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.
An interview with Red Hat engineer Bethany Griggs reveals how Node.js 15 addresses security, error handling, and future priorities while responding to Ryan Dahl’s criticisms that inspired the Deno runtime, highlighting the platform’s role in cloud‑native microservices and server‑side JavaScript.
The article reviews the latest TC39 meeting, detailing proposals that moved to higher stages—including Error Cause reaching Stage 4, Intl.DisplayNames enhancements, Import Assertions, .item() for indexables, class static blocks, resizable array buffers, Intl.Enumeration, double‑ended iterators, integer math extensions, standardized debug syntax, String.dedent, Intl.Locale, and DisplayNames v2—while outlining the criteria required for each stage transition.
This article recounts a real‑world incident where a simple JSON.parse() try‑catch block triggered a massive memory leak in a Node.js 12 application, explains how the V8 engine’s script_list retained orphaned script objects, and shows how tools like gdb, llnode and heapdump can be used to locate and fix the issue.
This article details the Midway Serverless framework's cloud‑native, React‑Hooks‑inspired approach to backend development, covering Alibaba's Node.js serverless landscape, the framework's architecture, new integrated development model, functional R&D features, and future open‑source plans.
This article explains how Node.js child_process stdio options, pipe handling, and stream events interact, why unconsumed output can block a child process, and provides step‑by‑step experiments and debugging techniques to avoid deadlocks.
This article introduces the Hey load‑testing tool, explains how to install and run it with specific QPS settings, analyzes the resulting metrics and charts, and offers practical tips for identifying bottlenecks such as network bandwidth or CPU usage during capacity planning.
This article explains Midway Serverless's core capabilities, design principles, anti‑corrosion architecture, toolchain, and migration workflow, showing how a single codebase can run unchanged across multiple cloud platforms while simplifying legacy application transition to serverless environments.
Midway Serverless v1.0 introduces a universal anti‑corruption layer that lets traditional EggJS applications be deployed to various cloud platforms with minimal code changes, offering a unified runtime adaptation, migration workflow, and outlining its advantages, limitations, and usage example.
Node.js’s single‑threaded model relies on an asynchronous continuation framework, and this article explains the core concepts—execution frames, continuations, link points, ready points—and how async_hooks, AsyncLocalStorage, and related APIs can be used to trace, debug, and ensure clean async task handling in backend applications.
This article explains how Alibaba's Midway Serverless framework reduces server and governance costs by up to 70%, accelerates front‑end development and deployment, and addresses the benefits, challenges, and operational impacts of adopting a serverless, cloud‑native architecture.
