Handling events and notifications

I am writing an events app, in this there is a part called my events which has all the events that I register for. This is fetched using REST API,
So wherever I fetch this I need to hold this list in my app. And also send a notification in the app before 1 hour of the event.

Wondering how to do it. Simpler way I see is using “add to calendar” as button i event list and use cordova calendar plugin. or we can automatically add to calendar when fetching the list.

Is there any other way to do this? without interacting with mobile’s calendar?
