Here, we need to add one route with FirebaseController controller so let's add that route in web.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\FirebaseController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class FirebaseController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        return view('firebase');

        var number = $("#number").val();
          
        firebase.auth().signInWithPhoneNumber(number,window.recaptchaVerifier).then(function (confirmationResult) {
              
            window.confirmationResult=confirmationResult;
            coderesult=confirmationResult;
            console.log(coderesult);
  
            $("#sentSuccess").text("Message Sent Successfully.");
            $("#sentSuccess").show();
              
        }).catch(function (error) {
            $("#error").text(error.message);
            $("#error").show();
        });
  
    }
  
    function codeverify() {
  
        var code = $("#verificationCode").val();
  
        coderesult.confirm(code).then(function (result) {
            var user=result.user;
            console.log(user);
  
            $("#successRegsiter").text("you are register Successfully.");
            $("#successRegsiter").show();
  
        }).catch(function (error) {
