About the episode

In this video, we dive into rate limiting in Golang, a crucial technique for protecting APIs from abuse, ensuring fair resource allocation, and preventing excessive traffic from overwhelming your server. We'll use the golang.org/x/time/rate package to implement a token bucket-based rate limiter.  

🔥 What You'll Learn:
✅ What is rate limiting and why it matters for APIs  
✅ How to set up a simple HTTP server in Golang  
✅ Implementing a rate limiter middleware using the rate package  
✅ Limiting requests per IP address using a map-based approach  
✅ Handling excessive requests with HTTP 429 (Too Many Requests) responses  
✅ Running a test client to observe rate limiting in action
