angular2全局变量

angular

使用Object.freeze来使属性成为真实的常量。可参考 es6-const。

// global.ts
export const GlobalVariable = Object.freeze({
    BASE_API_URL: 'https://orchome.com/',
    //... more of your variables
});

使用import引用模块。

//anotherfile.ts that refers to global constants
import { GlobalVariable } from './path/global';

export class HeroService {
    private baseApiUrl = GlobalVariable.BASE_API_URL;

    //... more code
}
