Modules:

1. Network (kernel):

• connects/disconnects servers;
• sends Packages with a response to servers (TCP);

1. Intermediate (server):

• sends API responses to the client (HTTPS, WSS);
• sends Packages with a requests to the network (TCP);
• saves information in a database;

1. Interface (client):

• sends API requests to the server (HTTPS, WSS);
• single page application;
• native application routing;
