Firebase JS SDK version 9 prerelease now available in beta

[Feiyang1]

We are pleased to announce that the version 9 of the Firebase JS SDK is now available in beta! 🎉🔥

Read here on how to upgrade from version 8 to the modular SDK and learn more about version 9 here. You can also access the setup page and API Reference to get started.

Thank you for being a part of the Firebase JS SDK Modularization Alpha program! Your participation was invaluable to us as we built out the new format to give you reduced size of the JavaScript SDK. In particular, we made the following changes based on your feedback:

• Default FirebaseApp. You can call get[Auth/Firestore/etc]() without passing an FirebaseApp instance now. The default app will be used if no instance is passed.
• You are not required to call getAuth() or initializeAuth() before using other products anymore. See this discussion for details.
• ES2017 becomes the default build target.
• Added support for exports field in firebase to support Nodejs 12+.
• Redesigned the Realtime Database API to be consistent with the rest of the SDK.

Please continue to tell us what you like and don’t like on GitHub Discussions. If you encounter any bugs, file them on GitHub Issues.

We look forward to showing you more about this at Google I/O May 18-20. To register for I/O, see here.
