Markdown to HTML Conversion
This feature allows you to initialize CKEditor with the Markdown plugin, enabling the conversion of markdown content to HTML within the editor.
const ClassicEditor = require('@ckeditor/ckeditor5-build-classic');
const Markdown = require('@ckeditor/ckeditor5-markdown-gfm/src/markdown');
ClassicEditor
.create(document.querySelector('#editor'), {
plugins: [Markdown],
toolbar: ['bold', 'italic', 'link']
})
.then(editor => {
console.log('Editor was initialized', editor);
})
.catch(error => {
console.error(error.stack);
});
HTML to Markdown Conversion
This feature allows you to convert the HTML content within the CKEditor back to markdown format, making it easy to store or manipulate markdown data.
const ClassicEditor = require('@ckeditor/ckeditor5-build-classic');
const Markdown = require('@ckeditor/ckeditor5-markdown-gfm/src/markdown');
ClassicEditor
.create(document.querySelector('#editor'), {
plugins: [Markdown],

})
.then(editor => {
const markdownData = editor.plugins.get('Markdown').getMarkdown();
