🗓️ Friday is the new Thursday! If you were a JavaScript Weekly reader several years ago, you might remember it always landed on Fridays and after getting caught out by a variety of big news items landing on Thursdays in recent years, we’re back 😉 __ Your editor, Peter Cooper

⭐2024’s JavaScript Rising Stars — It’s time to fully wave goodbye to 2024, but not before Michael Rambeau’s annual analysis of which JavaScript projects fared best on GitHub over the past year. Even if you dislike GitHub stars as a metric for anything, this remains a great way to get a feel for the JavaScript ecosystem and see what libraries and tools have mindshare in a variety of niches. A fantastic roundup as always.

A Look at Import Attributes — It’s always a pleasure to see Dr. Axel blogging about JavaScript again, and he’s back with one of his typical deep dives into a newer ECMAScript feature: import attributes. This feature provides an inline syntax for attaching metadata to module imports such as for importing non-JavaScript modules (e.g. JSON, WASM or CSS).

Node’s New Built-in Support for TypeScript — Node.js v23.6.0 (Current) has just been released and makes Node’s new type-stripping features work by default, so you can just run node file.ts and it Should Just Work™. Dr. Axel explains how it works and what the limitations are.

IN BRIEF:
🥊 The Deno vs Oracle fight over the JavaScript™ trademark continues as Oracle has informed Deno they’re not going to voluntarily relinquish the mark. Deno’s job now is to show how JavaScript has long been used as a generic term and hasn’t been controlled by Oracle.
❄️ The ‘WinterCG’ Web Interoperable Runtimes Community Group, an effort to promote standards around runtime interoperability of JavaScript runtimes, has moved to Ecma International and is now known as WinterTC (TC55).
📺 Node.js creator Ryan Dahl gave a talk at GOTO Chicago 2024 about Deno 2, covering Deno’s differences to Node and what Deno 2.0 (and JSR) has to offer JavaScript developers, complete with live demos.
RELEASES:
pnpm 10 – The efficient npm alternative no longer runs lifecycle scripts of dependencies for security reasons, hashing algorithms have been upgraded to SHA256, and lots of minor tweaks.
Bun v1.1.43 – The high-performance runtime gets first class S3 support, an HTML bundler, and can output V8 heap snapshots (which is quite something as Bun uses JavaScriptCore, not V8).
🔠 Tesseract.js 6.0 – The popular pure JS multilingual OCR library has resolved a variety of memory leak issues.
Docusaurus 3.7 – The popular docs-oriented site generator goes full React 19.
The Future of htmx — htmx is an increasingly popular way to enhance HTML and actually write less JavaScript on the frontend. This post reflects on how htmx would like to be ‘the new jQuery’, not least in the sense that one of the project’s goals is to push the ideas of htmx into the HTML standard itself, as in this set of proposals.

You Don’t Need Next.js — As much as Next.js is considered the React meta-framework of choice, if your requirements are modest, simply going with plain React offers numerous benefits in terms of simplicity and speed, as seen here.

Using TypeScript Without Build Tools — Chris Coyier enjoys the benefits of TypeScript while developing, but actually compiling it to JavaScript in various scenarios is less endearing. We’ve learnt (above) that Node can now run .ts files directly, but what other projects support the use of TypeScript without build tools?
I’ll let you decide if this one is fun or frightening! Whether or not this will work depends on your PDF reader or browser support, but it works with Chrome and Firefox, at least.
The PDF document format supports embedded JavaScript and this experiment uses it to implement a game of Tetris. The developer, Thomas Rinsma, has used Python to output the PostScript that includes the game’s JavaScript. Couple that with the fact many browser PDF renderers are themselves implemented in JavaScript (e.g. PDF.js) and you have a veritable Matryoshka doll of technologies at play here.
