Migrations inside composer scripts

I would like auto start migrations when "composer require ..." and "composer update". Not manual.
The composer allows to do this. For example:
https://getcomposer.org/doc/articles/scr...hp-scripts

But the command "spark migrate -all" can be called in the ROOTPATH. How can i call this from project root path?

The another way (similar to spark migrate) is to call controller method like this:
spark install index
spark update index

And this is the same question - how to call from root.



The way is to create own spark file in the package root. And then we can call it something like this:

Code:

    "scripts": {
        "post-package-install": [
            "@composer run-migrations"
        ],
        "run-migrations": [
            "@php spark -install -index"
        ]
    }

And how can we pass execution from our package spark to default /project-root-path/spark?
