React React with Redux Using Connect
Example
Create a Redux store with createStore.
import { createStore } from 'redux'
import todoApp from './reducers'
let store = createStore(todoApp, { inistialStateVariable: "derp"})
Use connect to connect component to Redux store and pull props from store to component.
import { connect } from 'react-redux'
const VisibleTodoList = connect(
mapStateToProps,
mapDispatchToProps
)(TodoList)
export default VisibleTodoList
Define actions that allow your components to send messages to the Redux store.
/*
* action types
*/
export const ADD_TODO = 'ADD_TODO'
export function addTodo(text) {
return { type: ADD_TODO, text }
}
Handle these messages and create a new state for the store in reducer functions.
function todoApp(state = initialState, action) {
switch (action.type) {
case SET_VISIBILITY_FILTER:
return Object.assign({}, state, {
visibilityFilter: action.filter
})
default:
return state
}
}
