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…

A FOSS chrome extension that attempts to remove the annoyance of cookie pop ups and banners. There are some extensions out there that auto-accept cookies, but I didn't find one that auto rejected cookies without either chaining some extensions together or setting up custom rules in tools like uBlock origin. So with this extension, you just need to add it for non-essential cookies to be rejected.

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.

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.

Hello HN! A few days ago I saw a comment on reddit which proposed a service that allowed the user to spam a website's server logs with messages objecting to the presence of various anti-features like popups, noisy ads, and autoplaying content. The idea tickled my fancy, so I've put together a Chrome extension which detects if a page is using Google Analytics, and if so it injects a small script which sends bunk utm (urchin tracking module) data to the GA backend. It sets the traffic source to "DO NOT WANT!", and the campaign name to various things like "I do NOT want noisy ads!" Here's the…

Hey all - we decided to build an open-source (https://www.github.com/swishjam/tagsafe) tool to self-host and version control all of your third party javascript on your website's frontend. What's the problem with third party javascript? Honestly, there's quite a few issues. Here are some of the most relevant ones: 1. You don't have control over what the 3P JS does on your site or when updates are made to it. With each 3P tag added to your site, you give the ability for someone else to push changes to your site without your knowledge or control. 2. There are lots of…

Hey all, Andy from the Deno team here. We're excited to share with you Deno Subhosting, an easy way to extend your platforms functionality by securely running untrusted JavaScript written by your users. When we first launched Deno Deploy in 2021, we were surprised at the volume of requests from companies about getting access to the APIs needed to run Deno Deploy. Many companies wanted to give their users the ability to write custom logic in their app, but setting this up in the cloud presents security concerns and a ton of infra work/maintenance. We realized that there was an…

This is a Node.js script that leverages Puppeteer with extra settings to create a web crawler that avoids detection. This tool allows you to scrape websites while minimizing the risk of being blocked or identified as a bot.

I recently saw a post from the Vercel CEO pointing out that LLMs understand websites much better when they can request: `Accept: text/markdown` Most websites today are built for humans. When AI agents try to consume them, they get complex HTML instead of clean, structured content. So I built *accept-md* – a simple open-source package for Next.js that helps solve this. Getting started is intentionally minimal: ``` npx accept-md init ``` After that, your existing Next.js routes can automatically respond with Markdown whenever an AI agent (or any client) requests it. No redesigns, no CMS…

I've launched the new product, xhr.dev (https://xhr.dev/) The initial product is a 1 line code integration that does bot detection avoidance via a forward proxy. Ideal customer is someone who gets blocked by anti-bot defences like cloudflare or other captcha challenges. Usually these customers have web scraping use cases. You can view our historical performance on our status page (https://status.xhr.dev). ty v much, john

This is a browser front-end (ultra simple) for Chrome, built using puppeteer. I like it because it provides a usable single browser tab (that conveniently crashes on certificate errors (thanks to puppeteers default flags which I haven't altered here)), without using any JS scripting on the client side. There's some clever hacks to get that to work, including stylesheet media queries (to zero in on the correct viewport dimensions), and MJPEG, a crazy HTTP keep-alive way to stream JPEG frames of a video, favored by old-style CCTV/security/web cameras allegedly. I noticed it went from…
