How can I implement role management with Firebase Authentication in TypeScript?

To implement role management with Firebase Authentication in TypeScript, you can use custom claims. First, set up Firebase Authentication in your project.

What are custom claims and how do I set them?

Custom claims are key-value pairs that you can add to a user's ID token. You can set them using the Firebase Admin SDK.

Can you show me an example of setting a custom claim?

Sure! Here's a simple example:

import admin from 'firebase-admin';

const setCustomUserClaims = async (uid: string, role: string) => {
  await admin.auth().setCustomUserClaims(uid, { role });
};

This function sets a custom claim for a user.

How do I check a user's role after setting the custom claim?

You can check a user's role by decoding their ID token on the client side. Use the Firebase Auth SDK to get the current user and access their claims.
