Ref: Examples

import {createStore} from 'circuit';

const initialState = {
  total: 0,
};

function reducer(state, action) {
  switch (action.type) {
    case 'COUNT_UP':
      state.total += 1;
      break;
    case 'COUNT_DOWN':
      state.total -= 1;
      break;
  }
  return state;
}

const store = createStore(initialstate, reducer);

store.getState();
// same) getState();
// result) {total: 0}

store.dispatch({type: 'COUNT_UP'});
// same) dispatch({type: 'COUNT_UP'})

store.getState();
// same) getState();
// result) {total: 1}

store.dispatch({type: 'COUNT_DOWN'});
// same) dispatch({type: 'COUNT_DOWN'})

store.getState();
// same) getState();
// result) {total: 0}

[Recommend] Rules

• Action creator can dispatch only one action.
• Action should have type property.
• Reducer should return new state.
• Readable state by getState anywhere.
