How to change the font style of a text canvas using Fabric.js ?

In this article, we are going to see how to change the font style of a text canvas using FabricJS. The canvas means text written is movable and can be stretched according to the requirement. Further, the text itself cannot be edited like a textbox.

Approach: To make it possible we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the fontStyle property to change the font style and render the Canvas on the Text as given in the example below.


fabric.Text(text, fontStyle: number); 

Parameters: This function accepts two parameters as mentioned above and described below:

  • text: It specifies the text to be written.
  • fontStyle: It specifies the font style which can be normal, oblique or italic where normal is the default style.

Program: This example uses FabricJS to change font style of a text canvas.
