Connect Puppeteer or Playwright

Obscura speaks the Chrome DevTools Protocol over WebSocket. Puppeteer and Playwright connect to it like remote Chrome.

Start the server

obscura serve --port 9222

obscura listening on ws://127.0.0.1:9222

Puppeteer

npm install puppeteer-core

const puppeteer = require('puppeteer-core');

const browser = await puppeteer.connect({
  browserWSEndpoint: 'ws://127.0.0.1:9222',
});

const page = await browser.newPage();
await page.goto('https://example.com');
console.log(await page.title()); // "Example Domain"

await browser.disconnect();

Use puppeteer-core, not puppeteer. The puppeteer package bundles a Chrome download.

Playwright

npm install playwright

const { chromium } = require('playwright');

const browser = await chromium.connectOverCDP('ws://127.0.0.1:9222');
const context = browser.contexts()[0] || await browser.newContext();
const page = await context.newPage();

await page.goto('https://example.com');
console.log(await page.title());

await browser.close();

Use connectOverCDP, not connect. Playwright's connect speaks Playwright's own protocol, which obscura does not implement.

waitUntil

Default is domcontentloaded. For full subresource load:

await page.goto('https://example.com', { waitUntil: 'load' });

Value	Returns when
domcontentloaded	HTML parsed, scripts ran (default)
load	All subresources finished
networkidle2	≤2 network connections active for 500ms
networkidle0	0 network connections active for 500ms

Supported

• page.goto, page.reload, page.goBack, page.goForward
• page.evaluate, page.evaluateHandle

• page.cookies, page.setCookie, context.cookies
