I’ve been experimenting with lightweight browser games like word puzzle online that update daily content. I’ve noticed some performance inconsistencies—sometimes the puzzles load slowly, and on certain devices the input validation feels delayed. I’m wondering what the best approach is to manage daily-updating content in a web app so it performs consistently across different browsers and devices. Are caching strategies, service workers, or some other optimization techniques the way to go here?

Hi Maci,
For daily-updating games the main thing is to make a clear split between the static assets and the puzzle data. Static files like your scripts, styles, and images can be cached heavily and ideally served from a CDN so they load instantly on repeat visits. The only piece that needs to refresh each day is the puzzle data.
A service worker is a good option for this. It lets you cache the game shell locally so the app feels fast, then fetch the latest puzzle content in the background. If you’re pulling the puzzle from an API, you can set caching headers so the data expires after 24 hours, which matches your daily update cycle.
For the slower input validation, keep the logic as light as possible on the client. If you need heavier checks, consider debouncing or running them less frequently so the user doesn’t feel the delay.
You can find a guide on setting up a CDN with DigitalOcean that might help with speeding up your static content. For the service worker side, MDN has a solid intro to service workers: https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API/Using_Service_Workers
