This heavily depends on the framework you choose to use, and modern Ionic uses the stock tooling your framework does, so build times should be on par with any other project of that framework type. Earlier versions of Ionic had custom tooling and much slower build times.

This was happening in an Ionic 4 project which was already using the stock tooling of the framework (Angular CLI). But I remember it being worse in Ionic 3 with its custom tooling, so overall things do seem to be improving with time.

My findings at that time (it was a while ago) seem to match exactly the slowdowns described in this issue [1]. Just importing the IonicModule in a new Angular project (without actually using any Ionic component) made the dev server build times jump from around 200 ms to a couple of seconds. And the situation only seemed to get worse as more Ionic features were being added to the app.

Just to make it clear, I understand that this is an open-source project and I don't expect anyone to fix my issues. And I'm also very grateful to you and the Ionic team for giving us Capacitor which is such a big improvement from Cordova.

So I don't like being all negative in here. But I did encounter a fair share of issues with Ionic and I'm only sharing my experience here as just another data-point in case it helps someone make a well-informed decision.

And I have to say, the overwhelmingly positive reaction to Ionic in general did make me question my own abilities several times. Maybe I just don't "get it". I still haven't ruled that out as a possibility.

Thanks for the info. I do think the choice of Angular here is significant. Angular builds have historically been very heavy. Later versions have sped things up and Ionic apps have gained from that. I haven’t seen slow builds in React, for example.
