Run Eslint on production build

[beguene]

Ideally we should allow eslint to be run on production build Currently we have

  eslint: {
    // Warning: Dangerously allow production builds to successfully complete even if
    // your project has ESLint errors.
    ignoreDuringBuilds: true,
  },

Is this related to #759 ? can we consolidate the work of Eslint in an issue?

It's not exactly the same but this #730 needs #759 to be done first.
