Environment-Specific Base URL Resolution The OpenAPI specification utilizes a servers array to define the base URLs for API requests. While relative paths often resolve correctly in local development environments, the behavior changes when the Swagger UI is deployed to production behind a reverse proxy or API Gateway. When the UI is hosted on a different dom
We deploy Swagger UI as static files behind a reverse proxy that serves the application from a subdirectory. The UI loads, but instead of listing operations it displays a fetch or parse failure for the API definition. Relative spec paths resolve against the page URL, so a subdirectory deployment can request the wrong document, and a malformed or partially co
Goal Make FastAPI's built-in interactive documentation at /docs and /redoc meet WCAG 2.1 AA accessibility requirements without forking FastAPI or self-hosting a separate static asset pipeline. Constraints FastAPI serves Swagger UI v4.x and ReDoc automatically. The bundled Swagger UI build has accessibility gaps, including missing ARIA labels and incomplete k
When an OpenAPI 3.x document defines multiple servers entries, Swagger UI renders them as a dropdown for "Try it out" requests. The first entry in the array is selected by default, yet the behavior after a user changes that selection and reloads the page varies across releases and embedding contexts. Recent standalone Swagger UI distributions appear to persi
Interactive Documentation Constraints When deploying a public-facing developer portal using Swagger UI (OpenAPI 3.x), there is a design trade-off between providing an interactive testing environment and preventing unauthorized or accidental mutations of live data. The UI allows for the control of the "Try it out" functionality through specific configuration
