Best way to work with composer and local modules or packages

I'm working on Yii 2 project.

I try to split a project in to packages.

Now I have done with

yii2-core that a core that require yii2 base project.
yii2-starter that require core and another packages.
yii2-auth my package
yii2-group my package
yii2-page my package

So problem is when I want to implement my packages I do this in my yii2- starter

"repositories": [
    {
        "type": "vcs",
        "url": "/path/to/the/local/git/repository"
    }
],
"require": {
    :
    "my/group": "dev-master"
},

That work but I think it not the best way to do this, Because it will have a lot of commit when I coding and testing this packages.
