Zero

It’s pretty interesting, but given not all data can be replicated as cache on the front end, I don’t think it makes sense to say there’s zero latency.

A gripe I have with “full stack frameworks” is that they are primitive on the service layer. Encouraging users to write one off queries in components (like in the example) can be taken literally and often is. When this happens people adopt it like that and readability suffers. I’d encourage you to demonstrate with your examples calling a service for data rather than building a query for this reason.
