How do I dynamically grab all of the files in a folder within a src folder in webpack? For example, say I have a directory structure like this:

src/
  packages/
    package.js
    file-a.js
    file-b.js
    file-c.js

I want to call all the file-*.js files from the packages folder at once. Right now, package.js looks like this:

export * from './file-a.js'
export * from './file-b.js'
export * from './file-c.js'

How do I dynamically export all of the file-*.js files from package.js, without having to go in and add a new line every time I add a new file.js file?
