Notes

These two libraries pretty much do the same thing, but with different interfaces. I personally recommend using express-openapi-validate (Solution #2). Though we need to write code to manually add a validator each route defintion (compared to Solution #1), it throw better errors that we can catch in our error middlewares and send back to the client.
