Helper for create action creators. Action types constants + action creators functions now cames together.
// Actions:
const actions = createActionCreators({
increase: null,
decrease: null,
increaseLater: (payload, actions) => dispatch => {
setTimeout(() => dispatch(actions.increase()), 1000)
}
}, 'counter')
// > actions.increase()
// > { type: '@counter/increase', payload: null }
// > actions.increaseLater()
// > { type: '@counter/increase', payload: null }
// > actions.increase(1)
// > { type: '@counter/increase', payload: 1 }
// Redux store
const store = createStore((state = { count: 0 }, action) => {
switch (action.type) {
case actions.increase.type:
return { ...state, count: state.count + 1 }
case actions.decrease.type:
return { ...state, count: state.count - 1 }
default:
return state
}
}, applyMiddleware(thunk))
// Often it happens in react-redux mapDispatchToProps
const boundActions = bindActionCreators(actions, store.dispatch)
// > boundActions.increase()
// > store.getState()
// > { count: 1 }
