Angular 2 CLI

Angular 2 CLI is a command-line interface tool that simplifies the development and deployment of Angular applications. It provides a set of helpful commands for creating, building, testing, and deploying Angular projects. This tool is built on top of the Angular framework and is designed to enhance developer productivity.

Features

• Application Generation: With a single command, you can generate a new Angular application skeleton. The CLI sets up the necessary project structure and configuration files, making it easier to get started.

  ng new my-app
  

• Development Server: The CLI comes with a built-in development server that allows you to run your application locally during development. It automatically refreshes the browser whenever you make code changes, making the development process faster and more efficient.

  ng serve
  

• Code Generation: The CLI provides a set of generators for generating different components of an Angular application, such as components, services, directives, and modules. This helps in creating boilerplate code with ease, saving a significant amount of development time.

  ng generate component my-component
  

• Testing: Angular 2 CLI integrates with popular testing frameworks like Jasmine and Karma, allowing you to easily run unit tests for your application. It also provides tools for generating test stubs and running end-to-end tests.

  ng test
  

• Build Optimization: The CLI optimizes the build process by automatically bundling and minifying the application code. It also generates hashed file names to facilitate cache-busting and improve performance.

  ng build --prod
  

• Deployment: The CLI simplifies the deployment process by providing a command to build an optimized version of the application for production. This makes it easy to deploy the application to a web server or host it on a cloud platform.

  ng build --prod
  

Conclusion

Angular 2 CLI is a powerful tool that enhances the Angular development experience. It provides a streamlined workflow for creating, building, and deploying Angular applications. Whether you are a beginner or an experienced developer, the CLI can significantly boost your productivity and help you create high-quality Angular applications more efficiently.
