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


    The CLI is now in 1.0. If you are updating from a beta or RC version, check out our 1.0 Update Guide.

    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.


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

    BEFORE YOU INSTALL: please read the prerequisites

    npm install -g @angular/cli


    ng help

    Generating and serving an Angular project via a development server

    ng new 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 --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
    # if in the directory src/app you can also run
    ng g component feature/new-cmp
    # and 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.

    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

    If you are updating to 1.0 from a beta or RC version, check out our 1.0 Update Guide.

    Development Hints for working on Angular CLI

    Working with master

    git clone
    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. Additionally, this repository publishes several packages and we use special logic to load all of them on development setups.

    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.

    To run the Angular CLI test suite use the node tests/run_e2e.js command. It can also receive a filename to only run that test (e.g. node tests/run_e2e.js tests/e2e/tests/build/dev-build.ts).

    As part of the test procedure, all packages will be built and linked. You will need to re-run npm link to re-link the development Angular CLI environment after tests finish.


    The documentation for the Angular CLI is located in this repo's wiki.
