In the root of your ember-cli project directory, run:
ember install ember-cli-spinjs
Now you in your templates you can use {{ember-spinner}}
to add a spinner to your page.
Default
Add two folders to your app the first called config
and in that folder
another called ember-spinner
with a file called standard.js
export default {
color: 'blue',
lines: 10,
length: 30,
zIndex: 200000
}
Spinning Lines
Fast spinning blue dots.
The Spin.js docs
