问题
I am running my client(frondend) app express app in a port 3000 and another admin express app in 8080.
But when I am navigating any pages or refreshing any page in client express app, the session in admin app is lost and redirecting to login.
I am using Express-session npm for admin and frond end is just like a cms frondend, ie no sessions or anything complex. Can any body tell me why is this happening?
回答1:
Cookies for an app running on port 3000 are also sent to an app running on port 8080 (and vice versa).
My guess is that you didn't give each app a unique cookie name, so you might get interference between the session handling of both apps.
So, use a different cookie name for each:
app.use(session({
name : 'frontend.sid', // and, say, 'admin.sid' for the admin app
...
}));

Run in different browsers :
try one of them in different browser like one in chrome and other in mozilla. It is happening due to session clashing over there.
Changing the browser might be a good solution for you.
Want to run in same browser :
Just run one service in normal mode and run other service in incognito mode

Based on the provided information I would suggest that you look over to the way you are initialising express-session. In case that the secure flag is set to true, it would expect a valid HTTPS certificate to be set for localhost, otherwise the session wont be created which can cause redirect problems.
From the docs:
secure: Specifies the boolean value for the Secure Set-Cookie attribute. When truthy, the Secure attribute is set, otherwise it is not. By default, the Secure attribute is not set. Please note that secure: true is a recommended option. However, it requires an https-enabled website, i.e., HTTPS is necessary for secure cookies. If secure is set, and you access your site over HTTP, the cookie will not be set.
