From the beginning when you explained the situation I thought you were going to use debouncing. Learned something new today, keep it up! Going to use this in my next application 👍🏻❤️
I personally use keyDebounce i.e a custom function which sends request to backend only when the user pauses to type for approx of 300-400ms. In this way not only the network conjunction is reduced but also reduces the number of requests to backed. (sending a request and cancelling it is more complex than just not sending it)
You can use useEffect hook which will react whenever the search Term changes and you can give 1 sec time using setTimeout to allow to the user to type. if the user types next word within 1 sec then we have to return cleartimeout of the previous one and set again and if the user stops for a second or more then that means user has typed the word and you have to fetch the data then. This is optimized approach I believe.
this is really worth watching, so many things we don't know as fresher and getting info at the exact time when you needed it is a boon. Thanks for sharing :)
Hitesh bhai! Hands up! Was searching for this kind of solution since long time. It can also be used to ensure current response is represented on UI in case the response of second request comes before the response of first request! Got me?
12:40 for actual modifying of api calls to fix the unnecessary api requests made by the standard "on search term change -> initiate api request" implementation
No doubt today I have learned new things in this video. Thanks a lot for sharing with us. we can also use denouncing or throttling for problem statement mentioned in video.
What if we store all the data which came from the server in first request into an array and then if user enters the second word the data should be searched from that array instead of going again to the server.
Imagine having millions of records, however your way isn't totally wrong depends purely on usecase such as: Doing this on amazon where you have millions of products - terrible idea Doing on a webpage of an instructor such as hitesh and searching among hundreds of his courses - yes.
is it a good practice to set a timeout of 1s or so in the useEffect and clearing the timeout in the cleanup to execute the API hit? basically waiting for 1s for the user input, if we didnt receive any input we'll execute the axios part else clear the timeout and again wait for a second. is this a good approach for the search!? Thanks in advance :-)
16:40 the problem is everyone creating content for newbies. I know most of the viewers are beginners but I think you should produce more advanced topics. Thanks btw.
By this way request are only cacelled from browser. It will still get processed by server. So no network load reduction on server side. Only an illusion on browser. for this use case we can use debouncing.
I usually defer on usecase like this with timeout and cancelling previous timer, axios cancelToken is new to me thanks for the intro.. However I fell just cancelling a request from front end might still cause unnecessary load to server, since by the time we cancel this request the request might have already reached server and server is already in the process of querying data ...
I Have seen a very good video about debounced function on Akshay saini channel. during his flipkart interview intreviewer ask him to design same like this one.
What I got from this is, it can cancel previous requests if they arent completed. So this doesn't make much difference in case of a very high speed internet. I'd still prefer debouncing using setTimeout fir this particular scenario.
In the product in which I work, we run an interval of 300ms, if any change is detected within 300ms, we cancel the request, if no changes made within 300ms, a request will be made.
Great Tutorial. However my question is why can't we implement something using setTimeout so that we make request only when user has stopped typing? Would love to hear your thoughts on this approach
Why you haven't used onChange={(e)=>onType} as I understand if you don't use callback it will call Every rerender Correct me if I am wrong ..and reply me if you are agree with me Hitesh
I didn't understand how it is going to reduce load on server. Coz server has already received request and will be processing it. Its the frontend who doesn't want results right?
No it's async request.. while processing first request if user makes another one then canceltToken avoids it to send second request on to server until gets the result of first🔥
I understand the usecase but can it also not be achieved by just putting a delay before making a request (which would also reduce the load on the server + client's traffic). We can wait for some amount of time (may be some hundred milliseconds) before firing the api call and we fire the api call only after the said amount of time interval from the last on-change event (last time the user entered something).
It would be very awesome if we could get a course on production-grade applications

Yes I too use denounce if there is not any submit button

I use this approach too
I think we can also use denouncing functionality to follow same approach, it would make code much more cleaner and easy to understand.
we all code... but most of us donno to do it the right way.. Tqs for this content... Looking forward for many more videos like this sir..

@Hitesh Choudhary Good to see you back, loved the video.. The intro was great
Hitesh bhai! Hands up! Was searching for this kind of solution since long time. It can also be used to ensure current response is represented on UI in case the response of second request comes before the response of first request! Got me?
I was actually finding a solution how to do this. Finally got this.
Netflix style intro🔥, If the font had some other colours too it would have been more cooler
This Thumbnail is DOPE⚡
A out of the box feature which I didn't know about, very informative. Typically we use debouncing or throttling depending on the use case.
The only TH-cam channel I turned on the notification🔔
I also did kind of the same thing couple of days back, but by using 'debouncing', another cool concept.
Stephen grinder course ?? 🌝
Pretty dope Netflix type intro🔥🔥🔥... Keep uploading such content 😁.
if not using axois to fetch data then can use debouncing basically which adds a setTimeout() method to a given operation

Thank you for this amazing video. Waiting for more this type of video🙏🏻
Your thumbnail are pretty good and also content
It's quite simple to understand, thanks for sharing and looks forward for your amazing videos. Love it 😍
In this particular case we can even use denouncing which will help us to avoid flood of requests
We can also debounce the request for further optimization.
Ohh, That *NETFLIX* introduction 👍👍👍👍
How about using a debounced function which triggers the API call?
Of course, that’s another great solution
Hey Hitesh, Which one among these would you consider the most optimal?
@@dineshwinchester9599use both
Pardon my newbie knowledge of React but why did you use typepf at 13:50 at line 9 when if (cancelToken) was sufficient.
Great tutorial, 😎👍!!, what i like to is, check if the user typed at least 3 characters in the input field, then i send the 'http request'...
A fabulous point to discuss ❤️
I prefer to use debounce in that kind of scenario
good use case is a package for flutter which can handle the scenario
What if we store all the data which came from the server in first request into an array and then if user enters the second word the data should be searched from that array instead of going again to the server.
You'd be storing some details which the user would never end up wanting. So not really optimal.
Imagine having millions of records, however your way isn't totally wrong depends purely on usecase such as:
Doing this on amazon where you have millions of products - terrible idea
Doing on a webpage of an instructor such as hitesh and searching among hundreds of his courses - yes.
Thank you Hitesh for this wonderful missed out feature of axios....😁

It is a good approach. It's called debounced search.
@@fariduzzamaansari1656 ok got it!! Thank u :-)
Take care sir, Content is really Helpfull, Thanks a lot sir :)
Received notification when i was in LearnCodeOnline
just thinking, I WISH I COULD JOIN YOUR TEAM!
Do not you think it would be great if we use Throttling for this case? CancelToken is used when we have huge data (upload) ??
We can also use debounce
We can use debounce instead of cancelToken 👀
Sir Waiting For a Video on your VS Code
How does the canceltoken get sent to the server? Is it added to the querystring in the URL , cookie variables or some HTTP header?
Familier with question? watch from 12:00
Can you please suggest a video on finding all broken links in an application using an app URLs?

you are right. I believe setTimeout with useEffect is better approach.
We could have also used debouncing, so only making requests when user stops while typing for a some time interval.
Man the intro is dope ⭐⭐
I Have seen a very good video about debounced function on Akshay saini channel.

Really helpful content for optimization 👍
Thanks for this video, Great explanation!

Enjoyed guruji🙏🙌
Thanks Got To Learn Something New About Axios But My Question Is Can We Use Throttling Or Debouncing Instead Of Cancel Token To Achieve The Same....
how to apply for job at your startup
edit: I am a fresher and i already knew about this solution, along with this we can also use debouncing
Will you do a followup on this lesson by using useState and effect?
this can also be done with AbortController
Debounce technique can also come to rescue the scenario..
Awesome video. i guess axios internally implements debounce technique for optimization
What do think about denounce? ( lodash ) That would be better solution or not?
what if we type bit slow, can we set min/max time between two letter in search?
Take care of yourself ❤️.
Thankyou soo much
Why can’t you use an on Submit or on Click?
can we use the cancel token with the barrier token or not ??? or with the header in axios
Why you don't use debouncing here.
Thank you sir, and what are your thoughts regarding debouncer in production?
Sir, It is a really awesome tutorial, but sir is it good approach over debouncing?. 🤓
Super work 👌
Very helpful video sir
In the product in which I work, we run an interval of 300ms, if any change is detected within 300ms, we cancel the request, if no changes made within 300ms, a request will be made.

Debouncing is also useful in such cases

Correct me if I am wrong ..and reply me if you are agree with me Hitesh
Hi I was wondering that whether Debouncing is used in production level apps?
Yeah I used debounce in this type of scenario in all production level application that I worked on
so which one is better, cancetoken or debouncing?
What about using denounce Here??
I didn't understand how it is going to reduce load on server. Coz server has already received request and will be processing it. Its the frontend who doesn't want results right?
No it's async request.. while processing first request if user makes another one then canceltToken avoids it to send second request on to server until gets the result of first🔥
@@vaibhavbakal It cancels second request?? or the first request??
Hey which font you are using in vs-code? is it 'fira-code' ?
Thank you so much for this 🙏
What do you think is better cancelling the previous requests or using debouncing?
.....or we can use debouncing
What about debounce or throttling

Thought no video will be released, since March is for Health ryt!
True but I am all fit now and ready to make videos 😁
@@HiteshCodeLab Happy to hear this Sir 😁
Can you prepare laravel course.
Fetch all the courses at first, save it into courses state (hook) and then search keywords from the courses state.. will this approach work sir?
I understand the usecase but can it also not be achieved by just putting a delay before making a request (which would also reduce the load on the server + client's traffic). We can wait for some amount of time (may be some hundred milliseconds) before firing the api call and we fire the api call only after the said amount of time interval from the last on-change event (last time the user entered something).
Sir What is different between this concept and Hooks if I use here..
Is your fav color purple?
We can use deboucing here?
Nice intro! and helpful content :)
Thanks a lot sir 🙏
How about denounced requests?
Could try typescript. It makes understanding code so easy and fix bugs and issues before hand. By the way thanks for cancel Token👍
Good to see again
This is interesting. Are the code files available somewhere? Thanks.
@hitesh Why is GC going to be an issue with the variable?
Great video 🔥!
Can't we just use debouncing to “group” multiple sequential calls in a single one for each keypress using vanilla js (setTimeout) ?
If you can make similar videos for optimization it would be great🔥🔥
