Angular 2 Angular-cli


Here you will find how to start with angular-cli , generating new component/service/pipe/module with angular-cli , add 3 party like bootstrap , build angular project.

Create empty Angular2 application with angular-cli


Run the following commands with cmd from new directory folder:

  1. npm install -g @angular/cli or yarn global add @angular/cli
  2. ng new PROJECT_NAME
  4. ng serve

Open your browser at localhost:4200

Generating Components, Directives, Pipes and Services

just use your cmd: You can use the ng generate (or just ng g) command to generate Angular components:

  • 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-classt
  • Interface: ng g interface my-new-interface
  • Enum: ng g enum my-new-enum
  • Module: ng g module my-module

Adding 3rd party libs

In angular-cli.json you can change the app configuration.

If you want to add ng2-bootstrap for example:

  1. npm install ng2-bootstrap --save or yarn add ng2-bootstrap

  2. In angular-cli.json just add the path of the bootstrap at node-modules.

build with angular-cli

In angular-cli.json at outDir key you can define your build directory;

these are equivalent

ng build --target=production --environment=prod
ng build --prod --env=prod
ng build --prod

and so are these

ng build --target=development --environment=dev
ng build --dev --e=dev
ng build --dev
ng build

When building you can modify base tag () in your index.html with --base-href your-url option.

Sets base tag href to /myUrl/ in your index.html

ng build --base-href /myUrl/
ng build --bh /myUrl/

New project with scss/sass as stylesheet

The default style files generated and compiled by @angular/cli are css.

If you want to use scss instead, generate your project with:

ng new project_name --style=scss

If you want to use sass, generate your project with:

ng new project_name --style=sass

Set yarn as default package manager for @angular/cli

Yarn is an alternative for npm, the default package manager on @angular/cli. If you want to use yarn as package manager for @angular/cli follow this steps:


To set yarn as @angular/cli package manager:

ng set --global packageManager=yarn

To set back npm as @angular/cli package manager:

ng set --global packageManager=npm
