No language is immortal—Node.js isn’t either—but thoughtful reflection is priceless. This underground community for Node.js enthusiasts was started by Taobao’s Front‑End Team (FED) to share our original insights and viewpoints from working with Node.js. Follow us. BTW, we’re hiring.
V8 Lite, introduced by the V8 team in late 2018, implements a series of memory‑saving techniques—such as lazy feedback allocation, delayed source positions, and bytecode flushing—that together can reduce heap usage by roughly 22% in memory‑constrained scenarios while maintaining acceptable execution performance.
This article explains how JavaScript Proxy can intercept object operations to implement getter/setter shortcuts, dynamic validation, logging, and flexible API proxies, providing clear code examples and practical scenarios for both front‑end and Node.js development.
This article recaps a hardcore Node.js underground salon where experts explored runtime optimization, V8 engine enhancements, Alinode monitoring, fork(2) performance tricks, and core startup processes, highlighting practical insights for Serverless, IoT, and high‑performance backend development.
This article explains the architecture of Node.js, the limitations of its single‑threaded event loop for CPU‑heavy workloads, and how the experimental worker_threads module provides a multi‑threaded solution, including core concepts, APIs, best practices, and sample code to improve performance.
This article explains Node.js's CommonJS module system, covering how require loads modules, the role of module.exports versus exports, module classification, loading order, caching behavior, circular dependencies, and provides practical code examples for interview preparation.
This article showcases an obscure JavaScript expression built from the characters ()+[]! that, when run in a browser, produces the same result as alert(1), and explains its origin on the Esolang Wiki and a popular GitHub repository.
This article demonstrates several modern Node.js capabilities—including optional catch bindings without parameters, whitespace trimming methods, accessing Symbol description strings, flattening arrays with flat and flatMap, handling Unicode in JSON serialization, and converting entry lists to objects with Object.fromEntries—providing concise code examples for each feature.
This article introduces Node.js by covering its origins, core architecture, key features such as event‑driven non‑blocking I/O, and the scenarios where it excels, helping readers decide when and why to choose Node.js for backend development.
This article explains how Node.js 12 introduced native ECMAScript Modules, compares them with CommonJS, shows how to enable the feature, configure package.json, and adapt code using import/export, import.meta, and other module‑specific changes.
This article explains the background, implementation, and practical usage of V8's code cache in browsers and Node.js, showing how serialized bytecode reduces JIT compilation overhead, speeds up startup, and benefits serverless functions.
