Change size of HTML5 canvas drawings but maintain canvas dimensions

Question

Here is the scenario:

• Suppose the dimensions of the canvas element is set to a max height and max width and obviously does not occupy the entire screen
• We can make drawings made in the canvas larger on events:

   function onMouseMove(e)
   { 
      e.preventDefault();
      if (pinching) {
         resizeDrawings();
      }  
   }
   function resizeDrawings();
   {
     //stuff happens
     const context = currentCanvas.current.getContext('2d');
     //canvas operations

   }

Basically, i want the canvas to overflow and become scrollable if its own contents become too big to fit on it's own dimensions.
