How to Work with a Text Editor in an Angular 8 Application

Introduction

 

In this article, we will learn how to add a text editor in an Angular 8 application. The text editor is a program for adding and editing text. In this demo, we use 'ng2-ckeditor' editor. Learn more about Cheditor.

 

Prerequisites

• Basic Knowledge of Angular 2 or higher
• Visual Studio Code
• Visual Studio and SQL Server Management studio
• Node and NPM installed
• Bootstrap

Step 1

 

Create an Angular project by using the following command.

ng new TextEditor

Step 2

 

Open this project in Visual Studio Code and install bootstrap by using the following command:

npm install bootstrap --save

Now open styles.css file and add Bootstrap file reference. To add a reference in styles.css file, add this line:

@import '~bootstrap/dist/css/bootstrap.min.css';

Step 3

 

Now install ng2-ckeditor library in this project, to install ng2-ckeditor library use the following command:

npm install ng2-ckeditor

Now add CKEditor javascript reference in index.html file,open Index.html file and the following line:

<script src="https://cdn.ckeditor.com/4.9.2/full-all/ckeditor.js"></script>

Step 4 

 

Now include CKEditorModule in app.module.ts file

 

 

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { CKEditorModule } from 'ng2-ckeditor';
import { TextEditorComponent } from './text-editor/text-editor.component';
import { HttpClientModule } from '@angular/common/http';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { PagecontentComponent } from './pagecontent/pagecontent.component';
@NgModule({
  declarations: [
    AppComponent,
    TextEditorComponent,
    PagecontentComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    CKEditorModule,
    HttpClientModule,
    FormsModule,
    ReactiveFormsModule

  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 5

 

Now create a service to call the Web API by using the following command:

ng g s Content

Now add the following line Content.service.ts file:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable({
  providedIn: 'root'
})
export class ContentService {
  url :any;
  constructor(private http: HttpClient) { }
  AddUpdateContent(pagecontent) {
    debugger
    this.url = 'http://localhost:56357/Api/Contents/saveconetnt';
    return this.http.post(this.url, pagecontent);
}
Getcontent() {
  debugger
  this.url = 'http://localhost:56357/Api/Contents/Getpagdata';
  return this.http.get(this.url);
}
GetcontentById(Id) {
  debugger
  this.url = 'http://localhost:56357/Api/Contents/GetpagecontentBy?Id='+Id;
  return this.http.get(this.url);
}
}

Step 6

 

Create a class named "Content" by using the following command and add the following lines:

export class Content {
    Id:number;
    Title:string;
    Content:string;
}

Step 7

 

Now let's create 3 new components by using the following commands:

1. Texteditor
2. Pagecontent
3. detailspost

ng g c Texteditor
ng g c pagecontent
ng g c detailspost

Step 8

 

Now, open texteditor.component.html and add the following HTML code to design the registration form:

<form role="form" #myForm="ngForm" accept-charset="UTF-8" (ngSubmit)="onSubmit()" novalidate style="margin: 30px;">
    <div class="form-group">
        <input autofocus autocomplete="none" type="text" name="UserName" placeholder="Enter Title"
            [(ngModel)]="contentdata.Title" class="form-control" required #PageContentTitle="ngModel"
            id="PageContentTitle">
    </div>
    <ckeditor [(ngModel)]="contentdata.Content" #PageContent="ngModel" name="PageContent" required
        [config]="ckeConfig" debounce="500">
    </ckeditor>
    <div class="form-group mt-4">
        <div class="row">
            <div class="col-3 col-md-3 mb-3">
                <button type="submit" class="btn btn-info">Submit</button>
            </div>
        </div>
    </div>
</form>

Open texteditor.componet.ts file and add the following lines:

import { Component, OnInit, ViewChild ,ElementRef} from '@angular/core';
import { ContentService } from "../content.service";
import { Content } from "../content";
import { FormGroup, FormBuilder, Validators, NgForm } from '@angular/forms';
import { Router } from '@angular/router';

@Component({
  selector: 'app-text-editor',
  templateUrl: './text-editor.component.html',
  styleUrls: ['./text-editor.component.css']
})
export class TextEditorComponent implements OnInit {
  name = 'ng2-ckeditor';
  ckeConfig: any;
   mycontent: string;
  log: string
  @ViewChild('PageContent') PageContent: any;
  res: any;

  constructor(private contentservice:ContentService,private router: Router) { }
  contentdata=new Content();

  ngOnInit() {
    this.Getcontent()
    this.ckeConfig = {
      allowedContent: false,
      extraPlugins: 'divarea',
      forcePasteAsPlainText: true
    };
  }
  onSubmit()
  {
    debugger;
    debugger;
    this.contentservice.AddUpdateContent(this.contentdata).subscribe((data : any) => {
      debugger;
      alert("Data saved Successfully");
      this.router.navigate(['/Post']);

    })
  }
  Getcontent()
  {
    this.contentservice.Getcontent().subscribe((data:any)=>{
      this.res=data;
      console.log(this.res);
    })
  }
}

Step 9

 

Now, open pagecontent.component.html and add the following HTML:

<table class="table">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">Title</th>
      <th scope="col">Content</th>
       <th scope="col">Details</th>
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let data of res">
      <th scope="row">{{data.Id}}</th>
      <td>{{data.Title}}</td>
      <td>{{data.Content}}</td>
      <td>  <button (click)="GetcontentById(data.Id)" type="submit" class="btn btn-info">Details</button></td>
    </tr>
  </tbody>
</table>

Open pagecontent.componet.ts file and add the following lines:

import { Component, OnInit } from '@angular/core';
import { ContentService } from "../content.service";
import { Router } from '@angular/router';
@Component({
  selector: 'app-pagecontent',
  templateUrl: './pagecontent.component.html',
  styleUrls: ['./pagecontent.component.css']
})
export class PagecontentComponent implements OnInit {
  res: any;
  terms: any;
  cont: any;

  constructor(private contentservice:ContentService,private router: Router) { }

  ngOnInit() {
   this.Getcontent()
  }
  Getcontent()
  {
    this.contentservice.Getcontent().subscribe((data:any)=>{
      this.res=data;
      this.terms= this.res[1].pageContentTitle;
      this.cont= this.res[1].Content;
      console.log(this.res);
    })
  }
  GetcontentById(id:number)
  {
    this.router.navigate(['/Details'], { queryParams: { Id: id } });
  }

}

Step 10

 

Now, open detailspost.component.html and add the following HTML:

<div>
        <div>
            <h5 style="color:orange;text-align: center">{{this.Title}}</h5>
            <hr style="color: blue;">
              <span>
              <div style="color:#788594" [innerHTML]="this.content"></div>
              </span>
        </div>
    </div>

Open detailspost.componet.ts file and add the following lines:

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params } from '@angular/router';
import { ContentService } from '../content.service';

@Component({
  selector: 'app-detailspost',
  templateUrl: './detailspost.component.html',
  styleUrls: ['./detailspost.component.css']
})
export class DetailspostComponent implements OnInit {
  res: any;
  Title: any;
  content: any;

  constructor( private route: ActivatedRoute,private contentservice:ContentService) { }

  ngOnInit() {
    let Id = this.route.snapshot.queryParams["Id"]
   this.GetcontentById(Id);
  }
  GetcontentById(Id:string)
  {
     this.contentservice.GetcontentById(Id).subscribe((data: any)=>{
       this.res=data;
       this.Title=this.res.Title
       this.content=this.res.Content
       console.log(this.res);
    });
  }
}

Step 11

 

Now, open app-routing.module.ts file and add the following lines to create routing:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { PagecontentComponent } from './pagecontent/pagecontent.component';
import { TextEditorComponent } from './text-editor/text-editor.component';
import { DetailspostComponent } from './detailspost/detailspost.component';

const routes: Routes = [
  { path: '', component: TextEditorComponent },
  { path: 'Post', component: PagecontentComponent },
  { path: 'Details', component: DetailspostComponent }


]
@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

Step 12 - Create a new Web API project

 

Open Visual Studio and create a new project.

 

 

 

Step 13

 

Change the name to Texteditor.

 

 

Step 14

 

Choose the template as Web API.

 

 

Step 15 

 

Right-click the Models folder from Solution Explorer and go to Add >> New Item >> data.

 

 

 

Step 16

 

Click on the "ADO.NET Entity Data Model" option and click "Add".

 

 

 

Step 17

 

Select EF Designer from the database and click the "Next" button and Add the connection properties. Select the database name on the next page and click OK.

 

 

 

Step 18

 

Check the "Table" checkbox. The internal options will be selected by default. Now, click on the "Finish" button. 

 

Our data model is created now.

 

Step 19

 

Right-click on the Models folder and add a class Response. Now, paste the following code in these classes. 

public class Response
   {
       public string Status { get; set; }
       public string Message { get; set; }
   }

 Right-click on the Controllers folder and add a new controller. Name it as "Content controller" and add the following namespace in the Content controller.

using TextEditor.Models;

Now, add a method to insert and update data into the database.

 

 

Step 20 - Complete Content controller code 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using TextEditor.Models;

namespace TextEditor.Controllers
{
    public class ContentsController : ApiController
    {
        [HttpPost]
        public object saveconetnt(Content Con)
        {
            try
            {
                dbCoreEntities2 db = new dbCoreEntities2();
                Post Em = new Post();
                if (Em.Id == 0)
                {
                    Em.Content = Con.PageContent;
                    Em.Title =Con.PageContentTitle ;
                    db.Posts.Add(Em);
                    db.SaveChanges();
                    return new Response
                    { Status = "Success", Message = "SuccessFully Saved." };
                }
            }
            catch (Exception ex)
            {

                throw;
            }
            return new Response
            { Status = "Error", Message = "Invalid Data." };
        }
       [Route("Api/Contents/Getpagdata")]
        [HttpGet]
        public object Getpagecontent()
        {
            dbCoreEntities2 db = new dbCoreEntities2();
            return db.Posts.ToList();
        }
        //[Route("Api/Login/")]
        [HttpGet]
        public object GetpagecontentById(int id)
        {
            dbCoreEntities2 db = new dbCoreEntities2();
            var obj = db.Posts.Where(x => x.Id == id).ToList().FirstOrDefault();
            return obj;
        }
    }

}

Step 21

 

Now, let's enable CORS. Go to Tools, open NuGet Package Manager, search for CORS, and install the "Microsoft.Asp.Net.WebApi.Cors" package. Open Webapiconfig.cs and add the following lines:

EnableCorsAttribute cors = new EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);

Step 22

 

Now, go to visual studio code and run the project by using the following command: 'npm start' 

 

 

Enter some values, add styles to text in text editor and click on the submit button.

 

 

Click on the details button and check.
