How to dynamically render different Angular components with unique @Input() and @Output()...

    I'm building a dynamic UI engine in Angular (v15+) where I need to load different components at runtime based on configuration. These components each have different @Input() and @Output() properties.

    What I'm trying to achieve:

    Render multiple dynamic components using ViewContainerRef.createComponent()

    Bind @Input() values dynamically (even though each component has different inputs)

    Subscribe to @Output() events generically

    Cleanly destroy or replace components when needed

    const componentConfigs = [
    {
    component: ButtonComponent,
    inputs: { label: 'Click Me' },
    outputs: { clicked: () => alert('Button clicked') },
    },
    {
    component: CardComponent,
    inputs: { title: 'Card Title', content: 'Lorem ipsum' },
    outputs: { selected: data => console.log(data) },
    },
    ];

    loadComponent(config) {
    const componentRef = this.container.createComponent(config.component);

    // How to set `@Input()` and bind `@Output()` safely?
    }


    My Questions:

    How can I dynamically bind arbitrary @Input() and @Output() properties using createComponent()?

    Is there a type-safe or generic way to handle components with different input/output contracts?

    What's the best practice for cleaning up subscriptions from @Output() when destroying components?

    This seems like a common requirement in CMS-style systems or dynamic form builders. Most examples show how to dynamically load one static component, but I’m looking for a flexible pattern that supports many components with unique bindings.
