    Angular: Will lifecycle methods soon be deprecated? How to replace them? - Stack Overflow

    programmeradmin4浏览0评论

    I heard the rumor that the lifecycle methods of angular are going to be deprecated. Is this true? Can someone provide a valid source?

    How can I replace them?

    • ngOnChanges() -> Input-Signals
    • ngOnInit() -> ?
    • ngOnDestroy() -> ?
    • ngAfterViewInit() -> ?
    • ngAfterContentInit() -> ?

    There is no deprecation is sight, but it is a reality that new APIs might be a better fit that the lifecycle hooks.

    I recently wrote about it and did a talk on this.

    ngOnInit/ngOnChanges can be replaced by signal based reactivity depending on the exact usecase (derivation via computed/linkedSignal/resource) or effect()/afterRenderEffect()

    The "after" hooks, ngAfterViewInit/ngAfterViewChecked/ngAfterContentInit /ngAfterContentChecked can be replaced by afterNextRender()/afterRender().

    ngOnDestroy has had an alternative for a bit longer with DestroyRef.onDestroy().
