![]() Mar 21, 2018 - Where AngularJS 1.x was limited to a framework, Angular has. Assuming you haven't created a directory yet, let's use ng new to create a new project. With id 41455596 Chrome 57.0.2987 (Mac OS X 10.12.0): Executed 3. Jump start your Angular project with Angular CLI, the complete re-write of the popular AngularJS framework was released in September of 2016. In March 2017 Angular 2 will be renamed to Angular, so I’ll be using the new name in this article. Initially the entry barrier into the world of Angular development was pretty high because of the need to learn and manually configure multiple tools. Even to get started with a simple application, you’d need to learn the TypeScript language (an easy job for Java developers), learn how to configure and use the TypeScript compiler, ES6 modules, a module loader (e.g. SystemJS), test runners, npm, a dev web server. To work on a real-world project, you’d also need to learn how to test and bundle your app for deployment. To jumpstart the development process, the Angular team created a tool called Angular CLI (see ), which is a command-line interface that covers all the stages of creating an Angular application from scaffolding and generating an initial app to deployment. The generated code also includes pre-configured files for unit tests and bundling with the powerful Webpack bundler. While Angular CLI is still in beta, most of the developers like the ease of getting started with new projects. In this article I’ll show you how to create, bundle, and deploy an simple project with Angular CLI. To get started you have to have NodeJS installed on your computer (see ). Both Angular and Angular CLI have lots of dependencies on other packages, which are available at the NPM repository at (it’s similar to Maven Central). NodeJS comes with npm – a package manager that can install individual packages from npmjs.org or use the config file package.json (like pom.xml) to install all project dependencies. I’ll show you how to create the initial project (including package.json) using Angular CLI. After installing NodeJS, you can start using npm in the command prompt window (or the Terminal on Mac) to install all required dependencies. Here’s the command to install Angular CLI globally on your computer (-g is for global): npm install @angular/cli -g After Angular CLI is installed, you can start using its ng command to generate various artifacts such as the new project, components, services as well as building and running the app with included Web server (webpack-dev-server). To create a new project called myproject just enter the following command: ng new myproject This command will create a new directory with the boilerplate project and install all required dependencies – thousands of files in the node_module directory of your project. This sounds like a lot of files to install, but enterprise Java developers are accustomed to this. Depending on the speed of your Internet connection, it can take anywhere from one to five minutes. Download a copy of disk utility for a mac. This time can be substantially decreased by using the Yarn package manager (an alternative to npm), and I described how to do it in. Change directory to your newly generated project, and you’ll see something like this: Figure 1.
