Heroku buildpack to make environment variables available in build time.
.env-export file at the repository root and list the
variables you want to export (one per line):
$ cat .env-export MY_FIRST_VAR ANOTHER_RANDOM_VAR
Add this buildpack to your app. Make sure this is the first buildpack in the buildpack list.
$ heroku buildpacks:add --index 1 --app my-app https://github.com/loadsmart/env-buildpack
Done! Next time you deploy your code, the variables you specified in
.env-export file will be available in the compile phase.
Note: Although you can export (almost) any variable, avoid exporting any variable that could result in a side-effect during build phase.
We use heroku-buildpack-testrunner to test the project. The test command will clone the repository automatically and will run the tests:
# This will clone the heroku-buildpack-testrunner $ make test
If you make changes to the buildpack that you think will benefit others, please send a Pull Request. Just make sure that the tests passed before opening it.
