Angular CLI

The Angular CLI

The Angular CLI is a command-line interface tool which allows you to scaffold, develop, test, deploy, and maintain Angular applications directly from a command shell.

Angular CLI is published on npm as the @angular/cli package and includes a binary named ng. Commands invoking ng are using the Angular CLI.

Try Angular without local setup

If you are new to Angular, you might want to start with Try it now!, which introduces the essentials of Angular in the context of a ready-made basic online store app for you to examine and modify. This standalone tutorial takes advantage of the interactive StackBlitz environment for online development. You don't need to set up your local environment until you're ready.

CLI command-language syntax

Angular CLI roughly follows Unix/POSIX conventions for option syntax.

Boolean options

Boolean options have two forms: --this-option sets the flag to true, --no-this-option sets it to false. You can also use --this-option=false or --this-option=true. If neither option is supplied, the flag remains in its default state, as listed in the reference documentation.

Array options

Array options can be provided in two forms: --option value1 value2 or --option value1 --option value2.

Key/value options

Some options like --define expect an array of key=value pairs as their values. Just like array options, key/value options can be provided in two forms: --define 'KEY_1="value1"' KEY_2=true or --define 'KEY_1="value1"' --define KEY_2=true.

Relative paths

Options that specify files can be given as absolute paths, or as paths relative to the current working directory, which is generally either the workspace or project root.
