title: Real time notifications node.js
body: <p>I'm developing a calendar application with Node.js, express.js and Sequelize.</p>
  <p>The application is simple, you can create tasks in your calendar, but you can also assign some tasks to others users of the system</p>
  <p>I need to create a notification system with socket.io, but I don't have experience with websockets. My big doubt is how can I make my server send a notification to the user that you assign the task?</p>
  <p>My ports configurations is on a folder called bin/www, my express routes are defined on a file called server.js</p>
  <p>Any Idea?</p>
