var glob = require('glob')
var path = require('path')

var entries = {}
glob.sync("./src/**/entry.js").map(function(file) {
  entries[file] = file
})

module.exports = {
  entry: entries,
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name].js'
  }
}

Hey, thanks for this antique gist.
I had to tweak a bit as this as I was using path with ../.
It was outputing in a parent of output.

const entries = {}
glob.sync("../parent-directory/*.js").map(function(file) {
    // be sure to remove path and only keep filename as entryPoint key	
    const entryKey = path.basename(file, '.js');
    entries[entryKey] = file;
})
