I have a JavaScript helper method which handles a message sent from a child iframe
handleMessage: function (event)
console.log('handleMessage');
console.log(JSON.parse(JSON.stringify(event.data)));
,
The helper method is set during OnInit:
onInit: function (cmp, event, helper)
window.addEventListener("message", $A.getCallback(helper.handleMessage));
,
Once a message arrives in handleMessage I need a reference to cmp or component but I do not have it.
Question
- How can I access
cmporcomponentfrom inside thehandleMessagehelper method?

You can bind it to the function call. You'd want to make the following changes:
// Helper function
handleMessage: function (cmp, event)
console.log('handleMessage');
console.log(JSON.parse(JSON.stringify(event.data)));
,
// Main code
onInit: function (cmp, event, helper)
window.addEventListener("message", $A.getCallback(helper.handleMessage.bind(helper, cmp)));
