Type Alias: UserInformation

UserInformation = object

Defined in: types/index.ts:326

Consolidated user authentication and authorization information.

Remarks​

Authentication Provider: Uses Clerk for user management and JWT generation.

Purpose: Provides a single source of truth for user-related data throughout the application, combining Clerk's user object with custom identifiers and tokens.

Properties:

  • user: Clerk user object with profile data (name, email, avatar). Null when unauthenticated.
  • userIdentifier: Custom unique identifier for the user (typically Clerk user ID or email)
  • userJwt: JSON Web Token for authorizing API requests to the backend

Null Handling: When user is null, the user is not authenticated. However, userIdentifier and userJwt may still contain values from previous sessions (e.g., expired tokens). Always check user for authentication status.

JWT Usage: The userJwt is passed in the Authorization: Bearer <token> header for all authenticated API requests to api.arolariu.ro.

Security: JWT tokens are sensitive. Never log or expose them in client-side code. Tokens are automatically refreshed by Clerk and should be fetched fresh for each request.

Usage Context:

  • User profile components
  • Protected route guards
  • API request authentication
  • Personalized content rendering

Example​

// Authenticated user
const userInfo: UserInformation = {
  user: {
    id: "user_abc123",
    emailAddresses: [{ emailAddress: "user@example.com" }],
    firstName: "John",
    lastName: "Doe"
  },
  userIdentifier: "user_abc123",
  userJwt: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
};

// Unauthenticated user
const anonymousInfo: UserInformation = {
  user: null,
  userIdentifier: "",
  userJwt: ""
};

// Checking authentication
if (userInfo.user) {
  // User is authenticated, proceed with protected action
  await fetchUserInvoices(userInfo.userJwt);
}
