We’ll need to wait until the suspense API lands to see if it can replace my saving/loading patterns in Redux. Redux allows us to cleanly separate side-effects from the rest of the component logic without requiring us to mock I/O services. (Isolation of effects is why I prefer redux-saga over thunks). In order to compete with this use-case for Redux, React’s API’s will need to afford effect isolation.
- In my view, there is little overlap between hooks and Redux.
- We just switched from context and hooks over to RTK on one of our production application’s frontends.
- The parent component that renders a is responsible for deciding what value is passed into the context, and that value typically is based on React component state.
- Even though Redux solves our state management problem, it is time-consuming to use, has a difficult learning curve, and introduces a whole new layer of complexity to our application.
- The action object would specify what the type it is, and also payload to contains other useful information.
One thing you need to understand is that hooks aren’t meant to replace redux stores nor are they used for global store management. You use redux so that multiple components in your app can use the same redux store. The most popular way to handle shared application state in React is using a framework such as Redux. Quite recently, the React team introduced several new features which include React Hooks and the React Context API. These two features effectively eliminated a lot of challenges that developers of large React projects have been facing. One of the biggest problems was “prop drilling”, which was common with nested components.
When to Use Redux
But, they never state that explicitly – they just say “I’m using Context”. That’s a common cause of the confusion I see, and it’s really unfortunate because it helps perpetuate the idea that Context “manages state”. So, clearly these are very different tools with different capabilities. The only overlap between them, really, is “can be used to avoid prop-drilling”.
This forces Redux Query to get the name fresh from the backend. However, over the last year or so, React Query has been gaining popularity quickly as an alternative to React Redux. Last year, React Query had only about 120k weekly what is redux downloads, but as of October 2021, React Query downloads are nearly six times more frequent, at nearly 700k downloads per week.

Whenever the parent component re-renders and passes in a new reference to the context provider as the value, any component that reads from that context will be forced to re-render. And we can use any of the handlers we pass as values into to update the user authentication states. And finally, we save states and handlers into our global context, for the nested components to get direct access to. We firstly import the action constant from store/actions/action_types.js.
With React v16.3.0, the Context API was released, which allows developers to implement global state without installing additional libraries. Hooks are functions that enable the execution of custom code in React’s functional components. They allow us to hook into React’s core features and handle state management easily. Context provides a way to pass data through the component tree without having to pass props down manually at every level. Essentially, the React Context API is React’s way of managing state in multiple components that are not directly connected.
The useContext Hook

When comparing development time, you can relate it to reducing application size by avoiding the installation of redux and react-redux libraries. At least – I’m going to try hooks first on my next project, before just jumping into Redux. However, for complex projects, with multiple developers – I wouldn’t rule out Redux just yet.
Redux
Sometimes using React Hooks is efficient enough, sometimes it is not. We can use context to share a global state (that we keep in a reducer) with multiple components. When the button is clicked, it triggers the dispatch function with the specified action type, which will be handled by the reducer function to update the state accordingly.
Nonetheless, React is quickly become a classic example of functional programming techniques, what with its’ pure components. All in all, an enjoyable technology to work with that brings some sanity to front-end user interfaces. Singletons are a code-smell that could indicate shared mutable state, which is the real anti-pattern. The state it cares about is shared between components, not localized to a single component, it’s persisted rather than ephemeral, and it potentially spans multiple page views or sessions. These are all things that local component state won’t help with unless you build your own state container library on top of the React API — and that’s a lot more complicated than just using Redux. It allows you to declare and set state variables in functional components, making it easy to handle component-specific data.
What do hooks give us?
You don’t always need Redux for every app, or every component. If your app consists of a single view, doesn’t save or load state, and has no asynchronous I/O, I can’t think of a good reason to add the complexity of Redux. 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.
If the backend returns an HTTP success, the saga dispatches a success action. The success action causes a reducer to run which updates the value of the name in the store. To answer this question we will start with a simple todo app project using Redux and we’ll try to update it, to use the Hooks instead. If you decide to use the Hooks, you’ll not need to install any external libraries, and you can use `useContext()` to handle the global state of your application. As we learned above, hooks make it easier to encapsulate and share the logic.
Blogged Answers: Why React Context is Not a “State Management” Tool (and Why It Doesn’t Replace Redux)
Vue.js is smaller, and from what I saw (benchmarks) faster. React is more popular, and the adoption rate is much higher. So it would be easy for you and you wont reinvent the wheel again for mobile apps. But I’m personally using React, because React is changing the way I look at how JavaScript should be.
