A real-time, data-driven platform for reporting live events on the Web.
- A platform for reporting live events, with a focus on displaying data and information in accessible ways.
- Function as a live CMS. Dynamically populate content areas on an event page for the viewers.
- Establish events as core functionality. A public-facing page on Datajam corresponds to an event. Events are created, produced, and ultimately archived.
- Embed events on third-party sites.
- Comprehensively track metrics for events.
Dependencies and Installation
After those external dependencies are installed, the app can be installed with:
$ rvm use 1.9.3 $ gem install bundler $ git clone https://github.com/sunlightlabs/datajam.git $ cd datajam/ $ bundle install --binstubs $ bin/rails start
Bundler takes care of installing all the other Ruby libraries used by Datajam, and the JS libraries are included in the project. But it's still important to know about them:
- Mongoid as an object mapper to MongoDB
- Jammit for static asset packaging
- Rocco for literate programming
Datajam is intended to be reused and extended by third parties. As such, certain development guidelines are strictly enforced:
- Unit test coverage for all files in
- Acceptance test coverage for all user stories with Capybara.
- All new source files produced (
.js) follow literate programming via Rocco.
Datajam consists of three pieces:
- Front-end: Public-facing part of the app. Presents a view of the event as defined by the back-end. The home page displays the current event (or a message announcing the current event). Alternate views of the current event are available to third parties via the embed mechanism. Archive pages display past events.
- Back-end: Administrative area that reporters use. Includes the interface for creating and editing events. Powers the front-end by defining templates for the event views.
- Content Plugins: Define a data model and provide UI elements for the back-end and front-end. Both the back-end and front-end are architected to provide hooks for the plugins. Content plugins define specific implementations of content areas for the front-end, and administrative functionality in the back-end.
Custom Content Plugins
Datajam ships with three content plugins: Data Card, Live Chat, and Tweet Stream, which are implemented through Rails Engines. Custom plugin development is possible via hooks provided by Datajam.
More documentation coming soon.
