Node Pastebin Scraper

Setup

Install

Install dependencies

npm i node-pastebin-scraper

Build

Build the files, the output will be in the folder dist. You can import dist/index.js for non ES6 class compatible enviroments.

npm run build

Use example.js

You need nodemon for this.

npm i -g nodemon

Run the example as in example.js

npm run example

Usage: Basic

You can define an array of regex expressions to be matched to each paste's body, the scraper will run through the most recent posted 'pastes' on PasteBin once.

import PasteBinScraper from './src/index';

//wait 5 seconds before scanning the next paste (default time - recommended).
const scraper = new PasteBinScraper({ eachPasteWait: 5000 });


const expressions = [/password/i, / dump /i, /hotmail/i, /gmail/i, /yahoo/i, /hack/i, /leak/i, /db_pass/i, /db_password/i, /href/i, /class/i];

scraper.setExpressionsToMatch(expressions);

scraper.scrape()
    .then(()=>console.log('Finished Scraping recent pastes!'))
    .catch((e)=>console.error(e));

scraper.on('match',(paste)=>{
    console.log(`Matched paste! URL (${paste.url} , posted: ${paste.timePosted}`)
})

Usage: Poll Recent Pastes Continously

scraper.Repeat() exposes (https://www.npmjs.com/package/repeat) a Repeat object, which will scrape PasteBin as per it's configuration.

Note: Repeat is not being maintained anymore, so not recommended for Production use cases.

import PasteBinScraper from './src/index';

const scraper = new PasteBinScraper();


const expressions = [/password/i, / dump /i, /hotmail/i, /gmail/i, /yahoo/i, /hack/i, /leak/i, /db_pass/i, /db_password/i, /href/i, /class/i];

scraper.setExpressionsToMatch(expressions);

// under 3 minutes not recommended
scraper.Repeat().every(3, 'minutes').for(120, 'minutes');

scraper.on('match',(paste)=>{
    console.log(`Matched paste! URL (${paste.url} , posted: ${paste.timePosted}`)
})

API

constructor(ConfigurationObject)

ConfigurationObject.eachPasteWait

The only available configuration at this time is how long to wait before scanning the next paste.

const scraper = new PasteBinScraper({ eachPasteWait: 5000 });

scrape()

Starts scraping process, that is, look at Pastebin's recent pastes and iterate through each of them then emit the event match when the match condition is met.

Returns a promise that is resolved when the list of recent pastes has been iterated.

scraper.scrape();

setMatchCondition(Function)

You can customize what condition should be met when iterating through each paste by supplying a handler, the object 'paste' is passed which contains the attributes: url, postedTime, body

By default the match condition is just iterates through a set of regex expressions (set by setExpressionsToMatch) to ensure at least there is one match, before emitting the 'match' event.

// This example replaces the match condition for all scraping purposes

// If any paste satisfies this condition, 'match' will be emitted.

const handler = (paste)=>{
    let { url, postedTime, body } = paste;
    return body.match(/database/i)
}
scraper.setMatchCondition(handler);

setExpressionsToMatch(Array)

Sets an array of Regular Expressions that will need to be matched with a paste's body, assuming setMatchCondition has not been called (i.e the default match condition has not been replaced).

scraper.setExpressionsToMatch([/(password|pass)/i,/dralejandro/i]);

Repeat()

Exposes (https://www.npmjs.com/package/repeat) a Repeat object, which will scrape PasteBin as per it's configuration.

scraper.Repeat().every(3, 'minutes').for(120, 'minutes');

on(EventString, Handler)

EventString: 'match'

This event is passed a paste object which contains the attributes: url, postedTime, body;

 scraper.on('match',(paste)=>{
     //do something
 })
