This page lists all API specifications that are defined or referenced/used within the webinos project.

The APIs listed here are to be considered 'work in progress'. The official stable webinos API specifications are located at

webinos is exposed under the window.webinos object. The webinos Core Interface, the webinos Discovery API and a few more webinos APIs are available directly under this name space.

However, one of the key elements of webinos is that the framework provides means to bind to a service object in a remote execution environment. The webinos Discovery API defines how a service is discovered and how an application can bind to a remote service. The service object will act as proxy for sending/receiving events to/from the remote peer and hides the complexity of sending/receiving message between the peers in a trusted manner. This mechanism is not limited to webinos defined APIs but is also available for the APIs defined by W3C referenced below and also to user defined APIs.

Most webinos APIs defines services that are discoverable through the webinos Discovery API and are therefore not exposed directly under the window.webinos object. Instead these APIs inherit the general webinos Service Interface that is defined in the webinos Discovery API

The Github repository for the webinos API specifications source files is Github webinos API specifications.

Referred APIs used by webinos

SpecificationSummaryInheritance of webinos Service interfaceFeature URI
The W3C DeviceOrientation Event specification

This specification defines several new DOM event types that provide information about the physical orientation and motion of a hosting device.

interface DeviceOrientation : Service {
The W3C File API

This specification provides an API for representing file objects in web applications, as well as programmatically selecting them and accessing their data.

N/A (all file APIs) (file read only)
The W3C File API: Writer

This specification defines an API for writing to files from web applications. This API is designed to be used in conjunction with, and depends on definitions in, other APIs and elements on the web platform such as the W3C File API.

N/A (all file APIs) (file write only)
The W3C File API: Directories and System

This specification defines an API to navigate file system hierarchies, and defines a means by which a user agent may expose sandboxed sections of a user local filesystem to web applications. It builds on the File Writer API, which in turn built on the File API, each adding a different kind of functionality.

interface LocalFileSystem : Service {

interface LocalFileSystemSync : Service {
}; (all file APIs)
The W3C Geolocation API

This specification defines an API that provides scripted access to geographical location information associated with the hosting device.

interface Geolocation : Service {
The W3C Media Capture and Streams API

This specification defines an API that provides access to the audio, image and video capture capabilities of the device.

interface NavigatorUserMedia : Service {

This specification defines an API that allows to establish peer-to-peer connections between browsers, and transmit media streams and data over these connections.
