I was trying to run my koa app.js file but I could not get it to work.
Here's my app.js
var koa = require('koa'),
monk = require('monk'),
wrap = require('co-monk');
var db = monk("mongodb url here"),
collection = db.get('mycollection'),
transactions = wrap(collection);
var app = koa();
app.use(function*(){
var res = yield transactions.find({});
console.log(res);
});
app.listen(3000);
and here's the error i got:
TypeError: Cannot read property 'name' of undefined

I'm still new to Koa,nodejs so I'm having a hard time figuring this out. Any help would be great!

I am facing a problem with moongoose js
This is my node js code:
var mongoose=require('moongoose');
var test=mongoose.Schema({test:String})
module.exports = mongoose.model('test',test);
When I run this code, node js throws:
var test=mongoose.Schema({test:String})
^

If I change this code to this format:
var mongoose=require('moongoose');
var Schema = mongoose.Schema;
var test=new Schema({test:String})
module.exports = mongoose.model('test',test);
That code throws:
TypeError: **Schema is not a constructor**
Please help me to resolve this code error.
Its require('mongoose'); you have written require('moongoose');
an o typo :))
My code is as shown below:
app.js
const app = express();
const itemsRouter = require('./routes/items.js');
app.use(bodyParser.urlencoded({
extended: true
}));
app.use('/items', itemsRouter);
items.js
const router = require('express').router;
router.get('/itemTest', (req, res) => {
res.json({
sucess: true
});
console.log(`the parametrs are ${req.body.item_name} ${req.body.item_post}`);
});
module.exports = router;
But here somehow, I am not able to get the router working and it says that can not read property 'get' of undefined.
the error stack is as shown below:

There are two problems here:
It's express.Router and not express.router.
You need to create a new instance of express.Router (e.g. var router = new express.Router()) instead of trying to using the constructor directly as an instance.
I config DATABASE_URL in my dashboard.
When I do in my prompt heroku config
I get:

but I get this fail:

My file where I get the fail models.js
var path = require('path');
// Postgres DATABASE_URL = postgres://user:passwd#host:port/database

console.dir(process.env.DATABASE_URL);
var url = process.env.DATABASE_URL.match(/(.*)\:\/\/(.*?)\:(.*)#(.*)\:(.*)\/(.*)/);
I have created my file .env with the following values in the root :

This is NodeJS 8.22 on Windows 7*
You have a typo in your code.
util.inherits( Website, events.EventEmiter );
Should be
util.inherits( Website, events.EventEmitter );
