The implementation of polling has been done to simulate a real-time experience. Since this is a realtively low-load scenario this approach was fine. But for cases where it falls short because of factors like really low-latency requirement or server load, implementing web sockets or long polling or SSE would work better depending on the use-case.
- Another side effect of polling that could be improved is an exponential backoff, where if an API call fails then the subsequent API call would only be made after delay * 2. This would help reduce hitting the server unnecessarily if there ever is an outage.
An authentication service would improve user experience and be able to dynamically sign in - currently this is hardcoded since the requirement just was to login.
