* In fixing funcunit to work for HTML5 drag and drop, we unfortunately broke it for jQuery drag drop. The reason for this is that HTML5 stops sending mouse events and starts sending _drag_ events when a drag begins on a _draggable_ object. jQuery draggables do not necessarily have that attribute. We now check for that attribute, send the drag events if its draggable, and we just send mousedown, moves, and ups if its not a draggable

* Slight correction - reordering some functions to avoid jshint complaining

* Removed jquery-ui and moved it to npm_modules at Chasen's request

If you are looking for the Synergy project, you can find it here. Thanks postquagga for letting us use the name!

Syn lets you simulate user behavior like typing, clicking, moving, and dragging exactly how a real user would perform those actions. 'hello' )
   .type( 'Hello World' )
   .drag( 'trash' );


Install Syn via the command line with npm:

> npm install syn

or bower:

> bower install syn

Or by downloading it here.

Inside the download, npm package and bower package, there are the following folders:

  • dist/global/syn.js - A standalone file that can be used with a <script> tag.
  • dist/amd - An AMD build that can be used with RequireJS and other AMD loaders.
  • dist/cjs - A CommonJS build that is used by node or browserify.
  • src - The source files that can be loaded by StealJS, SystemJS, and eventually JSPM.


The following walk you through how to load Syn into various environments.

Node / Browserify

Assuming you installed with npm, simply require("syn") like the following:

var syn = require("syn");'hello'));


If you installed via NPM or Bower and are using the npm or bower module for configuration, you can use import, require, or define to load the syn module without any configuration.

import syn from "syn";'hello'));

AMD / RequireJS

Add the following package configuration:

    packages: [{
        name: 'syn',
        location: 'PATH/TO/syn/dist/amd',
        main: 'syn'

PATH/TO should be the path from your baseUrl to the location of the syn folder. Once this is properly configured, you should be able to write:

define(['syn'], function(syn){'hello'));

Script Tag / Standalone

If you don't use a module loader, you can simply add the following to your page:

<script src='PATH/TO/dist/syn.js'></script>

PATH/TO should be the path to the installed syn folder.

Use element [, options][, callback] )

syn.dblclick( element [, options][, callback] )

syn.type( element, text [, callback] )

syn.key( element, key [, callback] )

syn.delay( time=600 )

syn.drag( element, optionsOrTarget [, callback])
