Redux vs React’s Context API

In other words, Redux gives you code organization and debugging superpowers. It makes it easier to build more maintainable code, and much easier to track down the root cause when something goes wrong. Redux is a predictable state management library and architecture which easily integrates with React. At Codehouse our expert development team is constantly exploring new technologies that will improve the development process and also the end user’s digital experience.

That’s why Redux became popular, it solves that problem! It also helps with routing where we might not be using our components via JSX. Technically, Redux is not limited to usage in React apps – and indeed there are implementations in other technologies, too (e.g. NgRx for Angular). Ultimately, deciding between React Hooks vs Redux is a matter of preference.

Fantastic closures and how to find them in React

An action is something that occurred in the application, and an event is anything that summarizes that event. Redux needs actions, reducers, and storage as its three primary building blocks to operate. They allow you to use more React capabilities, such as keeping your component’s state constant or even running an after-effect when certain state changes occur. Any dynamic software must have state management as an essential and unavoidable part.

  • To be able to follow along, you have to know at least the basics to advance features of React and particularly React hooks.
  • It should be quite clear right now, but it’s worth it to stress again that hooks and Redux are definitely not in each other’s way.
  • Inside the src/store directory, let’s create a file called index.js.
  • This makes the app run faster without having to load the same elements all over again – they’re simply stored in Redux.
  • While using Redux it is less likely to cause problems in your application due to state mutation.

Hooks are functions that allow you to use different React features in your components without writing a component class. In most programming projects, you may need to use variables to represent data that changes. These variables can be structured in a javascript object that holds information in properties. Redux is an open-source JavaScript library for managing application state.

What is Redux vs React

Proper state management stops us from passing props to deeply nested components, which is called prop drilling. In some cases, we need a global state but not everything should be in a global state so proper management should be done. Singletons are a code-smell that could indicate shared mutable state, which is the real anti-pattern. A context helps us to handle state without passing down props on every component. To implement it, we need to create (it’s optional) a new folder named context in our project, and add this code below to aricleContext.js. Managing states in a React application is one of the biggest challenges for many frontend developers.

To really understand the difference between Redux and Recoil, let’s quickly create a simple React Native application that increments a counter with the click of a button. The Context API (currently) is not built for high-frequency updates (quote of Sebastian Markbage, React Team), it’s not optimized for that. The react-redux people ran into this problem when they tried to switch to React Context internally in their package. The fact that updates to the data passed to value are received by consumers of our Context and allow us to use the Context API as a global state management tool. With the Context created, you can now provide it to all components that should be able to interact with it (i.e. read data from it or trigger a method stored in Context – more on that later). But passing props around like this makes your components harder to re-use since they have to handle props they don’t need.

It passes a “create” function and an array of dependencies. UseMemo will only recompute the memoized value when one of the dependencies has changed. This optimization helps to avoid expensive calculations on every render. Redux aids in shared state management but comes with compromises, like any technology. More ideas need to be mastered, and more code must be developed. Additionally, it requires you to adhere to specific limitations and adds additional indirection to your code.

It is very easy to create a store once you have reducers. We are passing store property to the provider element, which wraps our route component. why redux The process of subscribing to the store, checking for updated data, and triggering a re-render can be made more generic and reusable.
