in plain english

MicroJS.com is a curated directory of tiny, focused JavaScript libraries, tools that do one specific job extremely well, without bloat. Think of it as a shopping guide for developers who need a small, powerful solution rather than a massive framework. Instead of loading a 100K library when you only need 5K of functionality, you can browse here to find exactly what you need. The site works like a community-driven catalog. Someone creates a small library (say, a date formatter, animation helper, or data validator), and developers can submit it to the directory by adding an entry to a shared list. The site then displays each library with its size, purpose, and a link to download it. The catch is that libraries have to meet strict rules: they must be under 5K when compressed, have no dependencies, work without external code, and be released under a permissive open-source license. This keeps the quality high and ensures you're getting genuinely lean code, not just marketing fluff. Who would use this? Web developers building lightweight projects, mobile-first web apps, or situations where every kilobyte matters. A startup building a time-tracking widget doesn't need React or Vue, they might find a 2K date library here instead. Frontend engineers optimizing for slow networks or embedded web contexts. Or anyone who's frustrated with the complexity of modern JavaScript ecosystems and wants to understand exactly what code they're pulling in. The README doesn't detail how the site itself is built, but it emphasizes that all submissions go through a build process that verifies size claims and checks for errors. Contributions come from the community via pull requests, with libraries scattered randomly through the list to make merging easier when many people submit at once. It's a deliberately minimal, hand-curated approach, no auto-generated content, just real libraries that solve real problems in the smallest way possible.
