The HTTP Request Journey in Go: From Network to Handler

Fri, 08 Aug 2025 10:00:00 +0000

As a backend guy, I’ve been tasked with building various APIs for different projects, and most of them I built using Go. For the majority of the time, what most people do is write a handler or middleware to process and respond to requests. Today, we’re going to do something different. We’ll go down a rabbit hole together into the abstractions that Go has taken away from us. We’ll see all the interesting things that Go does before handing us the request and response objects in our handler. After this deep dive, we’ll understand how to parse requests, how routing matching works, middleware execution, and finally the architecture that Go uses to handle each request.
