}

Options for attaching to a running browser over CDP.

Fields

engine: EngineType

Browser automation engine used for the connection.

cdp_endpoint: Option<String>

HTTP DevTools endpoint, for example http://127.0.0.1:9222.

ws_endpoint: Option<String>

DevTools browser WebSocket endpoint.

slow_mo: u64

Slow down Playwright/Puppeteer operations by this many milliseconds.

timeout: Option<Duration>

Optional connection timeout.

protocol_timeout: Option<Duration>

Optional Puppeteer timeout for individual CDP calls.

seed_cookies: Vec<Value>

Cookies to seed after attaching, in CDP/Playwright cookie format.

storage_state: Option<StorageStateInput>

Playwright-compatible cookies and origin-scoped localStorage to restore.

verbose: bool

Enable verbose bridge logging.

node_executable: Option<PathBuf>

Node.js executable for Playwright/Puppeteer bridge engines.

node_working_dir: Option<PathBuf>

Directory where Node resolves the Playwright/Puppeteer package.

downloads: DownloadSetting

Manage the attached browser’s downloads.

The same setting and the same manager as LaunchOptions, because a browser somebody else started downloads files the same way — including the ones a person clicks by hand. See downloads.
