The following example covers how to set the strokeLineCap of a Path using Fabric.js. The Path in Fabric.js is movable and can be stretched according to requirements. Further, the Path can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

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 path. After this, we will initialize instances of Canvas and Path provided by Fabric.js and set the strokeLineCap color of the canvas of the path using strokeLineCap property.


fabric.Path('path', {
   strokeLineCap: String

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

  • strokeLineCap: It specifies whether to set the stroke line cap or not.The accepted values of this parameter are butt, round, and square.

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



<!DOCTYPE html>
    <!-- FabricJS CDN -->
    <div style="text-align: center;width: 400px;">
        <h1 style="color: green;">GeeksforGeeks</h1>
        <b>Fabric.js | Path strokeLineCap Property</b>
    <div style="text-align: center;">
        <canvas id="canvas" width="400" height="200"
        style="border:1px solid green;">
        // Initiate a Canvas instance
        var canvas = new fabric.Canvas("canvas");
        var geek = new fabric.Path('M 0 0 L 100 100 L 0 100 z', {
            fill: '',
            strokeLineCap: "butt",
            stroke: 'red'
