This series is gold. Literally worth it and no other tutorial out there in any paid course. Thanks a lot.

[@chaiaurcode]

Great to hear!

[@RhythmAlgo]

I saw multiple KZbin videos on express or backend related or even talked with multiple people for the last 1.5 years, but no-one has ever told me about the api response and api error thing. 46 mins worth it.. Thank you so much ❤️

[@chaiaurcode]

Kaafi standard approach h, almost hr badi company ke project me hoti hi h

[@RhythmAlgo]

@@chaiaurcode Okay sir. Ak aur chota request tha, iss wale series mai Microsoft authentication (majority KZbin mai google and other authentication hai but koi Microsoft account authentication cover nhi kiya hai) cover kr lena please. Although mai neh documents pad ke implement kiya hai and working bhi hai, but production level wala sikhna hai sir

Quick note to help understand asyncHandler-thanks, ChatGPT! 😄 What is asyncHandler? asyncHandler is a higher-order function. A higher-order function is a function that takes another function as an argument and possibly returns a new function. Why is asyncHandler needed? In Express.js, if an asynchronous function throws an error, you need to explicitly pass that error to the next function for the Express error-handling middleware to catch it. Without this, your server might crash or not handle the error properly. Different Variations Version 1: The normal function const asyncHandler = () => {}; This is a simple function Version 2: The higher-order function const asyncHandler = (func) => { return () => {}; }; Takes a function (func) as an argument. Returns a new function. Version 3: The higher-order async function const asyncHandler = (func) => { return async () => {}; }; Same as above, but the returned function is asynchronous (async). Used when the inner function (func) involves asynchronous operations.

The lecture was Hard, because its new to us . very deep understanding . GOD Level. I enjoyed a lot Because this is production level . Thanks sir for such a wonderful and interesting lecture.

[@subhassssadhu]

Today, it was a great session in backend where middlewares and api errors/responses were handled. Some parts were tricky and would require some more efforts from the side of the students and it will be fun to put that input as an exercise. Thanks sir for such a great lecture.

[@vipinishere9679]

i have enough knowledge of backend development but it was little bit difficult to understand for me because these things are industry-level and good practices as well. thanks for such awesome content.

[@sanskaripatrick7191]

33:05 I'm pretty sure that there is a mistake in the asyncHandler that uses the promise (the top function). There should be no curly braces after the arrow otherwise there wouldn't be a value returned at all -> and that is because we haven't written an explicit return statement. The correct code is to either include a return statement before the internal arrow function or to just remove the curly braces, although adding a return statement makes it a bit easier to understand.

[@mohd.maasir8198]

thanks I was also having doubt there.

[@ofy_naveen9973]

next(err): If an error occurs (the catch block is triggered), next(err) is called with the err argument. This signals to Express that an error occurred, so it should skip all regular middleware functions and proceed directly to error-handling middleware.
