&gt; Here&#x27;s a schema I use in production, see how readable it makes the parameters of the API and how quick all the validation and normalization is: <a href="https:&#x2F;&#x2F;www.pastery.net&#x2F;mhwwnv&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.pastery.net&#x2F;mhwwnv&#x2F;</a><p>Thank you so much for providing this example. I couldn&#x27;t grok what schema did, and your code made it make sense.<p>If people want to provide examples for the other libraries in this thread, you&#x27;ll be popular :)
