<tbody><tr><td>

<span id="accessibility">[Accessibility](./puppeteer.accessibility.md)</span>

</td><td>

The Accessibility class provides methods for inspecting the browser's accessibility tree. The accessibility tree is used by assistive technology such as [screen readers](https://en.wikipedia.org/wiki/Screen_reader) or [switches](https://en.wikipedia.org/wiki/Switch_access).

**Remarks:**

Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might have wildly different output.

Blink - Chrome's rendering engine - has a concept of "accessibility tree", which is then translated into different platform-specific APIs. Accessibility namespace gives users access to the Blink Accessibility Tree.

Most of the accessibility tree gets filtered out when converting from Blink AX Tree to Platform-specific AX-Tree or by assistive technologies themselves. By default, Puppeteer tries to approximate this filtering, exposing only the "interesting" nodes of the tree.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Accessibility` class.

</td></tr>
<tr><td>

<span id="browser">[Browser](./puppeteer.browser.md)</span>

</td><td>

[Browser](./puppeteer.browser.md) represents a browser instance that is either:

- connected to via [Puppeteer.connect()](./puppeteer.puppeteer.connect.md) or - launched by [PuppeteerNode.launch()](./puppeteer.puppeteernode.launch.md).

[Browser](./puppeteer.browser.md) [emits](./puppeteer.eventemitter.emit.md) various events which are documented in the [BrowserEvent](./puppeteer.browserevent.md) enum.

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Browser` class.

</td></tr>
<tr><td>

<span id="browsercontext">[BrowserContext](./puppeteer.browsercontext.md)</span>

</td><td>

[BrowserContext](./puppeteer.browsercontext.md) represents individual user contexts within a [browser](./puppeteer.browser.md).

When a [browser](./puppeteer.browser.md) is launched, it has a single [browser context](./puppeteer.browsercontext.md) by default. Others can be created using [Browser.createBrowserContext()](./puppeteer.browser.createbrowsercontext.md). Each context has isolated storage (cookies/localStorage/etc.)

[BrowserContext](./puppeteer.browsercontext.md) [emits](./puppeteer.eventemitter.md) various events which are documented in the [BrowserContextEvent](./puppeteer.browsercontextevent.md) enum.

If a [page](./puppeteer.page.md) opens another [page](./puppeteer.page.md), e.g. using `window.open`, the popup will belong to the parent [page's browser context](./puppeteer.page.browsercontext.md).

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `BrowserContext` class.

</td></tr>
<tr><td>

<span id="cdpsession">[CDPSession](./puppeteer.cdpsession.md)</span>

</td><td>

The `CDPSession` instances are used to talk raw Chrome Devtools Protocol.

**Remarks:**

Protocol methods can be called with [CDPSession.send()](./puppeteer.cdpsession.send.md) method and protocol events can be subscribed to with `CDPSession.on` method.

Useful links: [DevTools Protocol Viewer](https://chromedevtools.github.io/devtools-protocol/) and [Getting Started with DevTools Protocol](https://github.com/aslushnikov/getting-started-with-cdp/blob/HEAD/README.md).

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `CDPSession` class.

</td></tr>
<tr><td>

<span id="connection">[Connection](./puppeteer.connection.md)</span>

</td><td>

</td></tr>
<tr><td>

<span id="consolemessage">[ConsoleMessage](./puppeteer.consolemessage.md)</span>

</td><td>

ConsoleMessage objects are dispatched by page via the 'console' event.

</td></tr>
<tr><td>

<span id="coverage">[Coverage](./puppeteer.coverage.md)</span>

</td><td>

The Coverage class provides methods to gather information about parts of JavaScript and CSS that were used by the page.

**Remarks:**

To output coverage in a form consumable by [Istanbul](https://github.com/istanbuljs), see [puppeteer-to-istanbul](https://github.com/istanbuljs/puppeteer-to-istanbul).

</td></tr>
<tr><td>

<span id="csscoverage">[CSSCoverage](./puppeteer.csscoverage.md)</span>

</td><td>

</td></tr>
<tr><td>

<span id="devicerequestprompt">[DeviceRequestPrompt](./puppeteer.devicerequestprompt.md)</span>

</td><td>

Device request prompts let you respond to the page requesting for a device through an API like WebBluetooth.

**Remarks:**

`DeviceRequestPrompt` instances are returned via the [Page.waitForDevicePrompt()](./puppeteer.page.waitfordeviceprompt.md) method.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `DeviceRequestPrompt` class.

</td></tr>
<tr><td>

<span id="devicerequestpromptdevice">[DeviceRequestPromptDevice](./puppeteer.devicerequestpromptdevice.md)</span>

</td><td>

Device in a request prompt.

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `DeviceRequestPromptDevice` class.

</td></tr>
<tr><td>

<span id="dialog">[Dialog](./puppeteer.dialog.md)</span>

</td><td>

Dialog instances are dispatched by the [Page](./puppeteer.page.md) via the `dialog` event.

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Dialog` class.

</td></tr>
<tr><td>

<span id="elementhandle">[ElementHandle](./puppeteer.elementhandle.md)</span>

</td><td>

ElementHandle represents an in-page DOM element.

**Remarks:**

ElementHandles can be created with the [Page.$()](./puppeteer.page._.md) method.

```ts
import puppeteer from 'puppeteer';

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  const hrefElement = await page.$('a');
  await hrefElement.click();
  // ...
})();
```

ElementHandle prevents the DOM element from being garbage-collected unless the handle is [disposed](./puppeteer.jshandle.dispose.md). ElementHandles are auto-disposed when their origin frame gets navigated.

ElementHandle instances can be used as arguments in [Page.$eval()](./puppeteer.page._eval.md) and [Page.evaluate()](./puppeteer.page.evaluate.md) methods.

If you're using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a `<select>` element, you can type it as `ElementHandle<HTMLSelectElement>` and you get some nicer type checks.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ElementHandle` class.

</td></tr>
<tr><td>

<span id="eventemitter">[EventEmitter](./puppeteer.eventemitter.md)</span>

</td><td>

The EventEmitter class that many Puppeteer classes extend.

**Remarks:**

This allows you to listen to events that Puppeteer classes fire and act accordingly. Therefore you'll mostly use [on](./puppeteer.eventemitter.on.md) and [off](./puppeteer.eventemitter.off.md) to bind and unbind to event listeners.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `EventEmitter` class.

</td></tr>
<tr><td>

<span id="filechooser">[FileChooser](./puppeteer.filechooser.md)</span>

</td><td>

File choosers let you react to the page requesting for a file.

**Remarks:**

`FileChooser` instances are returned via the [Page.waitForFileChooser()](./puppeteer.page.waitforfilechooser.md) method.

In browsers, only one file chooser can be opened at a time. All file choosers must be accepted or canceled. Not doing so will prevent subsequent file choosers from appearing.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `FileChooser` class.

</td></tr>
<tr><td>

<span id="frame">[Frame](./puppeteer.frame.md)</span>

</td><td>

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.

**Remarks:**

Frame lifecycles are controlled by three events that are all dispatched on the parent [page](./puppeteer.frame.page.md):

- [PageEvent.FrameAttached](./puppeteer.pageevent.md) - [PageEvent.FrameNavigated](./puppeteer.pageevent.md) - [PageEvent.FrameDetached](./puppeteer.pageevent.md)

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Frame` class.

</td></tr>
<tr><td>

<span id="httprequest">[HTTPRequest](./puppeteer.httprequest.md)</span>

</td><td>

Represents an HTTP request sent by a page.

**Remarks:**

Whenever the page sends a request, such as for a network resource, the following events are emitted by Puppeteer's `page`:

- `request`: emitted when the request is issued by the page. - `requestfinished` - emitted when the response body is downloaded and the request is complete.

If request fails at some point, then instead of `requestfinished` event the `requestfailed` event is emitted.

All of these events provide an instance of `HTTPRequest` representing the request that occurred:

```
page.on('request', request => ...)
```

NOTE: HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with `requestfinished` event.

If request gets a 'redirect' response, the request is successfully finished with the `requestfinished` event, and a new request is issued to a redirected url.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `HTTPRequest` class.

</td></tr>
<tr><td>

<span id="httpresponse">[HTTPResponse](./puppeteer.httpresponse.md)</span>

</td><td>

The HTTPResponse class represents responses which are received by the [Page](./puppeteer.page.md) class.

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `HTTPResponse` class.

</td></tr>
<tr><td>

<span id="jscoverage">[JSCoverage](./puppeteer.jscoverage.md)</span>

</td><td>

</td></tr>
<tr><td>

<span id="jshandle">[JSHandle](./puppeteer.jshandle.md)</span>

</td><td>

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.

**Remarks:**

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `JSHandle` class.

</td></tr>
<tr><td>

<span id="keyboard">[Keyboard](./puppeteer.keyboard.md)</span>

</td><td>

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.

**Remarks:**

For finer control, you can use [Keyboard.down()](./puppeteer.keyboard.down.md), [Keyboard.up()](./puppeteer.keyboard.up.md), and [Keyboard.sendCharacter()](./puppeteer.keyboard.sendcharacter.md) to manually fire events as if they were generated from a real keyboard.

On macOS, keyboard shortcuts like `⌘ A` -&gt; Select All do not work. See [\#1313](https://github.com/puppeteer/puppeteer/issues/1313).

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Keyboard` class.

</td></tr>
<tr><td>

<span id="locator">[Locator](./puppeteer.locator.md)</span>

</td><td>

</td></tr>
<tr><td>

<span id="mouse">[Mouse](./puppeteer.mouse.md)</span>

</td><td>

The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.

**Remarks:**

Every `page` object has its own Mouse, accessible with \[`page.mouse`\](\#pagemouse).

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Mouse` class.

</td></tr>
<tr><td>

<span id="page">[Page](./puppeteer.page.md)</span>

</td><td>
