Standalone packages

The packages are specifically meant for the development of SuperMQ based back-end applications and implement common tasks needed by the programmatic operation of the SuperMQ platform.

Using the packages

Fetch any package directly from the module:

go get github.com/absmach/supermq/pkg/authn
