Stay signed in option with cookie-session in expre

问题:

I would like to have a "Stay signed in" option such as the one provided by Gmail. This way, the user can decide if they want to keep the session open upon opening a new browser session after previously closing it.

Looking into the github issues I saw the cookie-session component doesn't provide a way to upate the maxAge property dynamilly.

I'm wondering then if there's any way at all to achieve the "Stay signed in" feature with the cookie-session component.

It seems to me a basic feature for a component which is being downloaded 80K times a month.

// This allows you to set req.session.maxAge to let certain sessions 
// have a different value than the default. 
app.use(function (req, res, next) {
  // here you can see whether they checked the checkbox or not, and change maxAge.
  // the default should be that it expires when the browser is closed
  req.sessionOptions.maxAge = req.session.maxAge || req.sessionOptions.maxAge

  // or you can try to set expires to 1 day from now:
  req.sessionOptions.expires = new Date(Date.now()[phone])
  // or at the end of the session:
  req.sessionOptions.expires = 0
})

If you are using ExpressJS, session module has an option.

Alternatively req.session.cookie.maxAge will return the time remaining in milliseconds, which we may also re-assign a new value to adjust the .expires property appropriately. The following are essentially equivalent
