Fabric JS Text Centering

Hello I need a skilled developer with experience in Fabric JS to help me center the text on Canvas. Now, for example, there is a variable whose value is either : 1. Automatic 2. Shorten 3. Line Break. - If the value is "Automatic" make the font size auto. I mean whatever the text length it is, make it in one line by setting the font size. - If the value is "Shorten" then font size should be the default font size and if the text length is bigger than the wrapper, then cut the text from the end. I mean for e.g. the text is "Hello there how are you ? I am fine.". This is long text, but of course, this long text will not fit in the wrapper in one line, right ? So, cut this text from end based on available space on the wrapper (red background box) - If the value is "Line Break" then break the line if it's bigger than the wrapper. If you can do this then download the uploaded zip file, run it, and show me the output. I will hire you instantly. After successfully installing all the packages, run it on your browser - localhost/generateimage and then you can see the result. Thanks.
