Work has expected
https://github.com/ggaulard/nx-remix-react-native (conf file)
mixing nx, remix and react native to have a common ui component library
(require some npm i --force, waiting react native release to support react 18)

Working as expected from my Nx monorepo with RemixJS using libraries, this is my remix.config:

/**
 * @type {import('@remix-run/dev').AppConfig}
 */
module.exports = {
  ignoredRouteFiles: ['**/.*'],
  watchPaths: [
    '../../libs/**/*',
  ],
};

Thanks for your help folks, Remix live-reload is amazing now! <3
