Mascara includes some useful interface-definition files. By importing these definitions, you get compile-time verification and code completion help.

Browser provided interfaces

These files contains definitions of types which are available in the browser.

browserapi

defines the main objects available in the browser: window, document and so on. Note: the declarations are just for proof-of-concept, and is not yet the full API as defined by WHATWG and W3C.

htmldom

The full W3C HTMLDOM

canvasapi

The WHATWG Canvas drawing API

logging

The console logging interface supported by most browsers

Supported third party libraries

JQuery

Mascara comes with an interface definition file for the very popular JQuery library.

Usage

The libraries are used by importing them:

import browserapi;
window.alert("hello!");

In the case of third-party libraries like JQuery, you have to ensure that the library is included at runtime via a script tag in the html.
