# Page class
Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in the browser.
:::note
One Browser instance might have multiple Page instances.
:::
#### Signature:
```typescript
export declare abstract class Page extends EventEmitter<PageEvents>
```
**Extends:** [EventEmitter](./puppeteer.eventemitter.md)&lt;[PageEvents](./puppeteer.pageevents.md)&gt;
## 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 `Page` class.
## Example 1
This example creates a page, navigates it to a URL, and then saves a screenshot:
```ts
import puppeteer from 'puppeteer';
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
await page.screenshot({path: 'screenshot.png'});
await browser.close();
})();
```
The Page class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [PageEvent](./puppeteer.pageevent.md) enum.
## Example 2
This example logs a message for a single page `load` event:
```ts
page.once('load', () => console.log('Page loaded!'));
```
To unsubscribe from events use the [EventEmitter.off()](./puppeteer.eventemitter.off.md) method:
```ts
function logRequest(interceptedRequest) {
console.log('A request was made:', interceptedRequest.url());
}
page.on('request', logRequest);
// Sometime later...
page.off('request', logRequest);
```

<tbody><tr><td>
<span id="accessibility">accessibility</span>
</td><td>
`readonly`
</td><td>
[Accessibility](./puppeteer.accessibility.md)
</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.

[Coverage](./puppeteer.coverage.md)
</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).

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

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

<span id="tracing">tracing</span>
</td><td>
`readonly`
</td><td>
[Tracing](./puppeteer.tracing.md)
</td><td>
The Tracing class exposes the tracing audit interface.
**Remarks:**
You can use `tracing.start` and `tracing.stop` to create a trace file which can be opened in Chrome DevTools or [timeline viewer](https://chromedevtools.github.io/timeline-viewer/).
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Tracing` class.

</td></tr>
<tr><td>
<span id="click">[click(selector, options)](./puppeteer.page.click.md)</span>
</td><td>
</td><td>
This method fetches an element with `selector`, scrolls it into view if needed, and then uses [Page.mouse](./puppeteer.page.md#mouse) to click in the center of the element. If there's no element matching `selector`, the method throws an error.
**Remarks:**
Bear in mind that if `click()` triggers a navigation event and there's a separate `page.waitForNavigation()` promise to be resolved, you may end up with a race condition that yields unexpected results. The correct pattern for click and wait for navigation is the following:
```ts
const [response] = await Promise.all([
page.waitForNavigation(waitOptions),
page.click(selector, clickOptions),
]);
```

<tr><td>
<span id="createpdfstream">[createPDFStream(options)](./puppeteer.page.createpdfstream.md)</span>
</td><td>
</td><td>
Generates a PDF of the page with the `print` CSS media type.
**Remarks:**
To generate a PDF with the `screen` media type, call [\`page.emulateMediaType('screen')\`](./puppeteer.page.emulatemediatype.md) before calling `page.pdf()`.
By default, `page.pdf()` generates a pdf with modified colors for printing. Use the [\`-webkit-print-color-adjust\`](https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-print-color-adjust) property to force rendering of exact colors.

</td><td>
</td><td>
</td></tr>
<tr><td>
<span id="emulate">[emulate(device)](./puppeteer.page.emulate.md)</span>
</td><td>
</td><td>
Emulates a given device's metrics and user agent.
To aid emulation, Puppeteer provides a list of known devices that can be via [KnownDevices](./puppeteer.knowndevices.md).
**Remarks:**
This method is a shortcut for calling two methods: [Page.setUserAgent()](./puppeteer.page.setuseragent.md) and [Page.setViewport()](./puppeteer.page.setviewport.md).
This method will resize the page. A lot of websites don't expect phones to change size, so you should emulate before navigating to the page.

</td><td>
</td><td>
This does not affect WebSockets and WebRTC PeerConnections (see https://crbug.com/563644). To set the page offline, you can use [Page.setOfflineMode()](./puppeteer.page.setofflinemode.md).
A list of predefined network conditions can be used by importing [PredefinedNetworkConditions](./puppeteer.predefinednetworkconditions.md).

<tr><td>
<span id="evaluate">[evaluate(pageFunction, args)](./puppeteer.page.evaluate.md)</span>
</td><td>
</td><td>
Evaluates a function in the page's context and returns the result.
If the function passed to `page.evaluate` returns a Promise, the function will wait for the promise to resolve and return its value.
</td></tr>
<tr><td>
<span id="evaluatehandle">[evaluateHandle(pageFunction, args)](./puppeteer.page.evaluatehandle.md)</span>
</td><td>
</td><td>
**Remarks:**
The only difference between [page.evaluate](./puppeteer.page.evaluate.md) and `page.evaluateHandle` is that `evaluateHandle` will return the value wrapped in an in-page object.
If the function passed to `page.evaluateHandle` returns a Promise, the function will wait for the promise to resolve and return its value.
You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):
</td></tr>
<tr><td>
<span id="evaluateonnewdocument">[evaluateOnNewDocument(pageFunction, args)](./puppeteer.page.evaluateonnewdocument.md)</span>
</td><td>
</td><td>
Adds a function which would be invoked in one of the following scenarios:
- whenever the page is navigated
- whenever the child frame is attached or navigated. In this case, the function is invoked in the context of the newly attached frame.
The function is invoked after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed `Math.random`.
</td></tr>
<tr><td>
<span id="exposefunction">[exposeFunction(name, pptrFunction)](./puppeteer.page.exposefunction.md)</span>
</td><td>
</td><td>
The method adds a function called `name` on the page's `window` object. When called, the function executes `puppeteerFunction` in node.js and returns a `Promise` which resolves to the return value of `puppeteerFunction`.
If the puppeteerFunction returns a `Promise`, it will be awaited.
:::note
Functions installed via `page.exposeFunction` survive navigations.

Navigates the frame or page to the given `url`.
**Remarks:**
Navigation to `about:blank` or navigation to the same URL with a different hash will succeed and return `null`.
:::warning
Headless shell mode doesn't support navigation to a PDF document. See the [upstream issue](https://crbug.com/761295).
:::
In headless shell, this method will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not Found" and 500 "Internal Server Error". The status code for such responses can be retrieved by calling [HTTPResponse.status()](./puppeteer.httpresponse.status.md).

This method fetches an element with `selector`, scrolls it into view if needed, and then uses [Page.touchscreen](./puppeteer.page.md#touchscreen) to tap in the center of the element. If there's no element matching `selector`, the method throws an error.
**Remarks:**
Shortcut for [page.mainFrame().tap(selector)](./puppeteer.frame.tap.md).

This method is typically coupled with an action that triggers a device request from an api such as WebBluetooth.
:::caution
This must be called before the device request is made. It will not return a currently active device prompt.

Wait for the `selector` to appear in page. If at the moment of calling the method the `selector` already exists, the method will return immediately. If the `selector` doesn't appear after the `timeout` milliseconds of waiting, the function will throw.
**Remarks:**
The optional Parameter in Arguments `options` are:
- `visible`: A boolean wait for element to be present in DOM and to be visible, i.e. to not have `display: none` or `visibility: hidden` CSS properties. Defaults to `false`.
- `hidden`: Wait for element to not be found in the DOM or to be hidden, i.e. have `display: none` or `visibility: hidden` CSS properties. Defaults to `false`.
- `timeout`: maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can be changed by using the [Page.setDefaultTimeout()](./puppeteer.page.setdefaulttimeout.md) method.
