Execution of npm scripts follows this syntax: npm run <command> [-- <args>].

In your case, this is: npm run start --first-argument first or using the shorthand for the start script npm start --first-argument first. Mind that the part in brackets is optional.

This is the according PR from 2014 which enhanced npm to enable this. Also, this question already been answered.
