In this tutorial, we will learn how to get the style of the currently selected text using FabricJS. We can display text on the canvas by adding an instance of Fabric.Text. Not only does it allow us to move, scale and change the dimensions of text, but it also provides additional features such as text alignment, text decoration, line height, which are available through the properties textAlign, underline and lineHeight respectively. We can also find the styles of the current selection using the getSelectionStyles method.
