I made a CLI tool to create web extensions with no build configuration

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…

In plain words

Extension.js is a CLI tool for building browser extensions that requires no build configuration. It supports TypeScript, WebAssembly, React, and modern JavaScript out of the box. Developers can create cross-browser extensions by adding the package to npm scripts and running a single command, eliminating the need to learn new frameworks or manage complex setup processes. The tool is designed for web developers building browser extensions.

    Hey HN, I'm Alex, founder of Interval [0]. We’re bringing internal tools written like CLIs to the browser to make them more powerful, through a Node.js SDK which attaches them to a hosted dashboard without any frontend code. Large companies have full teams that work on internal dashboards and tooling. Interval brings that infrastructure to anyone. In our previous project we had ~65 CLI scripts for tasks like provisioning user accounts, moderating content, and migrating data. These were quick to write and powerful. They also turned into an ongoing timesuck. Non-technical coworkers needed to…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
