This buildpack will work out-of-the-box with Ember CLI generated applications. It installs node, nginx and generates a production build with the Ember CLI.
Creating a new Heroku instance from an Ember CLI application's parent directory:
$ heroku create --buildpack https://github.com/tonycoco/heroku-buildpack-ember-cli.git
$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack
...
You can set a few different environment variables to turn on features in this buildpack.
Set the number of workers for Nginx (Default: 4):
heroku config:set NGINX_WORKERS=4
Set an API proxy URL:
heroku config:set API_URL=http://api.example.com/
Set your API's prefix path (Default: /api/):
heroku config:set API_PREFIX_PATH=/api/
Note that the trailing slashes are important. For more information about API proxies and avoiding CORS, read this.
Have a staging server? Want to protect it with authentication? When BASIC_AUTH_USER and BASIC_AUTH_PASSWORD are set basic authentication will be activated:
heroku config:set BASIC_AUTH_USER=EXAMPLE_USER
heroku config:set BASIC_AUTH_PASSWORD=EXAMPLE_PASSWORD
Be sure to use https when you set this up for added security.
For most Ember applications that make any kind of authenticated requests (sending an auth token with a request for example), HTTPS should be used. Enable this feature in nginx by setting FORCE_HTTPS.
heroku config:set FORCE_HTTPS=true
Need to make a custom nginx configuration change? No problem. In your Ember CLI application, add a config/nginx.conf.erb file. You can copy the existing configuration file in this repo and make your changes to it.
The Ember CLI buildpack caches your npm and bower dependencies be default. This is similar to the Heroku Buildpack for Node.js. This makes typical deployments much faster. Note that dependencies like components/ember#canary will not be updated on each deploy.
To purge the cache and reinstall all dependencies, run:
heroku plugins:install https://github.com/heroku/heroku-repo.git
heroku repo:purge_cache -a APPNAME
