Overview

  • extends: [EventEmitter]

A Browser is created via [`method: BrowserType.launch`]. An example of using a `Browser` to create a `Page`:

“`python sync from playwright.sync_api import sync_playwright

def run(playwright):

firefox = playwright.firefox
browser = firefox.launch()
page = browser.new_page()
page.goto("https://example.com")
browser.close()

with sync_playwright() as playwright:

run(playwright)

“`

Constructor Details

This class inherits a constructor from Playwright::PlaywrightApi

Instance Method Details

#close ⇒ Object

In case this browser is obtained using [`method: BrowserType.launch`], closes the browser and all of its pages (if any were opened).

In case this browser is connected to, clears all created contexts belonging to this browser and disconnects from the browser server.

The `Browser` object itself is considered to be disposed and cannot be used anymore.

def close
  wrap_impl(@impl.close)
end

#connected? ⇒ Boolean

Indicates that the browser is connected.

Returns:

  • (Boolean)

def connected?
  wrap_impl(@impl.connected?)
end

#contexts ⇒ Object

Returns an array of all open browser contexts. In a newly created browser, this will return zero browser contexts.

“`python sync browser = pw.webkit.launch() print(len(browser.contexts())) # prints `0` context = browser.new_context() print(len(browser.contexts())) # prints `1` “`

end

#new_browser_cdp_session ⇒ Object

> NOTE: CDP Sessions are only supported on Chromium-based browsers.

Returns the newly created browser session.

Creates a new browser context. It won't share cookies/cache with other browser contexts.

“`python sync browser = playwright.firefox.launch() # or “chromium” or “webkit”. # create a new incognito browser context. context = browser.new_context() # create a new page in a pristine context. page = context.new_page() page.goto(“example.com”) “`

Creates a new page in a new browser context. Closing this page will close the context as well.

This is a convenience API that should only be used for the single-page scenarios and short snippets. Production code and testing frameworks should explicitly create [`method: Browser.newContext`] followed by the

`method: BrowserContext.newPage`

to control their exact life times.

#start_tracing(page: nil, categories: nil, path: nil, screenshots: nil) ⇒ Object

> NOTE: This API controls [Chromium Tracing](www.chromium.org/developers/how-tos/trace-event-profiling-tool) which is a low-level chromium-specific debugging tool. API to control [Playwright Tracing](../trace-viewer) could be found [here](./class-tracing).

You can use [`method: Browser.startTracing`] and [`method: Browser.stopTracing`] to create a trace file that can be opened in Chrome DevTools performance panel.

“`python sync browser.start_tracing(page, path=“trace.json”) page.goto(“www.google.com”) browser.stop_tracing() “`
