npm packages are not found - SyntaxError: Unexpected token '<'
By default Istio will proxy from https://dev.myDomain.com/base-app/npm.babel.4fca5....chunk.js to http://pod_ip:8000/base-app/npm.babel.4fca5....chunk.js, and, as far as I can tell, your image serves files directly from /dist, so Istio should actually proxy to http://pod_ip:8000/npm.babel.4fca5....chunk.js; note the missing /base-app/. To do that, try to update the Istio Virtual Service to:
- match: - uri: prefix: /base-app rewrite: uri: / route: - destination: host: svc-app port: number: 8000
