require('./bootstrap');

window.Vue = require('vue');

resources/js/bootstrap.js


window._ = require('lodash');
try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

window.axios = require('axios');

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
import Echo from 'laravel-echo';
window.xxx = 'xxx';
window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true
});

i ran

npm run dev

here is the result

in my view i have


<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel</title>
        <meta name="csrf-token" content="{{ csrf_token() }}">
        <script src="{{ asset('js/app.js') }}" defer></script>
        <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    </head>
    <body>

    <script>
        console.log(Echo);
    </script>


    </body>
</html>

i keep getting

Uncaught ReferenceError: Echo is not defined
i even added

window.xxx = 'xxx';
in bootstrap.js to see if i can eccess xxx variable in my view but thats undefined as well (btw im not sure if thats how it works !! just trying some stuff )

any idea ?

my folders structure is like

/pusher (root folder)
  +app
  +vendor
  +node_modules
  +resources/js
  -public
    index.php
    css/app.css
    js/app.js

Could it be because of the defer attribute on your first script?
