Lifecycle callbacks

initialize: once, when the controller is first instantiated
connect: anytime the controller is connected to the DOM

To send a request via the sandbox, you can use pm.sendRequest.

pm.test("Status code is 200", function () {
    pm.sendRequest('https://postman-echo.com/get', function (err, res) {
        pm.expect(err).to.not.be.ok;
        pm.expect(res).to.have.property('code', 200);
        pm.expect(res).to.have.property('status', 'OK');
    });
});

Realtime Notifications with ActionCable

In this episode we're going to be adding realtime notifications into your app using ActionCable. We've talked about notifications a few times in the past and we used AJAX polling for that. 95% of the time, polling is the solution that would be recommended for it.

But if you're looking for a good introduction into ActionCable then this is a decent one because we're only really using it for one way from the server side to the client side.

Getting started

So to get started we're starting with an app that has Bootstrap installed and then we created a Main controller with an index view which is where we will list our Notifications as for this example.

Before we generate our channels let's install a few things
