hey i’ve been following for a while now and this is solid. no gimmicks. pure education, learning and excellent content primarily focused in TS and JS +frameworks. would love to see Rust and wasam content integrated with js. excellent work. can’t wait to see your channel blow up beyond 100k.
Love how you Made the comparison between Context and Zustand. I always use Context and didn’t see why I should consider other state management tools. Thank you Jack
Hey Jack! Thanks for creating these kinds of content 🙏 I am in this stage of my career where I was positioned to coach jr developers and TBH as usual, impostor syndrome kicks in 😅 Hence, I know I need to put the work to shake off that and learning your contents helps me to have that confidence that I know I will be able to help them grow. I really appreciate it and I will pay forward the learning that I am getting from your contents 🙏
I don't understand why youtube didn't recommend your channel to me earlier. This video is not only about mastering React context but also the way you refactor/repurpose the components for the use of context and other state managers. Thanks so much because I learn a lot from it.
Incredibly clear and helpful demo. Please keep doing what you're doing. Your channel is by far the best I've found at showing both "the how" and "the why" of very specific and practical React + TypeScript in a very accessible way.
It's really neat how you go building the example structure till you get on the topic of the video instead of already showing everything done and and explaining. I really liked that :D
WOW! I mean really WOW... You are such a GREAT teacher. Teaching with examples and passing down all that precious knowledge with such an ease. Brilliant. I'm a fan. First video I watch on your channel and I'm subbed forever. I just started learning React 2 months ago and this helps a looootttttt. Thank you sooooo much man. I'll keep coming back for more knowledge as I need to get a job very soon, hopefully.
You did it again. I'm a developer for decades now and to be honest, I'm getting very annoyed by all those wanna be's out there. I'm trying to level up my knowledge about react (although I hate it) and every ninja is telling you to use context for global state. My guts feeling told me that is not a good idea. I don't want to rerender everything to update some fields. I even think that prop drilling is better. I follow your channel for a long time now and I'm glad you gave me the answers I was looking for. In a decent and professional way with proper knowledge and terminology. Thank you!
I always asked why people use redux for everything, while they could achieve the same with context or simpler state management libs. This video is proof of it. Unfortunately using context takes a lot of care to avoid re-renders, but zustand demonstrate it can look simple and do the job.
Mastering with the MASTER 🔥Every video is great, sometimes too much 😄, I mean I have seen the video even twice because you reach a high level, but with you Jack, I can improve my skills. Thanks ✌🏻
So much great things covered in this video. Also a shout-out for passing the set state as a prop and using the callback to get the state value. I never thought of that before!
The comparison is really good, especially with the profiler. Didn't know that context will make those many changes to the tree. Thank you Jack for the awesome video!
This is a really really awesome video. Way Way better than all those tutorial style videos which only is a regurgitation of documentation. This actually deepens my understanding and give me ability to judge new state management tools for myself
Amazing content, I have been following the channel for a while now. As a Junior dev I can say that this channel motivates me to dive deeper into concepts and try them out on my own in a series of little projects. Keep up the good work and high quality content, Jack!
I am pretty impressed with how easy and clearly he manages to explain these concepts... Zustand sounds pretty interesting, I am definitely gonna try it.
Another great video….it’s amazing how many little things I learn mixed in with the major topic stuff. Thank you! Also, you are a great salesman for Copilot…the more I watch you write code the more I want it!
Finally I got the answer of this famous question, what is difference between redux and context. Your channel was always the best. I guess every body can find their question's answer in your channel. good to have you jack🤩
Love this channel!!!!!!!!!!! My go-to for React/JS stuff cause it covers more than just the basics which is what is needed in the real world env. Thx for the vids Jack!
I am getting the error "RangeError: Maximum call stack size exceeded" and it is pointing at the "useStore" custom hook. This happens when I start using Context and context-selector. 25:38 Replacing Zustand With Context 29:37 When Context Updates Components 30:10 Context Using use-context-selector
Thank you for the wonderful video, Jack! I work in this industry for 5 years and yet I found all of your videos amazing and incredibly informative! All your videos are precious gems :) Only one thing I found a little bit hard to follow is the pace you go through your code in the editor. Personally, for me is a little bit hard to follow with that speed. May be for others is okay :) Thank you once again for the cool stuff you're showing to our fellow programmers :)
Let me just say what no one else notices… your video lighting and green screen setup is superb! 🙌 As a video guy I know this takes a bit of a setup/tweaking to get such a clean key without green spill around you.
one reason I favour the state managers over the context api is that you can access your state even outside your react components and sometimes thats a requirement. not sure if you can do something like. import contextApi from 'mycontextapi'; contextApi.value ... etc.
You are correct. Making the data in the context available externally would be something you would have to implement. But there is `useSyncExternalStore` that you might want to look into. It's designed specifically to connect React components to external state managers. So if something off the shelf doesn't fit your needs there is that.
thanks for the ecommerce example, adding it to the project section in my resume. A full fledged ecommerce app with login logout and add to cart functionality 😎
Should your store.ts hold functions to make api requests? e.g a refreshData function might need to fetch data from an api and save it to state? can this be done in a single function e.g a useRefreshData hook? Struggling to understand what are the limits of this store AND looking for examples/information around using state manager and facade layer. if you have any
@@jherr yes sir, most usually using d3 on advance destructuring data, now on my project using context on development, until now I dont have any problem, I don't know when in the future, I have setup using sql to query data.
Hey Jack I have been watching video after video of yours. I am still in my deep dive of React and MFE's so would be curious if you had a video on managing State / Context via Module Federation, specifically around JWTs and how to control flow in MFEs for valid / invalid sessions. I'll keep looking through your library but this video along with every video you make is so informative. Thanks for publishing such amazing content!!
I used to use Redux (Redux toolkit to be precise) and it's still used for one of my active projects but in my latest project where I created my own CMS from scratch I used purely React Context for local state management and it was a very good experience. It's not like I dislike Redux toolkit (which is a pretty big upgrade on regular Redux imo when it comes to dev experience), but it was really nice to not have to put in a ton of dev time for the project on just state management.
Yes. Though realize you'll probably have to sources of state. RQ for the response data from services. And Zustand for all the transient user state as they use the UI.
I have kind of learned HTML a thousand times over the years and skipped it because JS and CSS where so cool but HTML is so basic it is thought only to beginners I think you are the perfect person to teach us (i.e. We already know * "Hypertext" refers to links that connect web pages to one another, either within a single website or between websites*) you must do an HTML tutorial for people who knows the basics and give us the advanced tools to master HTML in the context of React and with the minimal CSS or styling possible for it to be interesting but focusing only on HTML (in the context of React probably)… 😅😅😅😅 I would love to get my HTML certification 😉😌😜
Does use-context-selector support multiple contexts? I really like Zustand but then I realised it did not really fit in one of the projects I was working on as it didn't support multiple contexts, which was required for that project, unlike the context provider (please correct me if I am wrong) 🤕🤕
Thanks Jack great content . Btw is there a solution in zustand for creating state slices and naming them so when project gets bigger we can inspect them by redux toolkit with the slice names ? ( i can combine at store but they are spreaded in toolkit).Thank you..
Jack, you are so amazing. I would be so happy if you can create full stack web development course. I am sure many people (including me) are willing to pay for your course.
@@jherr I would appreciate if you could share your thoughts (either here in the comments or in a video) regarding on how you use Github Pilot and what pros and cons it has for your workflow. Thanks!
what about jotai + valtio. I think we are moving toward an atom based state managers, and the proxy pattern reduces the boilerplate of writing selectors
Since setting state in the client component function body, also gets run on the server side, the app consumes a lot of server memory when I have a lot of stores. 😥
While I'm kind of already familiar with this concept, I still learn some new stuff here and there when you explained it. Thanks! By the way, what extension do you use for that autocomplete?
Even though we are not doing prop drilling, the all the components still re-renders. Isn't this the performance issue? Shouldn't only Counter one should re-render?
@@jherr 9:06 So, I thought that when you use this context method, only AddCounter and Counter components should render and not Container or Container's parent.
@@codedusting I don't have a ton of time to watch all the context around this but whatever component has the Provider, which has a useState, is going to be updated because when the state is set the provider and whatever included it is going to be re-rendered.
I use ScreenFlow to capture the screen. If I drew on the screen then I was using ScreenBrush and a commodity Gaomon drawing tablet. And then for post production I use the Adobe Suite. Honestly through, in most cases you could get by the just using ScreeFlow and a decent microphone.
honestly this channel is probably the best out there for deep dives into Typescript and React, love your content good sir

Great team advice too, even you know the libraries already, "What is easier to review?" is a helpful perspective.
I was 2 videos and decide to subscribe. This channel got the real stuff compared to so many other RUclipsrs pretending to be professional developers.
True, this channel deserves to be much bigger - lots of knowledge and very good production quality.

Just when wet thought we don't deserve this a high quality educative content, you showed up and said we deserve it.
Thank you for this episode. In my personal ranking this is the best Context explanation I've ever seen
There is a ton to digest here. Will be watching this many times. Thanks Jack!
I think this video changed my life. Well, my frontend architecture but same thing right now.
Exactly what I needed, still getting familiar with React and Next JS. Thanks!

At the 3:00 mark, how would you write the same code in typescript?
AddOneButton: React.FunctionComponent number) => void} = ({setCounter}) ...
How would type and set a default value for the context with useState using typescript?
I usually create an `initialValue` object and then set the type of the context to be `typeof initialValue`.
Should your store.ts hold functions to make api requests? e.g a refreshData function might need to fetch data from an api and save it to state? can this be done in a single function e.g a useRefreshData hook?
Struggling to understand what are the limits of this store
AND looking for examples/information around using state manager and facade layer. if you have any
A "store" is just a separation of concerns between UI and the business logic. It's limits are whatever you want in terms of architecture.
How about spatial data? What's the best options to use?
Spatial data isn't my specialty. Doesn't that usually involve specialized data structures optimized for dimensional search?
