How can I implement role-based access control in TypeScript?

You can implement role-based access control (RBAC) in TypeScript by defining roles and permissions, then checking these permissions during user actions.

Can you give me a code example?

Sure! Here's a simple example:

interface User {
  id: number;
  role: string;
}

const roles = {
  admin: ['create', 'read', 'update', 'delete'],
  user: ['read'],
};

function hasAccess(user: User, action: string): boolean {
  return roles[user.role]?.includes(action) || false;
}

This checks if a user has permission to perform a specific action based on their role.

What if I want to add more roles later?

You can easily extend the roles object with new roles and their corresponding permissions. Just ensure to update the logic in your access control checks accordingly.
