HTMLBars, how do I even?

Godfrey Chan is a stand-up Canadian. You might know him as a Ruby on Rails core team member or from his recent contributions to Ember.js. He currently work for Tilde Inc in Portland, Oregon, splitting his time between building Skylight and open-source consulting. In his previous life, he was also an award-winning WordPress™ plugin author.

Three Handlebars templates walk into one of the newly-opened HTMLBars on the block. After having a few drinks, they each put down a $100 bill. The renderer said to them, “sorry, no change” and left the DOM untouched.

In this talk, we will take a close look at this library that powers Ember's “Glimmer" rendering engine under-the-hood. What is HTMLBars? What does it actually do? How does it work? How does it compares to React’s Virtual DOM or Google’s Incremental DOM? Is it even fast? Can I use it without Ember? Come on over and see for yourself!

Broccoli & Build Performance

Stefan Penner is an Ember.js core team member, attends TC39 for Yahoo, a Principal Software Engineer at Yahoo, and a prolific open source contributor to many projects including ember.js, ember-cli, ember-data and Babel.js

As we start relying on precursors to browser-ready assets for development (ES6, SASS, JSX, Handlebars), build tool performance becomes an important issue for maximizing developer productivity. Stefan will discuss the finer points of build tool performance from his experience as a core contributor to Broccoli and Ember-CLI.
