can-vdom

module

A browser-lite environment for Node.js or a worker thread.

`undefined`

The can-vdom module does not export anything, but it changes the current environment to have the limited subset of browser environment behavior and functionality needed to support CanJS templates and other behavior without a native DOM.

require("can-vdom");

window === global; // true

document.getElementsByTagName("body"); // [HTMLBodyElement]

can-vdom decorates the environment global to include:

a non-functional navigator, location, and history object.
a limitedly functional document with basic Node behavior, event binding and dispatching.

Shiming a browser environment

Importing can-vdom will shim a browser-like environment into Node's globals. Use this approach to run code that expects a global window and/or document object.

require("can-vdom");

typeof window; // "object"

typeof window.addEventListener; // "function"

document.getElementById("foo"); // undefined

Loading as a module

If you want to prevent setting globals you can load can-vdom/make-window/make-window directly:

var makeWindow = require("can-vdom/make-window/make-window");

var myWindow = makeWindow(global);
