Installation

Knockout’s core library is pure JavaScript and doesn’t depend on any other libraries. So, to add KO to your project, just follow these steps:

  1. Download the latest version of the Knockout JavaScript file from the downloads page. For normal development and production use, use the default, minified version (knockout-x.y.z.js).

    For debugging only, use the larger, non-minified version (knockout-x.y.z.debug.js). This behaves the same as the minified version, but has human-readable source code with full variable names and comments, and does not hide internal APIs.

  2. Reference the file using a <script> tag somewhere on your HTML pages.

For example,

<script type='text/javascript' src='knockout-2.0.0.js'></script>

… and now you’re ready to use it. (Obviously, update the src attribute to match the location where you put the downloaded file.)

If you’re new to Knockout, get started with interactive tutorials, see some live examples, or dig into documentation about observables.
