param

param

A tiny module to read config parameters for your node application.
It's avaiable through npm:

npm install param

what?

Param exposes a single function that finds a config parameter

// example.js
var param = require('param');
var port = param('app.port');

console.log(port);

The above example tells param to find the parameter app.port. It does so by first looking at the command line arguments

node example.js --app.port 8080 # prints 8080

If present param will simply return that value.
Otherwise param will look for a configuration file called config.json or specified by --config [filename] or your NODE_ENV env var.

If NODE_ENV=development it will look for a config file called development.json and similar.

It will start looking for the config file in . and ./config. If it doesn't exist it will try in .. and ../config until it reaches /.

// config.json
{
	"app": {
		"port": 8888
	}
} 

Running the example again with the above file saved as ./config.json

node example.js # prints 8888

Happy configuring!
