Developing custom module in opencart 3

Question

I am trying to develop a module in opencart 3.0.2.0. I have created a new basic file in controller\extension\module\sellerlist.php.

    class ControllerExtensionModuleSellerlist extends Controller {
    public function index() {
return $this->load->view('extension/module/sellerlist');
    }
}

Then I created a view file in catalog\view\theme\default\template\extension\module\sellerlist.twig

I have created admin file with class ControllerExtensionModuleSellerlist in admin\controller\extension\module\sellerlist.php And created a view file in admin\view\template\extension\module\sellerlist.twig

When I checked in admin panel --> extension --> module, I couldn't find my new module in that list.

What could be the reason for that? Thanks for any help.

Did you forget to create the admin language file for it?

There is material on the web to show you all the files needed for it. This blog is a popular one: https://webkul.com/blog/create-first-basic-module-opencart/

You need all three of these files: language, controller and view files in the admin side .

If you don't have the language file, then there is no way you will even see the module listed to select it.

admin/language/extension/module/sellerlist.php

<?php

// Heading
$_['heading_title']    = 'Seller List';

$_['text_module']      = 'Modules';
$_['text_success']     = 'Success: You have modified "Seller List" module!';
$_['text_edit']        = 'Edit "Seller List" Module';

// Entry
$_['entry_status']     = 'Status';

// Error
$_['error_permission'] = 'Warning: You do not have permission to modify "Seller List" module!';
