Main Goals :
1) Fixed the Frontend Request sending code. Properly added the Access Control in header to deal with CORS policy. And made the request function async to wait for response before working with response data.
2) Couldn't working on Web Project backend. I didn't have a database and also needed to make some system design plans. So did some research and tried to come up with a feasible plan. Currently it's using SQLite (GPT suggested PostgreSQL but we'll see) and keep the admin page url a secret with strong authentication.
However I've ask a friend for his opinion and will continue after that. If you guys have some suggestions comment them, would love to read what you guys have in mind.
