Custom widgets/validation?

[Osmose]

Copied from kinto/kinto#1083.

You can specify a schema for your data, and a uiSchema for how to build the form for it. I'd like to be able to add a custom type for a field (specifically, a JEXL expression) that has custom validation, and potentially a UI widget that helps in writing that custom type.

But that custom type doesn't seem like a thing I should, say, land in Kinto itself. I'd like to be able to write something like a plugin for Kinto that adds support for my new custom type to a Kinto instance. I dunno if that's already possible or how hard it would be to add, though.

Thanks!

This is an interesting use case, as we don't have anything to extend forms capabilities in the kinto admin just yet. Forms are powered by react-jsonschema-form, which supports custom fields, widgets and validators.

The idea here I think would be to extend the current admin plugin API to support registering custom fields, widgets and validators, and allow leveraging them through collections uiSchemas.
