  externals-esm-loose is a master directory that gathers 3 subdirectories: node_modules, pages and test.
  At the main level, 'node_modules' comprises 4 packages: esm-package1, esm-package2, esm-package3, preact.
  Within directory hierarchy 'node_modules > esm-package1', Inside 'esm-package1', you'll find it hasn't been filled with any content.
  At level 2, in directory path 'node_modules > esm-package2', The 'esm-package2' folder is blank.
  Within directory hierarchy 'node_modules / esm-package3', Inside 'esm-package3', you'll find it is blank.
  Within directory hierarchy 'node_modules / preact', The 'preact' container hasn't been filled with any content.
  At the main level, 'pages' hasn't been filled with any content.
  At the top level, The 'test' compartment has been left empty.
