Sheer Cliff CMS is a simple and powerful content management system (CMS) for Node JS.

var mongoose = require( 'mongoose' );
var logger = require('./logger');
var config = require('./config');

module.exports.mongoose = mongoose;

/*
done: (err)
 */
module.exports.connect = function(done) {

    var uri = config.settings.database_connection;

    // If the connection throws an error
    mongoose.connection.on('error',function (err) {
        logger.error('Mongoose default connection error: ' + err);
        done(err);
    });

    // When the connection is disconnected
    mongoose.connection.on('disconnected', function () {
        logger.warn('Mongoose default connection disconnected');
    });

    // If the Node process ends, close the Mongoose connection
    process.on('SIGINT', function() {
        mongoose.connection.close(function () {
            logger.warn('Mongoose default connection disconnected through app termination');
            process.exit(0);
        });
    });

    mongoose.connection.on('connected', function () {
        logger.info('Mongoose default connection open to ' + uri);
        done();
    });

    mongoose.connect(uri);
