Mobile UI Elements is a free, open-source Force.com (unsupported) library to simplify the development of mobile apps. The library, based on the Google’s Polymer framework, provides the fundamental building blocks for creating HTML5 apps that run well on smartphones and tablets. The elements can be mixed together to create fairly complex force.com applications and the apps can be deployed in the browser or embedded inside Container from the Salesforce Mobile SDK.
Note: The library is still in heavy development and is missing certain features as well as complete documentation.
This document is intended to introduce you to the app's architecture and design and make it as easy as possible for you to jump in, run it, and start contributing.

What is it?
Mobile UI Elements is a set of web components built using Google’s Polymer framework. The library utilizes the future of HTML5 standards, such as Custom Elements, ShadowDOM, Templates, HTML imports etc., to provide a set of new HTML tags that generate the Saleforce driven UI for your mobile application. It's built on top of Salesforce Mobile SDK and extends the open source frameworks such as Backbone.js and Undescore.js and JQuery. It also comes with some stylesheets, providing the responsive design for tablets and phones, and Sample Apps to showcase how to use them in a real application. You can easily combine and extend this library to develop UI specific to your application.
$ git clone https://github.com/ForceDotComLabs/mobile-ui-elements.git
$ cd mobile-ui-elements
$ npm install
$ bower prune (Do this if you are updating an old copy of mobile-ui-elements to remove core-bind dependency.)
$ bower install
To build the project, execute:
$ grunt
To build the project for distribution, execute (all assets will be generated in dist directory):
$ grunt dist
Run a local node server:
$ node proxy.js
You can now launch the Sample App. It will go through the OAuth flow to obtain user session and render data.
To create a mobile sdk app, run the following command. Make sure that the forceios tool is already installed:
$ grunt create_app
Available UI Elements
force-signin: This element allows an easy way to initiate OAuth into salesforce via web or mobile SDK.
Supported attributes include:
auto: (Optional) Automatically trigger user authentication as soon as the component is ready. If accesstoken and instanceurl are set via attributes, OAuth will not trigger automatically.
consumerkey: (Optional) Consumer key for initiating OAuth based salesforce authentication. It's required only for web based applications. For SDK based applications, specify the consumer key in the bootconfig.json.
callbackurl: (Optional) Callback URL property for OAuth based authentication. It's required only for web based applications. For SDK based applications, specify the callback URL in the bootconfig.json.
loginurl: (Optional) Login Host for salesforce authentication. It's required only for web based applications. For SDK based applications, specify the login host in application settings. Default value is https://login.salesforce.com
proxyurl: (Optional) Custom proxy host setting for web based application. If specified, all the HTTP requests will be sent to this proxy host with "Salesforce-Endpoint" header for actual host URL. This allows cross-domain calls restricted by browsers.
usePopupWindow: (Optional) Set as true if you want OAuth flow to be started in a new child window.
accesstoken: Salesforce session ID for API requests. It is set by the component after successful completion of Salesforce OAuth.
instanceurl: Salesforce instance URL for API requests. It is set by the component after successful completion of Salesforce OAuth.

sync: when the collection has been successfully synced with the server
error: when a request to remote server has failed.
force-sobject: This element provides a custom component for Force.SObject from Mobile SDK's SmartSync JS. It allows apps to easily perform CRUD operations against a salesforce sobject in both online & offline modes.

force-ui-app: This element is a top level UI element that provides the basic styling and structure for the application. This element uses polymer layout features to enable flexible sections on the page. This is useful in single page view with split view panels. All the children of the main section must have the class "content" specified on them to apply the right styles.

FAQ
Polymer is still "alpha" project. How should I use it?
Polymer as an overall project is still a work in progress. We feel that the underlying platform code leveraged for UI Elements is stable enough to start creating new apps for learning and prototyping purposes. Polymer will continue to be tweaked as the Web Components standard reaches its final stage. Various building blocks of Web Components, including Shadow DOM, are now natively supported in Chrome. This enables better performance for your mobile applications.
Polymer doesn't work inside the WebView on Android below 4.4
This is limitation of the older version of WebKit used for the WebView on pre 4.4 devices. Polymer does work in the Android Mobile browsers along with all of the popular evergreen browsers. If Android WebView is a real limitation, please let us know.
Does it work with other devices?
We got our samples to work on IE10 running on Windows Mobile, Safari on iOS6/7, Chrome, Safari, and Firefox
What's the level of support for this project?
Mobile UI Elements is an unsupported project. It's a way for us to share our code with the community that might be beneficial for certain use cases. We'd love to build a vibrant community for this project. A lot depends on the level of interest.
I don't see any data show up in my components
Please check the JavaScript console to be sure of the error. You might not be getting the data because your session has expired. If that's the case get a new session id. Or you might have enabled cross-domain scripting in Chrome or your other browser.
