To make a subpackage with dub; follow these general guidelines.

General guidelines

1. Create a new folder.
2. Open the folder.
3. Initialise a new package. (dub init)
4. Open dub.json file
   • Append this:

     "subPackages": [
      "./component1/"
     ]
     

5. Create a new inner folder named component1
6. Initialise a new package inside the inner folder (dub init)
7. Open the previous package folder.
8. Run the subpackage as a test. (dub run :component1)

This is how it is made in Windows 10:
(I use Windows 10, please excuse for not giving Linux directions.)

"subPackages": [
	"./component1/"
]

Just a side note, you can also supply a name to init directly and it creates the directory etc:

dub init myproject
