Error Handling in API Requests

[runeharlyk]

Problem

Currently if a request fails the end user does not get notified of the result of the request. Most fetch call is wrapped in a try catch that silently logs the error with console.error().

Proposal

An api service, which handles the unsuccessful requests and return a typed response. Something like:

await get<Networks>('/rest/listNetworks')

The service should:

• Fetch the data with appropriate authentication
• Notify the user (maybe via toast service) of any errors that occurred
• Cast the json response to T type
• return the data

Let me know if you are interested in the proposed feature.

I'm not a professional developer and used this project to learn JS/TS. So yes, there is a lot to improve.

I would also be interested in a more graceful behavior of the front end when the connection to the ESP is lost temporarily, or the ESP restarts.
