[英]how to export 2 different functions from one js file into another Js file in Protractor
[英]Creating service library in JavaScript, how to export functions from one file in another?
所以我在身份服务中有这个代码。
export function sumbitLogin(username, password) {
console.log(username, password);
}
因此,无需在每个组件中导入我需要的每项服务,我希望能够只导入一个服务库,让我的组件可以访问它需要的每项服务。
所以我创建了一个 js 库文件,它只包含
export * as Identity from "./identity-service";
这样我就可以从我的组件中导入该文件作为
import * as Services from '../../services/service-library';
它似乎没有接受这个,因为它给了我这个错误
./src/services/service-library.js 1:9
Module parse failed: Unexpected token (1:9)
File was processed with these loaders:
* ./node_modules/babel-loader/lib/index.js
* ./node_modules/eslint-loader/dist/cjs.js
You may need an additional loader to handle the result of these loaders.
> export * as Identity from "./identity-service";
我尝试了 10 种不同的方式导出它,但我永远无法达到submitLogin()
。 有谁看到我错过了什么? 我觉得另一个装载机是不必要的,但如果不是,我不知道我需要哪个装载机?
更好的方法是在services文件夹中创建一个index.js文件,您可以在其中重新导出所有服务:
import * as Identity from './identity-service';
import * as Logger from './logger-service';
...
export {
Identity,
Logger,
};
然后您可以直接使用该文件:
import * as Services from '../services';
const { Identity, Logger } = Services;
Identity.sumbitLogin(username, password);
