V8Js::compileString():14026: ReferenceError: window is not defined

[kkyu27]

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\File;

class AppController extends Controller
{
  private function render() {
   $renderer_source = File::get(base_path('node_modules/vue-server-renderer/basic.js'));
   $app_source = File::get(public_path('js/entry-server.js'));

   $v8 = new \V8Js();

   ob_start();

   $v8->executeString('var process = { env: { VUE_ENV: "server", NODE_ENV: "production" }}; this.global = { process: process };');
   $v8->executeString($renderer_source);
   $v8->executeString($app_source);

   return ob_get_clean();
 }

 public function get() {
   $ssr = $this->render();
   return view('app', ['ssr' => $ssr]);
 }
}

I followed https://dzone.com/articles/server-side-rendering-with-laravel-amp-vuejs-25 this page and
installed V8Js.
But $v8->executeString($app_source); make an error that
V8Js::compileString():14026: ReferenceError: window is not defined.

I have no idea how can I handle this error..

Looks like things are (meanwhile) wrong with the tutorial -- haven't tried it out myself.

Yet the JS source tries to access window which is a browser API thing and not JS core itself. So you need to modify the JS code you execute via executeString to not directly access window. Either you don't perform the access at all or you provide a shim object.

thank you, I realized what is the problem.

@dinhhoainam23894 hey, check your vue.js or app.js

the cause was using Window object like bootstrap before serverisde sentence.
try annotation each line then you are gonna see ssr is worked!
