# Reference

## Props

### `source`[⬆](#props-index)<!-- Link generated with jump2header -->

Loads static HTML or a URI (with optional headers) in the WebView. Note that static HTML will require setting [`originWhitelist`](Reference.md#originwhitelist) to `["*"]`.

The object passed to `source` can have either of the following shapes:

**Load uri**

- `uri` (string) - The URI to load in the `WebView`. Can be a local or remote file, and can be changed with React state or props to navigate to a new page.
- `method` (string) - The HTTP Method to use. Defaults to GET if not specified. On Android, the only supported methods are GET and POST.
- `headers` (object) - Additional HTTP headers to send with the request. On Android, this can only be used with GET requests. See the [Guide](Guide.md#setting-custom-headers) for more information on setting custom headers.
- `body` (string) - The HTTP body to send with the request. This must be a valid UTF-8 string, and will be sent exactly as specified, with no additional encoding (e.g. URL-escaping or base64) applied. On Android, this can only be used with POST requests.

**Static HTML**

_Note that using static HTML requires the WebView property [originWhiteList](Reference.md#originWhiteList) to `['*']`. For some content, such as video embeds (e.g. Twitter or Facebook posts with video), the baseUrl needs to be set for the video playback to work_

- `html` (string) - A static HTML page to display in the WebView.
- `baseUrl` (string) - The base URL to be used for any relative links in the HTML. This is also used for the origin header with CORS requests made from the WebView. See [Android WebView Docs](https://developer.android.com/reference/android/webkit/WebView#loadDataWithBaseURL)

| Type   | Required |
| ------ | -------- |
| object | No       |

---

### `automaticallyAdjustContentInsets`[⬆](#props-index)<!-- Link generated with jump2header -->

Controls whether to adjust the content inset for web views that are placed behind a navigation bar, tab bar, or toolbar. The default value is `true`.

| Type | Required | Platform |
| ---- | -------- | -------- |
| bool | No       | iOS      |

---

### `injectedJavaScript`[⬆](#props-index)<!-- Link generated with jump2header -->

Set this to provide JavaScript that will be injected into the web page after the document finishes loading, but before other subresources finish loading.

Make sure the string evaluates to a valid type (`true` works) and doesn't otherwise throw an exception.

On iOS, see [`WKUserScriptInjectionTimeAtDocumentEnd`](https://developer.apple.com/documentation/webkit/wkuserscriptinjectiontime/wkuserscriptinjectiontimeatdocumentend?language=objc). Be sure
to set an [`onMessage`](Reference.md#onmessage) handler, even if it's a no-op, or the code will not be run.

| Type   | Required | Platform            |
| ------ | -------- | ------------------- |
| string | No       | iOS, Android, macOS |

To learn more, read the [Communicating between JS and Native](Guide.md#communicating-between-js-and-native) guide.

Example:

Post message a JSON object of `window.location` to be handled by [`onMessage`](Reference.md#onmessage)

```jsx
const INJECTED_JAVASCRIPT = `(function() {
    window.ReactNativeWebView.postMessage(JSON.stringify(window.location));
})();`;

<WebView
  source={{ uri: 'https://reactnative.dev' }}
  injectedJavaScript={INJECTED_JAVASCRIPT}
  onMessage={this.onMessage}
/>;
```

---

### `injectedJavaScriptBeforeContentLoaded`[⬆](#props-index)<!-- Link generated with jump2header -->

Set this to provide JavaScript that will be injected into the web page after the document element is created, but before other subresources finish loading.

Make sure the string evaluates to a valid type (`true` works) and doesn't otherwise throw an exception.

On iOS, see [`WKUserScriptInjectionTimeAtDocumentStart`](https://developer.apple.com/documentation/webkit/wkuserscriptinjectiontime/wkuserscriptinjectiontimeatdocumentstart?language=objc)

| Type   | Required | Platform   |
| ------ | -------- | ---------- |
| string | No       | iOS, macOS |

To learn more, read the [Communicating between JS and Native](Guide.md#communicating-between-js-and-native) guide.

Example:

Post message a JSON object of `window.location` to be handled by [`onMessage`](Reference.md#onmessage). `window.ReactNativeWebView.postMessage` _will_ be available at this time.

```jsx
const INJECTED_JAVASCRIPT = `(function() {
    window.ReactNativeWebView.postMessage(JSON.stringify(window.location));
})();`;

<WebView
  source={{ uri: 'https://reactnative.dev' }}

  onMessage={this.onMessage}
/>;

You may also use the string shortcuts `"normal"` and `"fast"` which match the underlying iOS settings for `UIScrollViewDecelerationRateNormal` and `UIScrollViewDecelerationRateFast` respectively:

- normal: 0.998
- fast: 0.99 (the default for iOS web view)

| Type   | Required | Platform |
| ------ | -------- | -------- |
| number | No       | iOS      |

---

### `domStorageEnabled`[⬆](#props-index)<!-- Link generated with jump2header -->

| ---- | -------- |
| bool | No       |

---

### `javaScriptCanOpenWindowsAutomatically`[⬆](#props-index)<!-- Link generated with jump2header -->

A Boolean value indicating whether JavaScript can open windows without user interaction. The default value is `false`.

| Type | Required |
| ---- | -------- |
| bool | No       |

---

### `androidHardwareAccelerationDisabled`[⬆](#props-index)<!-- Link generated with jump2header -->

**Deprecated.** Use the `androidLayerType` prop instead. 

| Type | Required | Platform |
| ---- | -------- | -------- |
| bool | No       | Android  |

---

### `androidLayerType`[⬆](#props-index)<!-- Link generated with jump2header -->

Specifies the layer type. 

Possible values for `androidLayerType` are:

- `none` (default) - The view does not have a layer.
- `software` - The view has a software layer. A software layer is backed by a bitmap and causes the view to be rendered using Android's software rendering pipeline, even if hardware acceleration is enabled.
- `hardware` - The view has a hardware layer. A hardware layer is backed by a hardware specific texture and causes the view to be rendered using Android's hardware rendering pipeline, but only if hardware acceleration is turned on for the view hierarchy.

Avoid setting both `androidLayerType` and `androidHardwareAccelerationDisabled` props at the same time, as this may cause undefined behaviour.

| Type   | Required | Platform |
| ------ | -------- | -------- |
| string | No       | Android  |

---

### `mixedContentMode`[⬆](#props-index)<!-- Link generated with jump2header -->

Possible values for `mixedContentMode` are:

- `never` (default) - WebView will not allow a secure origin to load content from an insecure origin.
- `always` - WebView will allow a secure origin to load content from any other origin, even if that origin is insecure.
- `compatibility` - WebView will attempt to be compatible with the approach of a modern web browser with regard to mixed content.

| Type   | Required | Platform |
| ------ | -------- | -------- |
| string | No       | Android  |

---

### `thirdPartyCookiesEnabled`[⬆](#props-index)<!-- Link generated with jump2header -->

### `cacheMode`[⬆](#props-index)<!-- Link generated with jump2header -->

- `LOAD_NO_CACHE` - Don't use the cache, load from the network.

### `onFileDownload`[⬆](#props-index)<!-- Link generated with jump2header -->
This property is iOS-only.

Function that is invoked when the client needs to download a file.

iOS 13+ only: If the webview navigates to a URL that results in an HTTP
response with a Content-Disposition header 'attachment...', then
this will be called.

iOS 8+: If the MIME type indicates that the content is not renderable by the
webview, that will also cause this to be called. On iOS versions before 13,
this is the only condition that will cause this function to be called.

The application will need to provide its own code to actually download
the file.

If not provided, the default is to let the webview try to render the file.

Example:

```jsx
<WebView
  source={{ uri: 'https://reactnative.dev' }}
  onFileDownload={({ nativeEvent: { downloadUrl } }) => {
    // You use downloadUrl which is a string to download files however you want.
