Well, today we are talking about the concept of "Session Expiry", especially when you use NextAuth.js in your project. Understand in simple and friendly language, so that there is no confusion.
So, first of all let's understand the meaning of "Your session has expired" error. This is anauthentication related error, which appears when the user's login session is terminated. For example, you logged in to a website or app, used it for a while, then left for a while. When I came back, the message appeared on the screen "Session expired, please log in again." Meaning, the permission that previously granted you access to the app has expired, and you will need to re-login to be authenticated again. An example to understand: Imagine, you are in a mall and the security guard gave you a
visitor cardHow does NextAuth mein Session work? Now if we implement NextAuth.js, there are some rules there as well. When a user logs in, NextAuth tracks the user's identity using JWT (JSON Web Tokens)
oris a token that is sent after encoding the user's credentials, and is sent with every request to verify whether the user is valid or not. Session Cookies are stored in the browser, through which the backend knows which user is currently logged in. But, they have an expiry time
, which you can set throughStay Logged In: Some apps give the user the option of "Stay Logged In", which extends the session expiry time. This can be done using token rotation
, where a new token is obtained on every request.
export const authOptions = { session: { strategy: "jwt", // JWT ya session-based approach maxAge: 30 * 60, // 30 minutes ka session timeout }, // baaki authentication providers yahan mention karte hain }
Auto Logout Mechanism: In some cases, due to security reasons, apps intentionally let the session expire early. Like in banking apps, you will notice that if you are inactive for some time, then the session gets logged out. You can also add this to your NextAuth config if you want to maintain high security.
Real-Life Scenario in Apps:and have added some items to your cart. If the session expires, you will login again, but the items in the cart will remain as they are. This is possible because the cart data might have been saved in local storage. But in some sensitive apps like email or banking apps, the user has to force logout when the session expires.
So friends, this is the complete foundation of session expiry, and how NextAuth.js handles it in your project. This concept may seem confusing initially, but when you implement it in the real-world, everything becomes clear gradually.
