Getting Started

📋 Prerequisites

• Windows
• Google Chrome
• Node.js 20+
• A workspace with playwright or playwright-core

🚀 Launch the dedicated browser

From the repository root:

powershell -ExecutionPolicy Bypass -File .\scripts\launch_logged_in_chrome.ps1

The launch step is only complete when both of these are true:

• a chrome.exe process is using the dedicated profile directory
• the CDP endpoint http://127.0.0.1:<port>/json/version is reachable

The default launch uses:

• D:\Prj\onizuka-playwright-profile
• port 9222
• https://accounts.google.com/

🔐 Log in manually

Use the newly opened Chrome window and complete Google login yourself.

🔎 Verify the CDP port

powershell -ExecutionPolicy Bypass -File .\scripts\check_cdp_port.ps1

If this check fails, stop and relaunch instead of attempting Playwright attach anyway.

🎭 Attach Playwright

var chromium;
var attachedBrowser;
var attachedContext;
var attachedPage;

{
  const nm = await import("node:module");
  const requireForPw = nm.createRequire("file:///D:/Prj/demo/package.json");
  ({ chromium } = requireForPw("playwright-core"));

  attachedBrowser = await chromium.connectOverCDP("http://127.0.0.1:9222");
  attachedContext = attachedBrowser.contexts()[0];
  attachedPage = attachedContext.pages()[0];
}
