-## Vue architecture
+## Examples
 
-All new features built with Vue.js must follow a [Flux architecture][flux].
-The main goal we are trying to achieve is to have only one data flow and only one data entry.
-In order to achieve this goal, you can either use [vuex](#vuex) or use the [store pattern][state-management], explained below:
+What is described in the following sections can be found in these examples:
 
-Each Vue bundle needs a Store - where we keep all the data -, a Service - that we use to communicate with the server - and a main Vue component.

+- registry: https://gitlab.com/gitlab-org/gitlab-ce/tree/master/app/assets/javascripts/registry/stores
 
-Think of the Main Vue Component as the entry point of your application. This is the only smart
-component that should exist in each Vue feature.
-This component is responsible for:
-1. Calling the Service to get data from the server
-1. Calling the Store to store the data received
-1. Mounting all the other components

-The Service is a class used only to communicate with the server.
-It does not store or manipulate any data. It is not aware of the store or the components.
-We use [axios][axios] to communicate with the server.
-Refer to [axios](axios.md) for more details.
