What SendHub Learned Building a Single-Page Backbone.js App

SendHub has put up a post on things its developers learned in rebuilding the front-end of its Web site as a single-page application with Backbone.js. This includes everything from template rendering to "avoiding a zombie apocalypse."

The company decided to give SendHub.com a facelift because "the site looked a bit dated, and it just didn't feel as snappy as we wanted it to. All pages were rendered almost entirely on the server, and only a couple of places used Ajax to pull in data asynchronously." The company also wanted to test out its developer API>.

Because Backbone.js has a dependency on Underscore.js, they decided to use it over Mustache, Handlebars and other rendering libraries. This turned out to be a good choice because it not only saved them from having to load an additional library, they also didn't need the extra features provided by the other libraries.

Killing Zombies

Another "big learning opportunity" in building the new front-end, was "in understanding the importance of killing zombies." In this case, we're talking about objects that "you can't access directly, but live inside the application and take up memory resources." Basically, SendHub says these crop up "when you forget to clean up event listeners after objects are removed from the page (usually they are view objects)."

The best zombie-killing resource, according to SendHub, is Derick Bailey's "Zombies! Run! (Managing Page Transitions In Backbone Apps)", which explains how to use a close method to avoid zombies.

SendHub also talks about how to use a global dispatch object to get Backbone.js views talking to one another, "without tightly coupling them to each other."

If you're new to Backbone.js, SendHub's post is worth reading.

Death By Wikipedia: Encyclopedia Britannica Stops Printing

So many things about printed encyclopedias seem insane now. The space that dozens of volumes takes up. How much an entire set weighs (well over 100 pounds). The fact that many middle class families used to have to pay for them in regular installments. How slowly they are updated with new information.

Today, we have a reservoir of infinite knowledge, most of which is virtually free to access. It takes up no more physical space than the tiny devices we use to view it.

Sponsor

In a move that will surprise very few, Encyclopedia Britannica is expected to announce that it will no longer print its 32-volume set of printed encyclopedias, the New York Times reports. This comes 244 years after the iconic reference books first went to press.

The usefulness of such reference materials has been on the decline for years, especially since the advent of Wikipedia. Whatever flaws its open, crowd-sourced editorial model may invite, Wikipedia is generally regarded as a comprehensive and mostly-accurate source of information, which can be accessed for free.

It is also instinctively turned to by a new generation of students, as well as casual researchers around the globe. It now ranks as the sixth most-visited website in the world, according to Alexa.

Just because Britannica is shutting down its print operations doesn't mean its encyclopedia and other educational products will cease to exist. In fact, the print edition makes up a tiny percentage of the company's revenue at this point. It brings in more money from selling other educational materials and offering paid access to its website, which remains a more up-to-date and multimedia rich resource than print ever could be. It also has advertisements.
