System info

• Playwright Version: 1.49.1
• Operating System: All
• Browser: Chrome

Source code

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

(async () => {
  const browser = await chromium.launch({
    headless: false,
    viewport: null,
    channel: 'chrome',
  });
  const context = await browser.newContext();
  const page = await context.newPage();
  await page.routeWebSocket(() => true, ws => {
    const server = ws.connectToServer();
    ws.onMessage(message => {
      console.log('sent',message);
      server.send(message);
    });
    server.onMessage(message => {
      console.log('received',message);
      ws.send(message);
    });
