GTM to Catch Events

Firing Tags

You can add Page Views Tags or Tags on the basis of data layer variable values. You can All Page Route Change trigger for your react app. to check for the tag firing conditions.

Events Capture

You can add Custom Html Tag for capturing events that you are firing from your app using this module. (CustomEvent : object should be supported by your browser version.)

< script > document . addEventListener ( ' ga-event ' , function ( ev ) { console . log ( ev . detail ) ; } ) ; </ script >

If you have your app server side rendering try using functions in your user interactive functions or componentDidMount which runs only on browser as the document object might not be present on server side. And use reactFlag option as true for adding the component to your component render function.
