Can Zone.js be fully disabled when using signals?
Yes, it can.
Signals track changes and update the template without Zone.js. Angular can now work fully reactively, without a "zone" that used to intercept all events and trigger updates manually.
How it is done:
In main.ts, at application startup, you specify:
ts
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app/app.component';
bootstrapApplication(AppComponent, {
zone: 'noop', // disables Zone.js
});What happens next:
- everything based on
signal,computed, andeffectkeeps working; - Angular will update only the parts of the template that depend on signals;
- no "zones" are needed anymore.
Summary: yes, signals let you fully disable Zone.js, and the application still stays reactive and updates itself.
