Push Variables to Heroku
If you use Heroku to deploy your apps, I have a great command to try.
Included in the Heroku toolbelt command-line interface is heroku config:push.
This command pushes your local environmental variables, defaulting to a file called .env in your root directory, to any Heroku remote. It favors existing remote configs in the event of a collision.
No more copying and pasting to the command line, or pointless typos while setting remote configs.
Bonus: also check out heroku config:pull— equally useful.
