[] (http://wq.io/wq.app)

wq.app is a suite of Javascript modules and related assets, created to facilitate the rapid deployment of offline-cabable HTML5 mobile and desktop data collection apps for crowdsourcing, citizen science, and volunteered geographic information, as well as professional field data collection. wq.app is the client component of the wq framework, and can be used with any REST service. When combined with a Mustache-capable REST service like wq.db, wq.app can be used to create progressively enhanced websites / apps, that can selectively render individual application screens on the server or on the client depending on project needs, network connectivity, and localStorage availability.

Project Layout

wq.app/js is built on a number of libraries including RequireJS, jQuery Mobile, Leaflet, d3, and Mustache.js. wq.app extends these libraries with:

• store.js, a robust localStorage-cached JSON REST client (with a lightweight implementation of models and collections)
• pages.js, a PJAX-style pushState URL router, template renderer, and page injector
• app.js, a high-level application controller that combines store.js and pages.js into a full configuration-driven CRUD client (intended for use with wq.db's app.py)
• map.js, Leaflet integration for app.js models that contain geometry (GeoJSON or simple lat/long)
• chart.js, configurable d3-based time series and contour plots
• and a number of other useful utilities

When using wq.app in the recommended project layout, wq.app/js should be mapped to myproject/app/js/wq.

wq.app/css includes the default stylesheets packaged with jQuery Mobile and Leaflet. When using wq.app in the recommended project layout, wq.app/css should be mapped to myproject/app/css/wq.

wq.app/scss provides a SASS/SCSS stylesheet for use with Compass, with appropriate macros for generating custom jQuery Mobile themes.

wq.app/util provides a Python-based build process for compiling wq apps: inlining templates, optimizing code (via r.js), and generating an application cache manifest.

wq.app does not currently include any default HTML templates, leaving this as an exercise for the project implementer.
