🦋 express-openapi-validator
An OpenApi validator for ExpressJS that automatically validates API requests and responses using an OpenAPI 3 specification.
🦋express-openapi-validator is an unopinionated library that integrates with new and existing API applications. express-openapi-validator lets you write code the way you want; it does not impose any coding convention or project layout. Simply, install the validator onto your express app, point it to your OpenAPI 3.0.x or 3.1.x specification, then define and implement routes the way you prefer. See an example.

- ✔️ request validation
