Prototype mobile apps with simple HTML, CSS and JS components.

Getting Started

  • Clone the repo git clone or just download the bundled CSS and JS
  • Read the docs to learn about the components and how to get a prototype on your phone
  • We will have example apps to check out very soon!

Take note that our master branch is our active, unstable development branch and that if you're looking to download a stable copy of the repo, check the tagged downloads.


Ratchet was developed to support iOS 5+ for iPhone. Questions or discussions about Ratchet should happen in the Google group or hit us up on Twitter @goRatchet.

A small list of "gotchas" are provided below for developers starting to work with Ratchet

  • Ratchet is designed to respond to touch events from a mobile device. In order to use mouse click events (for desktop browsing and testing), you have a few options:
    • Enable touch event emulation in Chrome (found in the overrides tab in the web inspector preferences)
    • Use a javascript library like fingerblast.js to emulate touch events (depending on the user agent)
  • Script tags containing javascript will not be executed on pages that are loaded with push.js. If you would like to attach event handlers to elements on other pages, document-level event delegation is a common solution.

Future features

Ratchet is just getting started. Here are some of the immediate features we're thinking about:

  • Shelf (exposable left hand navigation a la Path or Facebook)
  • Gridviews
  • Notifications
  • Slide control
  • More list views options
  • Improved active states (especially for lists)
  • Docking list dividers
  • Touch library for richer touch events (swipes, long press, etc)
  • Autocomplete
  • Hiding title bar (hides with scroll)

Even these are just the short-term goals though. We eventually want to extend Ratchet beyond the prototying for iPhone and create HTML/CSS/JS components for iPad and Android devices. Our dream is that Ratchet becomes the best way to create mobile experiences with web standard languages.
