liveconf

liveconf

A very simple and barebones configuration module. Just allows runtime configuration objects to be synced with JSON configuration files.

**For a much more solid module on cofiguration, check out node-config. **

Install

npm install liveconf

Use

Have a configuration file with some configuration. e.g. config.json

{
   "a":8,
   "b":"foo"
}

var liveconf = require('liveconf');
 
// get the configuration from a file
var config = liveconf('config.json');
 
console.log(config.b); // foo 

The configuration object will be cached and will always be the same for the same configuration file. The configuration file is watched so any changes are reflected on the object.

While the code is running you can change the configuration.

{
   "b":"bar",
   "c":42
}

console.log(config.b); // bar

Events

Each configuration object exposes an EventEmitter through a non-enumerable readonly property ee. There is only one event changed, fired when the configuration object is changed.

var liveconf = require('liveconf');
var config = liveconf('config.json');
 
config.ee.on('changed', function() {
    // config file has changed
});
