angular signals link not working

@zebcode 9 месяцев назад

Angular signals link doesn't work?

@Brendan2Alexander Год назад

Simple video but all I needed to get bopping with signals. Thank u!

@ancientelevator9 Год назад

Love the naming; super intuitive!

@yufgyug3735 Год назад

Great stuff, will update my applications as soon as it is production ready!

@Angular Год назад

Yes! What's a problem this syntax solves for you?

@yufgyug3735 Год назад

@@Angular i imagine using far fewer async pipes thanks to signals

@indylawi5021 Год назад

Thx for the info. Looking forward to using Signals. Glad Angular is moving in this direction.

Angular Signals: A reactive approach, with features from Vue and React combined !

@brampeirsful Год назад

FYI: Signals link not working.

@Angular Год назад

Sorry, try this out: angular.io/guide/signals

@VoyageofLittleLiya 11 месяцев назад

Please explain real time implementation of signals and computed with their pros & cons.

@compton8301 Год назад

Interesting. Thank you.

@its_vincesanity Год назад

I'm not sure if I understand it correctly: Is the goal to go away from the "classic" 2-way-binding approach? That would be a bummer

@rickelmonoggin Год назад

yes, it's going to change: inputs and outputs will be implemented with signals, not with decorators; but it will be backwards compatible so old code won't break when you update Angular.

@its_vincesanity Год назад

@@rickelmonoggin thanks for your answer, but I meant more about in general. If we still with have two-way-binding or a React-like concept for Angular as whole.

@mugatu2017 Год назад

spending time learning ngrx, rxjs , reactive forms,...for nothing, thanks angular

@Angular Год назад

Signals will be interoperable with RxJS and we haven't finalized the Reactive Forms story just yet. We're also working with library authors on this stuff, too! So your hard work isn't all for nothing :)

@sjk9128 9 месяцев назад

Somehow, I’m more comfortable with rxjs than signals, only feature I didn’t like in ng is depending on ngOnchange instead reactive inputs.

@jophilmadrigal6154 9 месяцев назад

signal component will solve this problem

@jonno081 2 месяца назад

Is signal similar to ref in Vue and effect similar to Vue's watch?

@powerbit Год назад

Good ,Thanks.

@amirmehrizi6045 Год назад

the core concept is derived from the React useState and useEffect hook to update the DOM.

@marcel5235 Год назад

not the concept but DX, under the hood there is no VDOM or working loop, it uses shadow dom and render pipelines ( in theory this can be faster than VDOM ), signals are inspired more by Solid than React

@mac.ignacio Год назад

hahaha don't push the react concept on Angular. It will never suffice. Angular doesnt have a VDom. REACT is not REACTIVE. REACT has a false reactivity concept.

@Nafiganado 8 месяцев назад

What are the alternatives to mimic this approach in Angular 15?

@vedantmandwe5326 Год назад

@techduke9511 Год назад

Angular team, how can i upgrade my angular application from version 12 to v.15, in between i facing lots of dependency conflicts ?

How to call a function on signal change. Effect is one function, how we know which signal changed thatswhy effect called.

@SkillnoMusic Год назад

"When the value of the signal they USE change"

@Mego4884 Год назад

When you defined function effect( () => { signal1(); signal2(); } ) then effect( () => { signal1(); signal3(); } ) - so when signal2 is updated, then the first effect function will be called, when signal3 is updated then the second effect will be called. When signal1 is updated - then both effect will be called. I hope I got it right :)

@nathanalberg Год назад

sweet

@FelixKirchhoff-je9pq Месяц назад

thats heavily influenced by solid.js signals.

@yuriimarshalofficial Год назад

takeUntilDestroy and signals - when you use own framework and tired to type all that spaghetti (me too) 😄 that's what I call user friendly! Guys you are brilliant!

@mac.ignacio Год назад

ReactJS is not reactive.

@shashankvivek4812 Год назад

Why so many major changes all the time? 1st from Angular Js to Angular 2 , which shook confidence of consumer who put money in Angular Js. Now we will have libraries with old way and signal way. Doesn't boost my confidence with these Fancy stuffs .

@Mego4884 Год назад

This is not breaking change, this is just optional feature which you can use for your benefits. But it's also perfectly fine to do as you are used to :)

@shashankvivek4812 Год назад

@@Mego4884 I agree but I think it would be more confusing for new devs to understand both approach. Angular already requires steep learning curve. I have been working on angular since 2016 , and I feel that it is gonna solve important problem but will bring more complexity with 2 diff approaches. All libs will start releasing 2 versions now. That's what I don't like

@Cheesyonmytoasty Год назад

It’s the angular way, it gets frustrating. Looks like a load of extra boiler plate to add more dev work where I thought Angular should be letting us code and sort out the updates to UI behind the scenes 🙄

angular is digging his own grave

@xXxDiukexXx Год назад

Why do you think that?

@Simon-yf7fo Год назад

Yea, I'd love to know that as well. Seems like a great change and no one forces you to use signals. If you dislike them just stick to rxjs

@JBuchmann Год назад

I think it's a great addition. Forever people complained about the Zone.js change detection being slow, inefficient, etc. I think Signals is their way to resolve that problem.

@avivbenshahar6422 Год назад

It is a good solution and a pretty nice feature. The thing our friend here meant was that Angular core code base became so huge, that it’s almost impossible for a new developer to learn it all 😕 That’s why breaking changes should not be avoided.
