As engineers, we spend a lot of time optimizing our origin servers. We scale them up, add more instances, and fine-tune our database queries. But what if the biggest performance gain wasn't on our origin server at all? What if it was somewhere between our user and our server? For years, the model has been simple: a user makes a request, it hits our infrastructure, we process it, and send a response. This is reliable, but it has limitations. Every request, good or bad, puts a load on our servers. Latency is dictated by the physical distance between the user and our data center. This is where edge computing, specifically with tools like Cloudflare Workers, changes the game. Workers are small, fast functions that run on Cloudflare's global network. They intercept HTTP requests before they reach your origin server. This simple fact opens up a world of possibilities for building faster, more resilient, and more intelligent APIs.…
