This is a short journal, but NullInjectorError: No provider for _HttpClient! was resolved when I used module-based approach. I already imported HttpClientModule (this is for HttpClient used to call an API) in app.component.ts, which is a standalone component referenced in app.component.ts using bootstrapApplication. With module-based approach, the import not happens at module level (app.module.ts). For some reason, the error was resolved.
