@reliverse/rse-sdk/bin/providers/better-t-stack/utils/get-package-manager.js

@reliverse/rse-sdk allows you to create new plugins for @reliverse/rse CLI, interact with reliverse.org, and even extend your own CLI functionality (you may also try @reliverse/dler-sdk for this case).

export const getUserPkgManager = () => {
  const userAgent = process.env.npm_config_user_agent;
  if (userAgent?.startsWith("pnpm")) {
    return "pnpm";
  }
  if (userAgent?.startsWith("bun")) {
    return "bun";
  }
  return "npm";
};
