Why Middleware Matters in Modern Go Applications
If you’ve built web applications in Go, you’ve likely encountered a familiar challenge: how do you handle cross-cutting concerns like logging, authentication, and error handling without cluttering your business logic? This is where middleware shines.
I remember working on my first large-scale Go API. What started as clean handler functions quickly devolved into a mess of repetitive code blocks for checking auth tokens, logging requests, and handling errors. Each endpoint became bloated with boilerplate that obscured the actual business logic. Middleware was the solution that helped us regain clarity and maintainability.
