Procfile

# Free deployment to Heroku.
#
#   !! Warning: You must use a 64 bit machine to compile !!
#
#   This could mean using a virtual machine. Give your VM as much memory as you can to speed up linking.
#
# Basic Yesod setup:
#
# * Move this file out of the deploy directory and into your root directory
#
#     mv deploy/Procfile ./
#
# * Create an empty package.json
#     echo '{ "name": "cruzo", "version": "0.0.1", "dependencies": {} }' >> package.json
#
# Postgresql Yesod setup:
#
# * add dependencies on the "heroku", "aeson" and "unordered-containers" packages in your cabal file
#
# * add code in Application.hs to use the heroku package and load the connection parameters.
#   The below works for Postgresql.

# Heroku setup:
# Find the Heroku guide. Roughly:
#
# * sign up for a heroku account and register your ssh key
# * create a new application on the *cedar* stack
#
# * make your Yesod project the git repository for that application
# * create a deploy branch
#
#     git checkout -b deploy
#
# Repeat these steps to deploy:
# * add your web executable binary (referenced below) to the git repository
#
#     git checkout deploy
#     git add ./dist/build/cruzo/cruzo
#     git commit -m deploy
#
# * push to Heroku
#
#     git push heroku deploy:master


# Heroku configuration that runs your app
web: ./dist/build/cruzo/cruzo production -p $PORT
