Example usage of custom DTM setup

site.js

window._satellite.pageBottom();
var dataLayer = {};
window._satellite.setVar('dataLayer', window.dataLayer);
// apply defaults that persist throughout session:
Object.assign(dataLayer, {
  eVar1: '...',
  channel: '...',
  heir: '...',
});

// sample function for interactions:
function trackInteraction(linkName, extraVarsOrEvents) {
  addExtraVarsOrEvents(extraVarsOrEvents)
  dataLayer.linkName = linkName;
  window._satellite.track('interaction');
  removeExtraVarsOrEvents(extraVarsOrEvents)
}

// sample function for pageViews:
function trackInteraction(pageName, extraVarsOrEvents) {
  addExtraVarsOrEvents(extraVarsOrEvents)
  dataLayer.pageName = pageName;
  window._satellite.track('pageview');
  removeExtraVarsOrEvents(extraVarsOrEvents)
}


// shared helpers
function addExtraVarsOrEvents(extraVarsOrEvents) {
  for (var key in extraVarsOrEvents) {
    // s.eVar3 = 'viaFacebook'
    // s.event1 = 'login'
    dataLayer[key] = extraVarsOrEvents[key];
  }
}

function removeExtraVarsOrEvents(extraVarsOrEvents) {
  for (var key in extraVarsOrEvents) {
    // blank string is "null value" (not added to next call)
    dataLayer[key] = '';
  }
}
