Lints your code against Web Baseline features, blocking unsupported APIs in PRs and guiding safe modern usage - via GitHub Action or CLI.

Lints your code against Web Baseline features, blocking unsupported APIs in PRs and guiding safe modern usage. - ej-sanmartin/base-lint

Base Lint is an open-source toolkit that keeps your pull requests honest about modern web platform usage. It scans your repo (or just the diff) for CSS selectors and Web APIs, compares them against the Baseline dataset, and produces actionable reports. Baseline tracks which web features are widely supported across major browsers, helping you make informed decisions about browser compatibility. Use it locally, wire it into CI, or drop the GitHub Action into any workflow. Uses Baseline data ( web-features ).

  Talanoa▲346

  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…

  Strange Attractors▲804

  I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  Autism Simulator▲779

  Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
