JavaScript 在对象中导入而不是要求

Question

假设我有这样的代码：

module.exports = {
  Someclass: require('./lib/Someclass')
}

我可以让它更像 es6

export default {
  Someclass: require('./lib/Someclass')
}

但是我如何在不设置变量的情况下将 require 替换为 es6 语法？提前致谢

Answer 1

您可能不应该默认导出对象，而应改用命名导出。所以要么

// re-export the whole namespace
import * as Someclass from './lib/Someclass';
export { Someclass }

或

// re-export the default export
export { default as Someclass } from './lib/Someclass';

Answer 2

MDN lists 聚合模块的以下模式：

export * from './lib/Someclass' // does not set the default export
export * as name1 from './lib/Someclass'
export { name1, name2, …, nameN } from './lib/Someclass'
export { import1 as name1, import2 as name2, …, nameN } from './lib/Someclass'
export { default } from './lib/Someclass'

JavaScript 在对象中导入而不是要求

JavaScript import instead of require in an object
