Tree-hugger-JS: CSS selectors for JavaScript AST analysis and MCP

I built a library that lets you find code patterns using familiar CSS-like selectors, then connected it to Claude via MCP so AI assistants can understand and refactor codebases. The Approach // Find code patterns with intuitive selectors: const asyncFunctions = tree.findAll('function[async]'); const todoComments = tree.findAll('comment[text="TODO"]'); const reactHooks = tree.hooks(); // Built-in React support // Chain smart transformations: tree.transform() .rename('oldFunction', 'newFunction') .removeUnusedImports() .toString(); Key Features - CSS-like…

    Anyone interested in a tool helps to explore C++ ASTsMay 2026 · uvic-aurora.github.io · ▲49

    I built this software to help users who need to do static code analysis for C/C++ codebase. This can help you to explore the ASTs interactively. It can replace the Clang ast dump completely and also you can search the code/ASTs in a structual way. For example you can search a function which matches specific name or number of paremeters.

    Build progressively enhanced reactive HTML apps using Go and Alpine.js2023 · livefir.fly.dev · ▲127

    Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client…

    I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • Workout.cool – Open-source fitness coaching platform▲827

    I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
