Answer 1

1. Create a .env File to store your environment variables. Example: .env.development or .env.test or .env.production files that you can put into a config folder.

2. Download the node module "node-foreman" https://github.com/strongloop/node-foreman

3. Now run your web server using foreman and specify which environment you want with the following command line command.

./node_modules/foreman/nf.js --env ./config/.env.development start web=1

That will load the correct environment that you want.

Then to access your environment variables in the actual code, you use "process.env".

For example if you have a key-value pair in your .env file like version=5.5 then to access it in the code you do process.env.version.
