Things to Note

While Forking this Repo and trying to build the same, you might encounter this error Cannot find module './shared/firebase.config' in app.module and enviornment

This is because i have some Production and Development Enviornment Settings that load my Firebase Details accordindly, you need to create your own firebase credentials.

So what you need to do is to create a file named as firebase.config.ts in Shared folder and add your Firebase Credentials to the same , with a Structure like this in your firebase database

Like -

export const firebaseConfigDev = {
    apiKey: "XXXXX",
    authDomain: "XXX",
    databaseURL: "XXX",
    projectId: "XXX",
    storageBucket: "XXXX",
    messagingSenderId: "XXXX"

and like wise for prod if any

export const firebaseConfig = {
    apiKey: "XXXXX",
    authDomain: "XXX",
    databaseURL: "XXX",
    projectId: "XXX",
    storageBucket: "XXXX",
    messagingSenderId: "XXXX"

This credentials will be given by Firebase when you create a new Webapp inside of ther console if any doubts please comment or get in touch .
