Angular app not running

Hi All,

I am trying to run an angular application in cloud9.  The repository from Github that I forked can be found here.

I should be able to run the application in cloud 9 with the below command according to the author who has a course on pluralsight that I'm following.
ng serve -o

Open in new window

When I run it, I get the following
Angular Error
When I click on localhost:8080, it's not recognized.
not recognized

It seems working fine in your local. Open the browser and type http://localhost:8080

I think the problem might have to do with a path. In that dir structure screenshot, your app.js file is in the src folder, but the public folder is up one level from there. The app.use statement can't see it when it not responding the visit the site give the suggestion.

If you see the notes at github it says that this plugin requires angular varsion 4.3 or higher.First check the path and then the angular version

Is the browser running on the same sever as the one you ran ng serve on?

The report from the build process is good - so there should be a node instance listening on 8080 that you can connect to - but you will only be able to connect locally - you cannot connect from your host computer.

It does not work for me in http://localhost:8080

I'm not sure if Angular is using a different port.  This is all new to me

Here's what I get for path and angular version.  It says undefined.
ang version
Julian HansenCommented:
ng serve is reporting it is running on 8080 (usually defaults to 4200)
you can try
ng serve --port 4200 and then try to connect on localhost:4200

I need to check though - where is your browser running - is this on your local machine or on

It can only work if the browser is running on the same physical machine as the one you ran ng serve on - it is no use opening a local browser and trying to connect - it won't work.
IsaacSharePoint Client Side DeveloperAuthor Commented:
It's running on my local machine.
Julian HansenCommented:
It's running on my local machine.
Do you mean the browser?
And your angular project is running on

If that is the case it is never going to work. localhost refers to your local machine so the ng serve needs to be running locally as well - is this the case? I don't suspect so or you would probably not be having this problem.
IsaacSharePoint Client Side DeveloperAuthor Commented:
Yes, it's the browser.  It makes sense what you are saying.  But it has to run in angular and I think it can....check this out  I think there is some configuration settings I need to do.
Julian HansenCommented:
That thread does not seem relevant to this issue.

You are wanting to connect to the Angular instance running on C9 using a local (to your computer) browser connecting on localhost - which is not possible (using localhost) if the browser and angular code are not physically on the same machine.
