Microjs, a directory of Micro-Frameworks and Micro-Libraries

May 5th, 2011

I’m thrilled to announce the launch of microjs, a directory of JavaScript Micro-Frameworks and Micro-Libraries, something that grew out of some reactions to my post on micro-frameworks in early April.

How much library code do you really need — 50K? 100K? 150K? More? How much of that do you really use?

Sure, we all love our favorite monolithic frameworks, and sometimes we even use them fully. But how often do we reach for the ride-on John Deere tractor with air conditioning and six-speaker sound system, when a judiciously applied pocketknife would do the trick better, faster, slicker?

Micro-frameworks are definitely the pocketknives of the JavaScript library world: short, sweet, to the point. And at 5k and under, micro-frameworks are very very portable. A micro-framework does one thing and one thing only — and does it well. No cruft, no featuritis, no feature creep, no excess anywhere. helps you discover the most compact-but-powerful microframeworks, and makes it easy for you to pick one that’ll work for you.

Want to add your own? Fork it on GitHub, add your framework to data.js and submit a pull request.

Microjs was released as part of JSConf 2011 in Portland, Oregon, and I will release my talk slides and comments in an additional blog post later this week.

A big thank-you goes out to Dustin Diaz of Twitter who helped me sanity-check everything and is busy improving Microjs; and my awesome wife Amy Hoy for providing great copy and moral support!

Last but no least, thanks to all the contributors who already added their favorite libraries—keep it coming!
