As I discussed in "Interactive Static Sites With Jekyll, Backbone.js, and Firebase", static sites built using powerful Ruby-based tools such as Jekyll and Middleman are surging in popularity based on their benefits: low hosting costs, speed, stability, and security. Jekyll has powered the Obama campaign's $250 million fundraising platform as well as a new version of healthcare.gov. Several months ago GitHub Co-Founder and CEO Tom Preston-Werner renewed his commitment to Jekyll, writing, "Sorry for not keeping this thing moving faster. 2013 is gonna kick ass. Wake up, go to war."
So, this certainly sounds like good news for rubyists. But is there a tool for creating static sites using Node.js and CoffeeScript?
Say hello to DocPad.
DocPad embraces CoffeeScript in a big way.
For starters, let's take a look at a typical DocPad configuration file. Whoa! Not only is it in CoffeeScript, it even contains functions! Used judiciously, the ability to include short, readable CoffeeScript functions in your configuration is quite handy. For an interesting example, check out the instructions for using DocPad, GitHub and Prose as a Wiki. (Aside: After publishing this post, I will use Prose and GitHub as described to add a link to my post to the official DocPad showcase.)
The DocPad core and almost all of its community plugins are written in CoffeeScript, but that's not all. Although DocPad supports a long list of renderers that includes Handlebars and Jade in addition to PHP and Ruby, the project's skeletons have a strong preference for Eco (Embedded CoffeeScript) templates. For an example of a typical Eco template, check out getting-started.html.eco.
If you enjoy CoffeeScript and Eco (it also uses Backbone.js), I encourage you to jump in and give DocPad a try. I have posted my notes about porting blog.scriptybooks.com from Jekyll to DocPad, in case they might be of use.
Finally, no discussion of CoffeeScript and static site generators is complete without mentioning Jeremy Ashkenas' small but delightful Journo. In just a single file of code-within-documentation Literate CoffeeScript, Journo provides a everything you need for a minimalist tool, including deploys via rsync.
