As of right now that feature is not supported, however if this is something that bothers you an alternative would be in your package.json...

"scripts": {

  "start": "ng serve --host foo.bar --port 80"

}

This way you can simply run npm start

Another option if you want to do this across multiple projects is to create an alias, which you can potentially name ngserve which will execute your above command.

You can configure the default HTTP port and the one used by the LiveReload server with two command-line options :

ng serve --host 0.0.0.0 --port 4201 --live-reload-port 49153

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

This changed in the latest Angular CLI.

The file name changed to angular.json, and the structure also changed.

This is what you should do:

"projects": {

    "project-name": {

        ...

        "architect": {

            "serve": {

                "options": {

                  "host": "foo.bar",

                  "port": 80

                }

            }

        }

        ...

    }

}

Another option is to run ng serve command with the --port option e.g

ng serve --port 5050 (i.e for port 5050)

Alternatively, the command: ng serve --port 0, will auto assign an available port for use.

You can save these in a file, but you have to to put it in .ember-cli (at the moment, at least); see https://github.com/angular/angular-cli/issues/1156#issuecomment-227412924

{

"port": 4201,

"liveReload": true,

"host": "dev.domain.org",

"live-reload-port": 49153

}

edit: you can now set these in angular-cli.json as of commit https://github.com/angular/angular-cli/commit/da255b0808dcbe2f9da62086baec98dacc4b7ec9, which is in build 1.0.0-beta.30

We have two ways to change default port number in Angular.

First way to cli command:

ng serve --port 2400 --open

Second way is by configuration at the location: ProjectNamenode_modules@angular-devkitbuild-angularsrcdev-serverschema.json.

Make changes in schema.json file.

{
"title": "Dev Server Target",
"description": "Dev Server target options for Build Facade.",
"type": "object",
"properties": {
"browserTarget": {
"type": "string",
"description": "Target to serve."
},
"port": {
"type": "number",
"description": "Port to listen on.",
"default": 2400
},

If your are on windows you can do it this way :

1. In your project root directory, Create file run.bat


2. Add your command with your choice of configurations in this file. For Example

ng serve --host 192.168.1.2 --open

3. Now you can click and open this file whenever you want to serve.

This not standard way but comfortable to use (which I feel).

here is what i put into package.json (running angular 6):

{

  "name": "local-weather-app",

  "version": "1.0.0",

  "scripts": {

    "ng": "ng",

    "start": "ng serve --port 5000",

    "build": "ng build",

    "test": "ng test",

    "lint": "ng lint",

    "e2e": "ng e2e"

  },

Then a plain npm start will pull in the contents of start. Could also add other options to contents

enter image description here

Only one thing you have to do. Type this in in your Command Prompt:
ng serve --port 4021 [or any other port you want to assign eg: 5050, 5051 etc ]. No need to do changes in files.
