Fabric.js Path objectCaching Property

Last Updated : 25 Jan, 2021

In this article, we are going to see how to set the objectCaching property of a Path using Fabric.js. The Path in Fabric.js is movable and can be stretched according to requirement. Further, the Path 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 HTML5 canvas HTML5 canvas library called Fabric.js.
After importing the library, we will create a canvas block in the body tag that will contain the path.
After this, we will initialize instances of Canvas and Path provided by Fabric.js and set the objectCaching of canvas path using objectCaching property.

Syntax:

fabric.Path('path', {
   objectCaching: boolean
});

Parameters: This function accepts a single parameter as mentioned above and described below:

objectCaching: When it is set to `true`, the object is cached on an additional canvas. When set to `false`, then the object is not cached unless necessary (clipPath). Default is set to true.

The below example illustrates the use of Fabric.js Path objectCaching property in JavaScript:
