The Inspector provides a way to look at all Promises created in your application. Click on the
Promises menu to start inspecting them.
You can see a hierarchical list of Promises with labels describing each Promise, its state, its settled value, and the time it took to settle.
Promises have different colors based on their state.
You can filter by clicking on the following pills:
You can also search for Promises by typing a query in the search box.
To clear the currently logged Promises, click on the clear icon on the top left of the tab.
If the fulfillment value of a Promise is an Ember object or an array, you can click on that object to open it in the Object Inspector.
If the rejection value is an
Error object, you can send its stack trace to the console.
You can also click on the
$E button to send the value to the console.
The Inspector provides a way to view a Promise's stack trace. Tracing Promises is disabled by default for performance reasons. To enable tracing, check the
Trace promise checkbox. You may want to reload to trace existing Promises.
To trace a Promise, click on the
Trace button next to the label, which will send the Promise stack trace to the console.
Promises generated by Ember are all labeled by default. You can also label your own RSVP Promises to find them in the Inspector's Promises tab. All RSVP methods can take a label as the final argument.
let label = 'Find Posts' new RSVP.Promise(method, label); RSVP.Promise.resolve(value, label); RSVP.Promise.reject(reason, label); RSVP.Promise.all(array, label); RSVP.Promise.hash(hash, label); promise.then(success, failure, label); promise.catch(callback, label); promise.finally(callback, label);
