there's at least one guy i know of on github whose claim to fame is he finds code in existing node codebases by big corpos that's duplicated, breaks it out into a library, then PRs the original codebase with "instead of doing manually, switch to depending on this library", then adds to his profile "my code is used by ". he had thousands of libraries like that last i checked, most of them less than ten lines of code. the manifest and other boilerplate is way larger than the actual code.
