$cookies need callback once cookie value is set.

[manishtpatel]

Right now if you set $cookies values then call $http immediately, cookie is not updated in the request. if $cookies returns before saving the cookie in the browser then we need callback to execute code that relies on cookie.

$cookies.myName = 'foo'

// request headers are missing myName cookie update from above line
$http.get('/api/getmystar')

To workaround this issue i have to use setTimeout to wait for some time before i can proceed.

It either need to not set the cookie asynchronously or provide a call back function, call back is not possible with $cookies but $cookieStore atleast should solve this issue.

summary

cookie writes are flushed asynchronously, which makes it hard to predict when the cookie will be picked by other browser apis like XMLHttpRequest used by $http

Maybe what should be addressed is the fact that ngCookies works via polling instead via some other customary Angular pattern ($digest, promises, etc).

When I first saw the way the API was broken down in $cookies and $cookieStore, I thought $cookies was an object that just updated (i.e. did read/write to document.cookie) on $digest, and $cookieStore was essentially a direct wrapper around document.cookie. I.e. $cookieStore.put('key', 'value'); splits and serializes the cookie and adds your value.

When I looked at the actual implementation, I found it really surprising to find that it updates on a poll function. This is a really odd choice.

I think adding a callback to $cookieStore is poor idea, b/c it doesn't really jive w/ Angular well. But I do think this should be addressed (e.g. by returning a promise).

The bug has been closed but $cookies.get() on AngularJS 1.4.7 still doesn't return a promise: how am I supposed to do?
