Deploy and Host Swagger UI on Railway

Swagger UI allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources without having any of the implementation logic in place. It’s automatically generated from your OpenAPI (formerly known as Swagger) Specification, with the visual documentation making it easy for back end implementation and client side consumption.

Example Swagger UI

There are a lot of environment variables you can change to control the behaviour of Swagger UI. See the Pre-Configured Environment Variables.

About Hosting Swagger UI

Swagger UI requires an OpenAPI specification which describes your API. It then builts a visual and interactive web documentation based on this specification. This file should be hosted and accessible on a public URL.

This template has multiple environment values that control the behaviour of Swagger UI. A full overview of these options can be found here.

Common Use Cases

Create an API documentation for your development team
Let users and developers try out your API without having to set up any code or config
