Firebase JavaScript SDK Release Notes

To review release notes for the Firebase console and for other Firebase platforms and related SDKs, refer to the Firebase Release Notes.

Version 12.2.1 - August 28, 2025

AI Logic

  • Fixed an issue that caused TypeScript compilation errors.

Version 12.2.0 - August 28, 2025

AI Logic

  • Add support for the Gemini Live API.

  • Add thoughtSummary() convenience method to EnhancedGenerateContentResponse.

  • Add support for limited-use tokens with Firebase App Check. These limited-use tokens are required for an upcoming optional feature called replay protection. We recommend enabling the usage of limited-use tokens now so that when replay protection becomes available, you can enable it sooner because more of your users will be on versions of your app that send limited-use tokens.

  • Fixed an issue where AIError messages were too long after including an entire response body.

  • Added 'includeSafetyAttributes' field to Predict request payloads.

  • Excluded ChromeAdapterImpl code from Node entry point.

Cloud Firestore

  • Fixed a bug where a rejected promise with an empty message in a transaction would cause a timeout. See GitHub Issue #9147.

Cloud Functions for Firebase Client SDK

  • Fixed an issue which caused a CORS error in Firebase Studio when connected to emulators.

Version 12.1.0 - August 7, 2025

AI Logic

  • Added hybrid inference options to AI Logic. This provides options to perform inference tasks using the Prompt API in browsers that have the Prompt API enabled.

Performance Monitoring

  • Fixed errors thrown when capturing long target element names for out-of-the-box metrics. See GitHub Issue #9136.

Version 12.0.0 - July 17, 2025

  • Updated Node.js "engines" version to require a minimum of Node 20.

  • Updated the SDK to use ES2020. Developers whose apps are not using ES2020 or higher may need to update their tooling or configuration.

  • Removed the firebase/vertexai import alias. All the functionality is still available under the new name: firebase/ai, although some methods may be renamed (see AI Logic notes below).

AI Logic

  • Removed methods and symbols with the VertexAI name in them such as getVertexAI or VertexAIError. These were deprecated in 11.8.0 and were just wrappers on the newly introduced methods with the AI name, such as getAI or AIError.

  • Added support for Grounding with Google Search.

  • Added support for the Thinking Budget feature.

  • Added support for anyOf schemas.

  • Converted each enum export to a combination of a const map and a string literal type. This makes the constants available to non-TypeScript users and allows tree-shaking of unused variables.

  • Removed GroundingAttribution, which had previously been deprecated.

  • Fixed typings for functionDeclaration.parameters to prevent the use of optionalProperties when using an object literal.

Cloud Firestore

  • Reverted a fix for an issue where Cloud Firestore would send undefined for a document snapshot if the "clear site data" button was pressed in the web browser. This fix was introduced in v11.6.1 but inadvertently caused IndexedDB issues for some customers. See GitHub Issue #9165.

  • Further improved performance of UTF-8 string ordering logic, which had degraded in v11.3.0, was reverted in v11.3.1, and was reintroduced with some improvements in v11.5.0.

  • Fixed a regression where the SDK did not re-connect to IndexedDb after a disconnect.

Version 11.10.0 - June 26, 2025

  • Added React Native entry point.

AI Logic

  • Added deprecation label to totalBillableCharacters. totalTokens should be used instead.

Cloud Firestore

  • Added support for Firestore result types to be serialized with toJSON and then deserialized with fromJSON methods on the objects.
  • Added support to resume onSnapshot listeners in the CSR phase based on serialized DataSnapshots and QuerySnapshots built in the SSR phase.
  • Internal listener registration change for IndexedDB versionchange events.

Cloud Storage

  • Fixed CORS error that occurred in Firebase Studio.

Version 11.9.1 - June 10, 2025

Authentication

  • Fixed a Firebase Studio issue where Firebase Auth cookie refresh attempts issued in Firebase Studio resulted in CORS errors.

Cloud Storage

  • Fixed a Firebase Studio issue that didn't properly populate cookies for Storage users.

Version 11.9.0 - June 5, 2025

AI Logic

  • Added title, maximum, minimum, maxItems, minItems, and propertyOrdering to Schema.
  • Added HarmBlockThreshold.OFF support.

Cloud Firestore

  • Clean up leaked WebChannel instances when the Firestore instance is terminated.

Version 11.8.0 - May 20, 2025

  • The FirebaseApp setting automaticDataCollectionEnabled now defaults to true. This setting was previously only used by App Check and won't change the default behavior in App Check.

Cloud Firestore

  • Fixed a cache issue in Safari/WebKit that occurs when client-side indexing is used.

AI Logic

  • Initial release of the Firebase AI Logic SDK (@firebase/ai). This SDK replaces the previous Vertex AI in Firebase SDK (@firebase/vertexai) to accommodate the evolving set of supported features and services. The new Firebase AI Logic SDK provides preview support for the Gemini Developer API, including its free tier offering. Using the Firebase AI Logic SDK with the Vertex AI Gemini API is still generally available (GA).

    To start using the new SDK, use the getAI() instance getter imported from ’firebase/ai’. See details in the migration guide.

  • Added support for Gemini multimodal output.

  • Fixed an issue where GenerationConfig was not inherited from ChatSession.

Version 11.7.1 - May 7, 2025

  • Rolled back the change in 11.7.0 that set the value of automaticDataCollectionEnabled to true. Due to a backend setting not being ready yet, this will cause errors in Vertex AI in Firebase requests. This change will be restored when the backend is ready.

Version 11.7.0 - May 7, 2025

  • The FirebaseApp setting automaticDataCollectionEnabled now defaults to true. This setting was previously only used by App Check and won't change the default behavior in App Check.

Version 11.6.1 - April 24, 2025

Authentication

  • Fixed an issue where ActionCodeURL was not populating languageCode from the URL. Fixes GitHub Issue #8912.

Data Connect

  • Resolved a 'cannot extend private constructor' build error that occurred when using the DataConnectError and DataConnectOperationError types. See GitHub PR #8898.

Cloud Firestore

  • Fixed 'window is not defined' error when calling clearIndexedDbPersistence from a service worker. Fixes GitHub Issue #6465.
  • Fixed an issue where Firestore would produce undefined for document snapshot data if using IndexedDB persistence and "clear site data" (or equivalent) was selected in the web browser. Fixes GitHub Issue #8953.
  • Added unique IDs and state information into fatal error messages instead of the generic "unexpected state" message.

Version 11.6.0 - March 31, 2025

Authentication

  • Added Persistence.COOKIE, a new persistence method backed by cookies. The browserCookiePersistence implementation is designed to be used in conjunction with middleware that ensures both your front and backend authentication state remain synchronized.

Data Connect

  • Exposed partial errors to the user.

Vertex AI in Firebase

  • The SDK now throws an error when initializing models if appId is not defined in the given Vertex AI in Firebase instance.

  • Labeled GroundingAttribution as deprecated.

Version 11.5.0 - March 20, 2025

App Check

  • The getToken() method now throws internalError strings that were previously internally suppressed. Fixes GitHub issue #8822.

Cloud Firestore

Data Connect

  • Updated requests to point to the v1 backend endpoints instead of v1beta.

Performance Monitoring

Realtime Database

Remote Config

  • Added support for initial state hydration from SSR contexts.

Version 11.3.1 - February 11, 2025

Cloud Firestore

  • Reverted a change to use UTF-8 encoding in string comparisons because it caused a performance issue. Fixes GitHub issue #8778.

Version 11.3.0 - February 6, 2025

  • Added an appCheckToken parameter to FirebaseServerAppSettings. FirebaseServerApp will use the token when making service requests, unblocking the use of App Check enforced products in SSR environments.

Authentication

  • Added ActionCodeSettings.linkDomain to customize the Firebase Hosting link domain that is used in mobile out-of-band email action flows. Also, deprecated ActionCodeSettings.dynamicLinkDomain.

Performance Monitoring

  • Collect web vital metrics (INP,CLS,LCP) as part of page load event.

Realtime Database

  • Fixed a potential negative offset when calculating last reconnect times. This could cause lengthy reconnect delays in some scenarios. Fixes GitHub Issue #8718.

Cloud Firestore

  • Fixed an issue where the SDK's string sorting differed from the server's (UTF-8 byte order) for document fields and map/document keys, resolving a mismatch caused by special characters.

Version 11.2.0 - January 16, 2025

Data Connect

  • Usage of PromiseLike has been replaced with Promise.

Remote Config

  • Added support for custom signal targeting. Use the setCustomSignals API and to set custom signals that can be targeted using the new custom signal condition type in the Remote Config console.

  • Clear fetch timeout after request completion. Fixes an issue that caused Node.js scripts to hang on exit due to a pending timeout.

Version 11.0.2 - November 14, 2024

  • Upgraded to TypeScript 5.5.4.

Cloud Firestore

  • Prevent a possible condition of slow snapshots, caused by a rapid series of document update(s) followed by a delete. Fixes GitHub Issue #8474.

Vertex AI in Firebase

  • Update to new base URL in documentation.
  • Remove indentation in API Not Enabled error.
  • Send App Check dummy token in header if there is an App Check getToken error.

Version 11.0.1 - October 22, 2024

Realtime Database

  • Bumped @firebase/database-compat by a major version to ensure downstream libraries like firebase-admin don't automatically pick up the Node.js engines update in package.json.

Version 11.0.0 - October 21, 2024

  • Vertex AI in Firebase is now Generally Available (GA) and can be used in production apps.

    Use the Vertex AI in Firebase SDK to call the Vertex AI Gemini API directly from your app. This client SDK is built specifically for use with Web apps, offering security options against unauthorized clients as well as integrations with other Firebase services.

  • The SDK no longer supports versions of Node.js below version 18. engines fields in all package.json files have been updated to reflect this.

  • Removed ES5 bundles. The minimum required ES version is now ES2017.

  • Removed usage of undici and node-fetch dependencies in our Node.js bundles, replacing them with the native Node.js fetch implementation.

Version 10.13.2 - September 18, 2024

Authentication

  • Suppress the use of the parameter referrerPolicy within fetch requests originating from Cloudflare Workers. Cloudflare Worker environments do not support this parameter and all Auth operations would silently fail. Fixes GitHub Issue #8355.

Cloud Firestore

  • Fix an issue with metadata fromCache defaulting to true when listening to cache in multiple browser tabs. See GitHub PR #8343.

Version 10.13.1 - August 29, 2024

Cloud Functions for Firebase Client SDK

Cloud Firestore

  • Add support for reading and writing Firestore vectors. See GitHub PR #8215.

Authentication

  • Remove localStorage synchronization on storage events in Safari iframes. See GitHub PR #8408.

Cloud Storage

Version 10.12.5 - August 1, 2024

  • Reverted the change that added the safevalues library, as it is not compatible with ES5 bundles. We will return to using safevalues when we migrate all our builds away from ES5.

  • Properly handle the case in app-compat checks where window exists but self does not. (This occurs in Ionic Stencil's Jest preset, for example.)

  • Fixed typos in documentation and some internal variables and parameters.

Version 10.12.4 - July 18, 2024

  • The SDK now uses the safevalues library to sanitize HTML vulnerable to XSS.

Version 10.12.3 - July 3, 2024

  • Updated browser environment detection logic in firebase/util to allow for the experimental use of FirebaseServerApp instances in edge runtimes. See GitHub Issue #8299.
  • Guard the use of FinalizationRegistry in FirebaseServerApp initialization based on the availability of FinalizationRegistry in the JavaScript runtime. See GitHub Issue #8299.
  • The FirebaseServerAppSettings.name field inherited from FirebaseAppSettings is now omitted instead of overloading the value as undefined. This fixes a TypeScript compilation error. For more information, see GitHub Issue #8336.

Cloud Firestore

  • Fixed a metadata sync issue with multi-tab persistence and snapshot listeners. See GitHub Issue #8314.
  • Fixed a typo in the package.json of webchannel-wrapper that caused bloom-blob to be missing the esm5 specifier. See GitHub Issue #8319.

Firebase AI Logic

Version 10.12.2 - May 27, 2024

Authentication

  • Changed types paths to point to rolled-up public d.ts files. This fixes TypeScript compilation errors in the web extension and cordova bundles. See GitHub Issue #8222.

Firebase AI Logic

  • Changed types paths to point to point to rolled-up public d.ts files. This fixes some TypeScript compiler errors. See GitHub PR #8256

  • Update jszip transient dependency from 3.7.1 to 3.10.1.

Cloud Firestore

  • Prevent spurious "Backend didn't respond within 10 seconds" errors when network is in fact responding, but slowly. See GitHub PR #8145.
  • Update protobufjs transitive dependency from 6.11.3 to 7.2.6.
  • Return to using xmlhttprequest for bidi-streams, as fetch streams seem to be having connection issues.
  • Reduce code bundle size by 6.5 kB in applications that only use memory persistence (the default persistence mode). This bundle size regression was accidentally introduced in version 10.7.2.

Version 10.11.0 - April 11, 2024

  • FirebaseServerApp is no longer JSON serializable.
  • Upgraded undici version to 5.28.4 due to the low severity security issue CVE-2024-30260.

  • Upgrade undici version to 5.28.3 due to the low severity security issue CVE-2024-24758.

Version 10.8.0 - February 1, 2024

  • Fixed to catch transaction.done errors in readHeartbeatsFromIndexedDB and log them as a warning, because platform logging errors should never block user app functionality.

Authentication

  • Added a firebase/auth/web-extension entry point for web extension developers. This entry point does not include any code that loads remote scripts, which are disallowed under Manifest V3. In extensions, this entry point should replace firebase/auth completely, and developers should not try to use both in the same app. See GitHub issue #7617.

Analytics

  • Added two new consent options to the ConsentSettings interface: ad_personalization and ad_user_data.

Realtime Database

  • Support special characters in query paths sent to getCountFromServer(...), getCount(...) (lite API), and getDocs(...) (lite API).

Version 10.7.1 - December 5, 2023

App Check

  • Prevent App Check from logging "uncaught" cancelled promises. The cancelled promises are part of App Check's expected behavior, and their cancellation wasn't intended to produce errors or warnings. See GitHub issue #7805.

Authentication

  • Added protections when enumerating an empty list in Auth's reading of IndexedDB results, as this causes errors in some macOS and iOS browser runtimes. See GitHub issue #7825.

Version 10.7.0 - November 27, 2023

  • Replaced node-fetch dependency with the latest version of undici in Node.js SDK builds for Auth, Firestore, Cloud Functions, and Storage. See GitHub issue #7280.

Authentication

  • Exposed INVALID_LOGIN_CREDENTIALS as auth/invalid-credential error and updated docs for various Auth SDK methods.

Cloud Firestore

  • Introduced fixes for high memory usage of Firestore in browsers. See GitHub issue #6118.

Version 10.6.0 - November 9, 2023

  • Provide a more robust check to cover more cases of empty heartbeat data.

Authentication

  • Add Sign in with Apple token revocation support.

Cloud Firestore

Version 10.5.2 - October 26, 2023

Authentication

  • Added the TotpMultiFactorGenerator and TotpSecret exports that were missing from the React Native entry point.

Cloud Firestore

  • Rolled back the use of useFetchStreams, which had led to hanging queries. This bug was introduced in 10.4.0.

Version 10.5.1 - October 26, 2023

Authentication

Cloud Firestore

  • Clarified API documentation around getFirestore() and initializeFirestore() functions.

Version 10.5.0 - October 12, 2023

Version 10.4.0 - September 14, 2023

Cloud Firestore

  • Added enablePersistentCacheIndexAutoCreation() function to enable automatic creation of local cache query indexes, which can improve performance of local query execution.

  • Fixed an issue where Cloud Firestore was incorrectly using XHR instead of fetch for streaming response.

  • Updated dependency grpc-js from version ~1.8.17 to ~1.9.0.

Version 10.3.1 - August 31, 2023

Cloud Firestore

  • An internal refactor related to client-side index creation.

Version 10.3.0 - August 22, 2023

Authentication

  • Fixed a regression in version 10.0.0 caused by adding a hard dependency on @react-native-async-storage/async-storage as a convenience for React Native developers. This caused unnecessary warnings during npm or Yarn install for non-React Native users, and in some cases, React version conflicts.

    10.3.0 will break React Native users who have converted to using getAuth() to initialize Authentication. React Native users who want persistent auth state must now explicitly import @react-native-async-storage/async-storage and provide it to initializeAuth() as an option like so:

    import { initializeAuth, getReactNativePersistence } from 'firebase/auth';
import ReactNativeAsyncStorage from '@react-native-async-storage/async-storage';
const auth = initializeAuth(app, {
  persistence: getReactNativePersistence(ReactNativeAsyncStorage)
});
// getAuth() can be used any time after initialization

    See Github issue #7522.

Cloud Firestore

Version 10.2.0 - August 17, 2023

Authentication

  • Added a validatePassword method for validating passwords against the password policy configured for the project or a tenant. This method returns a status object that can be used to display the requirements of the password policy and whether each one was met.

  • Fixed a bug in the onAuthStateChanged canceller. See Github issue #7383.

  • The SDK now raises an error if initializeRecaptchaConfig is called in a Node.js environment.

Cloud Firestore

  • Updated @grpc/proto-loader from v0.6.13 to v0.7.8. This addresses a vulnerability in an older version of the transitive dependency protobufjs.

Version 10.1.0 - July 20, 2023

Authentication

  • Implemented authStateReady(), which returns a promise that resolves immediately when the initial auth state is settled and currentUser is available. When the promise is resolved, currentUser might be a valid user or null if there is no user signed in currently.

  • Unpinned the version of the dependency @react-native-async-storage/async-storage so that React Native users have more control over which version of it they use. See Github issue #7448.

Cloud Firestore

  • Updated the grpc dependency to the latest version. See Github PR #7452.

  • Fixed issue where count and firestore-lite API queries did not work with named databases. See Github PR #7440.

Version 10.0.0 - July 6, 2023

The Firebase JavaScript SDK v10.0.0 has a number of breaking changes related to the React Native bundle for Authentication, as well as typings changes across several products.

Authentication

  • Removed explicit firebase/auth/react-native entry point. The React Native bundle should be automatically picked up by React Native build tools which recognize the react-native fields in package.json (at the top level and in exports). See Github PR #7138.

  • Changed getAuth() in the React Native bundle to default to importing AsyncStorage from @react-native-async-storage/async-storage instead of from the react-native core package (which has recently removed it). See Github PR #7128.

  • Changed the type of ParsedToken values from any to unknown.

  • Reordered RecaptchaVerifier parameters so auth is the first parameter.

Realtime Database

  • Updated type of action parameter for DataSnapshot#forEach.

Cloud Firestore

  • Fixed updateDoc() typing issue by adding a second type parameter to FirestoreDataConverter. See Github PR #7310.

  • Changed UpdateData to expand support for types with index signatures. See Github PR #7318.

  • Fixed an issue where localCache was not copied as part of Settings.

  • Fixed some incorrectly generated source maps for the following bundles: index.esm2017.js, index.cjs.js, index.node.mjs, and index.browser.esm2017.js (lite SDK only).

Version 9.23.0 - June 21, 2023

Cloud Firestore

Version 9.22.2 - June 8, 2023

  • Fixed the types path for compat/app to deliver the proper typings to the compat packages. See Github issue #7279.

  • Made the error more helpful when getApp() is called before initializeApp(). See Github PR #7263.

  • Improved error handling for heartbeat read/write errors. See Github issue #6871.

Authentication

Cloud Firestore

  • Enabled long-polling networking mode auto detection by default. It can be explicitly disabled by setting FirestoreSettings.experimentalForceLongPolling to false. See Github PR #7236.

  • Added the ability to configure the long-polling GET request timeout using the new experimentalLongPollingOptions.timeoutSeconds setting. See Github PR #7176.

Version 9.21.0 - April 27, 2023

Analytics

  • Added method getGoogleAnalyticsClientId() to retrieve an unique identifier for a web client. This allows users to log purchase and other events from their backends using Google Analytics 4 Measurement Protocol and to connect them to actions taken on the client within their Firebase web app. getGoogleAnalyticsClientId() simplifies this event recording process. See Github PR #7158.

App Check

Cloud Firestore

  • Created MemoryLruGarbageCollector a new LRU garbage document collector for memory cache. See Github PR #6943.

  • Optimized the local cache synchronization logic to reduce the number of billed document reads when documents were deleted on the server while the client was not actively listening to the query (e.g. while the client was offline). See Github PR #7229.

  • Fixed stack overflow caused by deeply nested server timestamps. See Github PR #7139.

  • Simplified the internal handling of aggregation results. See Github PR #7170.

  • Updated exports of webchannel-wrapper (a Firestore dependency) to conform to Node ESM standards. See Github PR #7228.

Authentication

  • Increased the popup poller timeout to 8s to support blocking functions for Firefox. See Github PR #7140.

Version 9.20.0 - April 18, 2023

App Check

  • Fixed ReCAPTCHA error handling so that the SDK now catches all ReCAPTCHA errors and then prevents the SDK from making a request to the App Check exchange endpoint, which prevents unnecessary 403 errors and throttling. See Github PR #7203.

Authentication

  • Added App Check support in Authentication.

  • Added ReCAPTCHA Enterprise support.

Cloud Firestore

  • Fixed a bug that sometimes prevented aggregations from being run when multi-tab persistence was enabled.

Version 9.19.1 - March 31, 2023

Authentication

  • Fixed typings for TotpMultiFactorGenerator. This fixes a reversion in 9.19.0. See Github issue #7174.

Version 9.19.0 - March 30, 2023

Authentication

  • Support TOTP as a multi-factor option in Firebase Auth/GCIP. See Github PR #7146.

  • Modify _fail(...) to use AuthErrorCode.NETWORK_REQUEST_FAILED and accept an error message. See Github PR #7125.

Analytics

  • Use the Trusted Types API when composing the gtag URL. See Github PR #7155.

Cloud Firestore

  • Introduced additional configurations for Firestore SDK Cache. See Github PR #7015.

  • Verify DOMException exists before referencing it. See Github PR #7130.

Version 9.18.0 - March 16, 2023

Authentication

  • Fixed a bug where updateCurrentUser set user metadata to undefined. See Github issue #7066.

Cloud Firestore

  • Added support for disjunctions in OR queries. See Github PR #7053.

  • Improved debug logging of GrpcConnection and WebChannelConnection. See Github PR #7076.

  • Updated check for an IndexedDB bug in Safari to include navigator.userAgent when determining whether to trigger a workaround. This is helpful for Cordova apps that lack appVersion in their webview but need to apply the workaround. See Github issue #6509.

Version 9.6.3 - January 13, 2022

Cloud Firestore

  • The Node.js SDK now bundles its internal .proto files into the code instead of reading them from the filesystem at runtime. This prevents errors like no such file or directory in certain types of deployments. See Github issue #5823.

Cloud Messaging

  • Fixed a bug where the fcmMessageId field in the message payload was incorrectly defined as fcm_message_id.

  • Add a CJS bundle for messaging/sw. This enables some SSR frameworks to run their Node.js pipelines without erroring. See Github issue #5854.

  • Fixed a bug that caused crashes in Cloud Storage, Cloud Functions for Firebase Client SDK, and Realtime Database when using the all-in-one firebase import, as in import firebase from 'firebase'.

Realtime Database

  • Fixed an issue that could cause once() to fire more than once if the value was modified inside its callback.

Version 8.6.0 - May 11, 2021

App Check

  • Published the App Check package.

Realtime Database

  • Fixed typings for useEmulator.

Cloud Firestore

  • useEmulator now accepts an optional mockUserToken.

Version 8.4.3 - April 29, 2021

Realtime Database

  • Fixed an issue that prevented the SDK from firing cancel events for Firebase Security Rules violations. See GitHub issue #4818.

  • Fixes a regression introduced in version 8.4.1 that broke useEmulator(). See GitHub issue #4811.

Version 8.4.2 - April 23, 2021

  • Fixed outdated peerDependencies.

Cloud Firestore

  • Fixed an issue where errors from grpc are thrown directly to user code. Now they are wrapped in FirestoreError.

  • Fixed an issue where an empty X-Firebase-GMPID header is sent in the request when appId is not available. See GitHub issue #4795.

Cloud Storage

  • Fixed the infinite recursion caused by the FirebaseStorageError message getter.

Version 8.4.1 - April 13, 2021

Realtime Database

  • Fixed a build issue that caused SDK breakage.

Version 8.4.0 - April 12, 2021

Cloud Storage

  • Added a storage().useEmulator() method to enable emulator mode for storage. This allows you to set a storage emulator host and port.

Cloud Firestore

  • Fixed a bug where decimal inputs to Timestamp.fromMillis() were calculated incorrectly due to floating point precision loss.

Version 8.3.3 - April 08, 2021

  • This update only includes internal refactoring.

Version 8.3.2 - March 31, 2021

  • This update includes internal refactoring.

Version 8.3.1 - March 18, 2021

  • Fixed a bug caused by an outdated version of the tslib dependency. See GitHub issue #4633.

Version 8.3.0 - March 10, 2021

Cloud Firestore

  • Added support to remove the FirestoreDataConverter on a Firestore reference by calling withConverter(null)

Version 8.2.10 - March 4, 2021

Analytics

  • Fixed typings for analytics().logEvent() so that the eventParams argument is correctly typed as optional.

Version 8.2.9 - February 19, 2021

  • API update for an internal package. There is no change in the public API.

Version 8.2.8 - February 18, 2021

Analytics

  • Fixed a behavior causing gtag.js to be downloaded twice on Firebase Analytics initialization. See GitHub issue #2628.

Version 8.2.7 - February 11, 2021

Realtime Database

  • Fixed an issue with Query.get() where Query filters were not applied to data in some cases.

  • Added the missing type definitions for startAfter() and endBefore().

Cloud Firestore

  • Fixed a bug where local cache inconsistencies were unnecessarily being resolved.

  • Fixed the path to the react native memory-only build.

Version 8.2.6 - February 04, 2021

Authentication

Realtime Database

  • Fixed an issue with startAfter/endBefore when used in orderByKey queries.

Cloud Firestore

  • Correctly handle ignoreUndefinedProperties in set({ merge: true }). Previously this would behave as if the undefined value were FieldValue.delete(), which wasn't intended.

Version 8.2.5 - January 28, 2021

Realtime Database

  • When issued for queries that are being listened to, get() calls no longer send backend requests.

Cloud Firestore

  • Classes like DocumentReference and Query can now be serialized to JSON. See GitHub issue #4258.

Version 8.2.4 - January 21, 2021

Realtime Database

  • Added startAfter and endBefore filters for paginating Realtime Database queries.

Authentication

  • Added the useEmulator() function and emulatorConfig to the firebase package externs.

Cloud Firestore

  • Fixed an error that caused FirestoreDataConverter.fromFirestore() to be called with an incorrect QueryDocumentSnapshot object. See GitHub issue #4278

Version 8.2.3 - January 14, 2021

Realtime Database

  • Fixed an issue that caused refFromUrl() to reject production database URLs when useEmulator() was used.

Version 8.2.2 - January 7, 2021

Realtime Database

  • Fixed an issue with multiple database instances when using the Realtime Database emulator. See GitHub issue #3681

Cloud Firestore

  • Updated an outdated error message to include != and not-in as inequality operators. See GitHub issue #4253

  • Fixed an issue in the Transaction API that caused the SDK to return invalid DocumentReference objects through DocumentSnapshot.data() calls. See GitHub issue #4226

Version 8.2.1 - December 17, 2020

Authentication

  • Updated auth token logic to rely on device clock time instead of server time. This fixes an issue seen when a device's clock is skewed by a lot: see GitHub issue #3222

Cloud Firestore

  • Fixed an issue that prevented the SDK from automatically retrieving custom claims for a User. See GitHub issue #4175

Version 8.2.0 - December 11, 2020

Authentication

  • Added an option to hide the banner in Auth when using the emulator.

Cloud Firestore

  • Released Firestore Bundles (pre-packaged Firestore data). For NPM users, this can be enabled via an additional import: firebase/firestore/bundle. For CDN usage, it is enabled by default.

  • A write to a document that contains FieldValue transforms is no longer split up into two separate operations. This reduces the number of writes the backend performs and allows each WriteBatch to hold 500 writes regardless of how many FieldValue transformations are attached.

Performance Monitoring

  • Changed to dispatch no more than 1000 collected performance events for each network request. Events over the cap will be queued and sent with the next dispatch.

Version 8.1.2 - December 3, 2020

Authentication

  • Fixed an issue with IndexedDB retry logic causing uncaught errors.

Cloud Firestore

  • Fixed a bug that prevented usage of FieldPath objects with multiple special characters.

  • Fixes an issue that returned invalid DocumentReference instances from QuerySnapshot objects. See GitHub issue #4125

Testing SDK

  • Fixed assertFails not recognizing permission-denied errors from Realtime Database.

Version 8.1.1 - November 19, 2020

Realtime Database

  • Added the missing type definition for Query.get().

Cloud Firestore

  • Fixed an issue that prevented experimentalAutoDetectLongPolling from working correctly.

Version 8.1.0 - November 19, 2020

Realtime Database

  • We have identified an issue in the newly added Query.get() API. This causes data to be returned which doesn't match the Query filters. We are working on providing a fix.
  • Added a database query get method that returns server results when connected.

Cloud Firestore

  • Fixed a regression introduced in v8.0.2 that returned invalid values for DocumentChange.newIndex. See GitHub issue #4071

Version 8.0.2 - November 12, 2020

Authentication

  • The SDK now retries IndexedDB errors a fixed number of times to handle connection issues in mobile WebKit. Fixes GitHub issue #1926.

Cloud Firestore

  • Fixed an issue that caused DocumentReference objects in DocumentSnapshot instances to be returned with the custom converter of the original DocumentReference.

Version 8.0.1 - November 5, 2020

Cloud Messaging

  • Fixed an issue where a silent-push warning was displayed along with the message shown by ServiceWorkerRegistration.showNotification. Added a timeout for the onBackgroundMessage hook so that silent-push warnings won't show if ServiceWorkerRegistration.showNotification is called inside the hook within 1 second. See GitHub issue #3725.

Testing SDK

  • Added a withFunctionTriggersDisabled method which runs a user-provided setup function with emulated Cloud Functions triggers disabled. This can be used to import data into the Realtime Database or Cloud Firestore emulators without triggering locally emulated functions. This method only works with Firebase CLI version 8.13.0 or higher.

Version 8.0.0 - October 26, 2020

  • Breaking change: browser fields in package.json files now point to ESM bundles instead of CJS bundles. Users who are using ESM imports must now use the default import instead of a namespace import.

    Before 8.0.0

    import * as firebase from 'firebase/app'

    After 8.0.0

    import firebase from 'firebase/app'

    Code that uses require('firebase/app') or require('firebase') will still work, but in order to get proper typings (for code completion, for example) users should change these require calls to require('firebase/app').default or require('firebase').default. This is because the SDK now uses typings for the ESM bundle, and the different bundles share one typings file.

Cloud Firestore

  • Removed the undocumented Firestore.logLevel property.

  • Breaking change: Removed deprecated experimentalTabSynchronization settings. To enable multi-tab synchronization, use synchronizeTabs instead.

  • This release removes runtime type validations that are covered by TypeScript. Developers can use our TypeScript types to validate API usage.

  • Breaking change: Removed the timestampsInSnapshots option from FirestoreSettings. Now, Cloud Firestore always returns Timestamp values for all timestamp values.

  • Added a useEmulator(host, port) method to Cloud Firestore.

  • Removed excess validation of null and NaN values in query filters. This more closely aligns the SDK with the Cloud Firestore backend, which has always accepted null and NaN for all operators.

Cloud Storage

  • This release removes runtime type validations that are covered by TypeScript. Developers can use our TypeScript types to validate API usage.

Realtime Database

  • Added a useEmulator(host, port) method to Realtime Database.

Cloud Functions for Firebase Client SDK

  • Added a useEmulator(host, port) method to the Cloud Functions for Firebase Client SDK.

Version 7.24.0 - October 15, 2020

Authentication

  • Added the ability to configure the SDK to communicate with the Firebase Emulator.

Cloud Firestore

  • Added a new experimentalAutoDetectLongPolling to FirestoreSettings. When enabled, the SDK's underlying transport layer automatically detects if long-polling should be used. This is very similar to experimentalForceLongPolling, but only uses long-polling if required.

  • Fixed a potential issue in our internal queue that could have allowed API calls to be executed out of order.

Testing SDK

  • Changed to not delete the uid property from user auth object in initializeTestApp(). See GitHub issue #3920.

  • Fixed the typing for custom claims.

Version 7.23.0 - October 8, 2020

Analytics

  • The SDK now warns instead of throwing an error if it detects a browser environment where Analytics does not work.

Cloud Firestore

  • The SDK now includes more information in the error message for failed IndexedDB transactions.

Performance Monitoring

  • Moved the loggingEnabled check to wait until performance initialization finishes, which prevents the SDK from dropping custom traces right after getting the performance object.
  • Throws an exception when startTime or duration is not a positive value in the trace.record() API.

Testing SDK

  • Added stronger types to the options.auth option for initializeTestApp().

Version 7.22.1 - October 5, 2020

Cloud Functions for Firebase Client SDK

  • Fixed a bug introduced in 7.21.1 that causes callable functions to throw an error in some environments.

Version 7.22.0 - October 1, 2020

Cloud Functions for Firebase Client SDK

  • Users can now set a custom domain for callable functions.

Version 7.21.1 - September 24, 2020

Cloud Firestore

  • Fixed an issue that prevented waitForPendingWrites() from resolving in background tabs when multi-tab is used. See GitHub issue #3816.

  • Fixed a "Comparison with -0" lint warning for customers that build from source. See GitHub issue #3814.

Authentication

  • Fixed an encoding issue in the Authentication CDN script for environments that require UTF-8, for example, Chrome extensions. See GitHub issue #414.

Version 7.21.0 - September 17, 2020

Cloud Firestore

  • Added not-in and != query operators for use with .where().
    • not-in finds documents where a specified field’s value is not in a specified array.
    • != finds documents where a specified field's value does not equal the specified value. Neither query operator will match documents where the specified field is not present.
  • The SDK now uses FirestoreError instead of Error in onSnapshot*() error callbacks.
  • Fixed a bug where CollectionReference.add() called FirestoreDataConverter.toFirestore() twice instead of once. See GitHub issue #3742

Realtime Database

  • Fixed detection of Admin SDK context.

Testing SDK

  • Fixed a bug preventing users from testing Realtime Database with both the Admin SDK and the client JS SDK.

Version 7.20.0 - September 10, 2020

Analytics

  • For apps using v7.20.0 and later, Firebase dynamically fetches the measurementId when your app initializes Analytics. Having this ID in your Firebase config object is optional, but it does serve as a fallback in the rare case that the dynamic fetch fails. Learn more about this field in the Analytics getting started page.

Realtime Database

  • The SDK can now infer a default database URL if none is provided in the config.

Cloud Firestore

  • Fixed a bug where, if a user change happened while the network connection was disabled, the client did not raise snapshots from cache.

Cloud Messaging

  • The SDK no longer opens non-origin links, fixing a potential security issue.

Version 7.19.1 - August 27, 2020

Cloud Firestore

  • Added merge option to firestore.settings(), which merges the provided settings with settings from a previous call. This addresses GitHub issue #3354.

Testing SDK

Version 7.19.0 - August 20, 2020

Testing SDK

  • Released @firebase/rules-unit-testing to replace the @firebase/testing package. The new package is API compatible but has the following breaking behavior changes:
    • assertFails() now fails only on PERMISSION DENIED errors, not any error.
    • initializeAdminApp() now relies on firebase-admin rather than imitating the Admin SDK.

Performance Monitoring

  • Adds a check to silently prevent Performance Monitoring from initializing if the required indexedDB.open() API is not available in the environment.

Cloud Firestore

  • terminate() can now be retried if it fails with an IndexedDB exception. See GitHub issue #2755.

  • Enabled fallback for auto-generated identifiers in environments that support crypto but not crypto.getRandomValues. See GitHub PR #3487.

Version 7.18.0 - August 13, 2020

Cloud Messaging

  • Added onBackgroundMessage, which is called regardless of whether or not a notification is displayed.

  • getToken now accepts an options object that includes an optional vapid key and an optional service worker registration.

  • Deprecated setBackgroundMessageHandler. Use the new API onBackgroundMessage instead.

  • Deprecated useVapidKey and useServiceWorker. Use getToken to set these values instead.

  • Deprecated onTokenRefresh which is a no-op API currently.

Cloud Firestore

  • The SDK no longer crashes with the error "The database connection is closing". Instead, the individual operations that cause this error may be rejected. Addresses GitHub issue #3495.

  • Fixed a bug that caused slow retries for IndexedDB operations even when a webpage re-entered the foreground.

Analytics

  • analytics.isSupported() now returns Promise<false> for extension environments.

Version 7.17.2 - August 6, 2020

Realtime Database

  • Added interface Database which is implemented by FirebaseDatabase. This allows consumer SDKs (such as the Firebase Admin SDK) to export Realtime Database types as an interface.

Cloud Firestore

  • Upgraded to the latest version of Google Closure Library and Compiler. Developers will not need to make any changes to their code to handle this change.

Version 7.17.1 - July 24, 2020

Analytics

  • Added an omitted dependency update that caused Analytics to error on initialization. Addresses GitHub issue #3469.

Version 7.17.0 - July 23, 2020

Analytics

  • Added an analytics.isSupported() method which returns true if the current browser context supports Analytics. This can used in a conditional to prevent initialization of Analytics in environments that don't support it. This check also automatically runs when Analytics is initialized (firebase.analytics()) and if it finds an unsupported environment, throws an error advising developers to use isSupported(). Addresses GitHub issue #2393.

Cloud Storage

  • Error messages for backend errors now include the backend's response message.

Version 7.16.1 - July 16, 2020

Cloud Firestore

  • The SDK no longer crashes if an IndexedDB failure occurs when unsubscribing from a Query.

  • Removed a delay that prevented Firestore from immediately reestablishing a network connection if a connectivity change occurred while the app was in the background.

Realtime Database

  • Instead of using production auth, the SDK will use test credentials to connect to the Emulator when Realtime Database is used via the Firebase Admin SDK. Fixes GitHub issue #3144.

Cloud Storage

  • Updated the TypeScript types for all APIs using Observers to allow callback omission. Fixes GitHub issue #3158.

Authentication

  • Added the browser field in package.json.

Version 7.16.0 - July 09, 2020

Cloud Firestore

  • Added support for set() with merge options when using FirestoreDataConverter.

  • Re-added the React Native bundle, which allows Cloud Firestore to be used without btoa/atob polyfills.

  • Removed internal wrapper around our public API that was meant to prevent incorrect SDK usage for JavaScript users, but caused the SDK to stop working in IE11. See GitHub issue #3305.

FCM

  • Fixed an issue where we tried to update the token for every getToken() call because we don't save the updated token in the IndexedDB.

  • Fixed an RxJS incompatibility issue by adding support for onMessage so the internal callback can work with RxJS's Subscriber. See GitHub issue #3142.

Cloud Functions for Firebase Client SDK

  • Clear timeout after a successful response or after the request is canceled. Fixes GitHub issue #3289.

Version 7.15.5 - June 25, 2020

Cloud Firestore

  • Fixed a bug that sometimes caused Cloud Firestore operations to fail during an auth token change. See GitHub issue #3179

Version 7.15.4 - June 20, 2020

Cloud Firestore

  • Removed the React Native entry point due to an issue in our internal library. For Cloud Firestore in React Native, use the browser build and add necessary polyfills. See GitHub issue #2667

Version 7.15.3 - June 19, 2020

Cloud Firestore

  • Fixed an issue that prevented Cloud Firestore from working in React Native. See GitHub issue #2667

Version 7.15.2 - June 18, 2020

Realtime Database

  • Added an internal HTTP header to the WebSocket connection.

Cloud Firestore

  • Updated grpc-js to version ^1.0.0.

Version 7.15.1 - June 11, 2020

Cloud Firestore

  • Fixed an issue that prevented the client from connecting to the backend immediately after a user signed in. See GitHub issue #2923.

  • Fixed a regression introduced in PR #3048 that changed the context.path variable from Path|null to undefined|null. See GitHub issue #3172.

Version 7.15.0 - June 04, 2020

Cloud Firestore

  • Added an experimentalForceOwningTab setting that can be used to enable persistence in environments without localStorage, which allows persistence to be used in Web Workers. See GitHub issue #983.

  • All known failure cases for IndexedDB-related crashes have now been addressed. Instead of crashing the client, IndexedDB failures result in rejected operations (for example, rejected Writes or errored Query listeners). If these rejections surface in your app, you can retry these operations when IndexedDB access is restored. IndexedDB failures that occur due to background work are automatically retried.

    If you continue to see IndexedDB-related crashes, please provide feedback GitHub issue #2755.

Version 7.14.6 - May 29, 2020

Cloud Firestore

  • Fixed an issue that could cause Cloud Firestore to temporarily go offline when a Window visibility event occurred.

  • Added support for calling FirebaseFirestore.settings with { ignoreUndefinedProperties: true }. When this parameter is set, Cloud Firestore ignores undefined properties inside objects rather than rejecting the API call.

Version 7.14.5 - May 21, 2020

Realtime Database

  • Fixed a Realtime Database URL parsing bug to support domains with more than 3 components.

Version 7.14.4 - May 14, 2020

Cloud Firestore

  • Fixed a regression introduced in v7.14.2 that incorrectly applied a FieldValue.increment in combination with set({...}, {merge: true}).

Version 7.14.3 - May 07, 2020

Cloud Firestore

  • Cloud Firestore now rejects onSnapshot() listeners if they cannot be registered in IndexedDB. Previously, these errors crashed the client.

Version 7.14.2 - April 23, 2020

Cloud Firestore

  • Firestore now rejects write operations if they cannot be persisted in IndexedDB. Previously, these errors crashed the client.

  • Fixed a source of IndexedDB-related crashes for tabs that receive multi-tab notifications while the file system is locked.

FCM

  • Changed to compare hostname instead of the entire URL to decide if there is a matching window client. See GitHub issue #390.

Version 7.14.1 - April 16, 2020

Cloud Storage

  • Fixed an issue that occurred when users tried to retrieve data from multiple Cloud Storage instances.

Authentication

  • Fixed a bug that occurred when users set persistence to LOCAL in a worker environment. See GitHub issue #2903.

Version 7.14.0 - April 9, 2020

Cloud Firestore

  • Replaced grpc with @grpc/grpc-js in the Node.js builds. As a result, the minimum supported NodeJS version is now 8.13.0.

Realtime Database

  • Added ServerValue.increment() to support atomic field value increments without transactions.

Performance Monitoring

  • Updated internal performance event transport mechanism.

Version 7.13.2 - April 2, 2020

Cloud Firestore

  • Fixed a regression introduced by a crypto change in 7.13.0 that breaks Firestore in IE 11. See GitHub issue #2827.

  • Fixed an issue that causes excessive reads in large changesets over slow connections. See GitHub issue #2683.

  • Fixed an issue causing WriteBatch.commit() to resolve one loop later than .set and .update. See GitHub issue #2822.

FCM

  • Fixed an issue introduced in 7.7.0, when FCM switched to provide base64-encoded VAPID keys to PushManager for push subscription. For backward compatibility, the SDK has switched back to using VAPID keys in type ArrayBuffer. See Github issue #2712.

Version 7.13.1 - March 27, 2020

Cloud Firestore

  • Removed a dangling comma in package.json.

Version 7.13.0 - March 26, 2020

Cloud Firestore

  • Added a memory-only firestore build. Instead of persisting data in the IndexedDB, it keeps it in memory. This build is about 14% smaller than the full featured build because it doesn't have IndexedDB related code. If you don't care about persisting data across sessions, or your code runs in environments that don't support IndexedDB, use this build to reduce your application size. It is available under a special import path. You can import it this way: 

    import * as firebase from 'firebase/app';
import 'firebase/firestore/memory';
    


    // Don't change the format for any other products.
import 'firebase/auth';
// etc.

    Or if using the CDN: 

    <script src="https://www.gstatic.com/firebasejs/7.13.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/7.13.0/firebase-firestore.memory.js"></script>
<!-- Don't change the format for any other products. -->
<script src="https://www.gstatic.com/firebasejs/7.13.0/firebase-auth.js"></script>
<!-- etc. -->

Analytics

  • Added convenient enums and function overloads to support enhanced ecommerce events.

Version 7.12.0 - March 19, 2020

  • Added two methods for logging:
    • firebase.setLogLevel(), which sets the level above which Firebase log messages will be shown.
    • firebase.onLog(), which adds a user-specified callback run on each log event. The callback has access to log level, message, and name of the package (e.g. "@firebase/firestore") that generated the log message.

Cloud Firestore

  • Fixed an issue where the number value -0.0 would lose its sign when stored in Cloud Firestore.

Version 7.11.0 - March 12, 2020

Authentication

Version 7.10.0 - March 5, 2020

Cloud Firestore

  • Implemented Timestamp.valueOf() so that Timestamp objects can be compared for relative ordering using the JavaScript arithmetic comparison operators. Fixes GitHub issue #2632.

Version 7.9.3 - February 28, 2020

Cloud Storage

  • Fixed an issue introduced in 7.9.2 where Cloud Storage could throw a CORS error (GitHub issue).

Version 7.9.2 - February 27, 2020

Cloud Firestore

  • Fixed an issue where OnlineState value was mangled and was not being parsed correctly.

Version 7.9.1 - February 21, 2020

Cloud Firestore

  • Fixed an issue introduced in 7.9.0 where minified Cloud Firestore Node and CJS bundles do not work.

Version 7.9.0 - February 20, 2020

Cloud Firestore

  • The minified version of the Cloud Firestore library, added as an experimental option in 7.8.0, is now the default Cloud Firestore bundle. The steps listed in the 7.8.0 release notes are no longer necessary to get the minified bundle. This minification currently reduces the total bundle size by approximately 15% as of this build.

  • Fixed an issue where auth credentials were not respected in Cordova environments. See Github issue #2626.

  • Fixed a performance regression introduced by the addition of Query.limitToLast(n: number) in Firestore 1.7.0 (Firebase 7.3.0). See Github issue #2620.

FCM

  • Fix an issue where service workers do not reliably update after upgrading to a new version of Firebase. See Github issue #2590.

Version 7.8.2 - February 13, 2020

Cloud Firestore

  • Fixed an issue where CollectionReference.add() would reject custom types when using withConverter(). Github issue #2606.

Version 7.8.1 - February 6, 2020

Cloud Firestore

  • Fix a bug causing intermittent errors when the same app is open in multiple tabs. Addresses Github issue #2555.

Version 7.8.0 - January 30, 2020

Cloud Firestore

  • Experimental: Added an alternative minified import for the firestore package. Users who want to try this experimental import can do it this way:

    import * as firebase from 'firebase/app';
import '@firebase/firestore/dist/index.cjs.min';

// Don't change the format for any other products.
import 'firebase/auth';
// etc.

    Or if using the CDN: 

    <script src="https://www.gstatic.com/firebasejs/7.8.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/7.8.0/firebase-firestore.min.js"></script>
<!-- Don't change the format for any other products. -->
<script src="https://www.gstatic.com/firebasejs/7.8.0/firebase-auth.js"></script>
<!-- etc. -->

Version 7.7.0 - January 16, 2020

Cloud Firestore

  • Fixed an issue where auth credentials were not respected in some Firefox or Chrome extensions. See Github issue #1491.

  • Firestore previously required that every document read in a transaction must also be written. This requirement has been removed, and you can now read a document in a transaction without writing to it.

Performance Monitoring

  • Updated internal transport protocol from proto2 to proto3.

Authentication

  • Added missing constructor for SAMLAuthProvider type.

Version 7.6.2 - January 9, 2020

Cloud Functions for Firebase Client SDK

  • Fixed a bug causing notification permissions requests to pop up when using functions.httpsCallable().

Realtime Database

Cloud Firestore

  • Fixed an issue where auth credentials were not respected in certain browser environments (Electron 7, IE11 in trusted zone, UWP apps). Addresses
