Bare: A New Lightweight Runtime for Modular JS Apps — Imagine something like Node.js but really stripped back: bare, if you will. Like Node, it’s built on top of V8 and libuv, but Bare’s approach is to provide as little as possible (a module system, addon system, and thread support) and then rely upon userland modules that can evolve independently of Bare itself. It’s...

Land Ahoy: Leaving the Sea of Nodes — A deeply technical post from a core member of the V8 JavaScript engine team that explains the limitations of Turbofan, one of V8’s optimizing compilers. If you don’t care for the internals of how your JavaScript is compiled and run, just be assured the V8 team is working to make it run even faster!

Express 5.1: Express 5 Finally Becomes the 'Latest' Release — After a period of some dormancy, Express 5.0 was released last year, but remained a somewhat experimental ‘edge’ release as it went through a security audit and process of building up new governance. With 5.1, however, Express 5.x finally becomes the ‘latest’ tagged release on npm, so be careful with those upgrades (luckily there’s...

Neutralinojs 6.0: Alternative Cross-Platform Desktop App Approach — Neutralinojs offers an interesting lightweight alternative to something like Electron, as it still lets you build apps that run on Linux, Windows and macOS, but Chromium isn’t bundled – instead the existing installed browser engine is used.

Playwright MCP: Connect LLMs to Browsers with Playwright — MCP (Model Context Protocol) servers enable certain LLM-based agents (such as Claude Desktop, Claude Code, and Cursor) to perform actions on systems outside of their usual sandbox. This new project from Microsoft enables such LLMs to interact with Web pages via Playwright.

Node v20.19.0 (LTS) Released with require(esm) — Node v20 is in maintenance mode, which usually means no new features, but it lands a significant one here: support for require(esm) enabled by default. This means all Node v20+ releases now support loading native ES modules with require out of the box. Ideal if you have dependencies to update and you’re still on v20.

Node v23.10.0 (Current) Released — Node gains a new --experimental-config-file option for writing a JSON-based config file that contains options that would otherwise litter your command line flags – ideal for configuring the test runner, say.

Node.js Gets an Official Community Space on Discord — While there have been numerous IRC channels and Discord and Slack servers where Node developers can congregate, the Nodeiflux Discord server has been promoted to being an official one – here’s the invite link if you’re a Discord user. There are already 15k members, so it’s hopping.

🔎 Node Modules Inspector — A tool that runs pnpm inside your browser, “installs” a package, then analyzes its dependencies. This can be useful for analyzing packages you already use, but also for simplifying your own projects, as 11ty’s Zach Leatherman did here.

Node Added TypeScript Support, But What Does That Mean for Deno? — The Deno team, learning from previous experiences with Node, went ‘all in’ with TypeScript from day one. Now, Node can work with TypeScript too, but the experience is still very different, and the Deno team explains how here.

Turbocharging V8 with Mutable Heap Numbers — The V8 team uses the JetStream2 benchmark suite to investigate performance issues and has implemented a new optimization yielding not just a 2.5x improvement in the async-fs benchmark but in other areas too. A demonstration that not only does the Node team make Node faster, the V8 team does too.

InversifyJS 7.0: Inversion of Control Container — A lightweight inversion of control (IoC) container to help you adhere to OO best practices.

Web Scraping with Playwright — I’d be surprised if you got away with scraping YouTube like this for long (let’s say Google aren’t big fans of the approach) but the techniques demonstrated are useful more generally too.

Announcing TypeScript 5.8 — Four months in the making, TypeScript 5.8 lands with a strong Node focus. You can now use require() for ES modules in the nodenext module, there’s a new node18 module for developers who want to keep targeting Node 18, and most notably there’s now an --erasableSyntaxOnly option to ensure no TypeScript-only runtime semantics can be used (ideal if you’re using...
