Jira Ticket: PXP-9641

New Features

• code to let Atlas send "keep session alive" messages to its parent (when Atlas is running in iframe)

@alilahrime add this to your code in the main app:

   const EVENT_TYPE = "message"; // from event types https://developer.mozilla.org/en-US/docs/Web/API/EventSource/message_event

    window.addEventListener(EVENT_TYPE, function(event) {
        console.log("got message (event.origin): " + event.origin); // you can use this to check if message is coming from  atlas...
        console.log("got message (event.data): " + event.data);
        // CALL gen3 function to refresh session:
        // ??
    });

@m0nhawk is there a gen3 function we can call to refresh a session ^^ ?

The data-portal is doing the following here:

  oniframeLoad = (e) => {
    // force workspace iframe acquire focus if it does not have yet
    // to fix the noVNC workspace doesn't respond to keyboard event when came up
    e.target.focus();

    // add event listeners for sessionMonitor timeout
    const iframeContent = e.target.contentDocument;
    if (iframeContent) {
      iframeContent.addEventListener('mousedown', () => sessionMonitor.updateUserActivity(), false);
      iframeContent.addEventListener('keypress', () => sessionMonitor.updateUserActivity(), false);
    }
  }

I would expect it can be done similarly, but better to check with other frontend developers on this.

@m0nhawk thanks for sharing this code. Do you think this can be done cross-domain as well? Not sure if our Atlas installation will be on a different domain?

[m0nhawk]

Yes, it's expected for Atlas and WebAPI to be on a different domain.

And... I'm not really sure how to do that cross-domain, I haven't tried that before.

[pieterlukasse]

@m0nhawk thanks for the info. For cross-domain scenario I think it has to be implemented like we are proposing in this PR (with postMessage and an event listener on the other side). See also https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

Are we merging this one? The code seems to be on QA already
