Connecting the PWA application to the API

I will outsource the PWA application connection to the API

I have a simple PWA application, 3 screens:

1.Screen1, login, entering login and password for the device

2.Screen2, displaying device (air handling unit) data - 5 parameters

3.Screen3, changing the device settings - 5 parameters

I received access and documentation to the API. In short, Authorization by sending a login and password, we receive a token back, which is valid for 7 days. For each subsequent query we add a token and can read and write. Each parameter is one GET/POST query and JSON responses.

Correct entry is to take the user to screen2, every 1sec the application queries the API and displays 5 values.

If the user wants, go to screen3 and change the temperature setting, which is sent to the API. All endpoints will be hardwired.

I will provide more information and access to the project/api to interested parties.
