Dynamic Links

Firebase Dynamic Links allows you to create and receive links on both Android and iOS platforms. Assuming the installation instructions have been followed, Firebase Dynamic Links is ready to go.

All Dynamic Links operations are accessed via firebase.links()

Create Dynamic Links

RNFirebase mimics Firebase's REST API for Dynamic Links creation. The differences from the REST API are:

1. The input for the methods is a javascript object instead of a JSON object.
2. The response contains the URL string only.
3. There is no dynamicLinkInfo element. Instead, all of the elements under it were moved to be under the top-level.

Methods

createDynamicLink(parameters: Object): Promise<String>

Creates a long dynamic link.

firebase.links().createDynamicLink({
  dynamicLinkDomain: "abc123.app.goo.gl",
  link: "https://example.com?param1=foo&param2=bar",
  androidInfo: {
    androidPackageName: "com.example.android"
  },
  iosInfo: {
    iosBundleId: "com.example.ios"
  }
}).
then((url) => {
  // ...
});

createShortDynamicLink(parameters: Object): Promise<String>

Creates a short dynamic link.

firebase.links().createShortDynamicLink({
  dynamicLinkDomain: "abc123.app.goo.gl",
  link: "https://example.com?param1=foo&param2=bar",
  androidInfo: {
    androidPackageName: "com.example.android"
  },
  iosInfo: {
    iosBundleId: "com.example.ios"
  }
}).
then((url) => {
  // ...
});

Parameters

{
  dynamicLinkDomain: 'string',

    androidFallbackLink: 'string',
    androidMinPackageVersionCode: 'string',

    iosFallbackLink: 'string',
    iosCustomScheme: 'string',
    iosIpadFallbackLink: 'string',

    socialTitle: 'string',
    socialDescription: 'string',
    socialImageLink: 'string',
  },
  suffix: {
    option: 'string',
  },
}

please note:

1. dynamicLinkDomain and link are mandatory fields. In addition, when using androidInfo or iosInfo, androidPackageName and iosBundleId are mandatory (respectively).
2. In oppose to the REST API, There is no dynamicLinkInfo element. Instead, all of the elements under it were moved to be under the top-level.

Methods

getInitialLink(): Promise<String>

Call getInitialLink to access the URL that the app has been launched from. If the app was not launched from a URL, the return value is null.

firebase.links().getInitialLink().then((url) => {
  //...
});

onLink(listener: Function<String>): Function

On a new URL, the payload URL is passed to the listener callback. This method is only triggered when the app is running. Use getInitialLink for URLs which cause the app to open. In order to subscribe to the listener, call to the method with a callback and save the returned function. When you want to unsubscribe, just call the function that returned at subscription.

// Subscribe
const unsubscribe = firebase.links().onLink((url) => {
  //...
});

// Unsubscribe
unsubscribe();
