motivation

In a monorepo, multiple projects need to share the configuration, instead of each project writing its own command line parameters or configuration file, which is actually annoying, it would be nice if there was a way to specify the configuration via a simple option

• Support shared configuration, in json or command line parameters, it is recommended to configure in package.json
• backing config is a function that returns a config option or a Promise<Config>

Existing program

The eslint approach is through the extends option, ref: https://eslint.org/docs/latest/user-guide/configuring/configuration-files#adding-shared-settings
prettier can directly point to a package, ref: https://prettier.io/docs/en/configuration.html#sharing-configurations

If you'd like to include this functionality, I'm willing to implement it
