Hey @billy1624, I thought it'd be easier to just take out the core stuff. I wonder if this structure is good enough for the example, or should I add the api crate and put the rocket code in there?

[billy1624]

Hey @shpun817, the new workspace structure looks exactly like what I'd expect :)

I think we should make it explicit by moving codes that are currently in project root inside the new api crate.

@billy1624 Finished transforming the Rocket example!

Hey @shpun817, LGTM!!

Could you please update all other examples as well?

It's going to be tedious zzz

Hey @shpun817, @fergus-hou just added an SeaORM example for Salvo. Could we add mock testing to it as well?
