We can confidently say that multithreading is a game-changing addition to the WebAssembly spec, considering all that it has enabled us to do, like creating a Node runtime that runs on the Web. Moreover, as we have said before, the Rust tooling around it is (generally) excellent. We borrow liberally from the crates ecosystem, and being able to just pull, say, parking-lot and use it out of the box in your project feels like holding fire in your hands. However, we have also mentioned in the past how we frequently run into the limitations of the current state of affairs. We recently encountered a particularly nasty one that we had to go ah

In 2021 we announced WebContainers, a novel WebAssembly-based operating system which enables Node.js to run entirely inside the browser. Over the last two years, millions of developers have used WebContainers each month as it powers, among others, the StackBlitz editor. Today we are thrilled to release the WebContainer API for public use and we invite the entire JavaScript and Node.js community to build your own applications on top of WebContainers with us! We built the StackBlitz classic editor, Codeflow IDE, and Web Publisher: we can’t wait to see what you come up with! Get started over at

Some of these are quick one-off experiments, some are tended to and long-lasting. In many cases a single project doesn't cut it. It might be the need for usage examples of a specific library, a group of demos for a workshop or a conference talk, or a set of presets for bug reproductions. Today we are announcing a way to organize such projects into Collections!

This article was written based on our development collaboration with Evil Martians. You can check their technical blog. In this article, I'll tell you a little story: I added an automated caching mechanism to Octokit …and everything went wrong. Thanks to my fantastic misadventures, you'll learn about HTTP caches, how Faraday middleware work, and how to use them to automagically start caching API calls. I was beginning to get very tired, sitting by my computer on the bank, manually caching API responses. Once or twice I peeped into RFC 7234, but it had no pictures or conversations in it, "and what is the use of a document", I thought, "without pictures or conversations?" But seriously, everything started with

Vite has quickly become the epicenter of innovation in web development. It now powers nearly all major frameworks including Svelte, Vue, Nuxt, Astro, and Shopify's Hydrogen—the first production React framework to natively support React Server Components. Last year StackBlitz became the largest backer of Vite core development. While working with this ecosystem we've become incredibly excited about the progress and collaborations happening. We felt this community's work deserved a dedicated spotlight. That's why today, we are excited to share that StackBlitz is hosting the first ever ViteConf: a celebration of the open web ecosystem, and unveiling a new era of truly instant web development. ViteConf is entirely free and happening live online on 11-12 October. Together with Cloudflare and Netlify, our Co

The conference season has officially begun with StackBlitz getting major shoutouts at OpenJS World and the JSNation Conference. For us it was also a month of two alpha releases: Firefox support and WebContainers API. We are on the roll and we are not stopping any time soon!

Two days ago we announced that WebContainers are now compatible with Firefox. In fact, we soft-launched the alpha version a few weeks ago! We've been working hard for the past months to make this a reality, and we can honestly say that has been both trying and rewarding. Seeing a full Node runtime run on a new browser was well worth the effort, but it's had us toiling down some pretty deep rabbit holes. You see, WebContainers are not your run-of-the-mill web application. We don't render any UI, nor do we have any CSS code. We don't run into the "usual" cross-browser problems with rendering differences. Instead, we make heavy use of message passing, WebAssembly and atomics. We need to pay attention to the precise wording of Web specs and Node's documentation, so we get the behav
