A simple app with city search and city weather display functionalities. Utilising free weather api available at http://openweathermap.org.

• Due to the fact that the openweather api is sometimes very slow, the limit of the LRU has been set to 5 entries. It is configurable in the service implementation.
• The LRU is implemented as a service. It is a long-living singleton object that can be injected in places where it is needed (in our case it is injected in the route handler and the search component).
• Only items that yield some search resuts are added to the cache.
• The cache is persisted to localStorage, so you can view your search history after a page reload. localStorage is nicely synchronised when you clean the whole cache or each element individually.
• Each history position can be deleted individualy or the whole history can be deleted. Check out the controls on the search list.

CAUTION! The openweathermap api tends to be slow at times and tends to timeout too. It is not always like that, but sometimes the UX is pretty unpleasant :(
