Deconstructing Node.js: An In-Depth Analysis of Architecture, Evolution, and Performance
28 min read • Published on • Last Updated OnNode.js is frequently categorized as a “JavaScript runtime,” a label that, while accurate, fails to capture the sophistication of its design and the profound impact it has had on server-side software development. Conceived by Ryan Dahl in 2009, Node.js presented a radical departure from the prevailing multi-threaded, thread-per-request server architectures of the time. Its core proposition was to leverage JavaScript, a language previously confined to web browsers, for building scalable network applications.The platform’s remarkable performance and scalability do not stem from JavaScript alone but from a unique and deliberate architectural synthesis of Google’s high-performance V8 JavaScript engine and libuv, a C-based library dedicated to asynchronous I/O. This event-driven, non-blocking model was engineered to optimize throughput and scalability for applications with numerous I/O operations, such as web servers, APIs, and real-time communication systems.This architectural model, while powerful, is not without its inherent limitations. The single-threaded nature that makes it so efficient for I/O-bound tasks simultaneously renders it ill-suited for CPU-intensive computations. Over its history, Node.js has undergone a significant and continuous evolution to address these limitations, adapt to a changing technological landscape, and align with the broader JavaScript ecosystem.

The Art of Resilience: A Deep Dive into Exponential Backoff, Jitter, and Modern Retry Strategies
14 min read • Published on • Last Updated OnIn the landscape of modern distributed systems, transient failures are not an exception but an operational certainty. The intricate web of microservices, network links, and cloud infrastructure that underpins contemporary applications is inherently susceptible to momentary disruptions. These can manifest as temporary network partitions, service throttling in response to load (429 Too Many Requests), brief service unavailability during deployments, or ephemeral resource contention on a downstream dependency.

LRU Cache: From Classic Implementation to Modern Alternatives
16 min read • Published onCaching is the unsung hero of high-performance applications. When implemented correctly, it can dramatically reduce latency, ease database load, and create a snappy, responsive user experience. Statistics show that even a one-second delay can cut conversions by 7%. For decades, the go-to solution for developers has been the Least Recently Used (LRU) cache, a simple yet effective strategy for keeping frequently used data close at hand.But what happens when this trusty tool fails? While LRU is a powerful default, it has a critical flaw that can cripple performance under common workloads. This vulnerability has spurred decades of research, leading to a new generation of smarter, more resilient caching algorithms that build upon LRU’s foundation.This guide will take you on a journey from the classic LRU cache implementation to understanding its limitations and exploring modern alternatives. We’ll dive deep into LRU’s inner workings, examine when it fails, and discover how advanced algorithms like LRU-K, 2Q, and ARC address these shortcomings.
