What are some common usage scenarios for Firestore rules?

Firestore rules are essential for securing your database. Common scenarios include user authentication, data validation, and role-based access control.

Can you give me an example of role-based access control?

Sure! For instance, you can set rules that allow only admins to write to certain collections while allowing all authenticated users to read from them.

How do I implement data validation in Firestore rules?

You can use the validate function in your rules to ensure that the data being written meets specific criteria, like type checks or value ranges.

What happens if I don't set any rules?

If you don't set any rules, your Firestore database will be open to the public, allowing anyone to read and write data, which can lead to security issues.
