multicast-stream: Create a Multicast Stream Multiple Consumers Can Use Independently — We get two new libraries from Sindre this week. This one is a multicast stream that lets multiple consumers independently read the same data.

Light My Request: Fake HTTP Injection Library — Injects a fake HTTP request/response into a Node HTTP server for simulating server logic, writing tests, or debugging. Doesn’t use a socket connection so can be run against an inactive server (server not in listen mode).

yocto-spinner: Tiny Terminal Spinner — Fresh from the one-man module powerhouse that is Sindre Sorhus comes a new project: a tiny, as simple-as-possible terminal spinner/progress control. (‘Yocto’ is a metric prefix that sits below nano, pico, femto, atto, and even zepto..)

google-spreadsheet: Google Sheets API Wrapper for Node — Work with Google’s online spreadsheet from Node, whether at the cell, row, worksheet or document level. Supports numerous auth options and you can export sheets for download too. GitHub repo.

Node v22.8.0 (Current) Released — This landed just before we hit ‘send’! :-) The enhancements are minor, but there are a few, including a new API for enabling on-disk code caching of modules (rather than using the NODE_COMPILE_CACHE env var) and a way to set required thresholds for code coverage measurements.

Multithreaded Programming in Node.js using Atomics — Worker threads enable you to write multi-threaded Node apps, but sharing resources across them can quickly become tricky. Atomics can help you avoid some of the pain.

▶  Talking Deno 2 with Ryan Dahl — A chat with Deno creator Ryan Dahl (originally Node’s creator too) about the forthcoming Deno 2.0, its new features, and how it seamlessly integrates with popular frameworks like Next.js. Ryan shares insights on the motivations behind Deno’s creation, its emphasis on simplicity and security, and offers his take on the evolving JavaScript ecosystem.

How to Deploy Node to AWS Lambda with OpenTofu and GitHub Actions — Someone on Hacker News joked that this is how to deploy a Node.js app enterprise-style. A lot of tooling is involved, but this is the reality for many developers, and Meysam walks through the steps.

▶  Behind the Scenes: The Making of VS Code — A detailed conversation with two of the principal engineers who work on the engineering team of the popular Electron-powered editor.

Developer’s Guide to Heroku Dynos — Which dynos should you use, and how many? (TLDR: Don’t use Perf-M!)

N3.js: Fast, Spec-Compliant, Streaming RDF Library — RDF (Resource Description Framework) is a long standing mechanism / format for modeling and specifying Web resources and this library works in Node and browser alike.

How to Create an NPM Package in 2024 — Sounds simple, but there are a lot of steps involved if you want to follow best practices, introduce useful tools, and get things just right. Matt Pocock walks through the process here, and there’s a 14-minute screencast too, if you’d prefer to watch along.

Node v22.7.0 (Current) Released — Node 22.6 let you strip types from source code, but now with --experimental-transform-types you can transform TypeScript-only syntax into JavaScript before running it too. Module syntax detection is now also enabled by default.

sqlite-vec: A Vector Search Extension for SQLite — If using a dedicated vector storage database is beyond your immediate requirements, you can now use SQLite for the task. While this is an SQLite extension, it’s easy to use with numerous languages and runtimes, including Node.js, as shown here.

Node v20.17.0 (LTS) Released — The LTS release of Node gains some backports, including support for using require for synchronous ESM graphs (using a flag), matchesGlob, and duplexPair.

Regexes Got Good: The History (and Future) of Regular Expressions in JavaScript — Regular expression support in JavaScript was always a little underwhelming, but things have improved a lot in recent years. Steven takes us on a tour to refresh our knowledge.

▶  Node.js Evolves — Discussion on new Node.js features including native TypeScript support, SQLite integration, dotenv support and more.

npm-check-updates 17.0: Update package.json Dependencies to Latest Versions — That is, as opposed to the specified versions. It includes a handy -i interactive mode so you can look at potential upgrades and then opt in to them one by one.

html-metadata 2.0: HTML Metadata Scraper and Parser — The Wikimedia Foundation’s library for extracting metadata embedded within HTML, such as Schema․org data, Dublin Core, JSON-LD, Open Graph, meta tags, title tags, and the like.

wait-on 8.0: Tool & Library to Wait for Ports, Files, and Sockets — For when you need to wait until files, ports, sockets, and similar resources become available (or the opposite).

Node v22.6.0 (Current) Released — v22.6 landed hours after we sent the last issue, but remains the latest Current release. It introduced the new type annotation stripping feature (via --experimental-strip-types) as well as experimental support for network inspection.

LogTape: Simple Logging Library with Zero Dependencies — I’m digging this new style of library that promises support across all the main runtimes (Node, Deno, Bun) as well as edge functions and browser devtools.

Common Causes of Memory Leaks in JavaScript — Filled with basic examples oriented around V8-based runtimes like Node.js and Deno.

Puppeteer Adds Official Support for Firefox — As of version 23, Google’s originally Chrome-only Puppeteer browser automation library has first-class support for Firefox too.
