This blog post builds off the ideas started by Preston Sego, Dan Gebhardt, and many others.

Moving Past Controllers

It's been really exciting to see Ember turn a new page with its move towards modern JavaScript and slimming of its API surface. Routes rendering a template that is backed by a controller remains the most obviously clunky part of the Ember API. Getting consensus on moving query parameters and having routes load components will give us an API that we don't have to make excuses for (especially in conjunction with Component Templates Co-location).

This might go without saying, but as part of this change, the loading and error substates should render components, rather than templates.

Address the Hierarchy of Skepticism

Like most Ember developers, I want to see Ember's marketshare and mindshare grow in 2018. At EmberConf 2017, Tom presented the Ember Hierarchy of Skepticism:

1. Metamorph Tags/ {{bindAttr}} (addressed!)
2. No Documentation (addressed!)
3. Custom Object Model
4. Big File Size
5. Monolothic

// VARIABLES

// assign a variable to something - use the `var` keyword
var myVariable = "i love variables";

// change the value of an existing variable - don't use `var`
myVariable = "i REALLY love variables";

// change the value of a variable in place
myVariable = myVariable + " - don't you?";
