API Reference

Classes

Class	Description
Accessibility	The Accessibility class provides methods for inspecting Chromium's accessibility tree. The accessibility tree is used by assistive technology such as screen readers or switches.
Browser	A Browser is created when Puppeteer connects to a Chromium instance, either through PuppeteerNode.launch() or Puppeteer.connect().
BrowserContext	BrowserContexts 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.
BrowserFetcher	BrowserFetcher can download and manage different versions of Chromium and Firefox.
CDPSession	The CDPSession instances are used to talk raw Chrome Devtools Protocol.
Connection
ConsoleMessage	ConsoleMessage objects are dispatched by page via the 'console' event.
Coverage	The Coverage class provides methods to gathers information about parts of JavaScript and CSS that were used by the page.
CSSCoverage
CustomError
Dialog	Dialog instances are dispatched by the Page via the dialog event.
ElementHandle	ElementHandle represents an in-page DOM element.
EventEmitter	The EventEmitter class that many Puppeteer classes extend.
ExecutionContext	This class represents a context for JavaScript execution. A [Page] might have many execution contexts: - each frame has "default" execution context that is always created after frame is attached to DOM. This context is returned by the Frame.executionContext() method. - Extension's content scripts create additional execution contexts. Besides pages, execution contexts can be found in workers.
FileChooser	File choosers let you react to the page requesting for a file.
Frame	At every point of time, page exposes its current frame tree via the page.mainFrame and frame.childFrames methods.
HTTPRequest	Represents an HTTP request sent by a page.
HTTPResponse	The HTTPResponse class represents responses which are received by the Page class.
JSCoverage
JSHandle	Represents an in-page JavaScript object. JSHandles can be created with the page.evaluateHandle method.
Keyboard	Keyboard 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.
Mouse	The 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. :::
ProtocolError	ProtocolError 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).
SecurityDetails	The SecurityDetails class represents the security details of a response that was received over a secure connection.
Target
TimeoutError	TimeoutError is emitted whenever certain operations are terminated due to timeout.
Touchscreen	The Touchscreen class exposes touchscreen events.
Tracing	The Tracing class exposes the tracing audit interface.
WebWorker	The WebWorker class represents a WebWorker.
