To start working with Angular 2, you need to do the below steps:
1. Npm: This is known as the node package manager that is used to work with the open source repositories. Angular JS has dependencies on other components. And npm can be used to download these dependencies and attach them to your project. The best way to install npm is to install node using the node.js installer. npm is installed as part of node.
2. Go to Node js official website and choose the installer to download, depending on the operating system. For the purpose of this exercise, download the Windows 64 bit version.
3. Once you’ve installed Node.js, you can make sure you’ve got the very most recent version of npm using npm itself:
npm install npm -g
(on Linux, you can add the “sudo”). Running this update will give you the most recent stable version of npm, also supported by npm Inc.
4. In the command prompt, you can enter “npm version” command and you will get the npm version.
5. Install angular-cli using NPM. “npm install -g angular-cli“. Linux users will want to run this command with sudo.
6. Create a new Angular 2 project. ng new PROJECT_NAME. (This will take a few minutes.)

7. After Successfully create a project, If you go into the root directory of the your project and enter the command “ng serve“, angular-cli will compile your project and start serving it. In the output, you’ll see the address your application is getting served at.
