Role-based access patterns in NextJS - Mini Project: Build & Apply

Role-based Access Patterns in Next.js

📖 Scenario: You are building a simple Next.js app where users have different roles: admin, editor, and viewer. Each role can access different parts of the app.We want to control which page sections show based on the user's role.

🎯 Goal: Build a Next.js component that shows different messages depending on the user's role using role-based access patterns.

📋 What You'll Learn

Create a user object with a role property

Define a list of allowed roles for a page section

Use conditional rendering to show content only if the user role matches allowed roles

Use Next.js functional components and React hooks

💡 Why This Matters

🌍 Real World

Role-based access control is common in apps where different users have different permissions, like admin dashboards or content editors.

💼 Career

Understanding role-based access patterns is essential for building secure and user-friendly web applications in professional development.

1

Set up the user data

Create a constant called user with an object that has a role property set to the string 'editor'.

NextJS

// Create the user object with role 'editor'
// Your code here

Need a hint?

Think of the user as a person with a job title. Here, the job title is 'editor'.

2

Define allowed roles for a page section

Create a constant called allowedRoles and set it to an array containing the strings 'admin' and 'editor'.

NextJS

const user = { role: 'editor' };
// Define allowedRoles array with 'admin' and 'editor'
// Your code here

Need a hint?

Think of allowedRoles as a guest list for a party. Only 'admin' and 'editor' can enter.

3

Render content conditionally based on role

Create a React functional component called Dashboard. Inside it, return a div that shows the text 'Welcome, editor or admin!' only if user.role is included in allowedRoles. Otherwise, show 'Access denied'.

NextJS

const user = { role: 'editor' };
const allowedRoles = ['admin', 'editor'];

function Dashboard() {
  // Your code here
}

Need a hint?

Use allowedRoles.includes(user.role) to check if the user can see the message.

4

Export the component for use

Add an export statement to export the Dashboard component as the default export.

NextJS

const user = { role: 'editor' };
const allowedRoles = ['admin', 'editor'];

function Dashboard() {
  return (
    
      {allowedRoles.includes(user.role) ? 'Welcome, editor or admin!' : 'Access denied'}
    
  );
}

// Export Dashboard as default
// Your code here

Need a hint?

Use export default Dashboard; to make the component available to other files.
