angular-cli server - how to specify default port

Question

Using angular-cli with the ng serve command, how can I specify a default port so I do not need to manually pass the --port flag every time?

I'd like to change from the default port 4200.

Update for @angular/cli@9.x: and over

In angular.json you can specify a port per "project"

"projects": {
    "my-cool-project": {
        ... rest of project config omitted
        "architect": {
            "serve": {
                "options": {
                    "port": 1337
                }
            }
        }
    }
}

All options available:

https://angular.io/guide/workspace-config#project-tool-configuration-options

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

ng serve --port 1337

With this approach you may wish to put this into a script in your package.json to make it easier to run each time / share the config with others on your team:

"scripts": {
    "start": "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
}
