This library automatically creates an exports map of all/some files in a directory
npm i --save forward-modules
Inside any directory, just add your entry point file, you don't have to name it index.js, you can also name it *.js or all.js.
And just add the following snippet:
module.exports = require('forward-modules')();
You can also exclude some modules:
module.exports = require('forward-modules')([ 'ModuleA', 'ModuleB', ]);
this exposes all modules in the directory except ModuleA, and ModuleB
