Creating our own package

To create our own package, we will use our ReactiveTimer object, which we built in Chapter 9, Advanced Reactivity:

1. We go to our terminal, in our app's folder and run the following command:

   $ meteor create --package reactive-timer
   

2. This will create a folder named packages with a reactive-timer folder inside it. Inside the reactive-timer folder, Meteor has already created a package.js file and some example package files.
3. Now we can delete all the files inside the reactive-timer folder, except the package.js file.
4. Then we move the my-meteor-blog/client/ReactiveTimer.js file, which we created in Chapter 9, Advanced Reactivity, to our newly created reactive-timer package folder.
5. Lastly, we open the copied ReactiveTimer.js file and remove the following lines:

   timer = new ReactiveTimer();
   timer.start(10);

   Later, we'll instantiate the timer object inside the app itself and not in the package file.

We should now have a simple folder with the default package.js file and...
