如何从Angular导入中删除.js后缀

Question

我想从Angular导入中删除.js后缀。

不想要（现在可以使用）： import { Example } from './whatever/example.js';

通缉： import { Example } from './whatever/example';

我怀疑我错过了systemjs.config.js中的配置。

(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': '/node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

      // angular bundles
      // other libraries

    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

尝试在包中添加：

'.': {
    defaultJSExtensions: 'js'
}

这样的包现在看起来像：

// packages tells the System loader how to load when no filename and/or no extension
packages: {
'.': {
    defaultJSExtensions: 'js'
},
app: {
    defaultExtension: 'js'
},
rxjs: {
    defaultExtension: 'js'
    }
}
