3.1.0

And another patch down. This time around it's mostly maintenance and a bit of perf:

  • The addition of the nanoraf dependency prevents bursts of DOM updates thrashing application performance, quite possibly making choo amongst the fastest frameworks out there.
  • We now ship standalone UMD bundles on each release, available through https://npmcdn.com/choo. The goal of this is to support sites like codepen and the like; this should not be used for production.

3.0.0

Woooh, happy third birthday choo - thanks dad. You're all grown up now; look at how far you've come in the last month. You've grown... tinier? But yet you do more? I love you choo - shut up dad.

Notable changes

Who's the tiniest of them all?

choo is now 5kb optimized! That's 2kb less compared to v2. Woah, how? We now support yo-yoify which optimizes those lil template tags to document.createElement() calls. So not only is it smaller, creating elements now has no overhead. Pretty nifty eh? Mad shoutout to Shama for building this!

Captain Hook(s)

V3 introduces hooks - powerful functions that are called at certain points in the refresh cycle. Unlike functions in models these functions have unfiltered access to all properties, call stacks and more. They're super useful when building error handling, logging or persisting for stuff like hot reloading. I quite like them, and I'm def keen to see what uses people will come up with!

Effect Composition 🚋🚋🚋🚋

effects are now composable by calling a done(err, res) callback when they're done executing. This means that multiple namespaced effects can be chained together to form some higher level behavior.

Think of cases like "logout" - multiple models must be cleared, perhaps tokens invalidated on the server, all in a certain order. This requires multiple models to work in tandem. - And now that's possible! ✨

Pathfinders guide

We've started work on the choo handbook - a lil manual to help you get started, not only with choo, but with web development in general. It's super modest still, only containing a single choo tutorial, but we'll be expanding this over the coming months. If you want to contribute some docs, there's a whole section of ideas on stuff that might be neat to write. Any lil bits are welcome! Shout out to Tim for making this happen 🎉

The Cycle of Life

views have gone through a bit of a change - they're now required using require('choo/html') so they can be factored out of a project into standalone bel components at any time. But additionally these components have gained super powers through the adition of onload and onunload hooks. Components can now react to being mounted or not, which makes them ideal to implement standalone widgets. This behavior uses html5 MutationObserver under the hood, so it will work anywhere with a DOM! Again, this was all Shama's hard work.

Test coverage

choo has gained a beaut blanket of tests, courtesy of Todd and Ben. We've got server, browser and pretty-much-all-browsers-known-to-mankind style testing which should give us a pretty good idea if stuff breaks. Neat!

Core dump

Internally we've moved the core of choo into a separate package - barracks. choo is now mere glue code around barracks, yo-yo and sheet-router. This is good news for folks who like choo, but don't agree with all decisions. Go forth and build your own lil framework!
