在单独的文件中创建typerscript类并在angular2组件中使用它们

export class MyClass {
  private name: string;

  constructor(name: string) {
    this.name = name;
  }

  public getName(): string {
    return this.name;
  }
}

import { Component } from '@angular/core';
import { MyClass } from './my-class';

@Component({
  selector: 'app-root',
  template: `
    <h1>{{ myClassInstance.getName() }}</h1>
  `
})
export class AppComponent {
  public myClassInstance: MyClass;

  constructor() {
    this.myClassInstance = new MyClass('John');
  }
}
