Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will see Angular PrimeNG Splitter Events.

The Splitter Component allows a user to split two-element using a splitter & utilized it separately and resize panels.

Angular PrimeNG Splitter Events:

onResizeStart: It is a callback that is fired when resizing starts.
onResizeEnd: It is a callback that is fired when resizing ends.

Syntax:

<p-splitter (event)=function()>
    ...
</p-splitter>

Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

Step 3: Install PrimeNG in your given directory.
