Well… I asked the (admittedly poorly phrased) question: "With deno and oak, how can I validate the input and cast it in the different routes?" Phind suggested "one way is to use the built-in validation middleware provided by Oak, called validator.". It went on to describe this middleware, its helper functions and give me code examples how to use it. Thing is: This "validator" middleware does not exist. I asked for more examples, and Phind provided me with more examples, listing all validation functions. When I said that there is no such thing as a built-in validator middleware in Oak, Phing admitted that it appears to be removed in version 6.0 (we are currently at version 11), according to the Oak documentation (with a link to it's Github repo - where I did not find any match in code for "validator").
