By working through the sample codes from the previous post<\/a>, you might have understood the actual benefits of using Node.js. In today\u2019s post, we\u2019ll demonstrate a practical script that clearly shows the use of Node.js in event-based programming.<\/p>\n

We\u2019ll create a simple script that outputs the number of \u201cFacebook likes\u201d for a particular Facebook page. Additionally, we\u2019ll include a feature that updates the number of \u201cFacebook likes\u201d every 2 seconds.<\/p>\n

The output will be simple and plain, probably something like this: \u201cNumber of Likes: 2630405\u201d. You can style it using CSS. Let\u2019s get started!<\/p>\n

To Give You an Idea<\/h2>\n

Before we dive into using Node.js, let\u2019s take a moment to consider what we\u2019d normally do with common server-side programming languages (like PHP). If you are thinking of making an AJAX call to find the number of likes<\/em> every 2 seconds, you are correct. However, this may potentially increase the server overhead<\/strong>.<\/p>\n

\"Example<\/figure>\n

We can consider accessing graph.facebook.com<\/em><\/strong>, which would be a time-consuming I\/O operation<\/strong>. Imagine 5 users accessing the same page that outputs the number of likes<\/em>. The number of accesses to graph.facebook.com<\/em> in 2 seconds will become 10 because everyone will update their number of likes<\/em> once in 2 seconds, and it will be executed as a separate thread<\/strong>.<\/p>\n

\"Example<\/figure>\n

That\u2019s not necessary with a Node.js server implementation. Only one access to the Facebook server is required<\/strong>, and the time to get and output the result (number of likes<\/em>) can be greatly reduced<\/strong>.<\/p>\n

So, how are we going to implement this? That\u2019s what we are going to find out in the sections below.<\/p>\n

Getting Started<\/h2>\n

Before we start, you should have Node.js installed and running on a v8 environment-supported web hosting account<\/strong>. Check out the topics, \u201cGetting started with Node.js\u201d and \u201cInstalling Node.js\u201d in our previous article, Beginner\u2019s Guide to Node.js<\/a> if you haven\u2019t.<\/p>\n

In the server, we access graph.facebook.com<\/code> at an interval of 2 seconds<\/strong> and update the number of likes<\/em><\/strong>. Let\u2019s call this \u201cACTION1<\/strong>\u201c. We will prepare a page so that it will update itself via AJAX every 2 seconds.<\/p>\n

Consider many users accessing the same page. For every user\u2019s AJAX request, an event listener is attached in the server for the completion of \u201cACTION1\u201d<\/strong>. So whenever \u201cACTION1\u201d is completed, the event listeners will be triggered.<\/p>\n

Let\u2019s take a look at the server-side code.<\/p>\n

The code:<\/strong><\/p>\n

\r\nvar facebook_client = my_http.createClient(80, \"graph.facebook.com\");\r\nvar facebook_emitter = new events.EventEmitter(); \r\nfunction get_data() {\r\n    var request = facebook_client.request(\"GET\", \"\/19292868552\", {\"host\": \"graph.facebook.com\"});\r\n    request.addListener(\"response\", function(response) {\r\n        var body = \"\";\r\n        response.addListener(\"data\", function(data) {\r\n            body += data;\r\n        });\r\n        response.addListener(\"end\", function() {\r\n            var data = JSON.parse(body);\r\n            facebook_emitter.emit(\"data\", String(data.likes));\r\n        });\r\n    });\r\n    request.end();\r\n}\r\nmy_http.createServer(function(request, response) {\r\n    var my_path = url.parse(request.url).pathname;\r\n    if (my_path === \"\/getdata\") {\r\n        var listener = facebook_emitter.once(\"data\", function(data) {\r\n            response.writeHeader(200, { \"Content-Type\": \"text\/plain\" });\r\n            response.write(data);\r\n            response.end();\r\n        });\r\n    } else {\r\n        load_file(my_path, response);\r\n    }\r\n}).listen(8080);\r\nsetInterval(get_data, 1000);\r\nsys.puts(\"Server Running on 8080\");\r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
\r\nvar facebook_client = my_http.createClient(80, \"graph.facebook.com\");\r\nvar facebook_emitter = new events.EventEmitter();\r\n<\/pre>\n
We create an HTTP client<\/strong> to access the Facebook Graph API using facebook_client<\/code>. We also need the EventEmitter()<\/code> function, which will trigger when \u201cACTION1\u201d is completed.<\/p>\n
This will become clear in the code described below.<\/p>\n
\r\nfunction get_data() {\r\n    var request = facebook_client.request(\"GET\", \"\/19292868552\", {\"host\": \"graph.facebook.com\"});\r\n    request.addListener(\"response\", function(response) {\r\n        var body = \"\";\r\n        response.addListener(\"data\", function(data) {\r\n            body += data;\r\n        });\r\n        response.addListener(\"end\", function() {\r\n            var data = JSON.parse(body);\r\n            facebook_emitter.emit(\"data\", String(data.likes));\r\n        });\r\n    });\r\n    request.end();\r\n}\r\n<\/pre>\n
Function get_data<\/code> fetches data from the Facebook API<\/strong>. We first create a GET request<\/strong> using the request<\/code> method with the following syntax:<\/p>\n
\r\nClient.request('GET', 'get_url', {\"host\": \"host_url\"});\r\n<\/pre>\n
The number \u201c19292868552<\/em><\/strong>\u201d is the Facebook ID of the page whose details we need to access. So the final page we are trying to access becomes: http:\/\/graph.facebook.com\/19292868552<\/a>. After making the request, we need to add three listeners to it<\/strong>, as follows:<\/p>\n
    \n
  1. Response<\/strong> \u2013 This listener is triggered when the request starts receiving data. Here we set the body of the response to an empty string.<\/li>\n
  2. Data<\/strong> \u2013 As Node.js is asynchronous, the data is received in chunks. This data is added to the body variable to build up the complete response.<\/li>\n
  3. End<\/strong> \u2013 This listener is triggered when \u201cACTION1\u201d specified above is completed. The data returned by the Facebook Graph API call is in JSON format. We convert the string to a JSON object using the JavaScript function JSON.parse<\/code>.<\/li>\n<\/ol>\n
    You can see that a listener is attached for the event_emitter<\/code> object. We need to trigger it at the end of \u201cACTION1\u201d<\/strong>. We trigger the listener explicitly with the method facebook_emitter.emit<\/code>.<\/p>\n
    \r\n{\r\n    \"id\": \"19292868552\",\r\n    \"name\": \"Facebook Platform\",\r\n    \"picture\": \"http:\/\/profile.ak.fbcdn.net\/hprofile-ak-ash2\/211033_19292868552_7506301_s.jpg\",\r\n    \"link\": \"https:\/\/www.facebook.com\/platform\",\r\n    \"likes\": 2738595,\r\n    \"category\": \"Product\/service\",\r\n    \"website\": \"http:\/\/developers.facebook.com\",\r\n    \"username\": \"platform\",\r\n    \"founded\": \"May 2007\",\r\n    \"company_overview\": \"Facebook Platform enables anyone to build social apps on Facebook and the web.\",\r\n    \"mission\": \"To make the web more open and social.\",\r\n    \"parking\": {\r\n        \"street\": 0,\r\n        \"lot\": 0,\r\n        \"valet\": 0\r\n    }\r\n}\r\n<\/pre>\n
    The above represents the response of the Facebook Graph API call. To get the number of likes<\/em>: take the likes object of the data object<\/strong>, convert it to a string<\/strong>, and pass it to the emit<\/code> function<\/strong>.<\/p>\n
    After this action, we end<\/code> the request.<\/p>\n
    \r\nmy_http.createServer(function(request, response) {\r\n    var my_path = url.parse(request.url).pathname;\r\n    if (my_path === \"\/getdata\") {\r\n        var listener = facebook_emitter.once(\"data\", function(data) {\r\n            response.writeHeader(200, { \"Content-Type\": \"text\/plain\" });\r\n            response.write(data);\r\n            response.end();\r\n        });\r\n    } else {\r\n        load_file(my_path, response);\r\n    }\r\n}).listen(8080);\r\nsetInterval(get_data, 1000);\r\n<\/pre>\n
    Creating the server is similar to the previous tutorial with a small change. For every URL (except \/getdata<\/code>), we load the corresponding static file using the load_file<\/code> function<\/strong> we defined earlier.<\/p>\n
    The http:\/\/localhost:8080\/getdata<\/code> is the URL for the AJAX request. In each AJAX request, we attach an event listener to facebook_emitter<\/code><\/strong>. It is similar to addListener<\/code> but the listener is removed after it is emitted to avoid a memory leak<\/strong>. If you need to check it out, just replace once<\/code> with addListener<\/code><\/strong>. We also call the get_data<\/code> function once every second using setInterval<\/code>.<\/p>\n
    Next, we create the HTML page where the output displays.<\/p>\n
    The code:<\/strong><\/p>\n
    \r\n<!DOCTYPE html>\r\n<html>\r\n<head>\r\n    <title>Facebook Likes<\/title>\r\n    <link rel='stylesheet'>\r\n    <script type=\"text\/javascript\" src=\"http:\/\/ajax.googleapis.com\/ajax\/libs\/jquery\/1.4.2\/jquery.min.js\"><\/script>\r\n<\/head>\r\n<body>\r\n    <p>Number of Likes: <b id=\"content_area\">Loading...<\/b><\/p>\r\n    <script type=\"text\/javascript\">\r\n    var content_area = $(\"#content_area\");\r\n    function load_content() {\r\n        $.get(\"\/getdata\", function(data) {\r\n            content_area.html(data);\r\n            load_content();\r\n        });\r\n    }\r\n    load_content();\r\n    <\/script>\r\n<\/body>\r\n<\/html>\r\n<\/pre>\n
    Code Explanation:<\/strong><\/p>\n
    The jQuery AJAX part is pretty self-explanatory. Do check out the call of the load_content<\/code> function. It looks like it runs in an infinite loop<\/strong>, and yes, it does. That\u2019s how the number of likes<\/em> gets updated automatically.<\/p>\n
    Each AJAX call will be delayed by the average time of 1 second<\/strong> because the delay in triggering each call is 1 second from the server. The AJAX request will remain incomplete for that 1 second.<\/p>\n
    So there you go \u2013 a method of delaying an AJAX response from the server to get the number of Facebook likes<\/em>. Drop questions in our comment section if you have any doubts or thoughts. Thanks!<\/p>","protected":false},"excerpt":{"rendered":"
