Creating a wrapper for promise based co-routine functions

db.js

//This is the DB file im writing the fucntions in
const redis = Promise.promisifyAll(require('redis'));
const client = redis.createClient();
const Promise = require('bluebird');
const {coroutine: co} = require('bluebird'); //Alias coroutine
const wrapper = require('./lib.js');

module.exports.SomeFunction(key, value) {
  return wrapper(function(){
    let set = yield client.set(key, value);
    return Promise.resolve(set);
  })
} 

lib.js

//Lib
'use strict';
const Promise = require('bluebird');
const {coroutine: co} = require('bluebird'); //Alias coroutine

module.exports = function(func) {
	return new Promise((resolve, reject)=>{
	 co(function* () {
            try {
            	//Want to execute the function here
                func().then(result => {
                	resolve(result);
                }).catch(e => {
                	reject(e)
                })
            } catch(e) {
            	reject(e);
            }
        })()
	});
}
