Express JS Mistakes Every Junior Developer should Avoid | clean-code

[@theyioel]

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

[@axelandru9346]

Thanks for valuable insights into server security !!!

[@spastheghost]

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.

[@gamingwolf3385]

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]

error.message also works fine

[@logicalimmanuel2357]

thx, concise but pretty informative.

[@fikriahmadfauzi-eb8sj]

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

[@lop3242]

clear and valuable !! thanks a lot

[@seghirissam2662]

Which theme do you use in vscode ?

[@emee__]

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]

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

[@emee__]

@@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

[@mudziahutama7787]

THANK YOU SO0 MUCH BUIDDY !!!!!! VERY VERY important !!!!1

[@imfad3d]

This is really very useful.

[@jamestacular]

After adding the errorHandler middleware your "bad" route is still going to get caught in the error middleware

[@giahuyo4023]

what is theme color you are using bro

[@-ajrego-4869]

ayu mirage i think

[@daphenomenalz4100]

Zod is better imo tho for validation 👀

[@mohammadjawad5085]

Merci

[@CodingGarden]

😄

[@zlackbiro]

Professionals use ZOD for validation!!!

[@perelium-x]

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

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

Good day greetings

Only NestJS ❤❤

[@gamingwolf3385]

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

[@nishaindesilva3738]

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

[@yashinox5410]

If you like a OOP you should try it.

[@coder_one]

​@@yashinox5410OOP in JS sucks...

[@codewithahk]

Say A Bottle of water🤣

[@Maks-fc7kv]

Actually in this case there is only 1 mistake - using such a ****** like express.

[@adamnauka7803]

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

[@mikedev4673]

Good catch, its a bug

[@internetexplorer7880]

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]

@@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]

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