Essence
Essentially, it is a system application package, and the commands are its core components.
As shown above, you can run the HTTP service using gower run.
In other words, the HTTP service is just one of the commands.
Command Mode Packaging
The command mode is a simplified mode because if everything is packaged, running the gower command would generate some log and temporary files in the directory, which is not what we want.
Therefore, the command mode removes services such as route, logger, and db.
$ go install -tags cli
or
$ go build -tags cli
