Angular 17 Encrypting and Decrypting Data with Crypto-js

First, let's install crypto-js in our Angular project using NPM:

npm install crypto-js

npm i --save-dev @types/crypto-js


Once CryptoJs is installed, we can import it into our Local Service (EncrDecrService):

import * as CryptoJS from 'crypto-js';


Now we will add two encrypt and decrypt methods to handle encryption and decryption in our service class:

import { Injectable } from '@angular/core';

import * as CryptoJS from 'crypto-js';

@Injectable({

  providedIn: 'root'

})

export class EncrDecrService {

  //Private Key

  key = "encrypt!135790";

  //constructor

  constructor() { } 

  //To encrypt input data

  public encrypt(password: string): string {

    return CryptoJS.AES.encrypt(password, this.key).toString();

  }

  //To decrypt input data

  public decrypt(passwordToDecrypt: string) {

    return CryptoJS.AES.decrypt(passwordToDecrypt, this.key).toString(CryptoJS.enc.Utf8);

  }

}

Using this service in the component class,

import { Component, inject } from '@angular/core';

import { UserinfoComponent } from '../userinfo/userinfo.component';

import { EncrDecrService } from '../encr-decr-service.service';

@Component({

  selector: 'app-user-list',

  standalone: true,

  imports: [UserinfoComponent],

  templateUrl: './user-list.component.html',

  styleUrl: './user-list.component.css'

})

export class UserListComponent {

   user= 'This is user list'

   encrypt ='';

   decripted='';

   private _text = 'system!1233';

   //Constructor

   constructor(private encrDecrService: EncrDecrService) {}

   ngOnInit(): void {

    console.log('Password :' + this._text);

    this.encrypt = this.encrDecrService.encrypt(this._text);   

    console.log('Decrypted password data :', this.encrypt);

    this.decripted = this.encrDecrService.decrypt(this.encrypt);

    console.log('Encripted to Decrypted password data :', this.decripted);

  }

}

nullinjectorerror no provider for httpclient angular 17

In Angular 17 where the standalone true option is set by default, the app.config.ts file is generated in src/app/ and provideHttpClient(). We can be added to the list of providers in app.config.ts Step 1:   To provide HttpClient in a standalone app we could do this in the app.config.ts file, app.config.ts: import { ApplicationConfig } from '@angular/core'; import { provideRouter } from '@angular/router'; import { routes } from './app.routes'; import { provideClientHydration } from '@angular/platform-browser'; //This (provideHttpClient) will help us to resolve the issue  import {provideHttpClient} from '@angular/common/http'; export const appConfig: ApplicationConfig = {   providers: [ provideRouter(routes),  provideClientHydration(), provideHttpClient ()      ] }; The appConfig const is used in the main.ts file, see the code, main.ts : import { bootstrapApplication } from '@angular/platform-browser'; import { appConfig } from ...

React Lifecycle Components | Mounting, Updating, Unmounting

In React, each component has a life-cycle which manipulate during its three main phases. The following three phases are: 1.       Mounting 2.       Updating 3.       Unmounting React does so by “ Mounting ” (adding nodes to the DOM), “ Unmounting ” (removing them from the DOM), and “ Updating ” (making changes to nodes already in the DOM). Mounting - Lifecycle Phase 1 Mounting is used for adding nodes (elements) to the DOM. The React has four built-in methods that gets called, in this order, when mounting a component - 1.       constructor() 2.       getDerivedStateFromProps() 3.       render() 4.       componentDidMount() Note – 1)       The render() method is required and It always be called and the others methods are optional (you will call...
