Any good resources on steps to upgrade to application builder in v17 without upgrading to v18/v19?

Quick question: do you think about a class getter as "derived state"?

Did you know you can create #Angular template-driven form groups? Defining forms is easy even without reactive if you know the details. You can use `ngModelGroup` to achieve the same result:

Another just-for-fun question So, the #RxJS `tap` operator is specifically designed to perform side-effects However, its implementation is just taking an Observable and returning a new one with the side-effect slapped on it So, is `tap` itself a pure function or not? 😁

What concepts from reactive programming do you find the most challenging to explain to beginners? My bet is on "declarative programming"

#NgRx ESLint ruleset has a rule that prohibits mapping Observables from the store to be mapped in component Instead, it encourages the use of new, derived selectors and a direct selection of the state I believe we should not create computed properties from store signals What do you think?

My last article seems to be doing quite some rounds... If you have missed something from Angular v19, check the article out - there are a lot of hidden gems there! www.angularspace.com/angular-v19-...

When we make HTTP calls in #Angular, sometimes we need to map the response to something else With `rxResource`, would you prefer to do it with an #RxJS operator, or with a computed/linked signal? I prefer doing it with RxJS, but I want to hear opinions

I ran into an #Angular article today, and I think it is entirely AI-generated The amount of just plain wrong stuff in it is too astounding to write it off as just a mistake Honestly, this makes me mad medium.com/@sehban.alam...

Important to remember: while `Resource` implements some methods from `WritableSignal` (set, update), it is not itself a signal. If you want to bind a resource to `ngModel` in your #Angular component template, use its `value` signal, not the resource itself:

I never understood why people would make Facades for #NgRx, I don't get the point. Isn't NgRx itself already a facade? A big, complex system with which you interact only via two simple methods (dispatch, select)

You can call methods of a child component in #Angular templates via a reference variable Do you think this is a bad practice? If so, how can we avoid it? What would be some cases where this is justified?

Not something super hard, but important #Angular linked signals have the same scheduling approach for computations as regular `computed` properties Computation does not run initially until the value is first read. Subsequently, only new reads will trigger to recompute

I've run into an interesting type issue with #Angular's new `linkedSignal` Using the previous value argument in computation callback results in an `unknown` type, even when the type returned is super explicit Any idea why this is the case?

My upcoming #Angular v19 article is already under review, and I'm happy to say exploring the full release docs taught me a lot Interesting things are coming 🤫

What have been some cases, in your experience, where you purposefully did not use `OnPush` in an #Angular component? Was the component too large? Did it cause many issues? I'm interested in hearing scenarios

I think one improvement to #Angular's Resource API would be the addition of initial values Sometimes the `request` can depend on optional signals, and we might want an easier mechanism of having some default value:

#Angular's Resource API is wonderful Easily chain HTTP requests that depend on each other:

I'm already writing a new article I will cover all the more obscure features (some of them I already tweeted about) that got a bit overlooked because of the `linkedSignal`/Resource API hype 😁 Will drop next week! 🚀

#Angular v19 Resolvers will now also accept a `RedirectCommand`! We can use it to navigate to other pages depending on the data received, or for handling errors

Let's maybe start an #Angular discussion? What's the best feature in your opinion in v19?

If you don't know, I've authored a book about #Angular - aptly titled "Modern Angular" It is approaching print publication and is already available online with early access You can check it out here: www.manning.com/books/modern...

Great to see so much appreciation!

I put a lot of effort into this article - and I mean a lot! I've read the source code, compiled and tried out examples - to deliver you the latest we know about Resource API Give it a read to learn more!

By the way, if you want to update an #Angular signal of an array using an index, the new `Array.with` method can be useful! It returns a new array instead of modifying the existing one, which is perfect for pure updater functions like `update` callback or reducers:

You will be able to provide a `debugName` for signals in #Angular v19 This will become super useful when rich signal debugging tools become available!

The new syntactic sugar for app initializer functions is nice!

I just updated my personal website 😁

Aside from the main points: I love the way #Angular introduces new major versions now. Livestreams are cool and @marktechson.com is amazing!!!

Man, hydration related content is lost on me. Never had a real chance to use SSR on a large-scale app yet

Wait, reordering material tabs? We kinda skimmed through it, but it's a great feature, I guess

I didn't know about `mat.theme` before this livestream, but it seems amazing! Can't wait to check it out

Hah, the `resource` API is introduced with no mention of RxJS and `rxResource` I think it's good, examples look more generic

Today I was thinking that maybe in the future, when #RxJS is made optional the #Angular CLI is gonna ask "Do you want to add RxJS to your project?" when creating a new application 😁

What is the ideal maximum length of a single file #Angular component? I try to limit mine to 120 lines of code, but I have seen more extreme approaches. What do you prefer?

Did you know that instead of untracking multiple signals individually in a computed/effect, you can use an untracked callback? The `untrack` function from #Angular call also accepts a callback, and any signal read in the callback won't be tracked. We can also return the value from `untracked`!

Make sure not to miss the #Angular v19 releas livestream! goo.gle/angular-v19

Do #Angular signals feel like more or less magic than the Zone-based CD that we have?

Lmao my entire feed here is cats... which is not bad at all! 😁 But, we gotta make this more #Angular 😉

Looking forward to #Angular v19 this week... ...to be able to drop the new big article on `resource`/`rxResource` 😉

For what it's worth, here is my latest article :)

I'm interested in talking to #Angular devs here too; Should I just start posting the same stuff I do on Twitter here? 😁

I'm gonna start posting here too

Well, this place looks empty...
