Deploy

npm run deploy
npm run client-deploy # deploy sample hello world from dist folder

You can either put your static assets into the dist folder and run npm run client-deploy to upload them to the S3 bucket, or upload files directly to the <domain> S3 bucket. Route53 and CloudFront will take care of any redirections and content serving for you.
