Angular2 CLI

The Angular CLI is a command-line interface tool that you use to initialize, develop, scaffold, and maintain Angular applications directly from a command shell.

Verify CLI

Before moving to Angular CLI commands, we have to ensure that Angular CLI is installed on your machine. If it is installed, you can verify it by using the command − ng version

If CLI is not installed, then use the below command to install it.

npm install -g @angular/cli

To create, run an application in Angular, use the below syntax 

ng new [PROJECT-NAME]
cd [PROJECT-NAME]
ng serve

Navigate to . http://localhost:4200/ The app will automatically reload if you change any of the source files.

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

ng serve --host 0.0.0.0 --port 4201

Generating Components, Directives, Pipes and Services
You can use the ng generate (or just ng g) command to generate Angular components:

ng generate component my-new-component

ng g component my-new-component //using the alias

//components support relative path generation

//if in the directory src/app/feature/ and you run

ng g component new-cmp

//your component will be generated in src/app/feature/new-cmp 

You can find all possible blueprints in the table below:

scaffold	usage
Component	ng g component my-new-component
Directive	ng g directive my-new-directive
Pipe	ng g pipe my-new-pipe
Service	ng g service my-new-service
Class	ng g class my-new-class
Guard	ng g guard my-new-guard
Interface	ng g interface my-new-interface
Enum	ng g enum my-new-enum
Module	ng g module my-module

angular-cli will add reference to components, directives and pipes automatically in the app.module.ts. If you need to add this references to another custom module, follow this steps:

1. ng g module new-module to create a new module
2. call ng g component new-module/new-component

This should add the new component, directive or pipe reference to the new-module you've created.
