Why does the vue js not working in my laravel project

Question

I have a laravel project with some custom changes I have tried to use Vue js code but is not working in my case I have run all the required commands but still not working when I check console it says message is not defined .

My webpack.config.js

 const mix = require('laravel-mix');

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |--------------------------------------------------------------------------
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.
 |
 */

mix.js('resources/js/app.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css');

My app.js

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */

require('./bootstrap');


window.Vue = require('vue');

import Vue from "vue";
//import Vue from 'vue/dist/vue.js';


// const files = require.context('./', true, /\.vue$/i);
// files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default));


const app = new Vue({
    el: '#app',
    data:{
        message: '',

    },
    methods: {
        send()
        {
            console.log(this.message);
        }
    }
    //
});

My layouts/app.blade.php

You should 1) start with the error:

app.js:1 ReferenceError: message is not defined
    at hn.eval (eval at Sa (app.js:1), <anonymous>:1:424)
    at hn.e._render (app.js:1)
    at hn.r (app.js:1)
    at Nt.get (app.js:1)
    ...

then 2) work your way backwards:

require('./bootstrap');

window.Vue = require('vue');

import Vue from "vue";
//import Vue from 'vue/dist/vue.js';

// const files = require.context('./', true, /\.vue$/i);
// files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default));

const app = new Vue({
    el: '#app',
    data: {
        message: '',
    },
    methods: {
        send() {
            console.log(this.message);  // <-- Do you have a "this.message" in app?
        }
    }
});

So perhaps the solution is console.log(this.data.message); Please try it, and post back what you find.

More importantly, please familiarize JS debugging tools, for example Visual Studio Code and/or Chrome Developer Tools.

Triied this.data.message Still the result is same

Q: Does commenting out "console.log()" resolve the error? Q: Have you tried stepping through the code in a debugger (either VSCode or Chrome debugger)?
