Configuration

Ember CLI’s runtime is configurable via a file named .ember-cli. The JSON-formatted file is in project's root directory and can include any command-line options for ember generate, ember serve or ember test.

Command line options are passed in a dasherized form on the command line but they must be in camel cased in .ember-cli. For example

ember serve --live-reload false

would be liveReload in the configuration file.

{
  "liveReload": false
}

Every development environment will be different but a realistic example setting --port and --proxy is shown below:

{
  // disableAnalytics added by ember new
  "disableAnalytics": false, 
  "port" : 8080,
  "proxy": "http://localhost:3000"
}

For a complete list of command line options run ember help.
