Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

Author here. I really love the programming paradigm behind by Phoenix LiveView applications and wanted to expand the ecosystem to include programmers like myself that love Typescript. In summary, LiveViewJS reuses all the Phoenix client code and implemented a new backend in Typescript to handle client events and send back updates. Lots more detail and examples in the repo. Would love any questions and/or feedback. Thanks!

I needed a way to let users write JavaScript to create plugins for a site I'm building. I couldn't find a solution I was happy with, so ended up building one that run's it in a web worker on a separate domain from your main site. Hopefully I haven't missed anything. If so, please let me know! My website has an interactive demo you can write code in the browser textarea, and see the output on the right.

About a year ago, I stumbled upon a new Nodejs language called "Imba", I found this language to be interesting and it seemed like it had a lot of potential. Doing a bit of digging, I realized no one had created a framework for it, so what did a normal dev do? Well, a normal dev went ahead and created another Nodejs Framework, only this time it was meant for Imba. So what did I create? I created a batteries included Framework heavily inspired by Laravel but it runs on Nodejs, and uses Imba as the default language, but you can actually use TypeScript or JavaScript. In fact, when creating a new…
