Hi everyone! I have a question about best practices. I have a typeahead input on my website. When the user types in, I make a query to get him a list of cities. Right now, I make a query every 500ms, but I don't know if it can be too much for my backend. My question is, what would be the best practice for this? Limit to a query every second? thanks!

Hi To avoid a huge cost on your backend, you can limit requests with 3 characters minimum. So if the input length is less than 3, you don't start to find anything.

Yes ok that seems a good idea, thanks! I was also thinking maybe caching results from previous requests in local storage for like an hour or something, but maybe that's overkill...

You can, it optimizes a little more
