Recommended Method for refreshing session expiration time in Node. js, node. jssession

In Node. js, we usually use the express-session package to use and manage sessions and save the session status between the server and the client browser. So how can we refresh the session expiration time when the user refreshes the current page or clicks the button on the page? Similar to the session Status in ASP. NET, as long as the page remains active for a certain period of time, the session will not expire. The following code implements this function. We Add the following middleware to the Node. js code:

// use this middleware to reset cookie expiration time// when user hit page every timeapp.use(function(req, res, next){  req.session._garbage = Date();  req.session.touch();  next();});

In this way, when a request comes over, the middleware will re-Modify the expiration time of the session to achieve the expected results.

Then, add the session usage in the Code:

app.use(session({    secret: 'test',     resave: false,     saveUninitialized: true,    cookie:{      maxAge: 1000*60*60 // default session expiration is set to 1 hour    },    store: new MemcachedStore({      hosts: ['127.0.0.1:9000'],      prefix: 'test_'    })}));

The above session uses memcached as the session storage method, for how to use memcached can refer to the address on Github https://github.com/balor/connect-memcached

Of course, you can also use other session storage methods, such as memoryStore, redis, and mongoDB.
