  • Updated typings of the admin.messaging.WebpushNotification type to include all supported notification fields.

Version 5.12.1 - May 15, 2018

Version 5.12.0 - April 05, 2018

Authentication

Authentication

Version 5.10.0 - March 08, 2018

Cloud Messaging

Version 5.8.2 - January 30, 2018

  • Exposed admin.firestore.DocumentReference and admin.firestore.DocumentSnapshot types from the Admin SDK typings.

Version 5.7.0 - January 04, 2018

Authentication

  • A new revokeRefreshTokens() method for revoking refresh tokens issued to a user.

Cloud Firestore

  • Upgraded the Cloud Firestore client to the latest available version.

Version 5.4.3 - October 24, 2017

  • Fixed a regression in module loading that prevented using the Admin SDK in environments like AWS Lambda. This regression was introduced in the 5.4.0 release, which added a new dependency to Firestore and gRPC. This fix lazily loads Firestore and gRPC, thus enabling Admin SDK usage in the affected environments as long as no explicit attempts are made to use the Firestore API.

Version 5.4.2 - October 09, 2017

  • Upgraded the Cloud Firestore client dependency to 0.8.2, which resolves an issue with saving objects with nested document references.

Version 5.4.1 - October 03, 2017

Authentication

  • New type definitions for the arguments of createUser() and updateUser() methods.

Cloud Messaging

  • Redefined the arguments of sendToDevice() using intersection instead of overloading.

Version 5.1.0 - July 25, 2017

Authentication

  • Added the method getUserByPhoneNumber() to the admin.auth interface. This method enables retrieving user profile information by a phone number.
  • createUser() and updateUser() methods now accept a phoneNumber property, which can be used to create users with a phone number field and/or update the phone number associated with a user.
  • Added the phoneNumber field to admin.auth.UserRecord, which exposes the phone number associated with a user account.
  • Added the phoneNumber field to admin.auth.UserInfo, which exposes the phone number associated with a user account by a linked identity provider.

Version 5.0.1 - July 12, 2017

  • Improved the error messages thrown in the case of network and RPC errors. These errors now include outgoing HTTP request details that make it easier to localize and debug issues.

Authentication

  • Implemented support in the user management API for handling photo URLs with special characters.

Version 5.0.0 - May 17, 2017

Initialization

  • The deprecated serviceAccount property in the admin.App.Options type has been removed in favor of the credential property.
  • Initializing the SDK without setting a credential results in an exception.
  • Initializing the SDK with a malformed private key string results in an exception.

Version 4.2.0 - April 04, 2017

Cloud Messaging

Version 4.1.4 - March 28, 2017

Authentication

Realtime Database

  • Fixed an issue which could cause infinite loops when using push() with no arguments.

Version 4.1.3 - March 7, 2017

  • Fixed incorrect usage of undefined - as opposed to void - in several places in the TypeScript typings.
  • Added missing properties to the TypeScript typings for DecodedIdToken.
  • Fixed issues when using some types with the TypeScript strictNullChecks option enabled.
  • Removed incorrect admin.Promise type from the TypeScript typings in favor of the Node.js built-in Promise type, which the SDK actually uses.
  • Added error codes to all app-level errors. All errors in the SDK now properly implement the FirebaseError interface.
  • Improved error handling when initializing the SDK with a credential that cannot generate valid access tokens.
  • Added new admin.database.EventType to the TypeScript typings.

Realtime Database

  • Improved how the Realtime Database reports errors when provided with various types of invalid credentials.

Version 4.1.2 - March 2, 2017

Authentication

  • Improved input validation and error messages for all user management methods.
  • verifyIdToken() now works with non-cert credentials, assuming the GCLOUD_PROJECT environment variable is set to your project ID, which is the case when running on Google infrastructure such as Google App Engine and Google Compute Engine.

Realtime Database

Cloud Messaging

Version 4.1.1 - February 14, 2017

  • Added in missing TypeScript typings for the FirebaseError.toJSON() method.

Authentication

  • Fixed issue with createUser() which sometimes caused multiple users to share the same email.

Version 4.1.0 - February 2, 2017

  • Added in missing TypeScript typings for the toJSON() method off of several objects.

Cloud Messaging

Version 4.0.6 - January 24, 2017

Initialization

  • Fixed an issue which caused importing the library via the ES2015 import syntax (import * as admin from "firebase-admin") to not work properly.

Version 4.0.5 - January 17, 2017

  • TypeScript support has been greatly improved. Typings for the Realtime Database are now available and all other known issues with incorrect or incomplete type information have been resolved.

Initialization

  • Fixed an issue which caused the SDK to appear to hang when provided with a credential that generated invalid access tokens. The most common cause of this was using a credential whose access had been revoked. Now, an error will be logged to the console in this scenario.

Authentication

  • The error message for an auth/internal-error error now includes the raw server response to more easily debug and track down unhandled errors.
  • Fixed an issue that caused an auth/internal-error error to be thrown when calling getUser() or getUserByEmail() for a user without a creation date.
  • Fixed an issue which caused an auth/internal-error error to be thrown when calling createUser() with an email that corresponds to an existing user.
  • Fixed an issue which caused an auth/internal-error error to be thrown when calling Authentication methods with a credential with insufficient permission. Now, an auth/insufficient-permission error will be thrown instead.

Version 4.0.4 - December 6, 2016

Authentication

  • Fixed an issue that caused several Authentication methods to throw an error when provided with inputs containing Unicode characters.

Version 4.0.3 - November 21, 2016

Initialization

  • Fixed an issue that caused a null value for the databaseAuthVariableOverride property to be ignored when passed as part of the first argument to initializeApp(), which caused the app to still have full admin access. Now, passing this value has the expected behavior: the app has unauthenticated access to the Realtime Database, and behaves as if no user is logged into the app.

Authentication

  • Fixed an issue that caused an auth/invalid-uid error to be thrown for valid uid values passed to several Authentication methods.

Version 4.0.2 - November 15, 2016

  • Improved error messages throughout the Admin Node.js SDK.
  • Upgraded dependencies so that the Admin Node.js SDK no longer throws warnings for using deprecated Buffer APIs in Node.js 7.x.x.

Version 4.0.1 - November 9, 2016

  • Fixed issue which caused the 4.0.0 release to not include the README.md and npm-shrinkwrap.json files.

Version 4.0.0 - November 7, 2016

  • The Admin Node.js SDK (available on npm as firebase-admin) is a new SDK which replaces and expands the admin capabilities of the standard firebase npm module. See Add the Firebase Admin SDK to your Server to get started.
  • This version does not include the README.md and npm-shrinkwrap.json files. This was fixed in version 4.0.1.

Initialization

Authentication

  • A new Admin API for managing your Firebase Authentication users is now available. This API lets you manage your users without using their existing credentials, and without worrying about client-side rate limiting. The new methods included in this API are getUser(), getUserByEmail(), createUser(), updateUser(), and deleteUser(). See Manage Users for more details.
  • The createCustomToken() method is now asynchronous, returning a Promise<string> instead of a string.
