Questions & Answers

Q: What is Firestore and how is it different from Firebase's real-time database?

Firestore is a NoSQL database that offers more features and solves limitations found in the real-time database. It allows for nested data querying and an expressive query language, making data organization and searching easier for developers.

Q: How does Firestore handle nested data querying efficiently?

In the real-time database, all nested data had to be loaded together, which hindered proper data organization. However, with Firestore, you can create a tree structure of documents that point to other documents or collections. This allows for memory-friendly queries and easy modeling of data relationships.

Q: What are some advantages of Firestore's query language?

Firestore's query language includes a "where" statement, which can be used for filtering data by equality or range operators. It also allows for the creation of indices based on multiple properties, enabling efficient querying and sorting of data.

Q: How can Angular developers upgrade their applications to use Firestore with Angular Fire 5?

Developers need to uninstall Angular Fire 2, reinstall it with version 5.0 or above, and include the project ID in the Firebase config file. They also need to import the AngularFireStore module and modify the app component to import necessary AngularFire modules and define an interface for the data structure.

Summary & Key Takeaways

• Firebase recently launched Firestore, a NoSQL database that solves limitations of the real-time database. It offers features like nested data querying and an expressive query language.

• Firestore allows for easy organization of data with document trees and supports queries with equality and range operators.

• Upgrading to Angular Fire 5 enables developers to use Firestore in their Angular applications, with changes in installation, project ID requirements, and module additions.
