Your channel is ridiculously helpful. I always feel jacked to get into my angular projects after watching a few of your videos

[@MonsterlessonsAcademy]

Glad to help!

You're welcome

[@KushanShanuka]

while watching this, i feel angular signals feature is seems like vue refs.
by the way you explained well. thank you

[@botondvasvari5758]

what if there are more complex filters that can come from different components ?

[@MonsterlessonsAcademy]

Then you need to change your code acording to requirements.

[@denysbilas3670]

HI! Thanx for sharing! I want ask you about architecture for front end application. What architecture do you use for your pet projects or work?

[@MonsterlessonsAcademy]

Typically by feature architectured like I showed here th-cam.com/video/IFTqfO_evlc/w-d-xo.html

[@jorgen180]

What is recommended approach to implementing custom input field validation while using Signals? Functionality provided in Reactive Forms doesn't yet seem to be reflected to Signals.

[@MonsterlessonsAcademy]

I don't use signals for custom validation. Just plain reactive form

[@dimitridoroshko]

Hey, man. What is your favorite framework out of the top three: angular, react, Vue?

[@MonsterlessonsAcademy]

I don't really like one of them more then others. Most importantly for me is to get paid for any of them. My personal preference is Elm but unfortunately it is not that popular.

[@christopheradolphe]

Hi Oleksandr, thank you for this great tutorial about Angular signals. I've read some articles over the web about when to use signals vs observables. Some of them advise to keep using observables in services and use signals in components. Your video clearly shows that a service can entirely work with signals. I'd really like to know what are your thoughts about this. Also what's that code editor you are using ?

[@MonsterlessonsAcademy]

I see zero reasons to use something in either service or comp. Don't read these articles :)
Use signals for simple state. Use RxJS when you need RxJS methods like distincUntilChanged, etc

[@christopheradolphe]

@@MonsterlessonsAcademy Thank you for your response and the great content!

[@4444-c4s]

🙏🙌

[@moegreen8543]

Are there already any standards (generally accepted rules) for writing variable names for signals?

[@MonsterlessonsAcademy]

Nope. It's wild west.

[@AdelBasiony]

can you please make a video using singals and Ngrx together in a project. Thanks.

[@MonsterlessonsAcademy]

I will add it to the list of ideas. Thanks

[@USONOFAV]

ok so Signal is just an alternative to rxJS Subject?

[@MonsterlessonsAcademy]

Partially yes

[@felixmatusinio6438]

If we will use signal, do we still need rxjs? to be honest rxjs is quite pain in the ass.

[@MonsterlessonsAcademy]

I have a video about it
th-cam.com/video/WL7QEhdqh00/w-d-xo.htmlsi=h3BmPJld15fBJV1s

[@jerrytab4276]

combine rxjs and signals

[@AdelBasiony]

Isn't it better to move all computed signals to the service and just call them in the component? even if the signal is used once in a single component.
I'm really confused about which is the best practice.
Highly appreciate your videos.

[@MonsterlessonsAcademy]

Sure. If it is shareable than move it to comp. If not then not.

[@AdelBasiony]

Thanks a lot.@@MonsterlessonsAcademy
