fancy-connfu-application.js

Don't be mistaken by the name, this is a very stupid example of how should a connFu application look like. This application only listens to voice and twitter events and prints them on the terminal.

Running this example

  • First of all, you have to register into connFu.com an application. You will receive an application token which will be very useful ;)

  • Then, install the connFu npm package:

     $ npm install connfu

  • Then get the source of this example from here and run it!

     $ node fancy-connfu-application.js <application_token>

             		           
                               
                            
                                
               
Application code explanation
             		                            
             		           
                               
                            
                                
               
As we plan to launch this application via the command line,
we should receive the application token as an argument, so we need 
to check that the application token is passed as a parameter
             		                            
if (process.argv.length < 3) {
  console.log("Usage: node fancy-connfu-application.js <application_token>");
  process.exit(1);
}
             		           
                               
                            
                                
               
Initializing the connFu application
             		                            
             		           
                               
                            
                                
               
First of all, we have to require the connFu package...



...and then initialize the connFu application using the application
token received from the command line
             		                            
var connFu = require('connfu');

var app = connFu.createApp(process.argv[2]);
             		           
                               
                            
                                
               
Adding a voice channel listener



Voice channels have three different events: join, leave and change_topic.
Inside the event listener we can add different handlers for each of those events



The params received in the event handler is an array with all the information about the event.
Check the docs for more detailed info about this object
             		                            
             		           
                               
                            
                                
               
Add the voice channel listener
             		                            
app.on('voice', {
             		           
                               
                            
                                
               
Add join event handler
             		                            
  join: function(params) {
    console.log('The number ' + params.from + ' joined to the conference with number ' + params.to);
  },
             		           
                               
                            
                                
               
And then a leave event handler
             		                            
  leave: function(params) {
    console.log('The number ' + params.from + ' left the conference with number ' + params.to);
  }
});
             		           
                               
                            
                                
               
Adding a Twitter channel listener
             		                            
             		           
                               
                            
                                
               
We can add a Twitter event listener very easily too:
             		                            
app.on('twitter', {
  
             		           
                               
                            
                                
               
Twitter channels only have the new event, which is received when a tweet is received
             		                            
  new: function(data) {
    console.log(data);
  }
});
             		           
                               
                            
                                
               
Start listening to the channels
             		                            
             		           
                               
                            
                                
               
This is how we start listening! Pretty easy, huh?
             		                            
app.listen();
