Google offers Firebase, a service that makes it simple for developers to build, maintain and expand their apps. It makes it easier for developers to create apps more quickly and securely. The Firebase side doesn't require any programming, making it simple to leverage its capabilities more effectively. It offers services to Unity, iOS, Android, and the Web. It offers online storage. The database used for data storage is NoSQL.

Initially, Firebase operated as Envolve and offered an online chat service via API to a variety of websites. It gained popularity as developers began using it to communicate application information, such as the current state of a game, with users in real time rather than only through conversations. As a result, the chat system and Envolve's architecture were split apart. James Tamplin and Andrew Lee, the company's creators, subsequently developed the Envolve architecture to become what Firebase is today in 2012.

You are familiar with Firebase version 8. x and use a modular bundle like Webpack and Rollup for Web packing as well as ongoing Version 9 development.

For apps that require user authentication and Real-time database storage, Firebase provides the ideal tooling. It offers thorough documentation and a wide range of development samples to aid in anyone's learning how to produce excellent apps.

Version 9 of the Firebase Web SDK is compatible with two different categories of libraries:

Modular – A new API development is designed to make tree-shaking (removing unneeded code) easier so that your web app is as quick and minimal as feasible.

Compat – You may update to version 9 without having to change all of your Firebase code at once thanks to a familiar API surface that is fully compatible with version 8 SDK. Compat libraries don't significantly outperform their version 8 counterparts in terms of size or performance.

The Compat library is only a short-term fix at this time; it will be totally eliminated in the release of the following SDK version. Only version 9. x modular-style code must be used in your application; compat code must be eliminated.

Upgrading syntax changes

1). Authentication Functions syntax changes

2). Cloud Firestore Functions syntax changes

3). FireStorage Functions syntax changes

4). getPerformance, trace Functions syntax changes

Syntax changes in AngularFire to version - 7. x with Angular 14

AngularFire package is used for the Angular library for Firebase. In this section, you can get the syntax changes in the updated package.

1). Changes in the app module file

2). @angular/fire/auth syntax changes

3). @angular/fire/storage syntax changes

4). @angular/fire/firestore syntax changes

Note: If you are using Collections then the number of query attributes is in Odd (Ex.  collection(this.afs, `users/${userId}/roles`)  here users/${userId}/roles is in an Odd scenario.

Note: If you are using Documents then the number of query attributes is in Even (Ex.  doc(this.afs, `users/${userId}`)  here users/${userId} is in an Even scenario.

Wrapping up

For backend development, Firebase offers an excellent solution. It offers a live database with a developing user base. You can create and manage the application more effectively with the help of our knowledgeable team at ashutec.
