Migrating your project to AWS IOT device sdk v2

Its all fine, good read but when we do ng-build getting issues it says - pub-sub-test.component.ts depends on 'aws-iot-device-sdk-v2'. CommonJS or AMD dependencies can cause optimization bailouts. For more info see: https :// angular.io guide/ build#configuring-commonjs-dependencies

so how to use sdk and build properly ?
