API Reference

Classes

ClassDescription
AccessibilityThe Accessibility class provides methods for inspecting Chromium's accessibility tree. The accessibility tree is used by assistive technology such as screen readers or switches.
BrowserA Browser is created when Puppeteer connects to a Chromium instance, either through PuppeteerNode.launch() or Puppeteer.connect().
BrowserContextBrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method Browser.newPage creates a page in the default browser context.
BrowserFetcherBrowserFetcher can download and manage different versions of Chromium and Firefox.
CDPSessionThe CDPSession instances are used to talk raw Chrome Devtools Protocol.
Connection
ConsoleMessageConsoleMessage objects are dispatched by page via the 'console' event.
CoverageThe Coverage class provides methods to gather information about parts of JavaScript and CSS that were used by the page.
CSSCoverage
CustomError
DeviceRequestPromptDevice request prompts let you respond to the page requesting for a device through an API like WebBluetooth.
DeviceRequestPromptDeviceDevice in a request prompt.
DialogDialog instances are dispatched by the Page via the dialog event.
ElementHandleElementHandle represents an in-page DOM element.
EventEmitterThe EventEmitter class that many Puppeteer classes extend.
FileChooserFile choosers let you react to the page requesting for a file.
Frame

Represents a DOM frame.

To understand frames, you can think of frames as <iframe> elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not effect frames inside the ambient frame the JavaScript executes in.

HTTPRequestRepresents an HTTP request sent by a page.
HTTPResponseThe HTTPResponse class represents responses which are received by the Page class.
JSCoverage
JSHandle

Represents a reference to a JavaScript object. Instances can be created using Page.evaluateHandle().

Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely disposed. JSHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.

Handles can be used as arguments for any evaluation function such as Page.$eval(), Page.evaluate(), and Page.evaluateHandle(). They are resolved to their referenced object.

KeyboardKeyboard provides an api for managing a virtual keyboard. The high level api is Keyboard.type(), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.
MouseThe Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.
Page

Page provides methods to interact with a single tab or extension background page in Chromium.

:::note

One Browser instance might have multiple Page instances.

:::

ProductLauncherDescribes a launcher - a class that is able to create and launch a browser instance.
ProtocolErrorProtocolError is emitted whenever there is an error from the protocol.
Puppeteer

The main Puppeteer class.

IMPORTANT: if you are using Puppeteer in a Node environment, you will get an instance of PuppeteerNode when you import or require puppeteer. That class extends Puppeteer, so has all the methods documented below as well as all that are defined on PuppeteerNode.

PuppeteerNode

Extends the main Puppeteer class with Node specific behaviour for fetching and downloading browsers.

If you're using Puppeteer in a Node environment, this is the class you'll get when you run require('puppeteer') (or the equivalent ES import).

SecurityDetailsThe SecurityDetails class represents the security details of a response that was received over a secure connection.
TargetTarget represents a CDP target. In CDP a target is something that can be debugged such a frame, a page or a worker.
TimeoutErrorTimeoutError is emitted whenever certain operations are terminated due to timeout.
TouchscreenThe Touchscreen class exposes touchscreen events.
TracingThe Tracing class exposes the tracing audit interface.
WebWorkerThis class represents a WebWorker.
