Upgrade your project to Firebase 9: Get the most out of the new features and API changes

When I decided to migrate from Firebase 8 to version 9, I couldn't find all the resources in one place. That's why I decided to write about these changes, so you can easily follow them and keep your code up to date.

Firebase 9 is a significant update that introduces new features and benefits that make it easier for developers to create high-quality apps. This release includes a new modular API that enables tree-shaking, bundle size reduction, and other benefits designed to eliminate unused code.

By adopting the modern JavaScript module format, Firebase 9 enables developers to selectively import only the components they need in their app, rather than importing the entire library.

Depending on your app, tree-shaking with Firebase version 9 can result in up to 80% fewer kilobytes than a comparable app built using version 8.

Upgrading to Firebase 9 may involve some effort to adjust the implementation of companion libraries like @angular/fire, RxFire, and the Firebase Capacitor plugin (if you are building a mobile app).
However, the effort is worth it for the benefits of modularization and reduced app size.

It’s worth mentioning that Firebase version 8 will be frozen at some point in the future, meaning you will not receive any more updates or bug fixes.

While there is a Firebase compat package available to make the migration easier, it is only a temporary fix. I highly recommend upgrading to Firebase 9 to take full advantage of its benefits and keep your app up-to-date.

The effort required to upgrade to Firebase 9 may appear daunting, but it is a necessary step in ensuring that your app is optimized for maximum performance and user experience.

If you want to take full advantage of the latest features and benefits, you must upgrade your Firebase library.
Firebase 9 is a must-have for any developer who wants to build high-quality apps that perform well and provide the best user experience, thanks to its modularized approach, reduced app size, and ongoing feature development.

So, what are you holding out for?
Upgrade to Firebase 9 right now!
