About this project

This project is to be used as a buildpack in a heroku application to check whether or not all the environment variables that are set in the .env.development file are present or not.

1. Make sure that you have a .env.development file in the root of you project
2. If some of the varialbles in the .env.development are optional, you can create a file called .env.optional, variables listed in there will not make the script to fail
3. Just add this buildpack before any buildpack that might depend on the varialbles being checked

If you have a .env.development file like this:

SOME_API_KEY=the value of the key
OTHER_ENV_VAR:hello
#COMMENTED_VAR=I am not checked

The script will only pass if the SOME_API_KEY and OTHER_ENV_VAR are set for you heroku application

Now, if you have a .env.optional file with:

#SOME_API_KEY
OTHER_ENV_KEY

Then only the SOME_API_KEY is necessary to be present
