Confilter

Load and transform configuration files using chains of recycleable filters:

var confilter = require('confilter');

var config = confilter([
  confilter.loadJSON([
    './config.' + process.env.NODE_ENV + '.json',
    './config.json'
  ]),

  confilter.defaults({
    role: 'api',
    port: 3200
  }),
]);

Custom Filters

Custom filters are functions that accept and return the config object. A silly example from the test suite will multiply any numeric config values by two:

function timesTwoFilter (config) {
  Object.keys(config).forEach(function (k) {
    if (typeof config[k] === 'number') config[k] *= 2;
  });
  return config;
}

This filter can then be used like any other:

var config = confilter([

  confilter.loadJSON([
    './config.json'
  ]),

  timesTwoFilter
]);
