[@suhailchouhan6467]

Hello Hitesh Sir, I wanted to express my gratitude for the amazing content you've been providing. I recently began learning backend through your videos and it's been an incredible experience. 1. Regarding the code you mentioned at 20:33, there's a handy shorthand we can utilize to fix the error using optional chaining. By using the following line of code, we can resolve the issue: const coverImageLocalPath = res?.files?.coverImage?.[0]?.path This shorthand allows us to apply optional chaining on arrays as well. Once again, thank you for your guidance! 2. If a user is already exist then the temp file will not be removed as multer runs a middle ware and if a user already exist then we directly throw an error but not removing the files from the temp folder.

[@sujeetrath9630]

can you share solution for 2nd point how can you delete the files if user exist

[@adamyasharma_0135]

[@jenilmangukiya525]

Great Video ❤ I have two Question 1 ) why are we passing two different status "201" in status Code and "200" in response body return res.status(201).json( new ApiResponse(200, createdUser, "User registered Successfully") ) 2) Why are we throwing error in response instead of error can we pass an response with error message? or we are going to build this in future?

[@tipssedlife]

1) both 200 and 201 indicates successfull responses Generally 200 ( OK ) status code is used for successful resquest. 201 ( created ) status code is used when the request is fulfilled and result in the creation of new response. These code are industry standards , but you can use any status code between 200 and 299. Sir, explained these things in HTTP headers crash course, please refer that. 2) Yes, you can pass an error with a response like : return res.status(400).json({ error : "error occurred"})

[@meet2960]

Yes, i do have same doubt with the error message that we should use the res.status() and json() with the ApiError class to send our API error's as a response. Maybe it will be very helpful in Frontend side i guess. Correct me if i am wrong. Thankyou

[@adityabharti1826]

such indepth content is hardly available anywhere . Loving this series sir

[@Error404Codes]

​If we do not provide the any field property in the request body from the client, the code will proceed without error so i think it might be great to apply as if ([username, fullName, email, password].some(field =>field ===undefined || field?.trim() === "")) { throw new ApiError(400, "All field are required !!"); }

[@AbhishekChoudhary-p1h]

I encountered two unexpected errors during my project, but I managed to resolve them. Sharing this in case it helps someone else: 1) When using the .env file for sensitive information like a secret key, I initially masked it using asterisks (***********). However, this caused an 'Invalid Signature' error. The fix was to ensure the secret key not in asterisks format. 2) I faced issues while setting up the MONGODB_URI. Adding the query parameters ?retryWrites=true&w=majority resulted in an error, preventing the creation of my database collection. Removing these parameters resolved the issue. Hope this insight saves someone else valuable time and frustration! Thank you for sharing your experiences.

[@atharvarolkar6236]

Thank you bro. I was getting the Invalid Signature error. Go to see I have set the secret same as api key.
