ember install:addon ember-cli-coffeescript
NB: This addon requires ember-cli version
0.2.0 and up. It might work on
earlier versions, but I wouldn't know.
// app/components/my-component.jsimport Ember from 'ember';export default EmberComponentextendtagName: 'div';
export in a CoffeeScript-file causes an error, so we'll need
We also need to store the export in a variable to export at the end, we can't export directly as done above. Please note that the name of this variable does not affect the name of the component itself - that is based entirely on the file name and placement.
Here's the above file in CoffeeScript:
# app/components/my-component.coffee`import Ember from 'ember'`MyComponent = EmberComponentextendtagName: 'div'`export default MyComponent`
Luckily, all the blueprints included with ember-cli-coffeescript do this for you! Which leads to…
ember help generate to get a list of available blueprints. Use them by running
ember g <blueprint> <args>. For instance, to generate the above component:
ember g component my-component`
ember-cli-coffeescript comes with pod-support for the same blueprints as ember-cli does. Check out the ember-cli docs for pods for instructions on how to use it.
If you'd like to use ember-cli-coffeescript without the blueprints, you can add
the following to your
ENVcoffeeOptions =blueprints: false
This will make it fall back to the next blueprints in line (probably the ones from ember-cli).
This will happen automatically - no work necessary.
If you have a
coffeelint.json file in the root of you project we will automatically pick up on it and start running linting on files when using the
ember build and
ember serve commands.
If you do not want linting to run despite having a
coffeelint.json file, use the following configuration
ENVcoffeeOptions =lint: false
You can set
true to enable linting with the default configurations, but you will probably
want to add a
coffeelint.json file to the root of your project either way, for instance to turn
off the error for backticks.
You can find all the available options on the website for
If you want to specify a different path for your
coffeelint.json file you can specify the path
(relative to the project directory or absolute)
ENVcoffeeOptions =lint:configPath: "configurations/coffeelint.json"
If you want to change the way we format the output you can specify a custom error output and stats output
ENVcoffeeOptions =lint:console.log'Files: ' statsfileCount "Errors: " statserrorCount
NOTE: The lint results will show up twice when you build and run your app; once for the app files, and then once for the test files. On rebuild, only the changed files are linted.
To avoid linting specific files or folders, you can put a file named
in the root of your project containing ignore-rules, one per line. This is just like a
.gitignore-file, and it will follow the same rules.
