Developing Web apps

Documentation about the core technologies used to create Web apps, including the DOM and WebAPIs.

Key DOM APIs

XMLHttpRequest: Sending and receiving data using HTTP and HTTPS: XMLHttpRequest is the DOM API used to send and receive information using HTTP, including for downloading files.
DOM events: The event reference provides a complete list of all the events that can be sent and received to interact with DOM objects.
Touch events: This documentation covers touch events in particular, which of course you are likely to encounter when developing apps for touchscreen devices.
IndexedDB: A database for Web apps; this provides a great way to store structured data on the user's device.
Storage: The Storage API provides a way to store small amounts of data on the user's device. This is often used for app preferences, for example.

App permissions: A guide to permissions an app needs to perform given tasks, and which permissions different kinds of content and apps get by default, or can request.
Camera API: The camera API lets you snap photos and video using the device's built-in camera.
Optimizing startup performance: Suggestions for ensuring that your app starts up quickly, smoothly, and with minimal apparent impact on device performance and functionality.
WebAPI: The "WebAPI" suite of APIs provide access to nearly all the capabilities of the device, from files to network information.

Note: We will list the individual WebAPI links here directly instead of the landing page soon.
