Looking for way to copy files in gulp and rename based on parent directory

Not the answer, but applicable to this question's appearance in search results.

To copy files/folders in gulp

gulp.task('copy', () => gulp
  .src('index.js')
  .pipe(gulp.dest('dist'))
);

The best way is to configure your base when sourcing files, like so:

gulp.src('./client/src/modules/**/index.js', {base: './client/src/modules'})
  .pipe(gulp.dest('./build/public/js/'));

This tells gulp to use the modules directory as the starting point for determining relative paths.

(Also, you can use /**/*.js if you want to include all JS files...)

return gulp.src('./client/src/modules/(.*)/index.js')  
  .pipe(gulp.dest('./build/public/js/$1'));

Worked for me !
