Writing a simple store as a reducer

alt-store-reducer.js

import Alt from 'alt'

const alt = new Alt()

const CounterActions = alt.createActions({
  inc: x => x,
  dec: x => x,
});

const CounterStore = alt.createStore({
  displayName: 'CounterStore',

  state: { counter: 0 },

  reduce(state, { action }) {
    if (action === CounterActions.INC) {
      return { counter: state.counter + 1 }
    } else if (action === CounterActions.DEC) {
      return { counter: state.counter - 1 }
    } else {
      return state
    }
  }
});
