Ez push notification JS lib

An api wrapper around firebase aiming to offer a trouble-free usage of firebase upon legacy es-5 projects.

Usage via CDN

Step 1: Load Js Scripot through CDN

    <script src="https://cdn.jsdelivr.net/npm/@techins/pushnotiflib@latest/dist/firebaseLib.umd.js"></script>

Step 2: Create firebase-messaging-sw.js

Ensure that firebase-messaging-sw.js is servesd through / and via https.

In order for the firebase to work you must create a file firebase-messaging-sw.js. The file should be accessible via https at:

https://^your_domain^/firebase-messaging-sw.js

Keep in mind that firebase-messaging-sw.js does not work if not served in http as mentioned above.

firebase-messaging-sw.js content

Its content should be:

importScripts("https://cdn.jsdelivr.net/npm/@techins/pushnotiflib@latest/dist/firebase-messaging-sw.js");

const firebaseConfig = {
    // Replace firebase config from firebase console
};

self.initServiceWorker(firebaseConfig);

The firebaseConfig is the config generated from the firebase console.

Step 3 Use the library:

The library can be used like this:

const firebaseConfig = {
    // Firebase config
};
            

const vapidKey = ""; // Also generated from firebase console

// Initialize Firebase  
firebaseLib.pushNotificationInit(firebaseConfig,vapidKey)

Both firebaseConfig and vapidKey are retrieved from firebase console.

Further token reiceival handling:

The function pushNotificationInit recieves the folloing arguments (with rthe order provided):

• firebaseConfig that is the configuration received from firebase console
• vapidKey that also received via firebase console
• tokenNotificationCallback As documented bellow (optional)
• workerAsModule that indicates whether worker should be loaded as a module or not.

Upon token receival you can offer to be processed futher via providing a callback function at tokenNotificationCallback. The function provided should be like this:

function(token,proceedCallback)
{
  // Send token via ajax or do stuff
}

In order to receive messages you must call proceedCallback function. In order to indicate that the process sucessfully has been ended you should do:

function(token,proceedCallback)
{
  // Send token via ajax or do stuff
  proceedCallback() // Success
}

Otherwise you should provide the error as an argument:

function(token,proceedCallback)
{
  // Send token via ajax or do stuff
  proceedCallback() // Success
}

A full working example is:

const firebaseConfig = {
    // Firebase config
};
            

const vapidKey = ""; // Also generated from firebase console

function handleToken(token,proceedCallback)
{
  // Send token via ajax or do stuff
  proceedCallback()
}

// Initialize Firebase  
firebaseLib.pushNotificationInit(firebaseConfig,vapidKey,handleToken)
