so a quick tip for all i know most of you must already know this. at (14:38) Mount was executing first than fetch because fetch always return a promise which is async in nature thus JS engine will not wait for it instead and it will move to next line for execution. just printing mount firstly on console than the fetched Data. Thanks

You’re spot on with how programming learning works. I’ve been hearing useEffect as a buzzword for a while. I’ve used it but never really understood it, I just knew I needed it. This video helped a few things click. Thank you.

Really neat, these are mistakes even veterans sometimes end up making, specially when coding for too long 🙂

Great Information about useEffect hook, every React developers should know about this. I would prefer to use async/await function to make an API calls. I observed that - It suspends the function when It makes an API call and waits for the result then continues with remaining lines of that async function but it won't stop the execution during the async function suspended, it continues to run with other statements and it calls back the suspended function once the calls stack is empty and results are available from the API call

Why project with firebase and react slower on web compared to firebase with flutter any answers

@eshw23 Год назад

Hey Pedro! I was wondering if you can make a MERN tutorial in the near future, just like you made a React and firebase project.

why the string "Updating" in console only occur once at 5:10? According to the strict mode at 3:58, it should execute twice .

Hello pedro Im on a project right now. I Creating a CRUD but i need to refresh the page to refetch the data, how can I make the table realtime? Im using react, Node, Mysql

@JohanDG7 Год назад

Not sure if I understand your problem but: Fetch the data again right after you added new data.

@kurniamassidik5798 Год назад

Can i ask something sir ? Why people prefer choose promise then try and catch, thanks before.

@PedroTechnologies Год назад

I wouldn’t say that people in general prefer one or the other. I feel like since promises was the standard first, a lot of projects already use it, so it wouldn’t make sense to change. I personally go with whatever my company is using, unless im writing my own project, which in that case i use async await and try catches

useQuery in common cases is over engineering

@EdwinManual Год назад

It’s not.

@anass.codes1 Год назад

@@EdwinManual Well, it may not be necessary for every project but stills a great easy tool to use if you want to satisfy some complex requirements on the way you fetch data, that's why I think that using it for such simple use cases is not what it's meant to be

@EdwinManual Год назад

@@anass.codes1 For devs who think fetching data from API can be implemented using JS fetch may think React Query as an overkill. But most of the time when you are building a REAL MODERN APP you need to take care of few other things as well everytime you do an API call. Such as loading state, error state, refecthing and cache invalidation etc. I am not saying these all other things are not possible without React Query but you can save a lot of time and your sanity if you use React Query. If you don't care about above mentioned features while doing API calls. You don't even need React in the first place. Because you are building web apps just feels like they are from the PHP5 era.
