Refine server side validations

[apoorv-mishra]

Currently, different types of validations for a given API are scattered within the handlers as a bunch of assertions, added on ad-hoc basis. This ends up making handlers fat and cluttered. It'd be good if validations could be pulled out and be handled more declaratively, in one place, possibly through a middleware. It'd be worth exploring Zod for this purpose.

Now we're talkin'.

I think we should write our own middleware based on zod, as you say – but this express one might provide some inspiration:
