Angular WYSIWYG.JS Component

An angular wysiwyg editor component using wysiwyg.js. It also uses prismjs for code highligting.

Prerequisites - dependencies

1. jquery (optionally required by wysiwygjs library)
2. fontawesome (required by wysiwygjs libary)
3. prismjs (code highlighter used by this component)

Installation

npm install --save ng-wysiwygjs

Setup

1. Add dependent libaries to .angular-cli.json file

       "styles": [
           "styles.css",
           "../node_modules/font-awesome/css/font-awesome.css",
           "../node_modules/prismjs/themes/prism-okaidia.css"
       ],
       "scripts": [
           "../node_modules/jquery/dist/jquery.min.js",
           "../node_modules/wysiwyg.js/src/wysiwyg.js",
           "../node_modules/wysiwyg.js/src/wysiwyg-editor.js",
           "../node_modules/prismjs/prism.js",
           "../node_modules/prismjs/components/prism-typescript.js",
           ...
       ],
   

2. (Optional) add programming languages of choice to be used for code highlighting. Full list is:

    "scripts": [
           "../node_modules/prismjs/components/prism-typescript.js",
           "../node_modules/prismjs/components/prism-go.js",
           "../node_modules/prismjs/components/prism-markup.min.js",
           "../node_modules/prismjs/components/prism-css.min.js",
           "../node_modules/prismjs/components/prism-scss.min.js",
           "../node_modules/prismjs/components/prism-sass.min.js",
           "../node_modules/prismjs/components/prism-less.min.js",
           "../node_modules/prismjs/components/prism-typescript.min.js",
           "../node_modules/prismjs/components/prism-php.min.js",
           "../node_modules/prismjs/components/prism-go.min.js",

           "../node_modules/prismjs/components/prism-rust.min.js",
           "../node_modules/prismjs/components/prism-c.min.js",
           "../node_modules/prismjs/components/prism-java.min.js",        
           "../node_modules/prismjs/components/prism-lua.min.js",
           "../node_modules/prismjs/components/prism-dart.min.js",
           "../node_modules/prismjs/components/prism-swift.min.js",
           "../node_modules/prismjs/components/prism-scala.min.js",
           "../node_modules/prismjs/components/prism-sql.min.js",
           "../node_modules/prismjs/components/prism-json.min.js",
           "../node_modules/prismjs/components/prism-r.min.js",
           "../node_modules/prismjs/components/prism-sas.min.js",
           "../node_modules/prismjs/components/prism-matlab.min.js",
           "../node_modules/prismjs/components/prism-bash.min.js",

           "../node_modules/prismjs/components/prism-vim.min.js"
    ]

Note: This is just the most common programming languages supported by Prismjs personally selected by author.

Usage

1. Import component module

       import { WygEditorModule } from 'wyg-editor/wyg-editor.module';
       ...
   
       @NgModule({
       ...
       imports: [
           ...
           WygEditorModule
       ],
       providers: [],
       bootstrap: [AppComponent]
       })
       export class AppModule { }

2. Use wyg-editor in your component class

   • Component

         import { WygEditorComponent } from 'wyg-editor/wyg-editor.component';
     
         @Component({
         selector: 'app-demo',
         templateUrl: './demo.component.html',
         styleUrls: ['./demo.component.css']
         })
         export class DemoComponent implements OnInit {
     
         public testContent: string;
     
         constructor() { }
     
         ngOnInit() {
             this.testContent = "<p>Hello world!</p>";
         }
     
         }

   • Template

         <wygeditor [(ngModel)]="testContent" name="testContent"></wygeditor>

   • Full example

         <h1>ng-wysiwygjs & prismjs demo</h1>
     
         <div>
             <wygeditor [(ngModel)]="testContent" name="testContent"></wygeditor>
         </div>
     
         <!--<div>{{testContent}}</div>-->
         <h2>Note:</h2>
         <p>Press <strong>Ctl+Shift+h</strong> to highlight all code blocks</p>
         <h2>Output: </h2>
         <div [innerHTML]="testContent" ></div>

3. Using code highlighting

   • Click on </> icon of the toolbar to select programming language
   • Edit your code in pre-format code block
   • Press Ctrl+Shift+h to highlight your code blocks

Customisation

• Changing format: you can change format of the editor by adding your .css file to .angular-cli.json

TODOs

• Testing
• Get focus back to editor after code highligting (this is a current issue of angular 4 with new renderer2)
