Nesta: Heroku-friendly Sinatra-based CMS now a Ruby gem, gets new site

We’re big fans of open source publishing tools. Although Tumblr has been a good way to bootstrap this blog, we have a dream to move on to something with a bit more publishing oomph. Thanks to Graham Ashton, NestaCMS is looking to be the future platform for The Changelog. Nesta is now a Ruby gem and has a shiny new web site.

For those not familiar with Nesta, it’s a bit like Nanoc or Jekyll, but instead of generating 100% pure static pages, it relies on HTTP cache to get the best of both worlds, dynamic content and static delivery. Geoffrey Grosenbach uses a custom Nesta setup to power the Peepcode blog.


If you’re not a designer, the default Nesta theme includes the basic design elements of a good blog or web site:

  • Semantic HTML5
  • Clean typography
  • Easy to extend or embed
  • Write content in Markdown, Textile, or Haml
  • Support for Google Analytics, Atom feeds, comments (via Disqus), XML sitemaps…

Installation and creating a project

Now that Nesta has been gemified, your project only needs to worry about content and templates, all the Nesta plumbing is provided by the gem. To start, install the gem:

gem install nesta

Now we have a nesta command line interface:

» nesta

    --help, -h            Display this message.

    new <path>            Create a new Nesta project.
    demo:content          Install example pages in ./content-demo.
    theme:install <url>   Install a theme from a git repository.
    theme:enable <name>   Make the theme active, updating config.yml.
    theme:create <name>   Makes a template for a new theme in ./themes.

    --git                 Create a new git repository for the project.
    --vlad                Include config/deploy.rb.

To create a new site, just type:

nesta new my_cool_blawg

This unfurls a basic Sinatra-powered Rack app with a folder for your content:

my_cool_blawg » ls -la                                 ~/Projects/sandbox/my_cool_blawg  
total 16
drwxr-xr-x   6 wynn  staff  204 Feb 18 08:41 .
drwxr-xr-x  11 wynn  staff  374 Feb 18 08:41 ..
-rw-r--r--   1 wynn  staff  116 Feb 18 08:41 Gemfile
drwxr-xr-x   3 wynn  staff  102 Feb 18 08:41 config
-rw-r--r--   1 wynn  staff  175 Feb 18 08:41 config.ru
drwxr-xr-x   4 wynn  staff  136 Feb 18 08:41 content

You can add some dummy content as well:

nesta demo:content

Now you can crank up nesta with Shotgun (or Passenger, etc.):

shotgun config.ru

… and browse to your site on [http://localhost:9393]


What we love about Nesta is the front matter, or metadata you can drop into each file for arbitrary bits of info. Here’s how we’re using it in our upcoming blog rewrite:

# WebFont Loader - easy @font-face from Google, TypeKit, or your own site

Thanks to greater browser support for [@font-face](http://www.font-face.com/#lime_content), web typography is breaking free from the same boring font stacks we've known for the last ten years. As with any new technique, @font-face introduces new challenges for finding the right cross-browser syntax, especially to avoid things like Firefox's [Flash of Unstyled Text](http://paulirish.com/2009/fighting-the-font-face-fout/) issue.


This allows you to fully customize how you serve up your content, even specifying per-post templates or layouts.


Nesta also has great theme support. You can create your own theme:

theme:create <name>   #Makes a template for a new theme in ./themes.

… or install from a url:

theme:install <url>   Install a theme from a git repository.

Heroku friendly

Since Nesta plays nice with Heroku’s readonly filesystem, its a great cheap (or free) way to host a blog or any content-heavy site.

Outsource your content to Nesta

Another great fit for Nesta is as a mountable site inside another Rack application. You can easily have Nesta power your blog inside your Rails application:

MyApp::Application.routes.draw do
  mount MyHawtBlawg.new => "/blog"
  # other rails routes

Nesta has a growing community. Be sure and join the mailing list, follow on @NestaCMS on Twitter, or join us in #nesta on IRC.
