And yes - this is actually totally doable. I've done it so far for platforms like Wordpress, Shopify, and Magento, as well as a couple custom internal admin tools of customers so far.
It isn't something I have standard pricing and docs on yet but I am totally open to doing that. Do you have a use case in mind?
Why? Ongoing "battle" between a large CMS (AEM) and a more modern SPA using microservices. Our claim is that the SPA is actually a superset of everything. It can SSR (like the CMS), it can also get data to display (like the CMS). All that is missing is a service for such data (we have other services delivering domain specific data).
Now the problem is not in a data service, but rather in the whole infrastructure around it - to make it easy for an content editor to use. These people like drag and drop and they would love your solution.
Great job!
