How we built JSR
We recently launched the JavaScript Registry - JSR. It’s a new registry for JavaScript and TypeScript designed to offer a significantly better experience than npm for both package authors and users: It natively supports publishing TypeScript source code, which is used to auto-generate documentation for your package It’s secure-by-default, supporting token-less publishing from GitHub Actions and pa
JSR: the JavaScript Registry
JSR is designed for TypeScript. You publish TypeScript source, and JSR handles generating API docs, .d.ts files, and transpiling your code for cross-runtime compatibility. JSR packages are distributed as web-standard ECMAScript modules. JSR isn't a replacement for the npm registry; it's a superset of npm. JSR modules can be used with any JavaScript package manager, and in any project with a node_m

Introducing humanfs (formerly fsx): A modern filesystem API for JavaScript - Human Who Codes
The JavaScript APIs we have today are so much better than those we had even a decade ago. Consider the transition for XMLHttpRequest to fetch(): the developer experience is dramatically better, allowing us to write more succinct, functional code that accomplishes the same thing. The introduction of promises for asynchronous programming allowed this change, along with a series of other changes that
A Gentle Introduction to Islands
Modern JavaScript frameworks include a lot of JavaScript. That’s kinda obvious. But most web sites don’t contain a lot of JavaScript. Some do. If you’re building a dynamic interactive dashboard, JS your heart out. On the other end, documentation pages, blogs, static content sites, etc. require 0 JavaScript. This blog, for example, has no JS. But then there’s this whole horde of websites in the mid
Sandboxing JavaScript Code
I've been enjoying playing around on Val Town lately. Val Town can be described a few ways; a cloud scripting site, a runnable github gists, or end-programmer programming. I first came across it in a Show HN thread. A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule
Will Bun JavaScript Take Node's Crown
Huge thanks to Jarred Sumner for reviewing this post. It wouldn’t have been possible without his help. Bun is a new and ambitious JavaScript toolset and runtime. Early adopters have been reporting that Bun JavaScript is incredibly fast. So fast that it has been touted by some as a Node.js killer. Curious, I decided to check out Bun for myself and benchmark it against the competition. Is it as fast

Interview with Ryan Dahl, Node.js & Deno creator by Evrone
In an interview with Evrone, Ryan Dahl speaks about the main challenges in Deno, the future of JavaScript and TypeScript, and tells how he would have changed his approach to Node.js if he could travel back in time. Introduction Ryan Dahl is a software engineer and the original developer of the Node.js, and the Deno JavaScript and TypeScript runtime. We are glad to have had an opportunity to speak
ESM>CDN
Create modern(es2015+) web apps easily with NPM packages in browser/deno.No build tools needed!import confetti from "https://esm.sh/canvas-confetti@1.6.0" esm.sh is a modern CDN that allows you to import es6 modules from a URL: import Module from "https://esm.sh/PKG@SEMVER[/PATH]"; or build a module with custom input(code): import { esm } from "https://esm.sh/build"; const { render } = await esm`
