Getting started with Angular Signals

Introducing Signals, a new reactivity model in Angular. Signals equips you with high quality tools for fine-grained reactivity,
while setting you on a well lit path and providing you with guardrails to make your app performant. Learn how to start exploring the developer preview in Angular v16 today.

The most complicated example to learn signals on the internet

[sravant]

Example should be simple to understand.
Not sure why you choose complex examples.

[shaikhhar]

Its just like behaviourSubject but less verbose. I like it

[PashaSemf]

Exactly how I imagined the people responsible for Angular!

[baris]

the Example Application is pretty complicated. I Joind the other commentators mentioning to use simple Examples to explain the concepts of signals.

[shivappasagar]

loved the way you guys presented effects. Practically

[vukkumsp]

Finally we can use effects in angular without ngrx, like we use with react redux.

[techwithjesus]

You both are here to confuse folks 😂😂. I love how Mark Techson explains this on Frontend Masters. I watched the video because of her.

[marcialabrahantes]

This is their replacement for observables... got it!

[IsuCompare]

as i just started to work with angular again after 2-3 years of pause, i dont quite get the difference between two-way-bindings and signals as you can just pass the value and it will be shown on the UI when updated. other than that using behaviours also would do the job to track on some values, sharing with services is also possible..

[RenanLeandroFerreira]

Can we use signals with forms? How signals will be integrated into Form Builder?

[mxz]

so the main difference to behavioursubjects is, that you dont need the subscribe stuff and you have less sideffects like with multiple subscriptions and chaining pipes on one subject?

[markusingvarsson]

Loved the video! 🥳 a really awesome demo!

[aravindhhere]

How this is different from BehaviourSubject ???

[mohammedasim]

why dont you take very simple example?...

[LogUp-ufth]

like the example provided, the video is equally complicated to decipher! Such examples should not be for the introduction of a concept!

[Ernestas]

Who ever came up with this example idea, did not want for people to fully understand the signals.

[anapaulalopesaraujo]

Is this example really necessary?! No hate, but it is pretty difficult to understand. 😒

[jediampm]

Hi, thanks for the video.
Two things:
- when using stackblitz, please dont use inline template because of missing code highlighting.
- in effect, please dont use var keyword to declare a internal variable. Use const in this case.

Another things that dont see an answer for:
- signals beside replace zone.js, will it replace also ngModel directive or banana in the box ?
- What about forms, mainly template driven forms?

thanks.

My team decide to not update to angular 16 because Signals are still in development mode and not ready yet for production, is that true?
