app.App interface

A Firebase app holds the initialization information for a collection of services.

Do not call this constructor directly. Instead, use initializeApp() to create an app.

Signature:

interface App extends AppCore 

Extends: AppCore

Methods

app.App.appCheck()

Signature:

appCheck(): appCheck.AppCheck;

Returns:

appCheck.AppCheck

app.App.auth()

Signature:

auth(): auth.Auth;

Returns:

auth.Auth

app.App.database()

Signature:

database(url?: string): database.Database;

Parameters

Returns:

database.Database

app.App.delete()

Renders this local FirebaseApp unusable and frees the resources of all associated services (though it does *not* clean up any backend resources). When running the SDK locally, this method must be called to ensure graceful termination of the process.

Signature:

delete(): Promise<void>;

Returns:

Promise<void>

Example

app.delete()
  .then(function() {
    console.log("App deleted successfully");
  })
  .catch(function(error) {
    console.log("Error deleting app:", error);
  });
