Ionic 5.2.8

Does IONIC 5.2.8 have routing module?

The only aspect of “Ionic” with a major version number of 5 that exists at the moment is the CLI, which is a completely different animal from the framework itself, so the answer to the question you actually asked is “no”, but I suspect that’s not really what you want to know.

If you’re asking whether you can do routing in current Ionic apps, yes, and if you want to use the Angular router, you can. There is an Ionic-specific veneer over it that provides some extra animations, if you want to use that.
