This article provides an in-depth examination of rate limiting patterns for large-scale APIs, including token buckets, leaky buckets, quota enforcement, distributed counters, and the systems employed by major platforms such as GitHub, Stripe, Cloudflare, and AWS.
This article delves into the conundrum of out-of-order network responses and the prevention of race conditions in contemporary applications. It outlines patterns for ensuring the most recent request takes precedence using refs, counters, and abort strategies.
This article explores the concept of progressive hydration, a performance optimization technique that prioritizes and defers the loading and activation of JavaScript across user interfaces. We delve into how modern frameworks like Astro, Qwik, and React implement progressive hydration to improve load times and overall application performance.
An in-depth exploration of preloading and prefetching, two potent techniques for augmenting perceived speed by proactively fetching critical resources. Learn to predict user behavior and fetch necessary resources before they’re required, using best practices and browser hints for an enhanced user experience.
A comprehensive technical exploration of polling as a method to maintain synchronization between client UIs and server data. This article delves into short and long polling, their implementation in contemporary applications, performance considerations, best practices, and alternatives such as Server-Sent Events and WebSockets.
This article provides a deep dive into the concept of partial hydration, a performance optimization strategy that selectively activates JavaScript at the component level to achieve faster load times and reduced JavaScript execution in modern frontend frameworks.
This comprehensive guide delves into advanced strategies on how to structure and sequence asset loading in JavaScript applications to prioritize meaningful content. Learn about reducing First Contentful Paint (FCP) and Largest Contentful Paint (LCP) by sequencing the delivery of the right bytes first.
In this comprehensive guide, dive into the concept of optimistic updates, which enhance perceived performance by updating the UI ahead of server confirmation. We will delve into their working principle, appropriate use cases, error management strategies, and real-world applications in popular platforms like Twitter, Noticon, and GitHub.
Optimistic updates provide a powerful approach to enhancing the perceived performance of applications by anticipating successful operations and updating the user interface (UI) before server confirmation. This article delves into the efficient implementation of optimistic updates using React, React Query, and SWR, and discusses how they can significantly improve user experience (UX).
This article delves into the concept of normalized stores in frontend architecture, a technique that mimics database design for predictable, scalable state in large applications. We will explore how Redux, RTK Query, and enterprise applications structure their data to enhance maintainability.
