Some simple oneliners that make working with Heroku easier

heroku_env.sh

# A collection of snippets for managing Heroku env vars
# It ain't pretty but it works

# Copy Heroku config to a local .env file
heroku config --app $HEROKU_APP | sed 's/: */=/' | tail -n +2 | tee $ENV_FILE

# Set a Heroku app's config from a local env file
# I got this oneliner from a blog somewhere, can't find it again
heroku config:set --app $HEROKU_APP $(cat .env | sed '/^$/d; /#[[:print:]]*$/d')
# Set a Heroku app's config from another Heroku app's config
heroku --app $HEROKU_APP config:set $(heroku config --app $HEROKU_APP_ORIGIN | sed 's/: */=/' | tail -n +2)

# Take a diff between two heroku configs (without messing around with temp files)
# Vimdiff is just what I prefer, any diff program which two files as input parameters will work
vimdiff <(heroku config --app $HEROKU_APP_ORIGIN) <(heroku config --app $HEROKU_APP)

# Locally run a process using a Heroku app's config (without copying to a temp file)
# If you wish to modify any of the config vars put them at the location of EXAMPLE_OVERRIDE=true
env $(heroku config --app $HEROKU_APP | sed 's/: */=/' | tail -n +2 | xargs) EXAMPLE_OVERRIDE=true node index.js
