Kendo UI is everything you need to build sites and apps with HTML5 & JavaScript. Kendo UI Core is the free and open-source version of Kendo UI that provides access to the web's best UI widgets and key framework features, essential for developing great experiences for the web and mobile.

Kendo UI Core is a free and open-source subset of Kendo UI. The following table details the widgets and features available in Kendo UI Core, as well as the additional features available via a commercial Kendo UI license.

Kendo UI Core depends on the following libraries:

• jQuery v1.9.1+

Kendo UI Core has not been tested against any other versions of these libraries. You may find that versions other than these are compatible with Kendo UI Core. However, we make no claims to support those versions, and will not troubleshoot issues that arise when using those versions.

There are two ways to get the source code for Kendo UI Core. You can either download a pre-built zip fromTelerik.com, or build the source yourself using Gulp. The latter approach includes an option for building a distribution of Kendo UI Core that includes only the widgets and framework features required by your app.

In order to build Kendo UI Core, you need to haveNode.js 14.x andgit 2.x.

For Windows you have to download and installGit for Windows andNode.js andVisual C++ Build Tools.

Mac OS users should installHomebrew. Once Homebrew is installed, runbrew install git to install git, andbrew install node@14 to install Node.js.

Linux users can use thedistributions provided by NodeSource or their package managers to installgit andnodejs.

Clone a copy of the repository by running

git clone https://github.com/telerik/kendo-ui-core.git

Enter the repository directory

cd kendo-ui-core

Initialize the submodule repository

git submodule update --init

Install dependencies:

npm install

Run the build script:

npm run build

The minified version of the scripts and styles of Kendo UI Core will be put in thedist/ subdirectory.

There are several other tasks available:

npx gulp --tasks

The gulpcustom task will create a custom minified file -dist/kendo.custom.min.js, which includes only the specified components. The following command will include only the autocomplete and dropdownlist widgets:

npx gulp custom -c autocomplete,dropdownlist

The npm scriptnpm run scripts:modules will create two folders (cjs andesm) in thedist folder, which includes the bundled modules.

• Run the dev script in order to compile both modules and js files indist/dev anddist/mjs folder

  npm run scripts:dev ornpm run scripts:dev -- -w

• Run the tests by runningnpx gulp tests

If you want to skip building Kendo UI Core yourself, head on over toTelerik.com to grab the full source.

You can also easily include Kendo UI Core in your site or application by using the Kendo CDN:

<linkhref="http://kendo.cdn.telerik.com/2014.2.716/styles/kendo.common.min.css"rel="stylesheet"/><linkhref="http://kendo.cdn.telerik.com/2014.2.716/styles/kendo.default.min.css"rel="stylesheet"/><scriptsrc="http://kendo.cdn.telerik.com/2014.2.716/js/jquery.min.js"></script><scriptsrc="http://kendo.cdn.telerik.com/2014.2.716/js/kendo.ui.core.min.js"></script>

The main advantage of the CDN approach is that your users may be able to leverage a primed cache version of Kendo UI Core if they've visited other sites using the framework.
