Application operation

This application has a good file structure for separating tasks in the back-end: app, router, controllers. Many websites are used in large web-apps. Handling multiple pages in one file - causes confusion and lack of order. Therefore, tasks are divided into different folders and files. GET commands are handled by PagesController.js, POST by ApplicationsController.js and separation is handled by: \routes\index.js.

Pages are switched via the Get method. The router finds the correct EndPoint and based on it, renders the page to the browser. On Log page - the button sends login data to the Node server using the POST method. The server analyzes these login details. If the data is correct - the Node will return a table for display.
