# State management

Both remote and local state are managed by Apollo Client. Apollo + Vue integration is provided by vue-apollo package via Vue CLI plugins. All the Apollo relevant configuration and data for both remote and local sides is located in src/state directory, including global queries and mutations.

apollo-link-state allows using the already existing Apollo store for managing local state instead of including an extra store like Vuex. This means that, in order to access or update your local state, you use GraphQL queries and mutations just like you would for data from a server. Apollo's caching and offline persistence are also supported for local state out of the box. On top of that, Apollo DevTools are also compatible for debugging your store. Local state is stored in src/state in shape of resolvers and defaults.

To wrap your head around our state management, have a look first at Apollo Client introduction and then at Vue Apollo integration docs. Finally, read apollo-link-state docs for more information on local state management.
