I want to send a push notification from the web app to the android mobile app users using firebase.

Just for your information if you want to send notification for testing purpose then you can use FCM console which provides you a way to pass data payload.
But in case your need you can have your own server too where you can pass your own data and notification payload

I'm experimenting by transfering cookies from one browser to another and I was surprised that all accounts I'm logged in to are also logged in in the new browser. My Whatsapp session however doesn't get transfered, I looked at the Whatsapp cookies and there were none of them.
How does Whatsapp keep me logged in? And is there a way to transfer one Whatsapp session to another browser?
WhatsApp web does not use cookies Instead, it uses offline website data.

You might be able to transfer the data if you can find it.

I have setup a webhook, that facebook posts data to. Basically its just a test webhook using https://webhook.site/.
Now how do i reflect this data on my client side (I am using react using create-react-app, but even a generic solution without using create react app will do ), How do i listen to this data, so i can refesh my frontend and show this data on my frontend.
You need a server that can listen to incoming requests. From this server you could establish a websocket connection to your frontend to reflect these changes in real time.

Hello World Express (Node.js)
Get Started with socket.io (Websocket wrapper)

Sorry for question but I don't understand that.
I have this:
<a #click.prevent="Submit(0)" href="#">NO</a>
<a #click.prevent="Submit(1)" href="#">OK</a>
Now in my vue method submit I want to post value 0 or 1 to my api and then store it in database. I have controller UserVote and model Vote. I am green here.
How my link should do? Where I post that? How I can upload that to db? I need just know, then I will be know everything.
You can create a method in VueJS that does a API request to some endpoint in your Laravel application. Just send the data to your endpoint and let the PHP controller handle the transmitting to the database.

I'd like to create an app to filter my notifications from Facebook. For example I'd like to get all notifications about someone commenting in conversations I also took part on given Facebook group.
As #lushn pointed out below, Facebook removed the ability to access notifications in their Graph API.
Now I wonder, is there a better (and more official) way to fetch notifications from Facebook than to pose as a browser and parse HTML (for that I'd also need a proxy written in some server language, due to CORS)?
Access to notifications is not possible anymore, the required permission and the endpoint for this has been removed with v2.4 of the Graph API: https://developers.facebook.com/docs/apps/changelog#v2_4

I am working on a Laravel project right now. I have a route www.website.com/auth/register. All I want is that when a hits this page, he should be asked for some credentials. If he inputs incorrect credentials, then he should not be able to see the registration page.
I have seen some web pages ask for authentication before we can see them. How is that achieved? I suppose those credentials are handled on the client side by the browser. Please help.
I think you're talking about the BASIC Authentication method, which exchanges credentials in plain text and is configured at the Web Server level.
