About Basic Middleware in Go
A tutorial blog post explaining the concept of middleware in Go programming, with a practical example using the gorilla/mux router and HTTP Basic Authentication. The post covers how to create a basic authorization middleware that checks credentials before allowing access to protected endpoints, suitable for learning Go middleware patterns.
Key Features
Demonstrates middleware as a layer between router and controllers
Uses gorilla/mux for routing
Implements HTTP Basic Authentication middleware
Wraps handler functions to apply middleware
Shows simple authorization check with hardcoded credentials

Cons
- Limited to BasicAuth with hardcoded credentials (not production-ready)
- Does not cover middleware chaining or more advanced patterns
- No error handling or logging beyond unauthorized response
- Tutorial is brief and lacks deeper explanation of middleware internals

FAQ
What does this tutorial cover?
It covers the basic concept of middleware in Go and shows how to implement a simple HTTP Basic Authentication middleware using the gorilla/mux router.
What packages are used in the example?
The tutorial uses the standard net/http package along with github.com/gorilla/mux for routing.
Is the code from this tutorial production-ready?
No, the example uses hardcoded credentials and is intended for learning purposes only. Production middleware should use proper authentication mechanisms and secrets management.
Can middleware be used for purposes other than authentication?
