import uuid from 'uuid/v4';
import {reducer as todosReducer} from './todosRedux';
import Todo from './todo';
import createMigration from './redux-persist-version';
import logger from 'redux-logger';

export const initialState = {
    app: {
        version: "0.1.0"
    },
    todos: []
};

const manifest = {
    migrate: (state, version) => updateState(state, version),
    migrations: [
        {
            version: "0.0.1",
            version: "0.0.2",

        }
    ]
};

const migration = createMigration(manifest, "app");
const enhancer = compose(applyMiddleware(logger), migration, autoRehydrate({log: true}));

export const store = createStore(todosReducer, undefined, enhancer);

function updateState(state, version) {
    switch (version) {
        default:
            return state;
    }
