Manually set bounding box for text object in fabricjs canvas

Question

When I add a text object to my canvas using fabricJs, the bounding box is automatically calculated based on the size of the text rendered. Is there a way to manually set the coordinates of the bounding box?

For example, I can place text using the following

var text = new fabric.Text('hello world', { left: 100, top: 100 });
canvas.add(text);

But the bounding box is calculated automatically. What if I wanted a very wide box with right-aligned text? I'd like to do something like this:

var text = new fabric.Text('hello world', { left: 100, top: 100, width: 500, textAlign: "right" });
canvas.add(text);

But the width appears to be ignored and the text appears aligned at the (100,100) position instead of to the right.

If I understand you correctly, then you can try using TextBox with the editable: false parameter instead of Text. Example below:

const canvas = new fabric.Canvas('demo');

const textBox = new fabric.Textbox('Popular greeting:\n "Hello World"', {
  width: 250,
  top: 50,
  left: 50,
  fontSize: 22,
  textAlign: 'right',
  fixedWidth: 250,
  padding: 2,
  editable: false
});

canvas.add(textBox);

#demo {
  background-color: grey;
  margin-top: 10px;
  border: 1px solid #000000;
}
