Is Redux Dead? - DEV Community 👩💻👨💻
Other use cases can be what color theme is active, or even what experiments are active for a given user. Another very useful approach is using a small data-fetching library like SWR or React-Query to handle fetching and caching your API responses for you. To me, cached data isn’t really global state - it’s just cached data.

Discussion: Best practice redux + redux-saga application ... - GitHub
I write this post because I'm not happy with my current project file structure and I want to give a board to discuss this issue. There are tons of recommendations out there, the most of them are only redux specific. In fact, when using redux with redux-saga it should be integrated as one whole.
Why Redux Is More Relevant Than Ever Today
Over the last year or so I have encountered several opinions suggesting that the React ecosystem is r ecommending the deprecation of Redux in their projects in favor of moving towards “modern React” using the Context API.
Conclusion
Redux, in my opinion, is not only not dead — it is more relevant than ever. With the addition of Redux Toolkit, the state management capabilities surrounding Redux have gotten better than ever. New features introduced in Redux Toolkit, like RTK Query, seem pretty killer (I haven’t tried it yet, but I really want to).
What are most important, must-know aspects of React that are most common on interviews?
I'm trying to get a grasp of what is the difference between junior, which is my level, and mid/senior React knowledge. I know that mostly companies don't require from juniors extensive knowledge about frameworks so I focused mainly on Javascript, and for React I'm going to learn about 15-20 answers.
React antipatterns to avoid
This post describes some of the antipatterns most commonly seen in React applications and how to fix them.
Material UI v5 is out, and I'm unsure if I like the move towards Emotion as the new styling engine. Those who have experience with it, how has it benefited you in creating reusable themed components with overridable styles?
Title says it all. I'm very used to the makeStyles and withStyles syntax from MUI v4 and struggling to conceive how to best organize reusable components going forward in the new v5 styling format. I'd love to hear people's experiences with Emotion and how it benefits your workflow.
Collection of Most Frequently Asked React Questions & Answers
Here's my list of commonly asked React interview questions and answers for beginners. If you are just getting started with React, you may find it helpful.
Reddit's new UI is made in React and is slow compared to the old UI. I'm not bashing React, only curious what mistakes possibly were made on migration? Let's speculate!
There are several places that could provide some clue to React gurus here who know the framework well. It's the general content loading speed difference between old and new that is my pmain point of interest. Content inside list divs is slow to load, whether main content view, chat or alerts.
Why unit tests are extremely difficult to write!
I've been trying to write unit tests with jest and react-testing-library for such a long time. But I waste a lot of time and it's extremely difficult to write a test especially when I'm using libraries.
Are hooks the main way to do things now?
If there is one thing i’ve noticed when looking for help with React it’s that there is a large mix of people using old and new methods. Many solutions on SE are still using class components with methods like componentDidMount or ‘this’. While other fewer solutions are using modern hooks with state and useEffect.
React 18 is awesome
I have been using React 18 on my personal website since the alpha stage. And I have to say, it is a big improvement in terms of performance, mostly on TBT.
LPT: If your font name has a number in it, wrap it in quotes before passing it
I spent 3 hours yesterday trying to get Google's "Press Start 2P" font working. No matter how I imported it into my app, it wouldn't show, and the app didn't show any problems (even in the CSS inspector).
What is the feature of Redux?
Another great feature of Redux was how easy it was to use with React. Not only was it a great match with the programming model of React, it also solved the prop drilling issue! Just “connect” whatever component you want to a store, and you had access to any part of the application state you wanted. It was like magic!
What is redux used for?
Another use case is for very interdependent states, or states that are derived from several other states.
How does Redux work?
The actions were sent to a “reducer” function, which returned a brand new copy of the entire application state, which would then propagate across your application.
How did react revolutionize front end development?
React revolutionized front end development as most people knew it when it was first released. This new approach to writing code triggered incredible innovation in how to handle state changes and UI updates.
Does Redux have a dispatcher?
With all its elegance and popularity though, Redux did have a few major downsides. For each new way of changing the state, you had to add a new action type and action creator, probably a dispatcher and a se lector, and then you’d have to handle that new state change in an existing reducer, or create a new one. In other words - lots and lots of boilerplate.
Does React 16.3 have a context API?
When the 16.3 version of React was released, it finally shipped with a fully redesigned context API. With this new feature, prop drilling was suddenly as easy as wrapping any subsection of your application in a context provider, and fetching it again with a context consumer component. Here’s an example of how that could be done:
Who invented Redux?
While many famous open sourcerers were busy fighting over which slightly different implementation of this was the best, a young Russian developer named Dan Abramov introduced an implementation based on the Elm architecture, called Redux.
Use case: caching HTTP responses
We can now use the ReactJS Context API. For those using GraphQL, the Apollo client does some caching as well.
Global vs. Local state
In ReasonML / ReasonReact, the future of ReactJS, reducers are built into components, but at the component level. There's no global state by default.
REST
GraphQL is quite popular among the ReactJS community. The TL;DR is that at the heart of React is the ability to colocate all of a components markup, styles and behavior. With GraphQL, we can colocate a component's data as well.
