Exciting news! Angular Voices of Asia is here – the first remote Angular conference spotlighting the amazing community across Asia! 🥳

Experience in-depth technical sessions, and connect with the Asian Angular community

🔗 Join us: angular-voices.asia

#AngularVoicesAsia #Angular #AsianDevelopers

Keeping up with the rapid pace of #AI is tough. I went from VSCode to a #Cursor license, moved on to #ClaudeCode, and now I'm back on Cursor - this time with #ChatGPT 5. What’s next, #Gemini 3?

At least the light theme lives on. Imagine someone invents a "dark mode". God forbid 😅

[New Article] All about DDD for Frontend Architectures (with Angular & Co.)

It’s always good to have someone looking over your shoulder…
Though having the "Gigantic @younesjd.dev" behind you is slightly intimidating 😄

Greetings from ng-Rome!
📸 Thanks to @martinakraus11.bsky.social for the picture.

YouTube video by Rainer Hahnekamp NgRx SignalStore Events

My new video on the @ngrx.io SignalStore Events plugin is live! 🎬

It covers common use cases, like:
✅ Decoupling logic
✅ Cross-store communication

Also dubbed in multiple languages — including (ironically) German 🙃

RxJS & Native Observables: A Direct Comparison
🔁 78-min deep dive:
1️⃣ RxJS implementation
2️⃣ Native equivalent
🧠 Also a great way to refresh your #RxJS skills (error handling, share, teardown, etc.)

I'm happy to be part of this. Together with @rainerhahnekamp.bsky.social I will do our Angular Architecture workshop there. Big thanks to the organizers for bringing back this epic conference – it marked the beginning of so many friendships and careers back then!

Gave a talk this Monday on unit testing in #Angular - basics, mocking, async tasks, and more!

Slides (with repo link) are here:

Big thanks to @angular-community.bsky.social for organizing!

🐢 In a few hours I’ll be speaking at the @angular-community.bsky.social Meetup series on testing — and yes, the official theme is Turtle Power!

I’m covering:
✔️ Basics
✔️ Async
✔️ Mocks & fakes

💥 Cover by ChatGPT might be overkill, but I stand by the tests 😄

Here are the slides from my talk on Micro Frontends in #Angular (including source code), which I gave at Ng-India last week

Finally, huge respect to @dhananjay7.bsky.social for running this conference with such dedication, even in the face of occasional headwinds.

Marko Stanimirović previewed the upcoming events (Redux) feature for @ngrx.io SignalStore at #ngIndia

🚀 Could land by end of April
🔁 Unifies global + component state

My take: The current SignalStore handles most global states fine, mainly smoothing the transition from the classic Global Store.

Thanks so much for the shout-out – and for joining!

httpResource is NOT a replacement for HttpClient

It’s designed for reactive fetching (Signal-driven) and runs on top of HttpClient.

For mutations, HttpClient is your friend.

YouTube video by Rainer Hahnekamp Accessibility Testing with Playwright

I mostly cover NgRx, Architecture & Testing - not accessibility. But my latest video is a blend of #Playwright & #A11y! See how easy it is to integrate different a11y aspects into your tests. 🚀

Btw, I made sure the cover is fully a11y compliant 😅

🔥 Pretty nice week for #Angular
📽️ The docu was great, and 19.2 brings big updates for resource & friends
📡 resource emits multiple values (WebSockets, SSE, GraphQL, SignalR)
🛠️ Initial value built-in—no manual workarounds
🌍 httpResource PR landed, hope it makes 19.2
