# Fortune Cookies
2+
JavaScript Applications Exam, 10 September 2015
3+
4+
Implement a SPA application for fortune cookies.
5+
6+
## Application description
7+
8+
The application must provide the following functionality
9+
10+
* **Users** can **Register**, **Login** and **Logout** in the application
11+
* _Users provide `username` and `password`_
12+
* **Logged-in users** can:
13+
* **Share** a new fortune cookie
14+
* Providing `text` and `category`
15+
* **Re-share** an existing fortune cookie
16+
* This can be either:
17+
* A fortune cookie, shared by this user
18+
* A fortune cookie, shared by other user
19+
* **Like** or **dislike** a fortune cookie
20+
* **Get** their hourly fortune cookie
21+
* A random cookie from all shared cookies
22+
* This cookie is changed every hour
23+
* i.e. if the user asks for their fortune cookie at 11:30 and then again at 11:45, their fortune cookie will be the same
24+
* or if the user asks for their fortune cookie at 11:30 and then again at 12:00, the two fortune cookies may be different
25+
* It depends on the total count of fortune cookies
26+
* **All users** (even not logged in) can **see** fortune cookies, that are shared by any user
27+
* **Cookies** can be:
28+
* Sorted by `likes` or `shareDate`
29+
* Filtered by a single `category`
30+
* i.e. show only the fortune cookies in a given `category`
31+
32+
## Application routes
33+
34+
Implement at least the following routes in your app:
35+
36+
* `#/`
37+
* Redirects to `#/home`
38+
* `#/home`
39+
* Shows all fortune cookies
40+
* Available to all users, logged-in or not
41+
* Provides a way to sort the cookies by `likes` or `shareDate`
42+
* Provides a way to filter fortune cookies by `category`
43+
* `#/home?category=CCCC`
44+
* Shows only the fortune cookies in category **CCC**
45+
* `#/my-cookie`
46+
* Shows the current hourly fortune cookie for the logged-in user
47+
48+
49+
