Paying For JavaScripts? Just View Source is an online marketplace for developers to sell themes, templates, and other web development related goodies. A lot of the files are for the backend making it next to impossible for someone to copy them without breaking into your server. But ThemeForest offers JavaScripts for sale and even offers a live preview.

By the very nature of the web, a front end technology like JavaScript requires the source code to be downloaded to your computer before it can run. This means anyone with a little know-how can easily bypass the need to buy the script and piece it together themselves.

For example, take this JavaScript calendar widget which has 0 sales as of this writing. All you have to do is go to the live preview and remove the frame by clicking the link in the top left corner. From there it’s just a matter of viewing the source (Choose View->Source in Internet Explorer, View->Page Source in Firefox) and copying the necessary JavaScript and CSS files. Here’s everything you need for this calendar widget:

Now before you get all upitty about the ethics behind this, you should know that this script is freely available from the author’s own site, which was based on an open source project from around 2006 according to comments in the CSS files.

Granted ThemeForest isn’t targeted at professional developers like me so someone might be more than happy to plunk down $8 to download everything in one nice, neat package. But if I were selling scripts on ThemeForest, with the expectation of a profit, I would be pissed that ThemeForest didn’t take more precaution to protect my source code. At the least they could obfuscate the live preview code using a tool like /packer/.

At any rate this demonstrates why it’s so hard to sell JavaScripts by themselves due to the very nature of how they work in an open web.
