You should give a hint that the left-panned audio in the intro will resolve later on or people might jump ship :D

Thank you Laith for the great content once again. I had to buy the Udemy course so I can the advanced parts.

[afamsval]

You are the best Sir. Thank you for always using typescript in most of your projects

[syedalishahbukhari]

Awesome 👍. Please make a course on TypeOrm

[abdullahh.abdulazim]

Good stuff Laith, wanna suggest that you consider adding a mongoDB/nest mongoose with GraphQL as an additional section in your Udemy course, that would be great!

[leanprogrammer]

Great stuff. The amount of content you provide on here is ridiculous! How are you so productive???

[GabrielGasp]

Hey Laith, just letting you know that there is a YouTube channel named Voxmind with your udemy NestJS course (and a bunch of courses from other people). You might wanna do something about that.

Love this video, bought the course on udemy too. Anyone know how are he is formatting lines like @2:36:35 ?? I know on Mac it's shift+option+F by default to 'format' but is that all that's happening? Thank you for all your great teaching Laith!

[saadowain]

Thanks alot. Will buy the udemy course.

Can we know what are the topics and technologies your are working on ...

[yassineaker]

I'm looking forward for the next big project. Could you let us know when it will be published?

[geelemo]

hello, I'm having an issue where when I throw new HttpException or any type of exception my app stops running and is terminated. Also the response code remains 201. Any help?

[dumpstr]

thanks for the great video, Laith.

Out of curiosity, is there a particular reason you filter AND find a report? Find will return the first report for which the id === the id passed in, so wouldn't it make sense to use either filter (filter by id) or find (by id)? Seems almost redundant.

The only use case I can see for this is when you initially set up your data.ts, if you have two ids that are the same.

Thanks, and again, great job. I love learning from your content.

Example:
```
[ { 'id': 1, 'value': 'yes'}, {'id': 2, 'value': 'no'}, { 'id': 3, 'value': 'yes'} ].filter(report => report['value'] === 'yes').find(report => report.id === 1) will return { 'id': 1, 'value': 'yes'}
[{ 'id': 1, 'value': 'yes'}, {'id': 2, 'value': 'no'}].find(report => report.id === 1) will also return { 'id': 1, 'value': 'yes'} (as will just [...].filter(report => report.id === 1) )

```

Thanks Laith. But I don't see any discount on udemy.

Hy Mate, your videos are really amazing, please also make a video with this (Nest JS, TypeORM, GraphQL and PostgresQL) stack, thank you :)

explaining things like what is request or how REST works in NodeJS framework course is a bit more than harsh :D

[edwardkeselman]

Is there a reason not to use Expose decorator with the name createdAt over created_at property? I tried it and it worked, why do I need to expose a method?

[moylababa]

Please make a microservice tutorial using Node.js

[codernerd]

If only it had one 3rd project with Graphql and Auth to follow up the other course, also does the final project use secure cookies?

[wahebbenzaid]

Nothing to say ! this is a great tutorial, I was waiting for it. By the way, what do you recommand for a nodejs beginner, express or nest ?
