Add /api/healthz endpoint to frontend

i'm struggling to understand what you mean by this. What is the user story here?
should frontend have its own api? should it just show a component with health? redirect response from the api?

What is the user story here?

I hoped that would be explained by the wording and the link under the context section. Kubernets needs something reachable in order to determine if it's alive or not. Therefore, the frontend (which is running a server anyway to serve html) also need to have similar endpoint, although it doesn't need to reach to the database or anywhere else

Thanks for clarification.

One more thing:

we're still using sqlite and not psql, so if i remove the db file, startup the db, do select 1 - there will be no error + db file will be created. Same with pragme integrity_check query. I would then suggest doing a simple user query to make sure that there's "some" table

[valiafetisov]

Yeah, I guess it's fine to query a table (and not return anything from the endpoint) to better validate that prisma client is properly initiated
