API Reference

Classes

Class	Description
Accessibility	The Accessibility class provides methods for inspecting the browser'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 browser 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.
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 gather information about parts of JavaScript and CSS that were used by the page.
CSSCoverage
CustomError
DeviceRequestPrompt	Device request prompts let you respond to the page requesting for a device through an API like WebBluetooth.
DeviceRequestPromptDevice	Device in a request prompt.
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.
FileChooser	File 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.
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 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.
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 the browser. :::note One Browser instance might have multiple Page instances. :::
ProductLauncher	Describes a launcher - a class that is able to create and launch a browser instance.
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	Target represents a CDP target. In CDP a target is something that can be debugged such a frame, a page or a worker.
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	This class represents a WebWorker.
