One solution might be to include a javascript runtime in your app such as monkey (https://github.com/idada/monkey) , load a javascript template framework like underscore.js(http://underscorejs.org/) into the runtime context and create a render function that takes a JSON string and template string as parameters. You can then write the return value back into your "http response".

It's a bit of a hack/convoluted solution but it allows you to make use of a few javascript template libraries which are IMHO more pleasant to work with.
