rswag VS springdoc-openapi

We will be creating a "Coffee Ordering API" using Ruby on Rails, and using a tool called rswag to create tests that verify the behaviour of our API and generate an OpenAPI reference.

Made a library a while back that helped me write JSON schemas for rswag. Hope others find it useful!

Forem, which is a Ruby on Rails app, integrates Swagger via a gem - the rswag gem. The rswag Ruby gem allows us to create a Swagger-based DSL for describing and testing our API operations. It also extends rspec-rails "request specs”, hence, allowing our documentation to be a part of our test suite which allows us to make requests with test parameters and seed data that invoke different response codes. As a result, we are able to test what the requests and responses look like, however we do not test the business logic that drives the endpoint - that is tested elsewhere in the code.

Using something like rswag will give you some ability, in the specs, to also describe the endpoints and auto-generate some documentation.

Hello! I would like to autogenerate API documentation for my Ruby on Rails Application. However, all of the solutions I've found such as https://github.com/rswag/rswag and https://github.com/richhollis/swagger-docs involve writing tests or manually describing the endpoint responses. I am hoping to find something similar to Swashbuckle for ASP.Net Core but for Ruby on Rails. Below is an example of using Swashbuckle's ASP.NET Core to autogenerate Swagger API documentation. The response type is inferred form the return type of the action.

rswag expands the "request specifications" of rspec-rails with a Swagger-based DSL for defining and testing API activities. - Github

Hello guys, I'm working on a rails (4.x) project, trying to implement a way to create docs for OpenApi 3 and Swagger (I started to learn rails in october last year), this project has like 6 years old, a lot of endpoints and very poor documentation, my first option is Rswag, does anyone knows a good example project for these gem?

I'm using the Rswag gem to document my API. Right now I have a WIP here: https://cabal-fintech.herokuapp.com/api-docs/v1/swagger.json but whenever I try to validate it on the swagger validator I get an error not even understandable to me, as that route doesn't need [params].item

The issue is that the springdoc-openapi BOM brings an old version of the Spring Framework 6.0, which is incompatible with Spring Boot 3.2. There are several ways to solve this problem: update springdoc, change the order of BOM imports, but the best, in my opinion, is to avoid using the io.spring.dependency-management plugin.

I would suggest using Springdoc

The SpringDoc library comes with lots of annotations to tune your REST API specification precisely. Anyway, that's out of context of this article.

I found SpringDoc, a library that automates the generation of the spec from the source code. It relies on annotations for textual bits (like tags and descriptions), but it also infers stuff from Spring annotations.

This is an API made with Spring Web, uses springdoc-openapi-ui to expose a swagger-ui on http://localhost:8080/swagger-ui/index.html

Libraries like Springdoc or Springfox can do this. These libraries generate the OpenAPI documentation based on your controllers (+ you can apply the OpenAPI annotations on your controllers). This documentation is then exposed as a REST API, for Springdoc these can be found at /v3/api-docs.

Retrieving all endpoints of a service isn't the goal of a service registry like Eureka, so no, you can't get all endpoints of a service. You can use a library like Springfox or Springdoc to enable Swagger/OpenAPI for your project. These libraries generate a JSON REST API (and a user interface) to view all your endpoints. You can even provide additional information (eg. default values, descriptions, ...) by adding some additional annotations on your controllers.

The springdoc-openapi helps automating the generation of API documentation using Spring Boot projects GitHub - springdoc/springdoc-openapi

Our microservice accept http requests: For swagger used Swagger OpenAPI 3. The bank account REST controller, which accept requests, validate it using Hibernate Validator, then call command or query service. The main reason for CQRS gaining popularity is the ability to handle reads and writes separately due to severe differences in optimization techniques for those much more distinct operations.
