env2js is a straight forward way to add config settings to your frontend application using environment variables. This comes in especially handy when you are setting up your services for docker using environment variables and want to use the same variables for your app config.

Installing

npm install env2js

Running

node env2js --in infile.js --out outfile.js

Demo

export ENV=DEBUG
export DEBUG=1

create config.js

var config = {
	debug: '{DEBUG}',
	env: '{ENV}'
};

run

node env2js.js --in config.js --out config.out.js

result

var config = {
	debug: '1',
	env: 'DEBUG'
};
