That said, they both allow you to pass data without having to pass the props through multiple layers of components. On clicking on an item we are marking it as complete and when clicking on X button we are removing it from the list.įinally, let's wrap our two components with our Provider. Both Redux and Reacts Context API deal with 'prop drilling'. In the Context approach, even the smallest of changes to the store could cause the component that is using it to re-render if used improperly. So you should feel much safer using context via React Redux than directly because if it changes, the burden. The main advantage of Redux over Context is its optimization. React Redux uses context internally but it doesn’t expose this fact in the public API. It comes with React and is part of its toolkit.
#React context vs redux update
Its up to Redux to actually update its implementation to adhere with the latest Context API. Context also does not require any external packages to work.
#React context vs redux code
So you should feel much safer using context via React Redux than directly because if it changes, the burden of updating the code will be on React Redux and not you.

So, when the application needed its first centralized state, I told myself 'Lets make it much simpler, lets use React context instead of Redux'. We are mapping through the todoList and rendering the todo items and a remove(X) button next to it. React Redux uses context internally but it doesn’t expose this fact in the public API. An in-depth look at state management in by Denny Scott Better Programming 500 Apologies, but something went wrong on our end. In TodoList component, we are using useContext to subscribe to our TodoListContext and getting todoList state, removeTodoItem, and andmarkAsCompleted dispatch functions. Let our todo app have three actions - add, remove, and toggle completed. In this post, we will create a good old todo list example using Context and useReducer hook.įirst, let's set up our initial state and actions. Dan Abramovĭan said this way back in 2016, and now that we have React Context and useReducer hook, the use cases of redux is very minimal. It is older than React 16. But we all know that the real question is hidden in the context. If you ask literally what to choose, Context or Redux the answer is RTFM.
I would like to amend this: don't use Redux until you have problems with vanilla React. Redux is for managing the state of the application, Context is for passing props.
