Question

我有一个带有全局常量的文件，我正在尝试将其导入另一个js文件，以便可以在其代码中使用常量。

globalConstant.js

"dependencies": {
    "@angular/animations": "^6.0.3",
    "@angular/common": "^6.0.3",
    "@angular/compiler": "^6.0.3",
    "@angular/core": "^6.0.3",

  }

我想在我的webpack.config.js中使用这些全局变量

webpack.config.js

            "styles": [
              "src/styles.css",
              "./node_modules/bootstrap/dist/css/bootstrap.min.css",
              "./node_modules/font-awesome/css/font-awesome.css",
              "./node_modules/tempusdominus-bootstrap-4/build/css/tempusdominus-bootstrap-4.css"
            ],
            "scripts": [
              "./node_modules/jquery/dist/jquery.min.js",
              "./node_modules/popper.js/dist/umd/popper.min.js",
              "./node_modules/bootstrap/dist/js/bootstrap.min.js",
              "./node_modules/moment/min/moment.min.js",
              "./node_modules/tempusdominus-bootstrap-4/build/js/tempusdominus-bootstrap-4.js"
            ]

但是它的构建给了我错误：

global.RoutesOffersPage =  {
  routes: [
    { url: '/fr',
      title: "page daccueil france"
    },
    { url:'/fr/dothis',
      title: "trop sympa"
    }

  ]
}
global.RoutesActionPage =  {
  routes: [    
    { url: '/fr/action',
      title: 'page d'action'
    }
  ]
}
export { global.RoutesOffersPage }; 
export { global.RoutesActionPage };

我通常会在有函数的时候知道如何导入，但是这里只是常量'global.constants'。我迷路了。

由于使用了webpack，因此可以使用import，但是由于webpack不会递归捆绑其自身的设置，因此无法在webpack配置中使用它。您必须回去那里：

require('./globalConstant.js');

global.RoutesOfferPage/*...*/

Webpack-仅导入具有全局常量的文件
