Kendo UI Core

About Kendo UI Core

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.

Features of Kendo UI Core

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.

Compatibility and Requirements

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.

Building Kendo UI Core

There are two ways to get the source code for Kendo UI Core. You can either download a pre-built zip from Telerik.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.

Installing Dependencies

In order to build Kendo UI Core, you need to have Node.js 14.x and git 2.x.

For Windows you have to download and install Git for Windows and Node.js and Visual C++ Build Tools.

Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node@14 to install Node.js.

Linux users can use the distributions provided by NodeSource or their package managers to install git and nodejs.

How to build Kendo UI Core

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

Run the build script:

npm run build

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

There are several other tasks available:

npx gulp --tasks

Building only what you need

The gulp custom 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

Building ESM and CJS modules

The npm script npm run scripts:modules will create two folders (cjs and esm) in the dist folder, which includes the bundled modules.

Development

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

  npm run scripts:dev or npm run scripts:dev -- -w

• Run the tests by running npx gulp tests

Using Kendo UI Core via the Kendo Static CDN

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

<link href="http://kendo.cdn.telerik.com/2014.2.716/styles/kendo.common.min.css" rel="stylesheet" />
<link href="http://kendo.cdn.telerik.com/2014.2.716/styles/kendo.default.min.css" rel="stylesheet" />
<script src="http://kendo.cdn.telerik.com/2014.2.716/js/jquery.min.js"></script>
<script src="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.
