It added the React.createContext() function, and the associated and components.Ĭhanges this big are guaranteed to cause some excitement.

It decoupled context from components removing the need for the getChildContext() method, or the ntext property.

To learn how to use the new Context API, see React’s official documentation. React’s new context API changed a lot of stuff. Up until React’s new context API was released, it wouldn’t have been all that controversial to say “just use Redux.” But a small change to how context works has reignited the debate.

If you want a tool to help you manage your state, then Redux is a great choice.īut what if don’t want middleware support or time traveling debugging? Should you still use Redux just to take advantage of its ability to prevent unnecessary renders? Context won’t give you time traveling debugging, configurable middleware, or anything more than a way to get data from one place to another. Its React bindings prevent many unnecessary rendersĪs you can see, context is not a replacement for Redux.It provides a middleware API, giving you access to tools like redux-sagas.It comes with a time traveling debugger.In contrast, Redux provides a whole toolkit for managing state: React’s context API does basically the same thing it lets you pass global state down the component tree without passing it through props at every level. Of course, Redux isn’t the only way to provide data to your components. Along with the component, connect() lets you pass global state to any component in your application, without manually passing that data via props.

Of all of Redux’s features, its connect() function is arguably the most frequently used. And this raises the question: if Redux has been using context all along, how can context replace Redux? #The rumors of Redux’s demise have been greatly exaggerated Redux’s component has actually made use of context since 2015, when Redux was first released. So in a way, context can replace Redux.īut wait a moment. In fact, the Redux and React providers both do roughly the same thing. And if one of these names sounds familiar, it’s because Redux also supplies a component. Starting with React 16.3, the context API involves the use of two special components: and. And being as important as it is, you may have heard that the context API recently received a major update. It’s used everywhere from theming, to navigation, to graphql tooling. The React context API is one of the major forces behind the most useful packages in the React ecosystem.
