In this new blog post, Jared White spotlights a feature of the Willowgarden application platform - the template modes.
Unlike many Web frameworks, Willowgarden doesn't provide a different template for every action. All actions are provided via a single template file for the entire page. This works because of the concept of template modes.
He includes a quick example of these templates, creating two files to show the difference - one with the normal templating methodology and the other showing the difference Willowgarden's templates make (more concise and more flexible).
