Have you started the MongoD Service before connecting? - Oscar
nope I write the following code mongose.connect('mongodb://localhost/meanapp'); mongose.connection.once('open',function() { //Load the models console.log('Listening on port 3000...'); app.listen(3000); }); - Joan
nope I just write the code as //Connect to MongoDB mongose.connect('mongodb://localhost/meanapp'); mongose.connection.once('open',function() { //Load the models console.log('Listening on port 3000...'); app.listen(3000); }); - Joan

The error is saying that the connection have been refused (ECONNREFUSED). There is no endpoint listening on 127.0.0.1:27017

Mongo have a client-server architecture. Before connecting to the database, you need to start the database server. First, create a folder to store the data files. Then, from command prompt, go to where your mongo installations resides and write:

mongod --port 27017 --dbpath C:\path_to_data_folder
