Fabric js.Path paintFirst Property

In this article, we are going to see how to set the paintFirst 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 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 paintFirst of canvas path using paintFirst property.

Syntax:

fabric.Path('path', {
   paintFirst: String
});

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

paintFirst: It specifies if the fill or the stroke is drawn first (one of “fill” or “stroke”).

Below example illustrates the use of Fabric.js Path paintFirst property in JavaScript:
