Brief

The localSessionCheck function verifies whether a JWT token is valid on the server side without requiring database validation, speeding up the session validation process.

Configuration for localSessionCheck Function

1. Integration

// Fetch headers for verification
const headersList = headers();
const username = headersList.get('userName');
const jwtToken = headersList.get('token');
 
// Verify the session
const response = await localSessionCheck(username, jwtToken, userAgent);
// userAgent = Name of the user's agent (e.g., browser, device, etc.)

2. Error Responses

3. Success Response

When you receive a 202 response, it means the session exists. The response will include the following details:

{
    userName: priyalraj, 
    message: "Session exists.",
    status: 202
};

Final Step: Configuring the Server Session Check Function

We've covered how to integrate localSessionCheck for quick JWT token validation. Now, it's time to implement the more comprehensive serverSessionCheck, which performs a deeper validation by checking session data against the database. This robust method is ideal for critical API operations that require a higher level of security and thorough session verification.
