## Getting started

`$ npm install react-native-inappbrowser-reborn --save`

### Mostly automatic installation

#### Using React Native >= 0.60
Linking the package manually is not required anymore with [Autolinking](https://github.com/react-native-community/cli/blob/master/docs/autolinking.md).

- **iOS Platform:**

  `$ cd ios && pod install && cd ..` # CocoaPods on iOS needs this extra step

- **Android Platform with Android Support:**

  Using [Jetifier tool](https://github.com/mikehardy/jetifier) for backward-compatibility.

  Modify your **android/build.gradle** configuration:
  ```
  buildscript {
    ext {
      buildToolsVersion = "28.0.3"
      minSdkVersion = 16
      compileSdkVersion = 28
      targetSdkVersion = 28
      // Only using Android Support libraries
      supportLibVersion = "28.0.0"
    }
  ```

- **Android Platform with AndroidX:**

  Modify your **android/build.gradle** configuration:
  ```
  buildscript {
    ext {
      buildToolsVersion = "30.0.2"
      minSdkVersion = 21
      compileSdkVersion = 30
      targetSdkVersion = 30
      ndkVersion = "21.4.7075529"
      // Remove 'supportLibVersion' property and put specific versions for AndroidX libraries
      androidXAnnotation = "1.2.0"
      androidXBrowser = "1.3.0"
      // Put here other AndroidX dependencies
    }
  ```

## Usage

Methods       | Action
------------- | ------
`open`        | Opens the url with Safari in a modal on iOS using **SFSafariViewController**, and Chrome in a new custom tab on Android. On iOS, the modal Safari will not share cookies with the system Safari.
`close`       | Dismisses the system's presented web browser.
`openAuth`    | Opens the url with Safari in a modal on iOS using **SFAuthenticationSession/ASWebAuthenticationSession**, and Chrome in a new custom tab on Android. On iOS, the user will be asked whether to allow the app to authenticate using the given url **(OAuth flow with deep linking redirection)**.
`closeAuth`   | Dismisses the current authentication session.
`isAvailable` | Detect if the device supports this plugin.
`onStart`   | Initialize a bound background service so the application can communicate its intention to the browser. After the service is connected, the client can be used to Warms up the browser to make navigation faster and indicates that a given URL may be loaded in the future. - Android Only.
`warmup`   | Warm up the browser process - Android Only.
`mayLaunchUrl` | Tells the browser of a likely future navigation to a URL. The most likely URL has to be specified first. Optionally, a list of other likely URLs can be provided. They are treated as less likely than the first one, and have to be sorted in decreasing priority order. These additional URLs may be ignored. All previous calls to this method will be deprioritized - Android Only.

...
  async sleep(timeout) {
    return new Promise(resolve => setTimeout(resolve, timeout))
  }
  async openLink() {
    try {
      const url = 'https://github.com/proyecto26'
      if (await InAppBrowser.isAvailable()) {
        const result = await InAppBrowser.open(url, {

            endEnter: 'slide_in_left',
            endExit: 'slide_out_right'
          },
          headers: {
            'my-custom-header': 'my custom header value'
          }
        })
        await this.sleep(800);
        Alert.alert(JSON.stringify(result))
      }
      else Linking.openURL(url)
    } catch (error) {
      Alert.alert(error.message)
    }
  }
...
```

### Android Optimizations

On Android, you can warmup the in app browser client to make it launch siginificantly faster. To do so, add the following to your `MainActivity`

```java
import com.proyecto26.inappbrowser.RNInAppBrowserModule;

public class MainActivity extends ReactActivity {

  @Override
  protected void onStart() {
    super.onStart();
    RNInAppBrowserModule.onStart(this);
  }

}
```

You can further optimize performance and pre-render pages [by providing the urls that the user is likely to open](https://developer.chrome.com/docs/android/custom-tabs/best-practices/#pre-render-content).

```javascript
// Do not call this every time the component render
useEffect(() => {
  InAppBrowser.mayLaunchUrl("Url user has high chance to open", ["Other urls that user might open ordered by priority"]);
}, []);
```

### Authentication Flow using Deep Linking

In order to redirect back to your application from a web browser, you must specify a unique URI to your app. To do this,
define your app scheme and replace `my-scheme` and `my-host` with your info.

- Enable deep linking (Android) - **[AndroidManifest.xml](https://github.com/proyecto26/react-native-inappbrowser/blob/main/example/android/app/src/main/AndroidManifest.xml#L23)**
```
<activity
  ...
  android:launchMode="singleTask">
  <intent-filter>
      <action android:name="android.intent.action.VIEW" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
      <data android:scheme="my-scheme" android:host="my-host" android:pathPrefix="" />
  </intent-filter>
</activity>
```

- Enable deep linking (iOS) - **[Info.plist](https://github.com/proyecto26/react-native-inappbrowser/blob/main/example/ios/example/Info.plist#L23)**
```
<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string>my-scheme</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>my-scheme</string>
    </array>
  </dict>
</array>
```

- utilities.js
```javascript
import { Platform } from 'react-native'
export const getDeepLink = (path = '') => {
  const scheme = 'my-scheme'
  const prefix = Platform.OS == 'android' ? `${scheme}://my-host/` : `${scheme}://`
  return prefix + path
}
```
- App.js ([Using react-navigation with Deep Linking](https://reactnavigation.org/docs/en/deep-linking.html))
```javascript
import { Root } from 'native-base'
import { createStackNavigator } from 'react-navigation'
import { getDeepLink } from './utilities'

const Main = createStackNavigator(
  {
    SplashComponent: { screen: SplashComponent },
    LoginComponent: { screen: LoginComponent },
    HomeComponent: { screen: HomeComponent },
    CallbackComponent: { //Redirect users to the Home page if they are authenticated, otherwise to Login page...
      screen: CallbackComponent,
      path: 'callback/' //Enable Deep linking redirection to get the auth_token
    }
  },
  {
    index: 0,
    initialRouteName: 'SplashComponent',
    headerMode: 'none'
  }
)
...
  render() {
    return (
      <Root>
        <Main uriPrefix={getDeepLink()} />
      </Root>
    )
  }
...
```

- LoginComponent
```javascript
import { Linking } from 'react-native'
import { InAppBrowser } from 'react-native-inappbrowser-reborn'
import { getDeepLink } from './utilities'
...
  async onLogin() {
    const deepLink = getDeepLink('callback)
    const url = `https://my-auth-login-page.com?redirect_uri=${deepLink}`
    try {
      if (await InAppBrowser.isAvailable()) {
        InAppBrowser.openAuth(url, deepLink, {
          // iOS Properties
          ephemeralWebSession: false,
          // Android Properties
          showTitle: false,
          enableUrlBarHiding: true,
          enableDefaultShare: false
        }).then((response) => {
          if (
            response.type === 'success' &&
            response.url
          ) {
            Linking.openURL(response.url)
          }
        })
      } else Linking.openURL(url)
    } catch (error) {
      Linking.openURL(url)
    }
  }
...
```

- SplashComponent
```javascript
...
  async componentDidMount() {
    // Play Lottie Animation :)

    // Validate the stored access token (Maybe with a request)
    // Redirect the user to the Home page if the token is still valid
    // Otherwise redirect to the Login page
  }
...
```

- CallbackComponent
```javascript
...
  async componentDidMount() {
    // Play Lottie Animation :)
    try {
      await this.loadUserInfo()
      // Redirect to the Home page
    } catch (error) {
      // Show error and redirect the user to the Login page
    }
  }

  async loadUserInfo() {
    const { navigation } = this.props
    const { state: { params } } = navigation
    const { code, error } = params || {}

    if (code) {
      // Get and Save the access token request, user info...
    }
    else {
      return Promise.reject(new Error(error))
    }
  }
...
```

### StatusBar

The StatusBar will keep the last one provided in your app. So if the StatusBar is `dark-content` before you open the browser this will keep it.

Starting with React Native 0.59 onwards, there is a simpler way of handling this update, without the need of patching StatusBar.
```javascript
  async openInBrowser(url) {
    try {
      const oldStyle = StatusBar.pushStackEntry({ barStyle: 'dark-content', animated: false });
      await InAppBrowser.open(url)
      StatusBar.popStackEntry(oldStyle);
    } catch (error) {
      Alert.alert(error.message)
    }
  })
```

For previous versions, you can still apply the method described below.

If you want to change before opening you can do something like

```javascript
  async openInBrowser(url) {
    try {
      StatusBar.setBarStyle('dark-content')
      await InAppBrowser.open(url)
    } catch (error) {
      Alert.alert(error.message)
    }
  })
```

If you need to restore the old bar style, after the browser is dismissed, you can try and patch the StatusBar.setBarStyle function to store the old value like so:

```js
// patch StatusBar.setBarStyle to make style accessible
const _setBarStyle = StatusBar.setBarStyle
StatusBar.setBarStyle = (style) => {
  StatusBar.currentStyle = style
  _setBarStyle(style)
}
```

You can than restore the old bar style after the browser has been dismissed like this:

```javascript
  async openInBrowser(url) {
    try {
      const oldStyle = StatusBar.currentStyle
      StatusBar.setBarStyle('dark-content')
      await InAppBrowser.open(url)
      if(oldStyle) StatusBar.setBarStyle(oldStyle)
    } catch (error) {
      Alert.alert(error.message)
    }
  })
```

### Authentication

Using in-app browser tabs (like SFAuthenticationSession/ASWebAuthenticationSession and Android Custom Tabs) where available. Embedded user-agents, known as web-views (like UIWebView and WKWebView), are explicitly not supported due to the usability and security reasons documented in [Section 8.12 of RFC 8252](https://tools.ietf.org/html/rfc8252#section-8.12).
