Page Template vs. Component Site Architecture

In the last couple projects that I’ve worked on, I’ve been faced with a very common question.  How should we architect the solution, using Components or Page Templates?  Components meaning a piece of data that can be used in multiple places and can be rendered anywhere on the page.  Essentially a free way of designing a web page without needing a developer’s intervention.  Page Templates meaning a much more rigid design of the pages that will prevent possible design complications.  There are major pros and cons to both of these options, and most people will end up wanting a combination of the two.

Page Template Architecture

However, there are few downfalls to this architecture.  If you wanted to allow for any additional data to be added to the page, it would require some developer intervention to not only add the field in Sitecore, but to add the ability for the code to render that data.  This architecture also doesn’t make any repeated data easy to content manage.  Each time you created a page, you’d need to re-enter any repeated data.  Unless, of course, it is set in the Standard Values of that template.

Component Based Architecture

There are also some very noticeable disadvantages for this architecture.  One of the biggest ones is that the content you enter is separate from the page itself.  So, you’ll need to not only create the page, but you’ll need to create the datasource as well.  Another disadvantage is the default Sitecore Placeholders don’t take into account adding multiple of the same placeholder (eg. adding two 2 column renderings that have “leftcolumn” and “rightcolumn” placeholders).  This can be solved by the use of Dynamic Placeholders.  However, Dynamic Placeholders aren’t an out-of-the-box solution from Sitecore.  So, there will need to be some custom work added to enable that ability.
