Is it possible to save all canvas objects to a text file?

Question

JavaScript

Is it possible to save the coordinates of objects (i.e. lines, pictures, shapes) canvas to a text file, so that later, when opening this file, continue editing?

Answer 1

Canvas elements are more abstract. Unlike decorative svg, they are not elements, but program code.
But you can save it in json format (for example), when canvas is loaded, send a json request to this file, parse it into an object, and take coordinates from it.
