What is Node-Unblocker?
Node-Unblocker is a Node.js module that helps to block Cross-Site Scripting (XSS) and other exploits in web scraping projects. This comprehensive tutorial will show you how to use Node Unblocker with your favorite web scraping tool, as well as some tips and tricks for avoiding common vulnerabilities.
Node-Unblocker was created by Kyle Simpson, owner of Black Duck Software, a leading provider of security solutions for web developers. He says that the motivation behind the creation of Node-Unblocker was his own experience working on vulnerable web scraped projects. “I found myself constantly dealing with XSS and other vulnerabilities in my own projects,” he says, “and I wanted to find a way to fix them without having to learn tons of new code.”
Node-Unblocker is based on the popular library called requestmond. Requestmond’s creators describe it this way: “requestmond is an easy-to-use request handling library for Node.js that makes it dead simple to deal with AJAX requests from your Node applications.” In other words, Node-Unblocker uses what requestmond does already to help make your web scraping project safer.
To get started using Node-Unblocker, install it using npm:
npm install node-unblocker
Once installed, you can use it in your project by adding the following line inside of your module’s require() function:

var UnBlocker = require ( ‘node-unblocker’ ); // your API key var unblockingOptions = {}; // your scraping options unblockingOptions . apiKey = ‘YOUR_API_KEY’ ; unblockingOptions . scrapingOptions = { }; // the url of the target website unblockingOptions . targetUrl = ‘https://www.example.com’ ; // optional: if you want to use HTTPS instead of HTTP unblockingOptions . httpsOnly : true ; // start the blocking process UnBlocker . start (unblockingOptions);
Next, you need to create an instance of UnBlocker and pass in your configuration file and your scraping options. To do this, use the UnBlocker class as follows:
var blocker = new UnBlocker (configFile, scrapingOptions);

How to remove blocking nodes from a web scraping project?
If you are trying to scrape a website and you find that certain nodes are blocking your scraping process, there is usually a way to remove the blocking nodes. This tutorial will walk you through the most common methods of removing blocking nodes from a web scraping project.
Blocking nodes can be caused by many things, including security measures implemented by websites, browser add-ons, and other tools used in web scraping. In some cases, blocking nodes may be due to improperly configured spiders or scrapers. In other cases, they may be due to mistakes made while crawling the website.
Most often, blocking nodes will simply cause the scraping process to fail prematurely. However, in some cases, removing the offending node may still allow the scraping process to complete successfully. Therefore, it is important to understand how blocking nodes can affect your project before attempting to remove them.
The first step in removing blocking nodes from a web scraping project is determining which ones are causing the problem. Often this can be done by reviewing the output of your spider or scraper as it runs on the website. This information includes information about which pages have been crawled and which pages have been blocked from being scraped.
If you are using an automated spider or scraper, then it is likely that all blocked pages will show up as missed pages in the output data stream. In this case, it may be easiest to simply disable the automated spider or scraper and manually inspect each page that was blocked from being
