That boilerplate uses pre-commit hooks and run some scripts before making git commit. To see what is started before commit check package.json pre-commit block. Default - yarn lint:all and yarn test. To ignore the check, use -n e.g git commit -n -m 'Your amazing commit msg'.
cp .env.example .env - copy example dotenv file and specify your own values in .env
You can use different environment variables. Create .env.stage, .env.prod and .env.dev and copy the file you need.
To access values inside application call console.log(process.env).
