Discussing Server-side and Other Essential Components for Your Playground

The aim of this entire series was to teach you how easy it is to create a playground like CSSDeck, in reality. We covered everything from building the environment to making it secured. Then we integrated an amazing piece of code editor and finally discussed how to build a nice, performant and secured gallery to show the “real” interactive but scaled down previews of your creations. Although, you might need some extra bells and whistles.

Using HTML5 postMessage For a Secured Cross Domain Communication and Rendering

In the previous post, we covered how easy it is to build an environment where anyone can write in HTML, CSS, JS code that gets rendered and displayed in a sandbox (iframe) in realtime. It’s all good as long as the platform is restricted to yourself, but when it becomes open, i.e., when others can create testcases or use it for some other purpose as on CSSDeck, you need to start thinking about security.
