What is oxpress?

Do you like TypeScript, Express and OpenAPI and use those tools for API development?

Then oxpress is made for you. Oxpress is a code generation tool, which generates a type-safe Express server based on your OpenAPI Document.

Design First Approach

Unlike other tools like tsoa, oxpress fully embraces the design first kind of API development.

To sum this up: The design first approach puts the OpenAPI Document first, and your server just becomes an implementation of your specification.

Type Safety

OpenAPI makes you able to describe your API in great detail. Why not have this amount of detail within your Express-Application? The following parts of Express are fully typed by oxpress:

• Routes
• Route Parameters
• Query Parameters
• Request Body (JSON)
• Response Body (JSON), in conjunction with the Status Code

Integrated Validation

Oxpress uses express-openapi-validator by default to validate parameters. This ensures, that your beautifully typed parameters and responses are also type safe during runtime.
