Playwright

Connect Playwright to Lightcone browser sessions via Chrome DevTools Protocol.

Connect Playwright to Lightcone’s cloud browsers via Chrome DevTools Protocol (CDP). This gives you the full Playwright API running on Lightcone’s stealth-enabled, scalable browser infrastructure.

Install

Section titled “Install”
Terminal window
pip install tzafon playwright
playwright install chromium
Terminal window
npm install @tzafon/lightcone playwright
npx playwright install chromium

Example

Section titled “Example”
from tzafon import Lightcone
from playwright.sync_api import sync_playwright


client = Lightcone()
session = client.computers.create(kind="browser")


# Get the CDP endpoint from the session
cdp_url = session.endpoints.get("cdp")


with sync_playwright() as p:
    # Connect Playwright to the remote browser
    browser = p.chromium.connect_over_cdp(cdp_url)
    page = browser.contexts[0].pages[0]


    # Use the full Playwright API
    page.goto("https://example.com")
    page.fill("input[name='search']", "hello world")
    page.click("button[type='submit']")


    # Wait for results
    page.wait_for_selector(".results")
    content = page.inner_text("body")
    print(content[:500])


    browser.close()


client.computers.delete(session.id)
import Lightcone from "@tzafon/lightcone";
import { chromium } from "playwright";


const client = new Lightcone();
const session = await client.computers.create({ kind: "browser" });


const cdpUrl = session.endpoints?.cdp;


const browser = await chromium.connectOverCDP(cdpUrl!);
const page = browser.contexts()[0].pages()[0];


await page.goto("https://example.com");
await page.fill("input[name='search']", "hello world");
await page.click("button[type='submit']");


await page.waitForSelector(".results");
const content = await page.innerText("body");
console.log(content.slice(0, 500));


await browser.close();
await client.computers.delete(session.id!);

Async Python

Section titled “Async Python”
from tzafon import AsyncLightcone
from playwright.async_api import async_playwright


client = AsyncLightcone()
session = await client.computers.create(kind="browser")
cdp_url = session.endpoints.get("cdp")


async with async_playwright() as p:
    browser = await p.chromium.connect_over_cdp(cdp_url)
    page = browser.contexts[0].pages[0]
    await page.goto("https://example.com")
    # ...
    await browser.close()


await client.computers.delete(session.id)

Why use Playwright with Lightcone?
