How to maintain login session across multiple tabs?

Question

I am developing a website and i am having a problem in finding the best solution to maintain user login session. Currently i am using Html5 web storage "session storage" to store whether user is logged in or not. But problem in this is that this only works in a single tab not across multiple tabs of a browser.

What should i use either Cookies or LocalStorage or i should maintain server side session and check every times a page loads on server whether the user is logged in or not ?

What is the best solution? please guide me. I am using Node.js and mongodb in the backend and Angular and jquery in frontend.

First thing you must know is that sessions are made only for server-side not for client side. Second thing, if you want your user to not load everytime, try to save the data in user's cookies also don't think about it will require more time to load on server. Because sessions are only made for security purpose and i guess by storing them on client side you are not using that purpose. Also now major question is how to store them on the server side. Suppose your server goes down now all of your sessions will get deleted. Now to avoid that use some external data store like connect-mongo/connect-redis. redis is faster than mongo but if you want to use only memory store then search for memcached/cookie-sessions/jWT hope this answer helps :)
