* ```ts
* class ComponentWithProviders {
* constructor(private greeter: GreeterDE) {}
*
* static ɵcmp = defineComponent({
* type: ComponentWithProviders,
* selectors: [['component-with-providers']],
* factory: () => new ComponentWithProviders(directiveInject(GreeterDE as any)),
* decls: 1,
* vars: 1,
* template: function(fs: RenderFlags, ctx: ComponentWithProviders) {
* if (fs & RenderFlags.Create) {
* ɵɵtext(0);
* }
* if (fs & RenderFlags.Update) {
* ɵɵtextInterpolate(ctx.greeter.greet());
* }
* },
* features: [ProvidersFeature([GreeterDE])]
