How can I prevent multiple requests from rapid button clicks in my app?

During a technical interview, I faced a similar question. One solution that was used in production was changing the request type from POST to GET after the initial click. It can help manage how the calls are made.

A simple way to handle this is to add a loading state to your button. Disable the button once it's clicked, and keep it disabled until the request finishes. This way, you stop the spam clicks without needing complex logic.

You could also modify your backend to ignore repeated requests from the same user or session within a certain timeframe. This way, even if the button gets clicked multiple times, only the first request will be processed.

Check out the concept of 'debouncing'—it's a great technique to limit how often a function gets called. Basically, it allows you to set a delay between requests, so rapid clicks don't overwhelm your API.

Consider implementing throttling on your backend. There's a good resource here on throttling patterns: [Throttling Patterns](https://learn.microsoft.com/en-us/azure/architecture/patterns/throttling). It can help manage how many requests a user can make in a given time.
