About The Channel
The knowledge that I share here is mostly from my personal experiences. I wouldn't say I'm a 20 year professional, rather I am just a DevOps / Software Engineer with a lot of experience who enjoys teaching what I know in my spare time. I believe that sharing some of my basic knowledge on this platform can help others get started. There are many ways to program something and the videos you see here are my take on the NodeJS / Typescript / and sometimes Unity world. If this channel helps you learn, or helps you think differently then my job is done 😊.

The perfect tutorial I've been looking for! Not just teaching the technologies but most especially best practices, testing, and error handling! Thank you! Make more videos please! Subscribed!

[@mallorylaforet6419]

Glad you're making videos again. I enjoy your content!

[@TheOnlyIchiban]

This is seriously a fantastic tutorial, i love the in depth explanations on what you're doing and the reasons, it's really important to understand. This was exactly what I needed, awesome work

[@AndrewEddie]

Great update. I shot you a pull request that shows you how to use the Rest Client plugin available in VSCode as an alternative to Postman. Also happy to do an example for project based snippets if you are interested (you could, as a silly example, set up a snippet to give you boiler-plate code for any middleware function).

[@TheNerdyCanuck]

I like that a lot! Looks really easy to define some routing tests (instead of postman) I think I'll merge it in for people to try. As for snippets, I'm saving those for other videos as things get more complex.

[@AndrewEddie]

@@TheNerdyCanuck thanks for that!

[@JacquesOP]

Thank you Sir that was exactly what I was looking for. Simple and educative!

[@beetpalm]

i love it, i'm from thailand I'm just starting to learn how to program. I really enjoy your videos.

[@lukaslearning3549]

I hope you will cover Jest as well. I tried it before but I got trouble with type-checking inside test files.

[@TheNerdyCanuck]

I am working on some test stuff now

Thanks a lot for providing such a quality content

[@pdsavard]

Thanks for the great video. Got a small question, in the Cors Middleware, I can't add the return res.status(200).json({}) without getting a typescript error on the application.use(corsMiddleware). error: No Overload matches this call... Any idea?

[@TheNerdyCanuck]

No overload matches makes me assume the function itself isn't defined properly. Still having this issue?

[@pdsavard]

@@TheNerdyCanuck solved! its because in typescript I can't do return res.status(200)...... something do not like that. I need to set the status then do a "empty" return;

[@TheNerdyCanuck]

@@pdsavard strange, it should let you return but I'm happy you got it to work!

[@SayfSentinel]

This way better than a Netflix series

[@TheNerdyCanuck]

Appreciate that

[@daz1uk]

Great video 👍

[@aliahmadi8816]

@TheNerdyCanuck Thank you for the content, I get an error if i try to log any of the config variables, I have to import them individually for it to work, what i mean is doing: import './config/config'; console.log(DEVELOPMENT) will throw an error that Cannot find name 'DEVELOPMENT Thank you!

[@TheNerdyCanuck]

Its a setting in the config file to check the NODE_ENV env var

[@trieunguyentuan4589]

why using package cors. Thanks

[@TheNerdyCanuck]

You can use a package for it for sure, it's probably easier

[@attaullahsiddiqui3931]

Why are you not making more videos?

[@TheNerdyCanuck]

I would like to make more! I am working on some testing ones right now, it's just hard to justify the time with the kids atm :)

[@attaullahsiddiqui3931]

@@TheNerdyCanuck Cool. Plz make more vidoes on NodeJS Angular GraphQL

[@atnguyen-qg6ze]

Why can logging be used in handlelogging middleware?

[@TheNerdyCanuck]

The middleware is designed to add logging to every request instead of using a third party library.
