I'm researching a means of using Mustache templating for the view engine in CQ5, which uses Sling. I'm looking for some advise if anyone has already had experience going into this.

I need to use a template format that can be shared between front and back end when required. So mustache is ideal, however, other options may be applicable, such as handlebars.

I have found a git repo for "sling-scripting-mustache" which I am looking into but it lacks any kind of documentation. I will be giving it a try nonetheless.

Would appreciate any thoughts and guidance :)

  • offtopic, but make sure mustache is your best bet, people often realize they need something that allows for a little more logic, in this case handlebars is a great option. – j_mcnally Apr 18 '13 at 20:03
  • Agreed, I would love to start down that path with handlebars. My problem might come later tho as I will have to find similar solutions for .Net, php, and other environments. Mustache seems to have solutions for those, but I haven't found the same solutions for handlebars. – David Apr 18 '13 at 20:11
  • well handlebars should be languge agnostic as it is run on the client not the server. – j_mcnally Apr 18 '13 at 20:28

Handlebars has been in CQ since 5.6:

The handlebars javascript library was originally added to CQ in 5.6.0 for other purposes. The java version of handlebars is included in AEM 6.0, and in a featurepack for 5.6.1 that contains the Social Component Framework (SCF) (source)

You can write Mustache templates and render them with Handlebars:

Mustache templates are compatible with Handlebars, so you can take a Mustache template, import it into Handlebars, and start taking advantage of the extra Handlebars features (source)

There's some more info here.

my workflow is usually to compile handlebars or mustache outside of the language pipeline with something like grunt and then include it as a seperate js file.

Now if you are actually trying to do server side templating thats a different issue. Not sure how well handlebars works as a server side template but mustache does for sure.

The code in the repo (https://github.com/lykorian/sling-scripting-mustache) builds a OSGI bundle with the scripting engine information embedded in its metadata.

Based on what I can see in the pom file, you should install the dependencies:

mvn -Pinstall-dependencies install

And then build and install the actual bundle by installing it in the OSGI console or running maven (check the pom for the default values):

mvn -Plocal-author install

Once that is installed, the scripting engine should be installed and it should recognize *. mustache files.

Disclaimer: I haven't tested this, these are just my thoughts based on what is in the code and in the pom file. Hope it helps!
