Environment Variables

There are a number of environment variables we use at build time to influence the output application's behavior.

# Application
NODE_ENV=< production | development >
DEBUG=< true | false >
APP_CONFIG=< relative path to application configuration file >
PUBLIC_URL=< relative path to application root - default / >
VERSION_NUMBER=<Set by CircleCI>
BUILD_NUM=<Set by CircleCI>
# i18n
USE_LOCIZE=<false>
LOCIZE_PROJECTID=<ProjectID to pull translations for>
LOCIZE_API_KEY=<To enable Locize live editing of translations>
