Rust async microservices: rate limiting, backpressure, batching and middleware

Rust Async Microservices, Tamed: Rate Limiting, Backpressure, Batching, and Middleware

Bold claim up front: stability is not “slow.” Stability is making “fast” happen in an orderly way. With the gates placed at the right spots, even a flood can be channeled into rivers. Think about a subway during Monday rush hour. Entry turnstiles regulate inflow, platforms enforce headcount, trains add extra cars, and the PA system orchestrates everything. That is exactly what microservices must do under high concurrency. Your Rust service needs the same four gates: rate limiting, backpressure, batching, and a smart brain of middleware. ...

Node.js Middleware Optimization Architecture Diagram

The Middleware Optimization Trick That Made My Node.js Server 40% Faster

Have you ever been in this situation: your Node.js server is getting slower and slower, users are complaining about page lag, but you don’t want to undertake a massive rewrite of your entire project? Don’t panic! Today I’m sharing a “lazy but effective” optimization approach—middleware refactoring. Using this method, my server performance improved by 40%, and the code became cleaner too. What is Middleware? Let’s Get This Concept Clear First Simply put, middleware is like a restaurant server. You order a dish (make a request), the kitchen prepares it (processing logic), but before the dish reaches your table, the server has to do many things: ...

Build a high‑performance Web server with Rust and Axum

Rust + Axum, from zero to hero: build a high‑performance Web server the LEGO way

You’ve heard the rumors: Rust is blazing fast and memory‑safe, but writing backend services feels intimidating. What if it could feel like building with LEGO — intuitive, composable, and fun? Enter Axum, a modern Web framework built by the Tokio team. In this tutorial you’ll: Understand Axum’s core concepts: Router, handlers, extractors Work with path parameters, query parameters, and JSON Add shared state with Arc<Mutex<T>> Install middleware such as structured tracing Step 1: Add dependencies axum = "0.7" tokio = { version = "1", features = ["full"] } Or via CLI: ...
