Andrew Scott from the Angular team discussed Angular without zone.js. Various content authors published videos about topics like Signals for forms.
Andrew Scott on zoneless
TechStackNation runs sessions with members of the Angular team quite often. This time, it was Andrew Scott, and the discussion evolved around removing zone.js, which landed in Angular 18 in an experimental mode. Zone.js triggers the change detection where Angular updates the DOM.
Andrew told us a little about the trade-offs. On the one hand, zone.js does everything for us in terms of change detection and is reliable. On the other hand, it could be more performant. Signals are a very good fit here because they can trigger Change Detection and point it to the right components.
Some might ask if Signals should always be used when representing values in a template. We got a very clear answer.
Andrew also touched on zoneless testing. We should use the whenStable() function of the ComponentFixture and not rely on zone-based functions like fakeAsync().
Another discussed topic was the relationship between the Angular and the TypeScript language server.
