CDPSession instances are used to talk raw Chrome Devtools Protocol. |
-| [Connection](./puppeteer.connection.md) | |
-| [ConsoleMessage](./puppeteer.consolemessage.md) | ConsoleMessage objects are dispatched by page via the 'console' event. |
-| [Coverage](./puppeteer.coverage.md) | The Coverage class provides methods to gathers information about parts of JavaScript and CSS that were used by the page. |
-| [CSSCoverage](./puppeteer.csscoverage.md) | |
-| [CustomError](./puppeteer.customerror.md) | |
-| [Dialog](./puppeteer.dialog.md) | Dialog instances are dispatched by the [Page](./puppeteer.page.md) via the dialog event. |
-| [ElementHandle](./puppeteer.elementhandle.md) | ElementHandle represents an in-page DOM element. |
-| [EventEmitter](./puppeteer.eventemitter.md) | The EventEmitter class that many Puppeteer classes extend. |
-| [ExecutionContext](./puppeteer.executioncontext.md) | Represents a context for JavaScript execution. |
-| [FileChooser](./puppeteer.filechooser.md) | File choosers let you react to the page requesting for a file. |
-| [Frame](./puppeteer.frame.md) | At every point of time, page exposes its current frame tree via the [page.mainFrame](./puppeteer.page.mainframe.md) and [frame.childFrames](./puppeteer.frame.childframes.md) methods. |
-| [HTTPRequest](./puppeteer.httprequest.md) | Represents an HTTP request sent by a page. |
-| [HTTPResponse](./puppeteer.httpresponse.md) | The HTTPResponse class represents responses which are received by the [Page](./puppeteer.page.md) class. |
-| [JSCoverage](./puppeteer.jscoverage.md) | |
-| [JSHandle](./puppeteer.jshandle.md) | Represents a reference to a JavaScript object. Instances can be created using [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md).
Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely [disposed](./puppeteer.jshandle.dispose.md). 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()](./puppeteer.page._eval.md), [Page.evaluate()](./puppeteer.page.evaluate.md), and [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md). They are resolved to their referenced object.
| -| [Keyboard](./puppeteer.keyboard.md) | Keyboard provides an api for managing a virtual keyboard. The high level api is [Keyboard.type()](./puppeteer.keyboard.type.md), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page. | -| [Mouse](./puppeteer.mouse.md) | The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport. | -| [Page](./puppeteer.page.md) |Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium.
:::note
One Browser instance might have multiple Page instances.
:::
| -| [ProtocolError](./puppeteer.protocolerror.md) | ProtocolError is emitted whenever there is an error from the protocol. | -| [Puppeteer](./puppeteer.puppeteer.md) |The main Puppeteer class.
IMPORTANT: if you are using Puppeteer in a Node environment, you will get an instance of [PuppeteerNode](./puppeteer.puppeteernode.md) 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](./puppeteer.puppeteernode.md).
Extends the main [Puppeteer](./puppeteer.puppeteer.md) 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).

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.

Evaluates the given function.
Unlike [evaluate](./puppeteer.executioncontext.evaluate.md), this method returns a handle to the result of the function.
This method may be better suited if the object cannot be serialized (e.g. Map) and requires further manipulation.
