The SmartModule Hub offers ready-to-use packages for easy Fluvio pipeline construction, letting users focus on business logic. It provides tested modules with high-level configurable inputs, supporting a mix of Hub packages and custom SmartModules without requiring module rebuilds.

A view of available and installed SmartModules is accessible from both the fluvio cli.

The list command shows Smartmodules by group/package@version in the SMARTMODULE column. The Visibility column describes if the package is accessible to public or private views. If package visibility is private only your user login can list or download the package. Packages uploaded by InfinyOn will be in the infinyon group.

$ fluvio hub smartmodule list 

  SMARTMODULE                  Visibility 
  mypriv/foo-priv@0.1.1        private    
  infinyon/jolt@0.1.0          public     
  infinyon/json-sql@0.1.0      public     
  infinyon/regex-filter@0.1.0  public

SmartModule Packages are listed in the hub as in the form of <group>/<package name>@version.

Packages in the infinyon group are published by InfinyOn, the creators of Fluvio. Third-party developers can upload public packages under different groups. The Hub enforces signing and publishing restrictions on uploaded packages. Once a signed package is published in a group, only the group owner can update it or add new packages within that group.

By default, published packages are private. To make a package public, set it to public using the following CLI commands:

cd smartmodule-dev-dir
smdk set-public

Once set to public, you’ll be prompted for verification on every publish. Note that once a package version is publicly published, it cannot be revoked.
