title: Node.js OpenAPI 3 Validation Library
body: <p>I have yet to see any libraries in existence that support OpenAPI request validation. Or to that matter any projects that are under active-development that does as such.</p>
  
  <p>Would very much like to write middleware in my microservices to validate based on OpenAPI 3 specs instead of Swagger/OpenAPI 2 specs.</p>
  
  <p>Examples</p>
