Validate User Server Side

I want to check if the user has a valid session before fetching data

TypeScript

import { Client, Users } from 'node-appwrite';

export async function GET() {
    const client = new Client()
        .setEndpoint(process.env.NEXT_PUBLIC_APPWRITE_ENDPOINT as string)
        .setProject(process.env.NEXT_PUBLIC_APPWRITE_PROJECT_ID as string)
        .setKey(process.env.APPWRITE_API_KEY as string); // Securely use API key

    const usersAPI = new Users(client);

    try {
        // Fetch the user list from Appwrite
        const usersList = await usersAPI.list();

        // Log the labels for each user
        usersList.users.forEach((user) => {
            console.log(`User: ${user.name}, Labels: `, user.labels);
        });

        const users = usersList.users.map((user) => ({
            name: user.name || 'N/A',
            email: user.email,
            phone: user.phone || 'N/A',
            emailVerification: user.emailVerification, 
            phoneVerification: user.phoneVerification,
            isAdmin: user.labels.includes('admin') // Check if 'admin' label exists in labels array
        }));

        return NextResponse.json({ totalUsers: usersList.total, users });
    } catch (error: any) {
        console.error('Error fetching users:', error);
        return NextResponse.json({ totalUsers: 0, users: [] }, { status: 500 });
    }
}

I am trying to make some middleware that validates a users session and checkf for some custom permissions or the admin label before allowing them to proceed. Using app router in NextJs.

TL;DR

Utilize .setSession to impersonate user instead of using full admin access. Ensure to validate user session before fetching data. The code provided lists users from Appwrite and checks for admin label.
