Lightsabing Node/PhantomJS crawler. Crawl almost everything, including AJAX content.
JEDI CRAWLER is a Node/PhantomJS crawler made to scrape pretty much anything from Node, with a really simple syntax. Work in progress ladies
npm install jedi-crawler
Register padawans to the jedi crawler, that have a pattern to match a URL, and jQuery-style selectors. You can also post-process the data if you need to do some treatment (number conversion, etc)
For now only two types of selectors are supported : "text" and "src"
I find having one file per padawan (crawler) pretty cool for code clarity and also padawans need to learn by themselve and be alone
npm install jedi-crawlers
You can then give your padawans to the Jedi by doing
var jedi = ;jedi;
And then you can do
As the jedi will figure out what padawan to use given on the URL and of the pattern you set
Crawlers only start to scrape the page as soon as $(document).ready is fired. Our own version of jQuery is injected into the page, but then we also give back the $ to its owner in case they're executing 3rd party libraries to modify the DOM or w/e
If your selectors matches severals DOM elements, then an array of every value is returned
Right now, PhantomJS is instantiated with "--load-images=no" option so the page loads faster
Pull that bad boy Make sure you have PhantomJS installed Run node main.js
