In the article, we reviewed the Swagger tools for working with Open Specification files, as well as the libraries and converters available for various languages and platforms.
SwaggerHub
SwaggerHub is a powerful set of tools for API design and documentation. It has limited free features and rich commercial features. It is designed for teams working with OpenApi. SwaggerHub has rich searching, versioning, real-time commenting, and issue tracking features.
Why to choose SwaggerHub? Because, you can do with it:
SwaggerHub provides a search tool for public OpenApi documents (navigate to the link). Among them are a few noteworthy examples that you can use as a starting point for your own future project. For instance, consider the ready2order public API:
Swagger UI
The Swagger UI tool automatically generated from OpenAPI Specification, with the visual documentation. You can use it with local and remote (e.g. GitHub) files.
Swagger UI is an open source project that provides a graphical interface for interacting with the OpenAPI (Swagger) document. The Swagger UI enables you to visualize and interact with the API’s resources.
You can test the tool by typing https://petstore.swagger.io/ into your browser.
With Swagger UI, you can inspect your GitHub OpenApi specification file by entering its raw file address in the Swagger UI address field.
Swagger Editor
The Swagger Editor is an easy way to get started with the OpenAPI Specification. You may have CORS-related problems during working with it – use FireFox Developer with CORS Everywhere addon to avoid the problem.
Swagger Editor validates your content dynamically as you type. It enables you to determine the validity of your OpenApi document. You can use Swagger Editor as a web application (see the link), download and launch it from a local folder, or you can install it in a Docker container and run it from there.
Swagger Inspector
The Swagger Inspector tool enables you to immediately begin testing in your browser. Tests are automatically saved, and you can access them from any location. No download and installation required-only a free subscription. You can also login using your GitHub credentials.
To load an API definition, click Definition, click on the upload icon (red circled) to upload a file or specify the URL of your OpenAPI or WSDL file, and then click Parse.
Then you can select an http method, specify the parameters, and send a request to test the API definition:
Swagger Libraries and Converters
We listed some useful libraries for coding purposes as well as converters for managing OpenApi files in this section.
The libraries for developers:
- Swagger Parser – standalone library for parsing OpenAPI definitions from Java.
- Swagger Core – Java-related libraries for creating, consuming, and working with OpenAPI definitions.
- Swashbuckle. AspNetCore. SwaggerUI – middleware to expose an embedded version of the swagger-UI from an ASP.NET Core application.
- Swashbuckle. AspNetCore. SwaggerGen – Swagger Generator for API’s built on ASP.NET Core.
The converters between different formats:
- OpenAPI Filter – Filter internal components from OpenAPI Descriptions.
- openapi-to-postman – Convert OpenAPI 3.0 specs to the Postman Collection (v2) format.
- pyswagger – Client & converter in Python, which is type-safe, dynamic, spec-compliant.
- swagger2openapi – Upgrade files from OpenAPI v2.0 to v3.0, bundling into one mega file or respecting $refs. Part of oas-kit.
