First things first, find the "Sessions" model in your Xano dashboard. This is where you'll keep all the session-related info like tokens, expiry times, user IDs, and so on.

Next, add a field called "expiry_time" to your "Sessions" model. This will store the timestamp for when the session should expire. Simple, right?

Now, create an API endpoint for user login. When someone logs in, generate a session token and calculate the expiry time. Save both of these in the "Sessions" model along with the user ID. Here's a quick example:

{
  "token": "generated_token_here",
  "expiry_time": "calculated_expiry_time",
  "user_id": "user_id_here"
}

Time to create a middleware function to check if the session is still valid:

1. Grab the session token from the request.
2. Look up the session token in the "Sessions" model.
3. Check if the current time is less than the "expiry_time":

• If it is, go ahead with the request.
• If not, send back an error message.

Create an API endpoint to renew sessions. Here's what you'll do:

1. Validate the session token.
2. If it's good, create a new expiry time and update it in the "Sessions" model.
3. Return the updated session info.

For any endpoint that needs session validation, make sure to use the session check middleware. This will verify the token's validity and expiration before allowing access.

Set up a scheduled task to regularly clean out expired sessions from the "Sessions" model. This keeps your data neat and tidy.

Finally, test everything:

1. Log in and check that the token and expiry time are generated correctly.
2. Try to access protected endpoints with both valid and expired tokens.
3. Renew sessions and make sure the expiry time updates.
4. Confirm that expired sessions are being cleaned up as they should be.
