#5 ✏️Add Editor

Add Forms module

We will add the FormsModule in 📝src/app/app.module.ts as shown below.
import { FormsModule } from '@angular/forms';
@NgModule({
...
imports: [
...
FormsModule,
],
})

Creating the data model

Create new a folder src/app/models. Create a new file 📝src/app/models/post.ts and paste the following code
export class Post {
postId: string;
title: string;
content: string;
createdDate: any;
constructor() {
this.content = '';
}
}

Create the blog service

We will create a service to handle our database operations. Create a new service by making a right-click on the folder 📁servicesand navigating to 'Angular Generator','Component' and provide the name ‘blog’.
Open the 📝src/app/services/blog.service.ts file and add the following import definitions.
import { AngularFirestore } from '@angular/fire/firestore';
import { Post } from '../models/post';
import { map } from 'rxjs/operators';
import { Observable } from 'rxjs';
Inject the AngularFirestore in the constructor.
constructor(private db: AngularFirestore) { }
Now we will add the method to create a new post. The method to add a new blog post is shown at https://github.com/AnkitSharma-007/blogsite/blob/master/src/app/services/blog.service.ts#L14-L17. Put this method in blog.service.ts file.
createPost(post: Post) {
const postData = JSON.parse(JSON.stringify(post));
return this.db.collection('blogs').add(postData);
}

Install CkEditor package

We will use CKEditor for adding and editing our blog post. CKEditor is a Smart WYSIWYG(What you see is what you get) editor which provides us with great editing capabilities.
⏰We already installed into stackblitz @ckeditor/ckeditor5-angular @ckeditor/ckeditor5-build-classic
Imports the CKEditorModule in 📝src/app/app.module.ts as shown below.
import { CKEditorModule } from '@ckeditor/ckeditor5-angular';
@NgModule( {
imports: [
...
CKEditorModule,
],
})

Add the blog editor

We will create a new component for adding and editing the blog. Let’s make a right-click on the folder 📁components. Navigate to 'Angular Generator', select 'Component' and provide the name ‘blog-editor’.

Add a route to the addpost page

Add the route for this component in 📝app.module.ts as shown below:
RouterModule.forRoot([
...
{ path: 'addpost', component: BlogEditorComponent },
...
])

Add CKEditor to BlogEditorComponent

Open 📝src/app/components/blog-editor/blog-editor.component.ts and add the import definitions:
import * as ClassicEditor from '@ckeditor/ckeditor5-build-classic';
import { Post } from 'src/app/models/post';
import { DatePipe } from '@angular/common';
import { BlogService } from 'src/app/services/blog.service';
import { Router, ActivatedRoute } from '@angular/router';
public Editor = ClassicEditor;
ckeConfig: any;
postData = new Post();
formTitle = 'Add';
postId = '';
We will create a method to define the configuration for the blog editor. You can get the method definition from https://github.com/AnkitSharma-007/blogsite/blob/master/src/app/components/blog-editor/blog-editor.component.ts#L50-L66
setEditorConfig() {
this.ckeConfig = {
removePlugins: ['ImageUpload', 'MediaEmbed'],
heading: {
options: [
{ model: 'paragraph', title: 'Paragraph', class: 'ck-heading_paragraph' },
{ model: 'heading1', view: 'h1', title: 'Heading 1', class: 'ck-heading_heading1' },
{ model: 'heading2', view: 'h2', title: 'Heading 2', class: 'ck-heading_heading2' },
{ model: 'heading3', view: 'h3', title: 'Heading 3', class: 'ck-heading_heading3' },
{ model: 'heading4', view: 'h4', title: 'Heading 4', class: 'ck-heading_heading4' },
{ model: 'heading5', view: 'h5', title: 'Heading 5', class: 'ck-heading_heading5' },
{ model: 'heading6', view: 'h6', title: 'Heading 6', class: 'ck-heading_heading6' },
{ model: 'Formatted', view: 'pre', title: 'Formatted' },
]
}
};
}
We will invoke this method inside ngOnInit as shown below.
ngOnInit() {
this.setEditorConfig();
}

Update the BlogEditorComponent template

Open src/app/components/blog-editor/blog-editor.component.html and put the code as shown at https://github.com/AnkitSharma-007/blogsite/blob/master/src/app/components/blog-editor/blog-editor.component.html
<h1>{{formTitle}} Post</h1>
<hr />
<form #myForm="ngForm" (ngSubmit)="myForm.form.valid && saveBlogPost()" accept-charset="UTF-8" novalidate>
<input type="text" class="blogHeader" placeholder="Add title..." class="form-control" name="postTitle"
[(ngModel)]="postData.title" #postTitle="ngModel" required />
<span class="text-danger" *ngIf="myForm.submitted && postTitle.errors?.required">
Title is required
</span>
<br />
<div class="form-group">
<ckeditor name="myckeditor" [config]="ckeConfig" [(ngModel)]="postData.content" #myckeditor="ngModel"
debounce="300" [editor]="Editor"></ckeditor>
</div>
<div class="form-group">
<button type="submit" mat-raised-button color="primary">Save</button>
<button type=" button" mat-raised-button color="warn" (click)="cancel()">CANCEL</button>
</div>
</form>

Add a new blog

We will now implement the feature of adding a new blog to our application. Open 📝src/app/components/blog-editor.component.ts and inject the following service definitions in the constructor.
constructor(private _route: ActivatedRoute,
private datePipe: DatePipe,
private blogService: BlogService,
private _router: Router) { }
Add the following code in @Component decorator DatePipe can be injected.
@Component({
...
providers: [DatePipe]
}
We will create a new method called saveBlogPost which is used to add a new post to our database. The definition for this method is shown below.
saveBlogPost() {
this.postData.createdDate = this.datePipe.transform(Date.now(), 'MM-dd-yyyy HH:mm');
this.blogService.createPost(this.postData).then(
() => {
this._router.navigate(['/']);
}
);
}
This method will be invoked on click of Save button. We will add the following code definition for Cancel button.
cancel() {
this._router.navigate(['/']);
}

Add buttons in Nav bar

We will add the navigation button to blog editor and home page in the nav bar. Add the following code inside the <mat-toolbar> in the file 📝src/app/components/nav-bar/nav-bar.component.html:
<mat-toolbar class="nav-bar mat-elevation-z2">
<button mat-button [routerLink]='[""]'> My blog </button>
<button mat-button [routerLinkActive]='["link-active"]' [routerLink]='["/addpost"]'>
Add Post
</button>
</mat-toolbar>

Add BlogEditorComponent styles

We will add styling for blog editor in 📝styles.scss file with the following code:
.ck-editor__editable {
max-height: 350px;
min-height: 350px;
}
pre {
display: block;
padding: 9.5px;
margin: 0 0 10px;
font-size: 13px;
line-height: 1.42857143;
color: #333;
word-break: break-all;
word-wrap: break-word;
background-color: #f5f5f5;
border: 1px solid #ccc;
border-radius: 4px;
}
blockquote {
display: block;
padding: 10px 20px;
margin: 0 0 20px;
font-size: 17.5px;
border-left: 5px solid #eee;
}
img{
max-width: 100%;
}
