source
⬆
Loads static HTML or a URI (with optional headers) in the WebView. Note that static HTML will require setting originWhitelist
to ["*"]
.
The object passed to source
can have either of the following shapes:
Load uri
uri
(string) - The URI to load in theWebView
. 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 and Windows, 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 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 and Windows, this can only be used with POST requests.
Static HTML
Note that using static HTML requires the WebView property 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
Type | Required |
---|---|
object | No |
automaticallyAdjustContentInsets

injectedJavaScript
⬆
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
. Be sure
to set an onMessage
handler, even if it's a no-op, or the code will not be run.
Type | Required | Platform |
---|---|---|
string | No | iOS, Android, macOS, Windows |
To learn more, read the Communicating between JS and Native guide.
Kindly note: Windows does not have native support for alerts, as such any scripts to show an alert will not work.
Example:
Post message a JSON object of window.location
to be handled by onMessage
const INJECTED_JAVASCRIPT = `(function() {
window.ReactNativeWebView.postMessage(JSON.stringify(window.location));
})();`;
<WebView
source={{ uri: 'https://reactnative.dev' }}

onMessage={this.onMessage}
/>;
injectedJavaScriptBeforeContentLoaded
⬆
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
Warning On Android, this may work, but it is not 100% reliable (see #1609 and #1099).
Type | Required | Platform |
---|---|---|
string | No | iOS, macOS, Android (experimental) |
To learn more, read the Communicating between JS and Native guide.
Example:
Post message a JSON object of window.location

. window.ReactNativeWebView.postMessage
will be available at this time.
const INJECTED_JAVASCRIPT = `(function() {
window.ReactNativeWebView.postMessage(JSON.stringify(window.location));

⬆
Function that is invoked when the WebView

Type | Required | Platform |
---|---|---|
function | No | iOS and macOS WKWebView |
iOS Web views use a separate process to render and manage web content. WebKit calls this method when the process for the specified web view terminates for any reason. The reason is not necessarily a crash. For instance, since iOS WebViews are not included in the total RAM of the app, they can be terminated independently of the app to liberate memory for new apps the user is opening. It's not unexpected to have WebViews get terminated after a while in the background.
Example:
<WebView
source={{ uri: 'https://reactnative.dev' }}
onContentProcessDidTerminate={(syntheticEvent) => {
const { nativeEvent } = syntheticEvent;
console.warn('Content process terminated, reloading', nativeEvent);
this.refs.webview.reload();

Function passed to onScroll
is called with a SyntheticEvent wrapping a nativeEvent with these properties:
contentInset
contentOffset
contentSize
layoutMeasurement
velocity
zoomScale
originWhitelist
⬆
List of origin strings to allow being navigated to. The strings allow wildcards and get matched against just the origin (not the full URL).

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

: If the security origin's host of the permission request equals the host of the WebView's current URL, the permission is granted if it has been granted before. Otherwise, it gets denied.deny
grant
: The permission is granted if it has been granted before.prompt
Note that a grant may still result in a prompt, for example if the user has never been prompted for the permission before.
Type | Required | Platform |
---|---|---|
string | No | iOS |
Example:
<WebView mediaCapturePermissionGrantType={'grantIfSameHostElsePrompt'} />
If set to true
