All you need to know about the Context API | React Context API Crash Course

[@fallenZero12]

im really struggling to stop avoid unnecessary rerenders when using context api, you gave me the idea on how should i fixed it, thanks man

[@yasensim]

Thanks!

[@PedroTechnologies]

Thank you for the support!!!

[@mostafa2199]

Great video. I like how you didn't just explain how to implement context, but also revealed the drawbacks and mentioned where to use it.

[@lasindunuwanga5292]

Your knowledge was always incredible. Now your video graphics and etc. are also evolving... Great effort

[@PedroTechnologies]

Appreciate it! Happy to see u are liking the videos :)

[@songokussj4cz]

Hi Pedro. Really nice, as always. I really liked your video on "4 types of Fetch" because you divided that into different files like it would be in production. Here at 8:20 you're saying "And obviously I'm doing it in one file. But imagine how it would look if you separate that to more files". Please: these people (myself partly included) which are watchich these beginner videos have almost certainly a problem to see how it would work with imports and so on in those separate files. So my tip for next time, show it in one file, no problem, but then, for 5 seconds (at the end for example) show it separated to more files with good file names and file structure. Nearly all internet tutorials, for "simplicity" are showing everything in one file.... Be different! Be closer to production! Like you were in "4 types of Fetch video" :-)

[@sravyanandina]

Totally agree on this!!

[@jaimemedina3351]

Nonsense. The one file approach did a great job in showing the prop drilling tendency in React. Make your own videos before handing out 'tips'.

[@chippandenga6722]

@@jaimemedina3351 😂Nothing wrong with suggestions. I am sure the creator appreciates the suggestion.

[@tadakuniyasuda8214]

Informational, straight to point, friendly, and motivational. I really like how you give us your honest opinion near the end based on your experience. It helps us learners because we are overwhelmed by so many things to learn from. Now I am going to watch your hooks video. Thank you again.

[@byronk5]

I really appreciate how balanced and informative this is . Great delivery and excellent content.

[@ChitruShrestha]

Thank you for taking the time to give drawbacks and opinions and your preferred method. It really made it easy to wrap around broad concepts.

[@jaimemedina3351]

Good stuff here. I appreciate how the downside of context management is underscored. One really needs to think about state, but also the way the state changes.

[@frankiefab]

Thank you Pedro for this one. It came at the right time for me.

[@CodeWithClinton]

Awesome video Pedro, thank you so much for the knowledge shared.

[@matt112fly]

perfect- i just wanted to look into the context API :) u helped me with redux so im looking forward to context api

[@Aziz-kw6ct]

This video is a lifesaver, thanks a bunch!

[@berndeveloper]

Love your video man, thanks so much for the info!

[@hassamulhaq7762]

Really informative content. I love your suggestions where and when.

[@quelchx]

If you try to pass a null value into a createContext while you are using Typescript it will throw a warning. Yeah, you can change your tsconfig to ignore this (ignore null checks). There is a workaround, can't remember it at the moment -- but I figure I share this for the TS guys who might be watching this video while working LOL.

[@PedroTechnologies]

Yes! I use typescript at my job and on side projects, what I do is I create an object called `defaultValues` and also specify the format of the context with an interface

[@quelchx]

@@PedroTechnologies Sounds about right. I have worked on some code bases were I think we did something like that with an initial state or like this (been a while) const authContext = useContext({} as AuthContextType) the context type being an ts interface or however we did it I forgets and am too lazy to go back and look =)

[@heitormbonfim]

Bruh, you're a life saver

[@elwoseopenstepcrew1134]

i have the same feeling about redux and graphQL xd amazing video, subscribed ! great job

[@mdabidkalam3527]

I loved the way you explained.

[@saqibghouse]

Can you also make a video on best practices on react app file structure. and styling please

[@ytpeerz]

Thanks for the video, helped me understand the context API

[@geicianecosta3925]

Voce eh incrivel!!! Adoro seus videos :D

[@fabionunes2793]

A quick question: the re rendering is really a drawback the re rendering is a misunderstood feature of context? I mean, the name itself says, context. Is a thing to wrap components inside to warn these components, like: "hey, the state you want to show changed, so let's re render".

[@misscarla_alhambra7345]

THANKS! Was very informative and helpfull

[@BoredBricks]

Good timing, I needed this.

[@hood_love_189]

Thank you for teaching me this stuff...

Thanks pedro .. really need this tutorial hope you make next.js typescript tutorial

Great stuff as always. I pretty much use Zustand for everything these days.

[@SahraClayton]

Is Zustand any good

[@GabrielMartinez-ez9ue]

@@SahraClayton i like it a lot. It’s simple and no boilerplate as rtk

Thanks Pedro

Thats why i really like the vue team . They created pinia, and it has the solutions embeded in one solutions.

[@aeiou...]

Yeah. Hope pinia isn't tied to vue though

Do you have any video on react native?

Could you please talk about RxJs or reactive state managment?

[@pemadechen9199]

Thank you :)

[@kabagambedaniel2468]

let me watch this one, i always learn a lot on this platform

[@AM-nm6ts]

if I use several providers. where I should put them please. like this? thanks a lot

[@PedroTechnologies]

You can put them where ever you want! You could do it like this if you want to access all the data from each provider everywhere in the app. But you can also put providers inside of the app so that the data is only accessible inside of a group of components

[@AM-nm6ts]

@@PedroTechnologies thank you so much :) god bless you 🙏🙏

[@AhmedKhan-rt6oz]

very well explained

[@1989SeanSmith]

Could you add the starting code also, so that we can follow along from the beginning?

[@theintrovert894]

i am terribly confused why he call child compoenet if he can directly call grandchild

[@aeiou...]

Im just getting back to react. Why not use redux for this kind of problems?

[@AsifKhan-ee8ez]

When to use redux toolkit and when to use context api?

[@papa_ethan]

You know you are just explaining to yourself, and do not mind that the viewer does not have the ideas of what you are saying so you should show what you are saying. Remember the point is you are here in order to be understood.

[@ravisankar9122]

Excellent video.

[@slahomar1497]

Could you make Relay tutorial please

[@akaabdullah]

well i understand what you tried to tell so now please make a tutorial on REDUX

yo pedro, I create ContextProvider for socket io and use it for layout in react-router-dom element and use Outlet as a children inside that ContextProvider is that okay? previously I use builtin useOutletContext hooks provided by r-r-d but I have nested protected route so its throw and error.

We need tutorial on REDUX with react

[@oncoding4520]

So I planned to watch the video on the series of your react tutorials but this on is more longer so im going to start with these. I wanted to give you a gift but dont know how to contact you

[@oncoding4520]

watched and finished almost the hole series

[@AmitSharma-nr1wi]

You can send some money to him

[@chethananderson3446]

the changes made to this context object does'nt re-render the child components , you're passing the setUsername as a reference to the value prop, the reason why it is re-rendering is , you're making changes to the state by passing its setUsername reference and offcourse if a state in parent component changes the child component is re-rendered. Context API changes doesnt re-render it's child components.

[@filipevalentegomes2383]

Wrapping multiple components with context will turn into a big mess the bigger the app gets. It’s good to know, but I would never use it, there are just too many better options.

[@PedroTechnologies]

I agree! Thats why i try to use React query + composition in most cases. And use the context api for general states that are rarely mutated.
