Feature Request

  • I would like to work on this feature!

Is your feature request related to a problem? Please describe.
I'm currently building some tooling for a monorepo. In here, I want to build each package as CommonJS and ES modules. Therefore, I want to be able to add parameters to caller argument, so I can detect which target I should build for.

I want to have a single babel.config.js file, where I can react to these arguments in the config:

const supportsESM = caller => {
  return !!(caller?.name === "my-awesome-tool" || caller?.useESModules);

Describe the solution you'd like
Add a --caller option to @babel/cli.

Describe alternatives you've considered
I've considered building something like gulp-babel and/or babel-loader, but I don't want to maintain all that logic.

Teachability, Documentation, Adoption, Migration Strategy
They will use this through the CLI. This would provide more flexibility in terms of calling the CLI with caller options.
