onlineshop | Online Shop Project for training ASP.NET MVC course | Ecommerce library

Im working on a onlineshop with php.

I work with the mvc model and I divide each small part of my application in: model view controller and service ( service is there for the query ).

So for example I would have a Item cart which is divided in discription and price...

For each of them I would have a seperate query, for example the discription: 'SELECT discription OF ... WHERE ...'

So my questin is:

Is there any downside ( like a worse performance ) if I use many simple MySQL queries instead of one complex query?

Trying to make a select filter with all the unique coins, but not getting to the end of it correctly.

When looping through data I can get a list of all the coins like this.

I'm importing a datalist (array of objects) from a file. I think i am right to import it into the App.js file and then working with props. I would like to map through it in my Card.js components which will then be imported to the Overviewpage.js file to display the cards when redirecting to this page. Unfortunately i am getting the error from the title in chrome and nothing gets displayed. Or I can't really map through the list even when trying to console.log it.

first the App.js file

I´m working on a onlineshop.

I need to require the "nav_bar.php" file into the "item_page.php" file.

Here´s my directory:

When I do manage.py makemigrations An error like this occurs

I'm pretty new to React Native, I have the following tab bar navigation page:

I'm learning socket.io and typescript. I'm currently building an app where I want to emit event on databases changes to the client.For the backend, I'm using Express, typescript and nodeJS

I've looked on a lot of posts but I don't understand how I can access my io instance to be able to emit my event from my controller functions. Also most examples are on javascript which is more confusing.

Currently in my app.ts I have the following configuration. How can I move my addOnlineHandler, logOutHandler and sendNotificationHandler in my controller functions to be able to emit event on database change directly from createOrder function of the controller ?

I've tried importing all orderHandler function in the controller but it's not working. I'm unable to access the io instance to emit events.

We are running a magento 2 onlineshop where we also serve some CMS pages.

I need to set the environment variable MAGE_RUN_CODE to app if the user is on a mobile device.

Currently the variable is set to app if the user accesses my website via app.company.de. If he uses company.de then default is set.

I´m working on a onlineshop and want to have two toggle menus on each side of the shop.

When I click on 'personal' or 'shopping cart' the toggle menus open. And when I click on 'back' they close again
( see images below ).

So my problem is, that on the right side, it works well, but on the left the text inside the toggle menu will not disapear after closing the menu ( see images below ).

I´m working with the 'width' property here. So when I'm clicking on 'back' the width will be set to '0px'. And ´whe clicking on 'personal' or 'shopping cart' the width will be set to '285px'

( I'm working with 'width' because I want to have a transition )

Here's my code:
