Engine NODE - Parsing html to get data with js

Hallo semuanya,

Sudah lama sekali codedoct tidak memberikan tutorial membuat suatu engine. Tutorial kali ini akan membahas tentang membuat sebuah engine parsing halaman html untuk menadapatkan data-datanya.

Engine ini akan dibuat menggunakan node.js, pada os windows.

Oke langsung saja kita buat enginenya,

Pertama, buat terlebih dahulu folder projectnya dan buat file js baru <nama_file>.js dalam hal ini codedoct memberi nama file test.js sehingga hasilnya akan tampak seperti ini,

Selanjutnya, install beberapa modul js yang diperlukan diantaranya,
request : for request url

cheerio : for parsing html

sleep : for delay execution code

Kemudian isikan code berikut pada file test.js yang sudah kita buat,

function w10e01l10c01o10me01()
{
 for (var i = 10000; i >= 0; i--) {
  console.log('.....................................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('............w........................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('..............e......................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('................l....................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('..................c..................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('....................o................');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('......................m..............');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('........................e............');
 };
 for (var i = 10000; i >= 0; i--) {
  console.log('.....................................');
 };
 console.log('--------------Dont Close-------------');
}

function p10r01o10c01e10s01s10i01n10g01()
{
 var sleep = require('sleep');
 console.log('Process...');
 sleep.sleep(5);
}

function g10e01t10N01a10m01e10()
{
 var os = require("os");
 var sleep = require('sleep');
 console.log('Hello: '+os.hostname());
 sleep.sleep(3);
}

function g1e0t1C0a1t0e1g0o1r0y1()
{
 var cheerio = require('cheerio');
 var request = require('request');
 var categoryArray = new Array();

 request({
     method: 'GET',
     url: 'http://m.bnizona.com/index.php/category/index/promo'
 }, function(err, response, body) {
     if (err) return console.log('This engine need connection..');
  //cherio
  $ = cheerio.load(body);
  $('ul.menu li a').each(function(i, element) {
      var category = $(this).text();
      var url_category = $(this).attr('href');

   categoryArray[category] = {};

   request({
    method: 'GET',
    url: url_category
   }, function(err, response, body) {
    if (err) return console.error(err);
    var j = 0;
    //cherio
    $ = cheerio.load(body);
    $('ul#lists li a').each(function(i, element) {
     var detail = $(this).find('span.promo-title').text();
     var image_url = $(this).find('img').attr('src');
     var title = $(this).find('span.merchant-name').text();
     var valid = $(this).find('span.valid-until').text();

     categoryArray[category][j] = {
      title : title,
      image_url : image_url,
      date_validation : valid,
      detail : detail,
     };
     j=j+1;
    });
    console.log(categoryArray);
   });
   // console.log(categoryArray);
  });
  // console.log(categoryArray);
 });
}

function s1t0o10p1P0r1o0c1e0s1s0()
{
 var sleep = require('sleep');
 console.log("Sorry i can't give you all the code");
 sleep.sleep(3);
 console.log("-------------------------------------");
 sleep.sleep(3);
}

function g1e0t1S0c1r0a1p0e1C0e1r0m1a0t1i0()
{
 w10e01l10c01o10me01();
 p10r01o10c01e10s01s10i01n10g01();
 g10e01t10N01a10m01e10();
 g1e0t1C0a1t0e1g0o1r0y1();
 s1t0o10p1P0r1o0c1e0s1s0();
}

g1e0t1S0c1r0a1p0e1C0e1r0m1a0t1i0();

Sehingga saat kita mnjalankan "node test.js" maka akan tampil data seperti ini,
