Update for @angular/cli@6.x: and over

In the new angular.json you now specify a port per "project"

"projects": {

    "my-cool-project": {

        ... rest of project config omitted

        "architect": {

            "serve": {

                "options": {

                    "port": 1337

                }

            }

        }

    }

}

All options available:

https://github.com/angular/angular-cli/wiki/angular-workspace

Alternatively, you may specify the port each time when running ng serve like this:

ng serve --port 1337

Legacy:

Update for @angular/cli final:

Inside angular-cli.json you can specify the port in the defaults:

"defaults": {

  "serve": {

    "port": 1337

  }

}

Legacy-er:

Tested in angular-cli@1.0.0-beta.22-1

The server in angular-cli comes from the ember-cli project.
To configure the server, create an .ember-cli file in the project root. Add your JSON config in there:

{

   "port": 1337

}

Restart the server and it will serve on that port.

There are more options specified here:
http://ember-cli.com/#runtime-configuration

{

  "skipGit" : true,

  "port" : 999,

  "host" : "0.1.0.1",

  "liveReload" : true,

  "environment" : "mock-development",

  "checkForUpdates" : false

}

In Angular 2 cli@2.3.1,

To run a new project on the different port, one way is to specify the port while you run ng serve command.

ng serve --port 4201

or the other way, you can edit your package.json file scripts part and attached the port to your start variable like I mentioned below and then simply run "npm start"

 "scripts": {



    "ng": "ng",

    "start": "ng serve --port 4201",

    ... : ...,

    ... : ....

}

this way is much better where you don't need to define port explicitly every time.

Use npm scripts instead... Edit your package.json and add the command to script section.

Then just execute npm start

You can now specify the port in the .angular-cli.json under the defaults:

"defaults": {

  "styleExt": "scss",

  "serve": {

    "port": 8080

  },

  "component": {}

}

Tested in angular-cli v1.0.6

For @angular/cli v6.2.1

The project configuration file angular.json is able to handle multiple projects (workspaces) which can be individually served.

ng config projects.my-test-project.targets.serve.options.port 4201

Where the my-test-project part is the project name what you set with the ng new command just like here:

$ ng new my-test-project

$ cd my-test-project

$ ng config projects.my-test-project.targets.serve.options.port 4201

$ ng serve

** Angular Live Development Server is listening on localhost:4201, open your browser on http://localhost:4201/ **

Legacy:

I usually use the ng set command to change the Angular CLI settings for project level.

ng set defaults.serve.port=4201

It changes change your .angular.cli.json and adds the port settings as it mentioned earlier.

After this change you can use simply ng serve and it going to use the prefered port without the need of specifying it every time.

As far as Angular CLI: 7.1.4, there are two common ways to achieve changing the default port.

No. 1

In the angular.json, add the --port option to serve part and use ng serve to start the server.

"serve": {

  "builder": "@angular-devkit/build-angular:dev-server",

  "options": {

    "browserTarget": "demos:build",

    "port": 1337

  },

  "configurations": {

    "production": {

      "browserTarget": "demos:build:production"

    }

  }

},

No. 2

In the package.json, add the --port option to ng serve and use npm start to start the server.

  "scripts": {

    "ng": "ng",

    "start": "ng serve --port 8000",

    "build": "ng build",

    "test": "ng test",

    "lint": "ng lint",

    "e2e": "ng e2e"

  },
