What is Flux in Reactjs?
- we will show you how to implement flux pattern in React applications.
- We will use Redux framework.
- It can present you the simplest example of every piece needed for connecting Redux and React.

Step 1 - Installing Redux
- We will install Redux in command prompt window.
Step 2 - Create Files and Folders
- In this step we will create folders and files for our actions, reducers and components.
- After we are done with it, this is how the folder structure will look like.

Step 3 - Actions
- Actions are JavaScript objects that use type property to inform about the data that should be sent to the store.
- We are defining ADD_TODO action that will be used for adding new item to our list.
- The addTodo function is action creator that returns our action and sets an id for every created item.
actions/actions.js
Step 4 - Reducers
- While actions only trigger changes in the app, the reducers specify those changes.
- We are using switch statement to search for a ADD_TODO action.
- The reducer is a function that takes two parameters (state and action) to calculate and return updated state.
- The first function will be used to create new item, while the second one will push that item to the list.
- At the end we are using combineReducers helper function where we can add any new reducers we might use in the future.
reducers/reducers.js
Step 5 - Store
- The store is the place that holds the app's state.
- It is very easy to create store once you have reducers.
- We are passing store property to the provider element which wraps our route component.

Step 6 - Root Component
- The App component is the root component of the app. Only root component should be aware of a redux.
- The important part to notice is the connect function which is used for connecting our root component App to the store.
- This function takes select function as an argument.
- The select function takes state from the store and returns the props (visibleTodos) that we can use in our components.

Step 7 - Other Components
- These components shouldn't be aware of the redux.
components/AddTodo.js
components/Todo.js
components/TodoList.js
Output
- When we start our app we will be able to add items to our list.
