Thanks for valuable insights into server security !!!

These tips can be applied in general, not just Express. Thanks for your time. Honorable mention to Flask.

Good one but I don't see a link to the CORS video. It would be helpful for future watchers if you add it to the description.

i want to ask, about the error handling, if its a async function, how to handle it? because the middleware seems cant handle that with throw

@gamingwolf3385 10 ай бұрын

In the part of error handling you can extract the name and code of the erro const {name,code}=error This will help in writing better custom error messages

@akashambrose 10 ай бұрын

error.message also works fine

Bro I know this might seem selfish to ask, but can you make a video on how to migrate express to next js or at the very least how to use express with next js.

@naimurrahman9979 10 ай бұрын

Why do you need express to use in Next js, in api route, you can do the backend stuff without express

@emee__ 10 ай бұрын

@@naimurrahman9979 Most of my application business logic code is already in express. Am contemplating using react with next or ejs for the frontend for ssr

Zod is better imo tho for validation 👀

@muhammadarsallanshahab6760 9 ай бұрын

Brother i think there is a issue with your Mic i can't watch your video full because it hurts my ear the Mic sound sounds just like scratching in board with nails. I do want to watch the video but my ears just can't handle the mic sound

Professionals use ZOD for validation!!!

@SkySentry7 3 ай бұрын

Zod is a great choice if you're looking for a simple and performant validation library that can handle basic validation scenarios. Joi is a good choice if you need a highly customizable validation library that can handle complex validation scenarios

Only NestJS ❤❤

@gamingwolf3385 10 ай бұрын

Nestjs is better than express but it has less community , less tutorials

@nishaindesilva3738 10 ай бұрын

Is there is nestJs ? I always thought its was spelling mistake for nextJs

const statusCode = res.statusCode !== 200 ? res.statusCode : 500 I don't get this line, if 200 we assign 500? Can you expalin?

@mikedev4673 10 ай бұрын

Good catch, its a bug

@internetexplorer7880 10 ай бұрын

When you throw an error you should not send a 200 statuscode to the client so if there's any scenario where res.status is 200 during an error, it will default it to 500

@mikedev4673 10 ай бұрын

@@internetexplorer7880by your logic this line doesn’t make sense if the status code is 201 it will send 201 and 3** will send 3** which it used for redirects and so on.

@adamnauka7803 10 ай бұрын

@@mikedev4673 I think the same. Anyway maybe it would be better to call always 500 in case of error?
