To fix this error:
Property 'ngOnInit' is missing in type 'BookDownloadModalComponent' but required in type 'OnInit'.
Make sure the order and naming is correct. Don't use OnInit, but ngOnInit. An example of my book-download-modal-component.ts:
import {Component, OnInit} from '@angular/core';
import {Book} from '../../../../../core/models/book';
@Component({
selector: 'app-book-download-modal',
templateUrl: './book-download-modal.component.html',
})
export class BookDownloadModalComponent implements OnInit {
@Input() book!: Book;
constructor(
) {
}
// make sure this is AFTER the constructor
ngOnInit() {
console.log(this.book);
}
}
