title: Angular 2, best practice to load data from a server one time and share results to components
body: <p>What is the best practice to store (and share) initial values in an Angular 2 application using a service?
  I have a service that loads much data from a server as resources,configurations and other that are array and objects.
  I do not want to load this data each time I load a component or when I route to a view, I just want to use these objects and array already loaded when the application starts, and optionally reload if needed.
  The question is where is the right place to store this values and how to share across components that use the service?
  Thanks.</p>
