What is `cdk` in Angular Material 2 components

Question

In multiple places within angular material source, there are elements/ css classes that have cdk as their prefix.

Does anyone know what the abbreviation for cdk in angular material context?

Answer 1

Stands for Component Dev Kit. The CDK allows you to use features that do not depend on Angular Material and its styling and is fully independent. Some awesome features that you can use are Drag and Drop and Virtual scrolling (which I love personally) by just importing the cdk. Check the documentation out here.

Answer 2

CDK => Component Development Kit

It's main purpose is to enable extensible so as to create custom components on top of it.

Answer 3

CDK is the short form of component dev kit. This signifies that these are general-purpose tools for building components that are not coupled to Material Design

From the material2 changelog

• Several components in core/, such as Overlay, have had their prefix changed to cdk- (short for "component dev kit"). This signifies that these are general-purpose tools for building components that are not coupled to Material Design.The old selectors are still available as deprecated but will be removed in the next release. The CSS classes have been changed.

Answer 4

CDK (Component Development Kit) is a standalone package.

The goal of the CDK is to give developers more tools to build awesome components for the web. This will be especially useful for projects that want to take advantage of the features of Angular Material without adopting the Material Design visual language.
