Whats up everybody!

I was a away for a long time, deep projects and shit, but I am back and will continue doing some course and more freebies.

Anyway, here is a brief domain crawler + email extractor I did with Node.JS using roboto library which is cool and easy. So here I go, step by step:

1.- Create a dir.
2.- Go inside of it.
3.- You need to install roboto and htmlstrip-native with npm.
4.- Create a crawl.js file inside that folder you created.
5.- Paste the source code on it:

Then just run the command using node like:
node crawler.js domain.com

Thats it, it will create a domain.com.txt with all the emails.

Your console will look like this:

And emails grabbed like this:


Obviously change domain.com by any domain you want to crawl and get emails.

IRC was the best 10 years ago, now other softwares have eclipsed, but many savvy people keep using it for proper communication with special individuals. So, if you never heard or configured eggdrops, this is something similar.

So first you will need to install NodeJS, and I will consider that you already have it, then you should have NPM also installed, then just install the irc library:

npm install irc

Once you have that, you need to specify that you are using this module and then set the configure on connecting to know which channels the bot will join automatically, and then set up the port, which is not a regular port for IRC but you need to set something more stable for a bot.

So as you see, first we set up the server, then the nick, and then we open encapsulation to add the channels, the port and a mode where we can see what is going on on your console.

NOTE: You might get some errors when connecting, but try again and again. When you are able to connect, no matter if you sleep your localhost, it will continue connecting. Also this is for leaving it working on a VPS or shell so you have a always online bot.

But now that you have your bot online, what’s next? You need to know wtf is going on in the channels that you join or the PM you receive, and for that we have listeners.

Before getting into this I will explain the functions we have available so we can use them when we get events on the listeners:

So now that you know the commands to use on the Events, we now are listing the Listeners for this stuff:

 

Hey fellas, sorry for being absent for a long time, mainly it was lots of work on other projects.

In this post I am going to teach you how to screen scrape using NodeJS and JQuery (cheerio). Its relatively easy, here is the code:

 

Hell yeah, this also deserves the place along nightmareJS, even though this doesnt use Electron for simulating browser, but a headless parser native libxml C bindings that will do a great job.

To start, you have to make sure you have previously installed nodejs libraries along with npm and if you get an error for the libxmljs library, make sure that you install this:

And then it should be working properly if you create a file.js and run the example script.

Here you have a bunch of examples to copy and paste to test it. In order to explain it further please ask your questions or requirements for video tutorials. I might open a premium spot for it, so you better fucking invite me a cup of oil so I can continue my compromise with you.

Craiglist example:

This is the official repo for Osmosis: https://github.com/rchipka/node-osmosis

It works like this:
