I'm developing an e-commerce platform with React on the frontend and Deno (using Hono) for my backend as part of a personal project. My main issue is figuring out how to cache a large number of GET requests from customers since the frequency of changes in the database is relatively low. What are some effective caching strategies typically used by e-commerce sites?

Have you considered using Deno KV for caching? Just a heads up, though – caching is not the same as database storage. If you're looking for performance, ensure you're using an in-memory database designed for caching specifically. Regular databases can be too slow for caching purposes.
A CDN might be what you need! Services like Cloudflare or Fastly can sit in front of your API and manage responses efficiently. They can drastically reduce the load on your Deno backend.
Start with setting appropriate `Cache-Control` headers on your Hono API responses, especially for product data; even just a few minutes can help. Additionally, consider implementing a CDN like Cloudflare to distribute your content and lighten the load on your server. For client-side, React Query is fantastic for handling caching without causing unnecessary re-fetching of data.
React Query is definitely worth looking into! It works great for managing client-side caching. Just be cautious with caching user-specific data, but you can cache static lists without any issues.
