AngularJS Question

Angular2 version RC.6 "directives" inside @Componnet Error

I am using Angular2 and have downloaded package.json from official website. When I am trying to use "directives" inside @Component decorator I am getting error.

I have attached my code ERROR:

[ts]
Argument of type '{ selector: string; template: string; directives: string;
}' is not assignable to parameter of type 'ComponentMetadataType'.

Object literal may only specific known properties, and 'directives' does not
exist in type 'ComponentMetadataType'.
(property) directives: string


This is my code:

import { Component } from '@angular/core';
import { PeopleListComponent } from './people-list/people-list.component';

@Component({
selector: 'my-app',
template: '<h1>{{ title }}</h1>',
directives: '' //ERROR //NOT ABLE TO RECOGNIZE
})

export class AppComponent {
title = "My title";
}


Here is my package.json:

"version": "1.0.0",
"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",

Answer

simple...

problem is with directives: ''

as its an array it should be directives: [ ]

update: In rc6, you must have @NgModule. In RC6, you have to declare pipes and directives that you are gonna use within @NgModule as shown...

import { PeopleListComponent } from './people-list/people-list.component';

@NgModule({
  imports:      [ BrowserModule],
  declarations: [ AppComponent,PeopleListComponent ],  //<----here
  providers:    [],      
  bootstrap:    [ AppComponent ]
})

You can remove directives:'' from @Component of AppComponent
