Krik

Installation

npm install --save krikjs

Initialization

const Krik = require('krikjs');
const Permintaan = new Krik.Permintaan();
const Scrapper = new Krik.Scrapper();

Permintaan / Request

The function Permintaan.getSource has following parameters:

• First parameter is the request_option, you can read about it at http://npmjs.com/package/request, this params is just extension from there. So, all the thing will be the same.

• Second params is is_generated_by_server. If true, we will use request package to make a request and get the webpage source. If false, we will use phantomJS to request the webpage with GET method.

Request a webpage and get a source

const Krik = require('krikjs');
const Permintaan = new Krik.Permintaan();
var request_option = {url: "https://docs.angularjs.org/tutorial/step_01"};

var css_selector = {
	title: 'title', 
	tutorial: '#wrapper > section > div > div.grid-right > div.ng-scope'
};

Permintaan.getSource(request_option, false).then(function (content) {
	console.log(content); // here is the source of the web page

});

DOM Selector

You can use jQuery DOM selector with package jsdom and jquery, for example if you want get all links in specific area from the webpage source:

const Krik = require('krikjs');
const Permintaan = new Krik.Permintaan();

var request_option = {url: "http://indeks.kompas.com/indeks/index/news"};
Permintaan.getSource(request_option, true).then(function (source) {

	var jsdom = require('jsdom');
	jsdom.env({
		html: source,
		done: function (err, window) {
			var $ = require("jquery")(window);

			var allLinks = $('#berita > div.kcm-main-list a').map( function() {
			    return $(this).attr('href');
			}).get();

			console.log(allLinks);

			grabNews(allLinks);
		}
	});

});

Scrapper

If you want to parse a webpage with easy method, you can just call Scrapper. For example, in the previous code we have get all links from Kompas.com, then we can open it one by one with following code:

const Krik = require('krikjs');
const Permintaan = new Krik.Permintaan();
const Scrapper = new Krik.Scrapper();

function grabNews(links) {
	for(let i=0; i<links.length; i++) {
		// foreach links, open it!
		Permintaan.getSource(links[i], true).then(function (content) {
			// then parse it!
			css_selector = 
			{
				title: '#leftside > div.kcm-read > div.kcm-read-top.clearfix > h2',
				content: '#leftside > div.kcm-read > div.kcm-read-body.clearfix > div.span6 > div > div.kcm-read-text',
				category: '#leftside > div.kcm-read > div.kcm-read-top.clearfix > ul > li:nth-child(2) > h4 > a',
				date: '#leftside > div.kcm-read > div.kcm-read-top.clearfix > div > div.kcm-date.msmall.grey'
			};

			Scrapper.parse(content, css_selector, true).then(function (parsed) {
				console.log(parsed);
			});

		});
	}
}
