How to create a user model with node.js?

I'd like to create a model to handle everything related to users, starting with a findOne() function.

app.js:

var u = new User(client);
u.findOne(function(error, user) {
  console.log(error, user);
});

models/User.js:

var User = function (client) {
  this.client = client
};
User.prototype.findOne = function (id, callback) {
  client.connect();
  client.get('testkey', function(error, result) {
    var test = "hello@world.com";
    callback(null, test);
    client.close();
  });
};
module.exports = User;

node.js complains findOne() would be undefined.

What's the correct way of creating such models and providing them with objects, like database pools etc.?

Your code contains various errors:

  • You do not use new when creating the instance

  • You mixed a function with the object literal syntax:

    var User = function (client) {
  client: client
};

    You want this.client = client; instead. Right now the function body does nothing as it just defines a label called client does nothing with the variable client.

I would suggest you to search for an existing ORM for node.js instead of trying to write one on your own.
