From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

Create a Meteor app and put the client_/server_ files in a client/server directories. Also, create a public dir to save the uploaded files.

	game = {}
	game.button= ""
	game.key = ""

	function love.load()
	success = love.graphics.setMode(320, 240, false, 0)
	end

	function love.update(dt)
	end

	var fs = require('fs'),
	decode64 = require('base64').decode;

	var data = fs.readFileSync('./encode.png', 'base64');
	var buffer = new Buffer(data, 'base64');

	fs.writeFileSync('./decode.png', decode64(buffer), 'binary')

	function love.load()
	rect = {
	x = 100,
	y = 100,
	width = 100,
	height = 100,
	dragging = { active = false, diffX = 0, diffY = 0 }
	}
	end

	<?php
	define('WYSIWYG_META_BOX_ID', 'my-editor');
	define('WYSIWYG_EDITOR_ID', 'myeditor'); //Important for CSS that this is different
	define('WYSIWYG_META_KEY', 'extra-content');

	add_action('admin_init', 'wysiwyg_register_meta_box');
	function wysiwyg_register_meta_box(){
	add_meta_box(WYSIWYG_META_BOX_ID, __('WYSIWYG Meta Box', 'wysiwyg'), 'wysiwyg_render_meta_box', 'post');
	}

	/* This element holds injected scripts inside iframes that in some cases may stretch layouts. So, we're just hiding it. */
	#fb-root {
	display: none;
	}

	if (Meteor.is_client) {
	var userName = "PatelNachiket";
	Template.hello.greeting = function () {
	return "Fetch recent tweets from Twitter stream of user : " ;
	};

	Template.hello.events = {
	'click #fetchButton' : function () {
	console.log("Recent tweets from stream!");
	$('#fetchButton').attr('disabled','true').val('loading...');
