So nice of you.. and happy diwali 🪔
watching this video after diwali , but happy diwali sir.
25:00 We don't need to remove the locally saved temporary file if the upload fails, as keeping the file can be useful for retrying the upload. Only delete the local file after a successful upload.
confident feel kar rha hu abhi se ❤❤
This is going to be epic. Happy diwali Sir in advance.
Happy Holi Sir and all

sir if it is possible then make a video on how to use redis in an application
sir comment o gya .. thanks for this video ..
High quality content indeed, when i started my journey 2 years ago, i was not able to find this type of quality content and learned the hard way. For people who do not have time to study everything via docs, these tutorials are diamond and really really good, i wish i had got this much content when i was learning all these stuffs, but it is still the best feeling when you do stuff yourself without any tut, everyone should try learning themselves first before watching any tutorial (imo).
Please keep up this good work, its highly appreciated ❤.
(Happy diwali ❤) i hope everyone can achieve success in their life and hitesh sir a long lifespan ❤.
ram ram sir...........happy diwali
Happy Diwali Sir, Sorry for late wish but I always prefer watching any playlist once it gets completed so that I don't need to wait for upcoming videos😅😅❣❣

#ChaiAurCode , Thankyou sir for providing this quality content..
great level of teching sirji

storing files - aws , third party like cloudinary, multer or express-file upload
how to handle file upload : seperate utility function or using middleware not using in controllers
same code for img, video, pdf
Cloudinary : "4:33" "8:42"
files from user ---multer--> localStorage-->Cloudinary "10:38" 2 steps setting why?
file system (fs) in node: "14:20" -open , read ,
unlink : "15:15" & "24:22"
cloudinary : "18:20"
multer as middleware for specific routes : "27:50"
multer.diskstorage(destinatioin, filename)
function (req,file,cb){cb(null, //write your logic)}
destination: function (req,file,cb){cb(null,"./public/location")}
filename:function (req,file,cb){cb(null,file.originalname// use date for unique)}
Happy Diwali sirrr
Thank you sir for this amazing series. I understand what being in the zone means. And these `charcha` takes us to that zone of learning. Amazing series. Keep it up!!! Happy Diwali everyone
The best video
32:20 The file path here is './public/temp'... I guess it will store the file in the current directory, that is "middleware" folder.
Shouldn't we write '/public/temp' ?
yes i agree

🤍Dil garden garden ho gya sir se backend Phadkar ! 🤍
Awesome Content ❤❤❤
Very Informative video, I am just having one doubt incase we have uploaded media files/images directly to cloud eg AWS S3 (post validating on frontend instead of doing it on backend) then we can save a lot of bandwidth/time/cost assuming we have lot of users on website and they can also upload images of good quality eg 5MB average size. In case someone can add related usecases will be better to know. Thanks
Happy Diwali Sir 🎉 🪔🪔🎇🎇🎇🎇
Haapy holi sir for advance
Happy Diwali sir🎉
Happy Diwali sir ji🪔🪔🪔🪔🪔🪔🪔
Happy deepawali sir
दिवाली की हार्दिक हार्दिक शुभकामनाय सर आप भी ज्ञान का दीपक हमारे लिए जलाये राखीयेगा 💗
24:53 we unlink the file in catch block....but if the file is not uploaded in the cloudinary then why we are removing it from the temp folder... instead shouldnt we delete the file when the upload is done ?
Happy Diwali 🎉🎉 sir
thankyou sir
diwali ki ram ram ❤ late hai but ram ram toh jb karo tbhi achha hai
why was `fs.unlinkSync()` used instead of `fs.unlink()`? Wouldn't it be better to use an asynchronous( `unlink()` ) function to delete a file so that it would not block the event loop on the server?
Happy Diwali, Sir❤.
Happy diwali 🪔
Happy Diwali Sir Ji
Back to backend again. This time not going anywhere until I complete this.
