Overview of this book

<p>Meteor is a brand new platform built entirely in JavaScript that allows you to build modern, dynamic web applications in the blink of an eye. With support for nearly every popular JavaScript framework (and more being added every day), Meteor provides you with the ability to quickly and easily develop sophisticated and stylish web applications.<br /><br />"Getting Started with Meteor" is an easy to follow, step-by-step approach to learning how to build modern web applications with Meteor. Through the development of a complete and ready-to-use application, you will experience exactly how easy and fast it can be to develop robust, flexible web applications, so you can build your own “killer” app in no time.<br /><br />"Getting Started with Meteor" will walk you step-by-step through all the major advantages that Meteor has to offer. You’ll be up and running in less than two minutes, and will develop an actual application you can use. As you move quickly through the exercises, you’ll be able to experience first-hand how easy it is to develop in Meteor, and will gain invaluable best practices you can apply immediately to your coding projects.<br /><br />You will learn about reactive programming and how Meteor takes advantage of the latest web technologies. You will gain a solid understanding of what&nbsp; the best design patterns are for developing web apps, and when to use them. You will learn how Meteor uses HTML templates and NoSQL (document-based) databases together to make coding applications simple and fun. Finally, you’ll gain best practices for security and performance, making your web applications fast, secure, and easy to use.

Multiple clients


Good things should be shared. Meteor gets this, and as we're about to see for ourselves, the reactive programming model allows us to share updates in real time, across multiple clients.

With your Chrome web page still open to http://localhost:3000/ open a new browser tab and navigate to the same page.

Tip

If you really want to get fancy, you can conduct this same experiment with multiple browsers (Firefox, Opera, or Safari) – each session is live and reactive!

You now have two clients open, which are simulating the application being opened by different people, at different locations, with different computers. Meteor's reactive model allows you to treat all clients the same, and a change made by one will be propagated to all the others.

With your eyes on the new second browser, type the following command into the console on browser #1:

> lists.insert({Category:"Vinyl Records"})

You will notice that the change propagates to both browsers, and again without the page refreshing...
