Angular CLI

CLI for Angular applications based on the ember-cli project.

Note

The CLI is now in Release Candidate (RC). If you are updating from a beta version, check out our [RC Update Guide] (https://github.com/angular/angular-cli/wiki/stories-rc-update).

If you wish to collaborate, check out our issue list.

Before submitting new issues, have a look at issues marked with the type: faq label.

Prerequisites

Both the CLI and generated project have dependencies that require Node 6.9.0 or higher, together with NPM 3 or higher.

Installation

BEFORE YOU INSTALL: please read the prerequisites

npm install -g @angular/cli

Usage

ng help

Generating and serving an Angular project via a development server

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
# but if you were to run
ng g component ../newer-cmp
# your component will be generated in src/app/newer-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`

Updating Angular CLI

If you're using Angular CLI beta.28 or less, you need to uninstall angular-cli package. It should be done due to changing of package's name and scope from angular-cli to @angular/cli:

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli

To update Angular CLI to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
npm install --save-dev @angular/cli@latest
npm install

You can find more details about changes between versions in CHANGELOG.md.

Development Hints for hacking on Angular CLI

Working with master

git clone https://github.com/angular/angular-cli.git
cd angular-cli
npm link

npm link is very similar to npm install -g except that instead of downloading the package from the repo, the just cloned angular-cli/ folder becomes the global package. Any changes to the files in the angular-cli/ folder will immediately affect the global @angular/cli package, allowing you to quickly test any changes you make to the cli project.

Now you can use @angular/cli via the command line:

ng new foo
cd foo
npm link @angular/cli
ng serve

npm link @angular/cli is needed because by default the globally installed @angular/cli just loads the local @angular/cli from the project which was fetched remotely from npm. npm link @angular/cli symlinks the global @angular/cli package to the local @angular/cli package. Now the angular-cli you cloned before is in three places: The folder you cloned it into, npm's folder where it stores global packages and the Angular CLI project you just created.

You can also use ng new foo --link-cli to automatically link the @angular/cli package.

Please read the official npm-link documentation and the npm-link cheatsheet for more information.
