Telerik, a manufacturer of developer tools such as Kendo UI and RadControls, has released version 4 of its tool for developing user interfaces (UI) KendoReact. The commercial library is aimed at React developers and consists of UI and data visualization components.

The new features of KendoReact include, among others support for Facebook’s open source JavaScript library React 17, which was only released this week, and an update of the display options for the Avatar component. Developers can add KendoReact packages to their applications via the package manager npm.

License key required One of the main innovations is that KendoReact Now with the fourth major version, all users (test users as well as developers with a license) asks to enter a license key when adding the library to their React projects. The browser issues a warning message for this in the console.

The key can be obtained on the one hand by registering for a free trial version or on the other hand by purchasing a license. The blog post on the announcement offers detailed instructions for activation.
