how to check if three.js is already installed in the dist folder and not install it again if installed already in the project

Not sure I'm following your question - if three.js is a peer dependency of your package, it should not be included in your distributable.

Consumers of your package will need to assure they've installed three.js in their projects.

Dependency resolution is a responsibility of applications that use your project.

bundles three.js but in many cases a site using it will already have their own three.js - is it possible to fix this so it doesn't bundle three.js into the dist bundle?

so this is how the question originally is

Your package should not include three.js in the distributable.
