Setting Multiple Heroku Config Using Terminal

the command to set heroku config is heroku config:set. to setup multiple config, separate with whitespace, eg. heroku config:set KEY_ONE=VALUE_ONE KEY_TWO=VALUE_TWO. however, this format is hard to read & change when the there are many config vars. to separate thus config vars into lines, we use \.

the \ (backslash) tells terminal to break the line. notice that there's a whitespace before \. last entry for config var has no trailing \

heroku config:set \
KEY_ONE=VALUE_ONE \
KEY_TWO=VALUE_TWO \
KEY_THREE=VALUE_THREE \
LAST_KEY=LAST_VALUE

try copy and paste above code in your terminal. remember that you can only execute heroku command heroku config:set inside directory of heroku app.

to check available heroku apps in your machine, use heroku apps.

another example is when you want to set config for laravel app:

heroku config:set \
APP_ENV=local \
APP_DEBUG=true \
APP_KEY=DmRe0WkSOdiHpaNaUMD1jv4Wynpi1yPL \
