independently manage a session object with browser cookies and timeouts
Independently manage a session object with browser cookies and timeouts. 'Useful when session or user objects are shared between server and client enviornments. To manage cookies alongside the session or expire the session in a browser, use this script in your browser environment and bind it to your session or user objects.
sessionbrowser may be downloaded directly or installed through
$ npm install sessionbrowser
$ git clone$ cd sessionbrowser && npm install
sessionbrowser uses cookie values matching this scheme:
or this scheme:
It operates under the assumption that the number of milliseconds is the time after which the session should expire. If bgndate is not present, Date.now() is used. sessionbrowser timer ends at (bgndate + milliseconds).
With serialised milliseconds, sessionbrowser resumes a prexisting session value on page load or begins a new session.
Assume there is a session object with named-property
token. browsersession should expire alongside token. Token's value is stored as a browser cookie named
The connect method directs sessionbrowser to initialize itself with a value from cookie 'sesstoken'.
// create a sessionthatsessionbrowserObj =;// refresh the session on a token for 20 secondssessionbrowserObj
Tests are not automated but are performed by loading a document in the browser and using the browser console.
To build the test environment, use
npm test from a shell.
$ npm test
file:///), using the test document requires some additional setup.
I use lighttpd and /etc/hosts to make the document available through
sudo apt-get install lighttpd
server.document-root = "/path/to/sessionbrowser/test"
sudo /etc/init.d/lighttpd restart
Then visit the sessionbrowser.com in your browser.
