I've just recently been introduced to Cloud9. It's a great dev tool. I'm going through the ng-book/Complete guide to Angular 7. I created an HTML 5 workspace, installed angular/cli and verified that npm/node are installed. I've created a simple Helloworld app but I can't get the Ng4 application to run. I can preview the index.html, but none of the data bindings are functionality. It is just rendering the page. I've done "ng build", followed by "ng serve"...but I can't preview the running application. I've also run "netstat" to see the binding...I see 127.0.0.1:8080 & 0.0.0.0:* - not sure where/how to configure the ip/port changes within Cloud9 project. Can somebody point me in the right direction? Thank you!
