How to hide frontend/web and backend/web in Yii2

Yii2 provide default url with frontend/web and backend/web. In real web application these type of URL is not well, So in this case we need to remove frontend/web from the URL. Below example is best to remove the frontend/web from the URL.

First of all you need to set enablePrettyUrl true and showScriptName false.

In second step you just replace frontend/web with blank space.

In third step you need to create a .htaccess file inside the web folder.

frontend/config/main.php

use \yii\web\Request;
$baseUrl = str_replace('/frontend/web', '', (new Request)->getBaseUrl()); // you set override the frontend/web with blank space and it will return the baseUrl.

'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'enableStrictParsing' => false,
        'rules' => [
        ],
   ]

'request' => [
 'baseUrl' => $baseUrl,
 ]
