How to change the server port from 3000?

1-> Using File Default Config- Angular-cli comes from the ember-cli project. To run the application on specific port, create an .ember-cli file in the project root. Add your JSON config in there:

{ "port": 1337 }

2->Using Command Line Tool Run this command in Angular-Cli

ng serve --port 1234

To change the port number permanently:

Goto

node_modules/angular-cli/commands/server.js

Search for var defaultPort = process.env.PORT || 4200; (change 4200 to anything else you want).

You can change it inside bs-config.json file as mentioned in the docs https://github.com/johnpapa/lite-server#custom-configuration

For example,

{
  "port": 8000,
  "files": ["./src/**/*.{html,htm,css,js}"],
  "server": { "baseDir": "./src" }
}

Using Angular 4 and the cli that came with it I was able to start the server with $npm start -- --port 8000. That worked ok: ** NG Live Development Server is listening on localhost:8000, open your browser on http://localhost:8000 **
