/todos.json has a nested object which represents a assigned user itself.

normalizr

Convert /todos.json to the flat structure which consists of result and entities.

{
  result: [{todo: "todo:1"}],
  entities: {
    todos: {
      "todo:1": {
        "id": 1,
        "body":"ticket #1",
        "status":1,
        "userId": 1,
        "user":"user:1"
      }
    },
    users: {
      "user:1": {
        id: 1,
        name: 'john'
      }
    }
  }
}

Entities represent data itself, like a database record.

Result represents api result, but it has the entity id only.

Reducer

result

Other reducers handles results. In most cases, it updates a list of entity ids, for example, appends(prepends) a new entity, remove a deleted entity.

Container(Smart Component)

Container receives a entity id or a list of entity ids as props and get entities from Provider provided by redux-connect(https://github.com/reactjs/react-redux).
