What are the best practices for Firestore rules in Vue 3?

When working with Firestore in Vue 3, it's essential to define rules that ensure data security and integrity. Best practices include using granular rules for collections, validating data types, and implementing role-based access control.

Can you give me an example of a Firestore rule?

Sure! Here's a simple example:

service cloud.firestore {
  match /databases/{database}/documents {
    match /users/{userId} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
  }
}

This rule allows users to read and write their own data only.

How can I test these rules?

You can test Firestore rules using the Firebase Emulator Suite. It allows you to simulate requests and see if your rules are working as expected without affecting your production database.

What should I avoid when writing Firestore rules?

Avoid overly broad rules that can expose your data, such as allowing read/write access to all users. Always aim for the principle of least privilege.
