const ClassicEditor = require('@ckeditor/ckeditor5-editor-classic/src/classiceditor');
const Editor = require('@ckeditor/ckeditor5-core/src/editor/editor');
ClassicEditor.create(document.querySelector('#editor'))
.then(editor => {
console.log('Editor was initialized', editor);
})
.catch(error => {
console.error(error.stack);
});Plugin Management
This feature allows you to create and manage plugins for CKEditor 5. The code sample demonstrates how to create a custom plugin and include it in the editor configuration.
const Plugin = require('@ckeditor/ckeditor5-core/src/plugin');
class MyPlugin extends Plugin {
init() {
console.log('MyPlugin was initialized');
}
}
ClassicEditor.create(document.querySelector('#editor'), {
plugins: [ MyPlugin ]
})
.then(editor => {
console.log('Editor with MyPlugin was initialized', editor);
})
.catch(error => {
console.error(error.stack);
});Command Management
This feature allows you to create and manage commands in CKEditor 5. The code sample demonstrates how to create a custom command and execute it within the editor.
const Command = require('@ckeditor/ckeditor5-core/src/command');
class MyCommand extends Command {
execute() {
console.log('MyCommand executed');
}
}
ClassicEditor.create(document.querySelector('#editor'))
.then(editor => {
editor.commands.add('myCommand', new MyCommand(editor));
editor.execute('myCommand');
})
.catch(error => {
console.error(error.stack);
