###Webshot - Meteor Smart Package

This is a the node-webshot npm plugin as a meteor smart package.

###How to install?

1. Install meteorite
2. mrt add webshot

###How to use?

You can use webshot to easily grab screenshots within Meteor. Below is a simple guide to snapping a URL with Meteor, saving the file to a local directory, then optionally prompt the user to download the image using meteor-router and changing the mime type of the page in a server side route.

1. Ensure you have an image directory with a ~ so that the Meteor framework does not reload the app on file change. mkdir public/~exports

2. Use the WEBSHOT plugin in your client code:

    var _image = "myscreenshot.png";
    var _res =  WEBSHOT.snap("http://url_to_capture", "public/exports~/" + _image, {
    		screenSize: {
    			width: 300
    			, height: 300
    		});
   

   See the API documentation for complete list of options

3. Finally, to prompt the user to download the image, you can use meteor-router thusly:

   mrt add router

   Add this server side route (in server code)

    	Meteor.Router.add("/render/:id", "GET", function(_image) {
    		var fs = Npm.require("fs")
    			, Future = Npm.require("fibers/future")
    			, future = new Future
    			, cb = future.resolver();
   
    		fs.readFile("public/exports~/" + _image, cb);
    		var _read = future.wait();
   
    		fs.unlink('public/exports~/' + _image, function (err) {
    		  if (err) throw err;
    		});
   
    		this.response.setHeader("Content-Type", "application/octet-stream");
    		return [_read];
    	});
   

   Once you've called the WEBSHOT.snap (step 2), redirect the user to the server side route to prompt the download:

    	window.location.href = "/render/" + _image;
