Month: January 2025

As usual, we’re using the 3-2-1 format of the newsletter this week. I’m posting a few essential articles to revisit, updates to know about, and one question to ponder:

Three articles to revisit:

• Content projection is an essential and easy technique to create reusable components. For more complex scenarios, you can also use multi-slot content projection, and if you want a full conference workshop recording on that topic, we have that video from ng-conf 2022.

Two Angular updates:

• The Angular team announced its priorities for 2025: Signal forms, RFC for selectorless components (meaning no more imports needed for components !), promote zoneless to developer preview, and replace Karma for unit testing.
• Our FREE monthly online workshop is scheduled for this Thursday, don’t forget to register now. I’ll talk about different simple strategies to migrate from RxJs to Signals in Angular.

One question to think about:

• Signals are stable, with the exception of the effect function. Since Angular is going all in on Signals, with Signal forms being next in the pipeline, have you started migrating your apps to use Signals instead of RxJs? Attend our next free workshop to see me do it live.

This week, we’re using the 3-2-1 format of the newsletter once more. I’m posting a few essential articles to revisit, updates to know about, and one question to ponder:

Three short articles to revisit:

• HTTP interceptors can be used in several ways to assist with authentication, refactoring code, caching data, and more! Read more about them with this tutorial.
• Just like guards and resolvers, HTTP interceptors can also be declared as functions.

Two Angular updates:

• Angular 19.1 is now available! The most interesting addition is a new CLI command to automatically clean-up unused imports: ng g @angular/core:cleanup-unused-imports
• Another interesting update is the support for Typescript 5.7 added to Angular 19.1. More info about Typescript 5.7 here.

One question to think about:

• Do you call methods in your Angular component templates sometimes? If so, check this out to consider a better alternative.

Happy New Year! Let’s get back to the 3-2-1 format of the newsletter. I’m posting a few essential articles to revisit, updates to know about, and one question to ponder – all good knowledge to kickstart 2025 the right way:

Three short articles to revisit:

• Change detection is a tricky topic that keeps evolving as Angular gets better. To get the right mental model of how it works, you can check these posts on change detection illustrated, what markForCheck() is and does, and finally tie this all together by understanding how the async pipe and Signals trigger change detection automatically for us.

Two Angular updates/announcements:

• Angular v20 will be released during the week of May 19th 2025.
• My next FREE online workshop is scheduled for January 23rd, and you can register here. I’ll cover techniques and best practices to migrate to Angular Signals:
  

One question to think about:

Did you know that you don’t always need pipes to format dates or numbers? You can use the functions used by the Angular pipes directly in TypeScript instead.
