Fabric.js Group borderDashArray Property

  • Last Updated : 01 Feb, 2021

In this article, we are going to see how to set the borderDashArray of a Group canvas using Fabric.js. The Group in Fabric.js is movable and can be stretched according to requirements. Further, the Group can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

Approach: To make it possible we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag that will contain the Group. After this, we will initialize instances of Canvas and Group provided by Fabric.js and set the dash pattern of border of the canvas Group using the borderDashArray property.
