The workspace is the root directory in a Polylith codebase, and it's where we work with all our building blocks and projects. A workspace is usually version controlled in a monorepo, and its subdirectories looks like this:
▾ workspace▸ bases▸ components▸ development▸ projects
If you want to see an example of a complete Polylith codebase, go to the RealWorld example app.
