Create own response

If you want to add you own responses you should pass absolute path to module constructor

require('express-custom-response')(__dirname+ '/api/responses');

Then each script in this directory will be available as response method by filename. Example:

/** 
 * api/responses/accepted.js
 *
 * This will be available in controllers as res.accepted(message);
 */

module.exports = function(redirectTo, extra){
    //this is points to express.response
	this.status(202);
	this.send(message);
}

If you want to override exists pre-defined response simple add new script to your directory with name of response which you want to override
