Edit with Angular-CLI 1.0.0

You can now directly define the used port in the .angular-cli.json file by defining the property like this:

{
    "defaults": {
"styleExt": "scss",
"component": {},
        "serve": {
            "port": 3000
        }
    }
}
Here is a direct link to all available options for the configuration: Angular-CLI options configuration

You can configure it directly in your packages.json, change your start scripts by:

"start": "ng serve --port 2500",
And then run your server with npm start


this will override the .angular.cli.json file. app will run in 2500 port.

You can also try with this to run your application in visual studio code -:

ng serve --open --port 4201

you can give any port number. 

*** It will in open in default browser. e.g I.E edge in windows or your preferred browser.
