How to use a proxy with Playwright

import random
from playwright.sync_api import sync_playwright, ProxySettings

# List of proxies to rotate through
proxy_pool: list[ProxySettings] = [
    {
        "server": "http://<PROXY_SERVER_IP>:<PROXY_PORT>",
        "username": "<PROXY_USERNAME>",
        "password": "<PROXY_PASSWORD>",
    },
    {
        "server": "http://<PROXY_SERVER_IP>:<PROXY_PORT>",
        "username": "<PROXY_USERNAME>",
        "password": "<PROXY_PASSWORD>",
    },
]

with sync_playwright() as p:
    browser = p.chromium.launch()
    for i in range(3):
        proxy_conf = random.choice(proxy_pool)
        context = browser.new_context(proxy=proxy_conf)
        page = context.new_page()
        # returns your current IP address in JSON format
        page.goto("https://httpbin.org/ip")
        print(f"Request {i+1} IP result:", page.text_content("body"))
        # Close context to reset proxy for next iteration
        context.close()
    browser.close()

The output for each request will show a different IP address originating from whichever proxy was chosen. For example, the console output might look like:
Request 1 IP result: { "origin": "123.45.67.89" }
Request 2 IP result: { "origin": "11.22.33.44" }
Request 3 IP result: { "origin": "98.76.54.32" }

import { chromium } from "playwright";

const proxyPool = [
  {
    server: "http://<PROXY_SERVER_IP>:<PROXY_PORT>",
    username: "<PROXY_USERNAME>",
    password: "<PROXY_PASSWORD>",
  },
  {
    server: "http://<PROXY_SERVER_IP>:<PROXY_PORT>",
    username: "<PROXY_USERNAME>",
    password: "<PROXY_PASSWORD>",
  },
];

(async () => {
  const browser = await chromium.launch();

  for (let i = 0; i < 3; i++) {
    const proxyConf = proxyPool[Math.floor(Math.random() * proxyPool.length)];
    const context = await browser.newContext({ proxy: proxyConf });
    const page = await context.newPage();
    await page.goto("https://httpbin.org/ip");
    const result = await page.textContent("body");
    console.log(`Request ${i + 1} IP result:`, result);
    await context.close();
  }

  await browser.close();
})();
