Vapor is a modular framework built for a modular language. Code is split up into modules which are grouped to form packages. Packages can be added to your project by adding the package's Git url to your Package.swift file. Once a package is included, all of its modules will be available to import. You can read more about packages and modules in the Swift Package Manager conceptual overview.

Below is a list of packages and modules that come with or can be used by Vapor projects. Packages will have a link to their respective GitHub page.
