How can I send information from a web server to an Electron app?

I am in the process of building an electron which will eseentially provide "notifications" when a certain form is filled out in a certain service that is connected via oAuth2.

I am having trouble, however, finding any information about the process that (i think) will need to happen.

I am thinking...

a user submits form A from this web service

that web service CAN (not sure if this is the way to go) do a HTTP post to my server

then I was thinking that my server could send that info over to the electron app. I've looked into 'https://www.npmjs.com/package/electron-workers', but i'm still unclear if this could help solve my problem.

Any help or even a nudge in the right direction would be greatly appreciated!

You have multiple way to do that, but this can only simply be done from the renderer process from Electron (basically your front-end),

Use a web socket for real-time application

Web socket is a technology that enable real-time communication between server and client. The most famous is socket.io. You can have a look at Web Sockets API too.

Set an interval that do an Ajax request to your server

var checkNotifications = function() {

    var r = new XMLHttpRequest();

    r.open("POST", "url/of/your/notifications", true);

    r.onreadystatechange = function () {
        if (r.readyState != 4 || r.status != 200) return;
            alert("Success: " + r.responseText);
        };

    r.send();
}


setInterval(checkNotifications, 5000); // every 5 seconds

Electron is running a local node http server, but it's not a public address. Max Ogden has mentioned - I think in the "State of Electron" youtube talk - installing a "headless" electron app on a public webserver to do some service related stuff, but basically you have to have a reachable address. Do you want a desktop webserver to have a public URL?
