iamappmaker commented 4 years ago

I created a graphic design application using fabricjs. only thing i worried is performance. When i add HD image and do any operations, performance drops and most of the time getting hang. So i like to migrate to konva but we have many json files, is it possible to convert fabric json to konva json format so i can import my fabricjs projects.

Before migration makes sure Konva can provide better performance. Personally I am not sure about it, because fabric and Kovna work very similar. I think you can try to decrease image resolution in some cases.

I don't know the fabric format and what properties they use. But you can try to do it. Just compare them manually and write your own converter.

Any way for storing objects it is better to use your own JSON format, so it independent from the framework.
