In this video we will learn about Redux and Redux Toolkit. Redux is a state management library that makes it really easy to have global state in your React application. We are going to learn how to work with modern Redux, using Redux Toolkit to save ourselves some boilerplate code. This is the last video you will ever have to watch on Redux with Redux Toolkit! Enjoy!

Hey everyone! I just launched 🚀 Project React, which is a course that teaches you React by building a real-world project. It goes way beyond what you see in these videos and walks you through step-by-step on how to build a big and complex application with React! You can check it out here: cosden.solutions/project-react

You're an awesome teacher, i legit paused a complicated redux tutorial i was watching yesterday when i saw your post notification for this one and i'm glad i did. Great work bro

@@cosdensolutions Hi @cosdensolutions @cosdensolutions ,Thanks . As you said , if redux copy the whole state and update the modified proerty in the copied state and replace the while orginal state , my doubt is , do we get performance issue , if our application has more state variable ?

I also impressed how he memoizes, does, and casts things in numerous videos, I'd rank him in a row with Shwarzmuller

Really helpful. Thank you! Im a pretty experienced FE dev who has never used Redux at my previous role(we used zustand and everything else was handled through services) and I have a technical interview tomorrow, they mentioned redux and I was like yowzers I need a refresher. Now I feel like I get it!

[@rameezh88]

Thank you very much for the video. Out of many channels that I watch, I find that I get the greatest understanding and value out of yours. Please keep going! Another request is, could you make a video discussing different middleware libraries for Redux such as Sagas and Thunk?

[@Thassalocracy]

Thank you for this video. U certainly did explain quite clearly how RTK works and the best thing is, u even included how to work with typescript and thunks, which so far I've not seen other videos do. My opinion after watching this, and also after reading what Dan Abramov wrote (what somebody above me said), is that sometimes we will still need redux for the fact that the native Context API does not sufficiently cover all use cases for state management. Therefore knowledge of redux is still good to have in 2023/2024 🙂

[@cosdensolutions]

yeah totally, Redux is still valuable and will be for a long time. There are a ton of new projects choosing to use it daily because it's really good. Imo context isn't good enough to cover most state management use cases. You really need a dedicated library for that!

[@sarakaterji]

Been using RTK for the better part of the year, with it all being a bit hazy in my head, mostly using RTK Query and the caching! You’ve just mind blown me with this basic, but very clear, tutorial. I the spirit of the store and data fetching. Do you think you could make a video on persisting the data? (Unless you’ve already got one on your channel!) thanks a bunch, plus, I no longer feel alone with keyboard typing issues! 🤪

[@cosdensolutions]

hahaha the keyboard typing!! Yes I might look into persisting the data with redux, I think it's as simple as using redux-persist but might be worth for a tutorial!

[@harag9]

Been going through all your videos to learn react and found them really great to follow, left this one as the project I took over at work doesn't use redux, finally got around to watching it. Makes me wonder why we don't use redux as it looks really good, sort of state management (we use context) and useReducer hook rolled into one. Just to confirm, when using "useState" vs useRef, the use state forces a redraw but useRef doesn't.... So what is forcing the redraw -- is it whenever you call "dispatch(...)" so just like when using useState. Also - great tip at the end, thanks for the heads up on the extension :)

[@cosdensolutions]

Without Redux, useState is causing a re-render and useRef isn't. With redux, it's when you dispatch the action. It then goes to the store which gets updated, and components receive the updates through the selectors if they're listening. This all works through context btw, using the Provider from react-redux, so it's pretty similar! I'm not sure why people don't use Redux too much. It used to be a lot more complicated in the past, but now with RTK it's so much better. But sometimes it may be overkill for a project, it depends. I really like it as well!

[@harag9]

@@cosdensolutionsGreat, thanks for confirming that. Not looked at RTK Query yet. just messing around with the basics first :)

I have been struggling for months to make sense of the concepts of store, actions & reducers . Honestly your video here has finally helped me crack the code.I actually was led to your KZbin channel from your TikTok page.Thanks for the very incisive tutorial.You're a rare breed!!! However I am still struggling to run the Social Echoe app locally.I guess it has to do with dependency version issues??

what theme do you use mate ? , thank you for this video !

[@MarlonEnglemam]

great video. I've always liked and tried to use redux toolkit since the first time I came across it! I have one question though, I'm planning to add redux toolkit to deal with states in the react application I'm working on but it's not completely clear how to deal with HTTP responses from the backend services, what I mean by that is: let's picture a scenario where I call a service layer/endpoint from inside the async thunk action, is it ok for me to just return its response back to the JSX component that dispatched that action? or is it better if I simply use its response and deal with it inside the redux slice and use states to update the user interface (with a toast error message, let's say)? (consider that I'm not using RTK query to deal with HTTP requests, instead I'm gonna have a service layer with classes that will receive a axios instance and then make the HTTP calls)

[@maykiteplanet]

Thank you❤

[@gaytanlugo4821]

Amazing explanation. I have one question: What would you recommend between RTK query and thunks, and which is more commonly used?

[@cosdensolutions]

I would go for RTK since it's built to work with Redux, but you can also handle your own APIs using thunks if you want or if you are working in a project that has it setup like that

[@turgunov28]

amazing 🔥
