 [🦋express-openapi-validator](https://github.com/cdimascio/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 specification, then define and implement routes the way you prefer. See an [example](#example-express-api-server).
