How Does A Node Unblocker Work? Benefits & Use Cases

Introduction To Using A Node Unblocker

Although the internet allows you to access content from any part of the world, you can be faced with error messages. These error responses could be due to institutional restrictions or geographical restrictions. Subsequently, this can be very frustrating because it is like standing in front of a door without access to it. 

The Node Unblocker acts like a digital key that unlocks doors so that you can have an unlimited browsing experience. Therefore, this guide will delve into everything you need to know about the Node Unblocker including how to configure it as well as other frequently asked questions.

Let’s dive in!

What is a Node Unblocker?

A Node Unblocker is an open-source web proxy service that routes your network traffic through its servers. Subsequently, it acts as an intermediary between your device and website you want to visit and this gives you access to blocked content.  

Unlike traditional proxy services, the Node Unblocker does not come with proxy servers. Hence, it cannot hide your device IP address when you visit a website. Therefore, you need to obtain a quality proxy from a reputable provider. Subsequently, this facilitates the communication between your device and the external proxies which plays a crucial role in automated activities like web scraping. 

This functionality is particularly beneficial in environments with stringent internet usage policies, such as educational institutions or workplaces, where access to certain websites may be restricted. By deploying a Node Unblocker, users can establish a local proxy server that redirects their network requests to external servers, effectively granting access to previously inaccessible content.

It’s important to note that while a Node Unblocker can mask activities from network administrators, it does not provide complete anonymity, as the original IP address remains visible to the target website. Therefore, for enhanced privacy and security, integrating a Node Unblocker with high-quality proxies from reputable providers, such as NetNut, is recommended.

The Node Unblocker works by establishing a local proxy server that reroutes user’s network requests to unrestricted external servers. Although it does not hide your IP address, it can mask your activities from your network administrator. 

How to Use Node Unblocker

Before you can use Node Unblocker, you need to set up some things. Subsequently, you may need to install some software on your device. Here is a step-by-step guide on how to use Node Unblocker:

Install Node.js

The first step is to install Node.js from the official website because Node Unblocker is written in JavaScript and is based on the Node.js runtime environment. Be sure to get the latest version as it contains upgrades that may be crucial to your activities. Once you have downloaded and installed it, follow the installation wizard and set it up on your device. 

You can verify that the package has been successfully installed by running this command in your terminal:

npm –v

Create a new Node.js project

Open the terminal and use the cd command to locate the directory you want to create a new Node project as shown below:

cd path/to/your/project

Subsequently, you need to initialize the project by running the following command:

npm init -y

The code above will create a new package.json file where you can define the project parameters. 

Install the necessary packages

This step involves installing two crucial packages- Express.js and Node Unblocker. Express.js is a web application framework for Node.js and it was designed to simplify the process of building web applications and APIs. Here is the code to install it:

npm i express unblocker

Once they are installed, you will see a new node_modules folder inside your project directory that contains the express and unblocker modules. 

Create the node Unblocker script

In the directory of your project, create a new index.js file and open it. Write the script by importing the required libraries like this:

var express = require(‘express’)

var Unblocker = require(‘unblocker’);

Next, create new express and unblocker instances. In addition, you can define the prefix you want to use in your URL for the new unblocker instance. You can name it anything you want, for example, “proxy”

var app = express();

var unblocker = new Unblocker({prefix: ‘/proxy/’});

Next, you can write a code that tells the Express application to use the middleware function unblocker to handle incoming HTTP requests:

app.use(unblocker);

You can define a route for handling HTTP GET requests to the root URL (‘/’).When you send a GET request, Express will execute the callback function provided as the second argument. Within the callback function, req represents the HTTP request object and res represents the HTTP response object. The function typically contains logic to process the incoming request and send an appropriate response. However, for this example we can set it at default:

app.get(‘/’, function(req, res) {

});

Here is what the full script should look like:

// Import required libraries

var express = require(‘express’)

var Unblocker = require(‘unblocker’);

// Create new express and unblocker instances. Set a prefix to use in the URL

var app = express();

var unblocker = new Unblocker({prefix: ‘/proxy/’});

// Tell the Express application to use the Unblocker middleware to handle HTTP requests

app.use(unblocker);

// Define a route to handle HTTP GET requests

app.get(‘/’, function(req, res) {

});

Run the Node Unblocker

At this stage, the script is ready for use. To run the script, you need to execute the command below in the terminal:

node index.js

Subsequently, a new instance of Node Unblocker will be started locally. Next, you can open any browser of your choice and enter the URL you are trying to access in this format:

  localhost:[port]/[prefix]/https://example.com/ 

What are some of the best practices for using Node Unblocker?

Here are some of the best practices when using Node Unblocker especially for web scraping:

One of the best practices for using Node Unblocker is to frequently monitor your scraping activities and adjust parameters as required. In addition, you should check for changes in the website structure or layout that could affect the Node Unblocker script. 

Rotate user-agent headers

For web scraping, it is crucial to rotate user-agent headers so that your request can look like it is coming from various users. In addition, rotating user agent headers reduces the chances of being identified as a bot by the website. 

Implement IP rotation

Using a single proxy IP is quite similar to accessing a website without a proxy because the chances of IP ban remain high. Therefore, you need to implement IP rotation to avoid getting detected and blocked. This ensures you have unlimited access to web data collection. 

Limit frequency of requests

Another best practice that must not be overlooked is rate limiting. Sending too many requests from an IP address within seconds can trigger anti-bot mechanisms on a website which can result in IP block. Therefore, implanting delay in your web scraping code helps you avoid these unpleasant situations. 

Error handling

Error handling is another crucial aspect that plays a significant role in web data extraction. Implement codes to handle potential errors you may experience when the target website is unable to return the desired response.
