How to change yii2 default module - module

Question

Hello I am not an expert in Yii2 and would appreciate any help, We want to change our default module,
Our logic:
site implements a use of wildcard domain, https://example.com,
we implement a bootstrap component to Identify a use of a "subdomain" in the
url I.E. https://sub.example.com,
$config = [
'id' => 'basic',
'name' => 'exapmle',
'basePath' => dirname(__DIR__),
'bootstrap' => [
'log',
'devlogin',
'app\components\SubBootstrap', #this is the bootstrap component we use
'app\components\ThemeBootstrap',
],...
now we would have liked to use the same logic to change the default module to a new "submodule" but we can't use the bootstrap because it happens after the default module has been applied.
obviously we can have an explicit url call for the module I.E.
'modules' => [
'sub'=>[
'class' => 'app\modules\sub\Module',
],...
but that means that the url would look like https://somesub.example.com/sub/ which is undesirable.
thank you very much

In your case, what you can do is override the UrlManager component and manually adjust the path to reflect the module that you want to envoke behind the scenes.
So your code would look something like this:
<?php
namespace app\components;
use Yii;
class UrlManager extends \yii\web\UrlManager
{
public function parseRequest($request)
{
if (!empty(Yii::$app->sub)) {
$pathInfo = $request->pathInfo;
$moduleIds = array_keys(Yii::$app->modules);
$inModule = false;
foreach ($moduleIds as $moduleId) {
if (preg_match("/^{$moduleId}/", $pathInfo)) {
$inModule = true;
break;
}
}
if (!$inModule) {
$pathInfo = 'sub/' . $pathInfo;
$request->setPathInfo($pathInfo);
}
}
return parent::parseRequest($request);
}
}
and then in config/web.php:
'urlManager' => [
'class' => 'app\components\UrlManager',
...
],

You don't need to change the module configuration. You need to change web-server path to this module and architech the UrlManager rules;

Bootstraping yii module it's only some way to load it before another components.
