▶  TypeScript Origins: The Documentary — You know you’ve made it when you get your own documentary! This has just dropped but is well produced, packed with stories from TypeScript’s co-creators, users, and other folks at Microsoft, and kept me entertained. It goes particularly deep into the motivations and process behind its creation, including why Microsoft felt it was worth pursuing.

🔥 The takes get spicer 25+ minutes in as various TypeScript users chip in with their opinions, and even Daniel Rosenwasser, now program manager of the TypeScript team, says he initially worried that Microsoft might “f**k it all up.” 😅 Ryan Dahl pops up about an hour in too.. so I hope you’ve got some time spare.

Patterns for Reactivity with Modern Vanilla JavaScript — When data changes, you often want to do things, and the process that makes that happen is reactivity.

Bun 1.0: Is It a Toolkit? Is It a Runtime? It’s Both — You’ve used Node, you’ve seen Deno, now Bun has grown up too. It’s a performance-oriented server-side JS runtime built atop JavaScriptCore and makes the unique claim of being “a drop-in replacement for Node.js.” It includes extras like transpilation, bundling, package management, and a Jest-compatible test runner too. The post goes into a lot of depth, but we enjoyed the Bun team’s ▶️ 10 minute introductory video. Does Bun deliver on all its promises yet? No. Is it promising? Yes.

🤖 A little JavaScript AI-side..

AI, LLMs and machine learning have caught the imagination of many developers recently, whether through training and deploying models, calling out to third party APIs (like those OpenAI offers), or using tools like GitHub Copilot to write code. It’s common, however, for a lot of AI/LLM experimentation to take place in Python, rather than JavaScript..

Nonetheless, there’s an increasing number of projects in the JavaScript AI/ML space worth keeping an eye on, as well as an upcoming AI developer event being organized by two folks from the JavaScript space:

Transformers.js: State-of-the-Art Machine Learning for the Web — A JavaScript library designed to be functionally equivalent to Hugging Face’s transformers Python library meaning you can run the same pretrained models using a very similar API. You can do things like ML-powered speech recognition directly in your browser using OpenAI’s Whisper model. GitHub repo.

Joshua Lochner et al.

Microsoft TypeChat: An Approach for Type-Safe LLM Responses — Anders Hejlsberg and Daniel Rosenwasser of TypeScript fame are just two of the prominent names attached to this project, demonstrating the huge interest within MS for LLMs. TypeChat’s goal is to work around the issue of LLMs outputting unstructured natural language and to direct output into a typed form.

Hejlsberg, Lucco, Rosenwasser et al.

WebLLM: Run LLM Models in the Browser with WebGPU — Less directly JavaScript, as it uses WebGPU, but yet another way to run large language models directly within the browser and that you can control from JavaScript. GitHub repo.

MLC LLM

TensorFlow.js: Machine Learning for JavaScript Developers — Slightly lower level, but a great way to train and deploy models in the browser or in Node.js. There are, of course, lots of demos, too.

TensorFlow

JavaScript Library Lets Devs Add AI Capabilities to the Web

Loraine Lawson (The New Stack)

▶  A Primer on AI for Developers with Swyx from Latent Space

Svelte Radio

📅 Plus, two JavaScript folks are putting on an AI event..

As part of my interest in AI and ML, I’m attending what promises to be the technical AI event of the year in San Francisco next month: The AI Engineer Summit.

The emerging ‘AI engineer’ category is at the intersection of AI/ML and code: where software engineers can access and implement powerful AI models with just an API. Andrej Karpathy believes that “there’s probably going to be significantly more AI engineers than there are ML engineers / LLM engineers.”

With speakers representing companies like OpenAI, Microsoft, Replit, Vercel, AutoGPT, Adept, LlamaIndex, and Notion, at the Hotel Nikko this October 8-10, the event is organized by two folks well known in the JavaScript world: Swyx (who you may remember from his popular The Third Age of JavaScript post) and Benjamin Dunphy, formerly of Reactathon and Jamstack Conf. You can apply to attend or get a free remote ticket to tune in from wherever you are.

If you’re going to the AI Engineer Summit, I’ll see you there!

JavaScript Weekly

Astro 3.0 Released: The All-in-One Web Framework — An increasingly popular, turbo-charged site generator comfortable with not just static sites, but dynamic and interactive ones too by way of its ‘islands’ approach. You can use React, Vue, Svelte, Solid, and others, with it, and v3 adds View Transitions API support (more on that here) which can result in striking creations like this Spotify ‘clone’. It requires a play to really ‘get it’ but it’s great.

Astro Team

Good news – now SvelteKit supports the View Transitions API too 😉

Node.js 20.6 Released with Built-In Support for .env Files — The official release post covers everything new in 20.6, but the highlight is support for .env environment files to set environment variables dynamically when a script is run without requiring a third-party library like dotenv.

Mozilla: “Over the course of the year Firefox has improved by around 40% on the Vue.js benchmark” – find out why.

David Heinemeier Hansson, the creator of Ruby on Rails, announced that they’re dropping TypeScript from Turbo (a library commonly used with Rails) in favor of plain old JavaScript. Social media drama ensued.

What’s going on with the Gatsby React framework? Folks are noticing there’s not a lot going on with it lately and that 🐦 Netlify layoffs had a big impact. Netlify does, however, say 🐦 updates are coming.

GitHub has made changes to its homepage feeds. Quite a few people are unhappy about it, though.

“The CSS-in-JS sector has plateaued,” says the latest State of CSS survey.

What’s new in Svelte as of September 2023? Quite a lot.

🎉 RELEASES:

TypeScript 5.2 – Complete with the much awaited using declarations..

Node-RED 3.1 – The powerful low-code/visual programming environment gets some key improvements in its editor.

jq 1.7 – It’s not JavaScript, but surely the best JSON processing tool to exist.

Ky 1.0 – Simple HTTP client based upon Fetch for browsers, Node & Deno.

jQuery 3.7.1 – Oh yes indeedy 🎉

Advancing the NodeSource Node.js Package Repo (Including User-Requested Upgrades!)

Posted on by

For over a decade, NodeSource has developed and maintained a Node.js package repository that, has become the standard for production use globally. We are excited to announce some significant updates to this repo that include a large number of items related to user requests. (Note that there is an important point in the section below about using the new repo as the old repo will remain available but no longer be supported with new versions)

We handle over 100 million downloads of the open-source binaries each year, developers rely on our timely releases (fastest in the ecosystem) and tooling to simplify their use of the Node.js Runtime. Every time there is a release, including security updates, our team delivers updates in less than 48 hours.

Img 1- Type of Distributions

As part of our ongoing commitment to the ecosystem, we want to ensure that developers who rely on our repository have access to a robust and efficient resource led by our Node experts. A key objective with this update was to enhance the Node.js package distribution experience, making it more intuitive, feature-rich, and responsive to user needs. In the following sections, we’ll dive into the improvements we’ve made, highlighting the changes that promise to make your development journey easier.

Check it out HERE and let us know your thoughts!

New Features

Version Choice (Made Easy): We have added versatility with the latest update to our repository, gone are the days of being locked into the latest Node.js release. Now, you can choose the specific version of Node.js you need to tailor your environment to the unique needs of your project.

Universal distribution support: Say goodbye to server customization and compatibility concerns. Our repository now seamlessly supports all distributions. You don’t need to adjust for each new OS version, all are supported out-of-the-box.

Seamless CDN transition: We’ve revamped our CDN provider to address cache-related issues. This change ensures a smoother, more reliable experience and eliminates cache-related hiccups..

Streamlined installation requirements: Installing Node.js should be a snap. That’s why we’ve carefully configured the necessary installation requirements. The package now includes the required glibc and Python3 configurations, making the setup more accessible.

Simplified installation process: Recognizing the diversity of our user base, we’ve redesigned the installation process—no more complex scripts to decipher. Instead, we’ve streamlined it to a few simple lines of code. Installation is now easy and accessible for users of all skill levels.

These improvements demonstrate our commitment to providing a repository experience that keeps pace with technological demands and prioritizes user convenience and satisfaction.

⚠️ IMPORTANT: Use the new repository!

Failing to migrate to the new repository could be significant, most notably is the potential denial of access to the latest versions of Node.js. Because these latest versions will be distributed exclusively through the new repository, those who do not migrate will miss important updates, improvements, and features.

For more information on the new repository including details regarding the migration process, we recommend you visit the following link for the repository wiki, which provides comprehensive information on making a successful transition.

Our Distributions Journey

Our mission to help developers gain access to Node.js and enable the enterprise to adopt it safely has been a key driver for our binary distribution effort. We have seen tremendous growth in the number of downloads every year from our distributions across the globe.

Img 2- Request per Country and Data Transfer by Country per 24H

Our flagship product, N|Solid, an enterprise-grade version of the Node.js Runtime, is a testament to this devotion to OSS, and was a key part of why we created this repo that is used by millions of developers to power a massive number of applications. Our Node and Infra experts will continue to support this repo for the community with great pride.

> This repository has seen a staggering number of annual package downloads, over 120 million, and a data consumption rate of around 300 terabytes per month. This endeavor hasn’t been without its challenges, as maintaining such a repository has required extraordinary dedication and effort.

Earlier this year we made the decision to open-source our N|Solid Runtime marking a key turning point for NodeSource, inspiring us to extend our commitment to the repository. (The OSS version of N|Solid will be available in October of this year)

_> Recognizing the symbiotic relationship between Node.js and N|Solid, we decided to merge their paths. _

By distributing Node.js and N|Solid together, we’re creating a unified ecosystem that takes advantage of the power of Node combined with the advancements of N|Solid. This dynamic coupling invites those familiar with our repository to explore what we refer to as “enterprise Node.js,” or the Node.js that enterprises have been waiting for. This synergy is a testament to our commitment to both the Node.js community and the growth of enterprise-grade solutions.

Conclusion

As we embark on this transformative phase, we reflect on our journey in this ecosystem. We’ve been privileged to play a role in supporting developers and companies, and we’re excited to further enhance our collaboration.

Today, we invite you to explore our new repository, HERE, – a hub of choice and compatibility, empowering you to select the Node.js version that suits your needs. But that’s just the beginning of the story. If you are interested in our Enterprise version N|Solid it’s available to you for FREE with additional pricing packages for larger projects/teams and support.

Stay tuned for further enhancements as we refine and enrich your experience.Thank you for being a part of our journey. Here’s to many more years of collaboration and growth!
