How to run

Let's say we have a node module script.js that exports a function main that computes some value and print it:

var fib = function(n) {
  if (n === 0) { return 0; }
  if (n < 2) { return 1; }
  return fib(n - 1) + fib(n - 2);
};

exports.main = function() {
  console.log(fib(10));
};

To run the script, we will have to add a new line into the file

exports.main();

Instead, we can use run-exported to run the exported main function like this:

run-exported script.js main
55

How to run with arguments

Let's say the main function now takes the number from arguments

var fib = function(n) {
  if (n === 0) { return 0; }
  if (n < 2) { return 1; }
  return fib(n - 1) + fib(n - 2);
};

exports.main = function() {
  console.log(fib(parseInt(process.argv[2], 10)));
};

To pass the arguments to the script, simply appending the arguments like this

$ run-exported script.js main 10
55
