If the APIs we are using are providing GraphQL then sure! I would not require an API team to build a GraphQL API only for a frontend application. There needs to be multiple consumers or higher business value for that GraphQL API, otherwise, we cannot justify the added complexity server-side. But when you are dealing with an application that will grow and be used by many users, you need a convention defined for you and your team to follow.
This is where state management tools come into play, enabling developers to view, control and synchronize the ‘global state’ of an application across all of its components. Managing state when building complex tasks was quite a pain in the neck until Redux came along. Inspired by Flux an application design pattern, Redux is designed to manage the state of data in JavaScript applications. Although it’s used chiefly with React, you can use Redux with different frameworks and libraries such as jQuery, Angular, or Vue. Actions send data from the application (user interactions, internal events such as API calls, and form submissions) to the store.
Redux vs. React Context: Which Should You Use?
By logging actions and state, it is easy to understand coding errors, network errors, and other forms of bugs that might come up during production. Technically, middleware are functions that call the next method received in an argument after processing the current action. It is highly recommended to keep only one store in any Redux application. You can access the state stored, update the state, and register or unregister listeners via helper methods. Now imagine what happens when a state has to be shared between components that are far apart in the component tree. The state has to be passed from one component to another until it gets to where it is needed.
Redux is one of the hottest libraries in front-end development these days. However, many people are confused about what it is and what its benefits are. The problem is in a large application, you are going to end up with a lot of state, and some of it will be related via keys, as well as state that is loaded later via API calls. React now supports Context, which can share the common state between components.
Can Redux only be used with React?​
Redux was invented in the first place to share a common state between complex component hierarchies.

This makes the app run faster without having to load the same elements all over again – they’re simply stored in Redux. If you’ve followed along with this tutorial, you should now have a solid understanding of Redux, both the traditional approach and the simplified version using Redux Toolkit.
Reducers are pure functions, which means they are predictable. A pure function returns the why redux same output for the same input. You can use reducers to generate a new application state.
We might need to update many places in the state at different times under different conditions. 1 To be absolutely accurate, it’s another library called react-redux that hands data to React components, not Redux itself. But since react-redux just does the plumbing and people almost always use Redux and react-redux together, I think it’s fine to include this as one of the benefits of Redux. Single source of truth, state is read-only, changes made with pure functions.

If you have a component structure like the one above – where props are being forwarded down through many layers – consider using Redux.
- Redux allows the use of a third-party library so that middleware can be accessed.
- The problem Redux wanted to solve is predictable state updates.
- The API interface is also relatively simple to use, once you get a hold of it.
- The reducer then uses a switch statement to check the “type” of the action, and based on that type, it updates the state accordingly.
You’ll also have a better understanding of how using Redux fits into a React app, and why Redux can be useful. If we had left our components communicating with each other, we would have created an error prone and unreadable codebase. In this post, I’m going to discuss Redux, how it’s deeply rooted in the concepts of functional programming, and how to decide if you need it in your application. If an object (state) changes only some values, Redux creates a new object, the values that didn’t change will refer to the old object and only new values will be created. You can’t dig into React without hearing a lot about Redux. However for many people who start learning, it can make no sense, they can’t understand it, or if they do it just seems like boilerplate code.
But every React developer should know the basics of how to work with Redux, since industry projects often use Redux to manage larger projects. If you build a game with Redux, you’d just need a couple more lines of code to save/load the game progress, without changing the rest of the code. As a simple example, in the Twitter app, when you click the heart on a tweet, it needs to request the server to do a few checkups, for example, whether that tweet still exists. Instead of waiting many seconds for the result, the app chooses to cheat!
