This article explains how prop drilling in Next.js applications can be avoided by using Node.js's AsyncLocalStorage to store per‑request context such as requestId, tenantId, and userId, providing code examples, implementation steps, and practical usage tips for clean, maintainable backend logic.
This article explains how AsyncLocalStorage works in Node.js, demonstrates its usage with eggjs, presents benchmark results comparing tegg v3 to earlier versions, analyzes performance bottlenecks, and shows code transformations that reduce memory and CPU overhead for large-scale applications.
The article introduces the TC39 Async Context proposal, explains why asynchronous context is needed, shows a library implementation using run and log functions, describes the AsyncContext API with run, get, and wrap methods, and explores use cases such as trace propagation, task‑priority handling, and comparisons with thread‑local storage and Node.js AsyncLocalStorage.
This article explains Node.js async_hooks and AsyncLocalStorage APIs, describing asynchronous resource concepts, lifecycle hooks, usage scenarios, performance impact, and practical code examples for tracing async call chains, custom async resources, and integrating context propagation in backend applications.
This article explains Node.js’s asynchronous execution model, defines key concepts such as execution frames and continuation points, demonstrates event flow with code examples, and shows how the async_hooks API and AsyncLocalStorage can be used for tracing, debugging, and performance analysis of backend JavaScript applications.
Node.js Technical Committee chair Michael Dawson explains the community‑driven development model, details the four‑type release schedule, highlights upcoming features such as ECMAScript Modules, AsyncLocalStorage and AbortController, and outlines strategic initiatives and working groups shaping the runtime’s future.
Learn how to implement request-scoped data in Node.js by leveraging Async Hooks and AsyncLocalStorage, covering use cases, trace ID management, code examples, and best practices for building robust, session-level isolation in backend services.
