canvas text wrapped buffer thing using the https://github.com/namniak/canvas-text-wrapper library

canvasText.js

function renderToCanvas = function (width, height, renderFunction, canvasParam) {
	    var buffer = document.createElement('canvas');
	    buffer.width = width;
	    buffer.height = height;
	    if (canvasParam) {
	    	var ctx = buffer.getContext('2d');
	    	for (var i in canvasParam) {
	    		ctx[i] = canvasParam[i];
	    	}
	    }
	    renderFunction(buffer);
	    return buffer;
};

var renderText = function (canvas) {
			CanvasTextWrapper(canvas, text, options); // Look up CanvasTextWrapper options in their doc https://github.com/namniak/canvas-text-wrapper
	 };
var buffer = utils.renderToCanvas(width, height, renderText, canvasOptions); // Generates a canvas of the size we want to allow for the text and renders the text in it

// in sharing code

ctx.drawImage(buffer, 100, 100); // Renders generated canvas buffer to our main sharing canvas
