javascript - Passing data between angularjs and express/node without ajax -



javascript - Passing data between angularjs and express/node without ajax -

i have angularjs app running on node/express backend. i'm using passport user authentication.

when user signs in or signs up, angular controllers communicate express via $http ajax/xhr calls. form info sent, node/express/passport process data, , homecoming json info user's info (i.e. username).

angular uses user info update templates, i.e. {{user.username}}

the problem if user refreshes entire page, angular loses user information. they're still logged in - req.user still contains info - angular doesn't know it.

i'd avoid ajax phone call check if user logged in. that'll http phone call every new visit...

i can pass user info jade template directly, can't updated angular later.

i prefer ngstorage

just check sample illustration given below, come in want text field , refresh browser , see

jsfiddle

since angularjs module makes web storage working in angular way. contains 2 services: $localstorage , $sessionstorage.

differences other implementations

no getter 'n' setter bullshit - right angularjs homepage: "unlike other frameworks, there no need [...] wrap model in accessors methods. plain old javascript here." can enjoy same benefit while achieving info persistence web storage.

sessionstorage - got often-overlooked buddy covered.

cleanly-authored code - written in angular way, well-structured testability in mind.

no cookie fallback - web storage beingness readily available in browsers angularjs officially supports, such fallback largely redundant.
