Cross-Pollinating Communities

• esnext tables

select-ing good ember patterns (Brenna O'Brien)

http://talks.brennaobrien.com/ember-select/selecting-good-ember-patterns.pdf

• get helper

  disabled={{get fruit disabledKey}}

useful in cases where we would typically produce a sub-component or a CP in the component

• cool trick I've seen in a few demos

  let selection = this.get('fruits').findBy('id', +value);

the +value part converts the string over to an int without parseInt

Ember + Electron (Felix Rieseberg)

Living Style Guide Driven Development (Chris LoPresto)

• "thoughtful composition using components yields an app that is coherent, flexible and maintainable"
• decompose a design into the components that it's made of
• allow passing through edge case data
  • empty
  • "expected"
  • "wow" - outliers and edge cases https://github.com/chrislopresto/ember-freestyle
