是否可以使用通配符从目录中的所有文件导入模块？ [英] Is it possible to import modules from all files in a directory, using a wildcard?

问题描述

使用ES6，我可以从这样的文件中导入几个导出：

With ES6, I can import several exports from a file like this:

import {ThingA, ThingB, ThingC} from 'lib/things';

但是，我喜欢组织每个文件有一个模块。我最终得到这样的导入：

However, I like the organization of having one module per file. I end up with imports like this:

import ThingA from 'lib/things/ThingA';
import ThingB from 'lib/things/ThingB';
import ThingC from 'lib/things/ThingC';

我希望能够做到这一点：

I would love to be able to do this:

import {ThingA, ThingB, ThingC} from 'lib/things/*';

或类似的东西，理解的约定是每个文件包含一个默认导出，并且每个模块都被命名和它的文件一样。

or something similar, with the understood convention that each file contains one default export, and each module is named the same as its file.

这可能吗？

推荐答案

我不认为这是可能的，但是模块名称的解析取决于模块加载器，所以可能有一个加载器实现支持这个。

I don't think this is possible, but afaik the resolution of module names is up to module loaders so there might a loader implementation that does support this.

在此之前，你可以在 lib / things / index.js 中使用一个中间的模块文件，它只包含

Until then, you could use an intermediate "module file" at lib/things/index.js that just contains

export * from 'ThingA';
export * from 'ThingB';
export * from 'ThingC';

并允许你这样做

import {ThingA, ThingB, ThingC} from 'lib/things';
