Apisix Reverse Proxy

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.

To quickly scrape a large number of sites using Node.js, you can leverage asynchronous programming and utilize libraries like axios for making HTTP requests and cheerio for parsing HTML. Additionally, you may consider using the p-queue library to manage the concurrency and control the rate of requests. Here's a basic example to get you started

Install Required Packages:

npm install axios cheerio p-queue

Create a Scraper Script:

const axios = require('axios');
const cheerio = require('cheerio');
const PQueue = require('p-queue');

// List of sites to scrape
const sites = [
  'https://example1.com',
  'https://example2.com',
  // Add more URLs as needed
];

// Set the concurrency level (adjust as needed)
const concurrency = 5;

// Initialize a queue with concurrency control
const queue = new PQueue({ concurrency });

// Function to scrape a single site
async function scrapeSite(url) {
  try {
    const response = await axios.get(url);
    const $ = cheerio.load(response.data);

    // Use Cheerio to parse and extract data
    const title = $('title').text();
    console.log(`Scraped ${url} - Title: ${title}`);
  } catch (error) {
    console.error(`Error scraping ${url}: ${error.message}`);
  }
}

// Enqueue scraping tasks for each site
sites.forEach((site) => {
  queue.add(() => scrapeSite(site));
});

// Wait for all tasks to complete
queue.onIdle().then(() => {
  console.log('All scraping tasks completed.');
});

This example uses axios for making HTTP requests, cheerio for HTML parsing, and p-queue for controlling concurrency.

Run the Script:

node your_scraper_script.js

Adjust the sites array with the URLs you want to scrape.

This example uses a simple queue system to control the number of concurrent requests, preventing potential issues with rate limiting or overwhelming the target websites. However, be mindful of the websites' terms of service and robots.txt rules to avoid scraping restrictions.

HTTP proxies are used for surfing the Internet and working with social networks. However, when using this type of proxy, the user's IP address remains unprotected. At the same time, the connection speed remains high.
SOCKS proxy are designed to use programs and visit sites anonymously. Also this type of proxy allows bypassing the resources with proxy-server protection.
To sum up: SOCKS proxies are a more advanced development compared to HTTP. However, to use SOCKS, you must know how to configure your browser and use special utilities.

To connect a proxy for Instagram, you need to use third-party services. With their help, you can assign a separate proxy for each account, through which the profile will work. An example of a service is Instaplus. You can also use built-in proxies on the site.

Go to the site Register and confirm profile creation via email (may go into your spam folder). Add accounts from Instagram. Click on your username at the top right. Go to "Proxy Settings." Click on "Add new proxy". Specify your proxy details. Select the Instagram accounts you want to proxy.
