Great video! What about 'array' and fields that can be added dynamically? Do you planning to create video to cover this part of Reactive Forms? Also, it would be great to hear about 'setValue' and 'patchValue'. Maybe some more advanced parts of this amazing topic.

Wow, just as I am building a Reactive Form as we speak! It is like you are a mind reader! Thank you! I'm struggling w/ valueChanges. How do I use valuechanges w/o subscribing?

Just thought you need that :) You use valueChanges just like a normal stream - you can subscribe, combine, etc

Thank you!
how do you hide the error when you complete the field correctly? I mean when click the button submitted is true, so when you complete the field correctly it will show the red border and the message error

You can reset submitted to false after any field change
Thank u for the video. My thoughts: 1) hardcoding a certain error message in the template doesn't seem to be a flexible approach. 2) tracking by yourself whether the form is submitted inside the component also doesn't seem right. Doesn't FormGroup instance provide this information? If not, what a shame.

Ok, may be there was no other choice. Angular just provides errors like {required: true} or {minlength: {actuallength: ..., ... }}. What an ugly design omg.

No Angular doesn't provide the info if the form is already submitted
The angular already handle classes to the inputs like ng-dirty, ng-touched or ng-invalid.

Shouldn't we unsubscribe from valueChanges?
@MonsterlessonsAcademy
11 ай бұрын
Usually it's a good practice to imperatively unsubscribe if you imperatively subscribed. It can also be that garbage collection does not immediately dispose of the component instance and then it might still receive some events util it's finally gone. The subscribe callbacks might cause errors when the component is not alive anymore or might cause expensive operations (network request) that are not necessary anymore when the component is disposed.
Wait. I thought you retired because of ChatGPT?

Почему видеоролики не на русском??(это не претензия кстати но мне интересно почему, думаю если бы они были на русском ты бы собирал очень много просмотров так как контент реально годный и на русскоязычном ютубе очень мало такого)
