Before you install, check the prerequisite- The Angular CLI and generated project have dependencies that require Node 6.10.3 or higher, together with NPM 3 or higher.

Installation –  
npm install -g @angular/cli

Example – In this example, I will show - “How to install are upgrade Angular CLI”?
Open Node.js Command Prompt – 
Your environment has been set up for using Node.js 6.10.3 (x64) and npm.

Generating Commands - Components, Directives, Pipes, Services and so on
1.     Component  -  ng g component my-login
2.     Directive  - ng g directive my-directive
3.     Class  -  ng g class my-class
4.     Pipe  -    ng g pipe my-pipe
5.     Service    - ng g service my-service
6.     Guard   -   ng g guard my-guard
7.     Interface  -          ng g interface my-interface
8.     Enum -      ng g enum my-enum
9.     Module - ng g module my-module

Example looks like
F:\AngularTestApp\DemoApp\MyApp>ng generate component login
create src/app/login/login.component.html (24 bytes)
create src/app/login/login.component.spec.ts (621 bytes)
create src/app/login/login.component.ts (325 bytes)

React | Encryption and Decryption Data/Text using CryptoJs

To encrypt and decrypt data, simply use encrypt () and decrypt () function from an instance of crypto-js.

AES . encrypt ( JSON . stringify ( data ),  'my-secret-key@123' ). toString (); Step 3 -Decrypt    // Decrypt    var   bytes  =  CryptoJS . AES . decrypt ( ciphertext ,  'my-secret-key@123' );    var   decryptedData  =  JSON . parse ( bytes . toString ( CryptoJS . enc . Utf8 )); As an Example,   import   React   from   'react' ; import   './App.css' ; //Including all libraries, for access to extra methods. var   CryptoJS  =  require ( "crypto-js" ); function   App () {    var   data

"scripts" : [                "../node_modules/crypto-js/crypto-js.js"               ] Steps 3 –  Create a service class “ EncrDecrService ” for  encrypts and decrypts get/set methods . Import “ CryptoJS ” in the service for using  encrypt and decrypt get/set methods . import  {  Injectable  }  from   '@angular/core' ; import   *   as   CryptoJS   from   'crypto-js' ; @ Injectable ({    providedIn:   'root' }) export   class   EncrDecrS
