How to do a phased rollout?

[kyllerss]

I was hoping for some advice. I'm using a live URL in my app. I am seeing errors coming from clients that are still on the old build but are being served content from my servers that assumes they have the latest build.

This is not a major issue for me at the moment as most of my users are testers, but it does make me wonder about how phased rollouts are supposed to work.

The error people are running into is that the CdvPurchase namespace is not defined. Normally with a Capacitor plugin I can check to see if a plugin is available, but I didn't see a way of doing the same with cordova-plugin-purchase.

How can one test for the availability of this plugin in a phased rollout scenario?

CdvPurchase.store.initialize(....).then(ok=>...).catch(err=>...)

You have to check if the Initialize was successfull and if not the plugin is not available or has a different error...
