Using proxies in your Node.js applications is essential for web scraping, bot automation, and accessing geo-restricted content at scale. This guide will show you how to integrate Squid Proxies with **JavaScript/Node.js** using both **datacenter** (`IP:Port`) and **residential** (`host:port`, like `p102.squidproxies.com:8907`) proxies — no username/password required.
## **Squid Proxies format overview** | Proxy Type | Format | Auth Method | |--------------|-------------------------------|------------------| | Datacenter | `123.45.67.89:3128` | IP & User/Pass Authorization | | Residential | `p102.squidproxies.com:8907` | IP & User/Pass Authorization | 📍 You must authorize your current IP address from your **Squid Proxies Dashboard** before connecting. No username or password is required.
## **System prerequisites** Before starting: - Node.js v14 or higher installed - Install required packages: ```bash npm install axios puppeteer https-proxy-agent ``` - Ensure your IP is whitelisted in the SquidProxies dashboard - Chrome installed (for Puppeteer)
## **Using Axios with Squid Proxies (HTTP requests)** Axios is a lightweight HTTP client for making API calls. You can use proxies with the `httpAgent` and `httpsAgent` parameters. ### **Datacenter proxy example (`IP:Port`)** ```js const axios = require('axios'); const HttpsProxyAgent = require('https-proxy-agent'); const proxy = 'http://123.45.67.89:3128'; const agent = new HttpsProxyAgent(proxy); axios.get('https://httpbin.org/ip', { httpsAgent: agent, headers: { 'User-Agent': 'Mozilla/5.0', }, }) .then(res => console.log('Datacenter IP:', res.data)) .catch(err => console.error('Request failed:', err.message)); ``` ### **Residential proxy example (`host:port`)** ```js const axios = require('axios'); const HttpsProxyAgent = require('https-proxy-agent'); const proxy = 'http://p102.squidproxies.com:8907'; const agent = new HttpsProxyAgent(proxy); axios.get('https://httpbin.org/ip', { httpsAgent: agent, }) .then(res => console.log('Residential IP:', res.data)) .catch(err => console.error('Error:', err.message)); ```
## **Datacenter proxy rotation with retry & delay** ```js const axios = require('axios'); const HttpsProxyAgent = require('https-proxy-agent'); const proxyPool = [ 'http://123.45.67.1:3128', 'http://123.45.67.2:3128', 'http://123.45.67.3:3128', ]; async function fetchWithRetry(url, maxRetries = 3, delay = 3000) { for (const proxy of proxyPool) { const agent = new HttpsProxyAgent(proxy); for (let attempt = 1; attempt <= maxRetries; attempt++) { try { const res = await axios.get(url, { httpsAgent: agent, timeout: 8000, }); console.log(`Success via ${proxy}:`, res.data); return; } catch (err) { console.warn(`Proxy ${proxy} failed (attempt ${attempt}): ${err.message}`); await new Promise(resolve => setTimeout(resolve, delay)); } } console.warn(`Proxy ${proxy} removed from pool after ${maxRetries} failed attempts.`); } console.error('All proxies failed.'); } fetchWithRetry('https://httpbin.org/ip'); ```
## **Using Puppeteer with Squid Proxies** ```js const puppeteer = require('puppeteer'); (async () => { const browser = await puppeteer.launch({ headless: true, args: ['--proxy-server=http://123.45.67.89:3128'], }); const page = await browser.newPage(); await page.goto('https://httpbin.org/ip'); const content = await page.content(); console.log(content); await browser.close(); })(); ```
## **Native HTTPS module with Squid Proxies** ```js const https = require('https'); const HttpsProxyAgent = require('https-proxy-agent'); const proxy = 'http://p102.squidproxies.com:8907'; const agent = new HttpsProxyAgent(proxy); https.get('https://httpbin.org/ip', { agent }, res => { res.setEncoding('utf8'); res.on('data', chunk => console.log(chunk)); }); ```
## **Best practices for Node.js proxy integration** | Tip | Why it matters | |----------------------------------|------------------------------------------------| | Add delay between requests | Prevents bans, especially on aggressive sites | | Rotate headers/user agents | Emulate browser behavior | | Monitor status codes | Detect blocks like 403, 429, 503 | | Use residential proxies for login| Persistent sessions, less detection | | Use datacenter for public scraping | Faster and cheaper for general data tasks |
