameters
• Doesn't know about request or response body models
