Discussion on: Beyond create-react-app: Why you might want to use Next.js or Gatsby instead

Two questions:

• If we host a next.js app on AWS (instead of on vercel), it seems to me it's a more expensive than hosting a CRA app because it needs lambda@Edge, comparing a simple cloudfront CDN.
• CRA is ready (and almost out-of-box) for PWA, but how much work a next.js app need to do to achieve PWA?
