Proxy Rotator

Introduction

ProxyRotator is a JavaScript class that provides a mechanism for managing a pool of proxies and rotating them based on their availability and status.

Installation

npm install proxy-rotator-js

Usage

import ProxyRotator from 'proxy-rotator-js'

let proxies = ['proxy1', 'proxy2', 'proxy3']

let rotator = new ProxyRotator(proxies, options={})

console.log( rotator.next() ) // 'proxy1'
console.log( rotator.next() ) // 'proxy2'

or you can pass the path to a proxy file

import ProxyRotator from 'proxy-rotator-js'

let filename = '/path/to/proxy/file.txt'

let rotator = new ProxyRotator(filename, options={});


console.log( rotator.next() ) // 'proxy1'
console.log( rotator.next() ) // 'proxy2'

Initializes a new instance of ProxyRotator with the given proxies and options. The proxies parameter can be a file path or an array of proxies. The options parameter allows customization of various settings such as revive timer, shuffling, protocol assumption, and more. Methods

Methods

next() // Rotates the proxy by moving the front proxy to the end of the pool and returns it.

add(proxies) // Adds one or more proxies to the pool.

getAlive() //  Retrieves a random alive proxy from the pool.

setAlive(proxy) // Sets a specific proxy to an alive state.

setDead(proxy) // Sets a specific proxy to a dead state and moves it to the graveyard.

resurrect(proxy) // Moves a proxy from the graveyard back to the pool.

getPool() // Returns an array of proxies in the pool.

getPoolSize() // Returns the number of proxies in the pool.

getGraveyard() // Returns an array of proxies in the graveyard (dead proxies).

getGraveyardSize() // Returns the number of proxies in the graveyard.

remove(proxy) // Removes one or more proxies from the pool.

Properties

pool: Represents the pool of proxies as a queue.

graveyard: Stores proxies that are currently dead or inactive.

Options

const proxies = ['proxy1.example.com', 'proxy2.example.com'];
const options = {
    returnAs: 'object',
    revive_timer: 1000 * 60 * 30,
    shuffle: true,
    protocol: 'http',
    assume_aliveness: true,
    check_on_next: true
};

const proxyRotator = new ProxyRotator(proxies, options);

The following options can be passed to customize the behavior of the ProxyRotator:

- returnAs: Specifies the return type of proxies. Can be either 'string' or 'object'. Default: 'string'.
- revive_timer: Specifies the duration in milliseconds before a dead proxy is revived. Default: 1000 * 60 * 30 (30 minutes).
- protocol: Specifies a protocol for all proxies. Default: null.
- shuffle: Specifies whether to shuffle the proxies before adding them to the queue. Default: false.
- assume_aliveness: Specifies whether to assume all proxies are alive when first added instead of 'new'. Default: false.
- check_on_next: Specifies whether to check if proxies are alive when they are added to the queue. Default: false.

Testing your Proxies

import ProxyRotator from 'proxy-rotator-js'

let proxies = ['proxy1', 'proxy2', 'proxy3']

let rotator = new ProxyRotator(proxies, options={})

rotator.test()

Getting Started

To use the ProxyRotator class in your JavaScript project, follow these steps:

Make sure you have Node.js  and npm installed on your system.

npm install proxy-rotator-js

Import the ProxyRotator class into your JavaScript file using the following line of code:

Create an instance of ProxyRotator by calling the constructor and providing the required parameters. For example:

const proxies = ['proxy1:8000', 'proxy2:322', 'proxy3:543'];
const rotator = new ProxyRotator(proxies);

Access the properties and methods of the ProxyRotator object using dot notation. For example:

rotator.next();
// 'proxy1:500'
const poolSize = proxyRotator.getPoolSize();
// 3
const aliveProxy = proxyRotator.getAlive();
// 'proxy2:500'
proxyRotator.setAlive( 'proxy2:500' );
// null

Examples

import ProxyRotator from './ProxyRotator.js';

// Create an instance of ProxyRotator
const proxies = ['proxy1', 'proxy2', 'proxy3'];
const options = { revive_timer: 1800000, shuffle: true };
const proxyRotator = new ProxyRotator(proxies, options);

// Access the properties
console.log(proxyRotator.getGraveyard());  // Output: []
console.log(proxyRotator.getGraveyardSize());  // Output: 0
console.log(proxyRotator.getPool());  // Output: ['proxy1', 'proxy2', 'proxy3']
console.log(proxyRotator.getPoolSize());  // Output: 3

// Call the methods
proxyRotator.add('proxy4');
console.log(proxyRotator.getPool());  // Output: ['proxy1', 'proxy2', 'proxy3', 'proxy4']
proxyRotator.remove('proxy2');
console.log(proxyRotator.getPool());  // Output: ['proxy1', 'proxy3', 'proxy4']
const aliveProxy = proxyRotator.getAlive();
console.log(aliveProxy);  // Output: 'proxy1'
proxyRotator.setAlive('proxy3');
proxyRotator.next(); // prox1
proxyRotator.next(); // prox3
proxyRotator.next(); // prox4
console.log(proxyRotator.getPool());  // Output: ['proxy1', 'proxy4', 'proxy3']
