Inserting Code Blocks
This feature allows users to insert code blocks into the editor. The code sample demonstrates how to configure CKEditor 5 to include the CodeBlock plugin and add a button to the toolbar for inserting code blocks.
ClassicEditor.create(document.querySelector('#editor'), { plugins: [CodeBlock], toolbar: ['codeBlock'] })Syntax Highlighting
This feature provides syntax highlighting for different programming languages. The code sample shows how to configure the CodeBlock plugin to support JavaScript and Python syntax highlighting.
ClassicEditor.create(document.querySelector('#editor'), { plugins: [CodeBlock], codeBlock: { languages: [ { language: 'javascript', label: 'JavaScript' }, { language: 'python', label: 'Python' } ] } })Customizing Code Block Styles

ClassicEditor.create(document.querySelector('#editor'), { plugins: [CodeBlock], codeBlock: { styles: [ { element: 'pre', classes: ['custom-code-block'] } ] } })Prism is a lightweight, extensible syntax highlighter. It is a standalone library that can be integrated into various editors and applications. Unlike @ckeditor/ckeditor5-code-block, which is specifically designed for CKEditor 5, Prism can be used with any text editor or web application.
Highlight.js is a popular syntax highlighter that works in the browser as well as on the server. It automatically detects the language of the code block and applies appropriate syntax highlighting. While @ckeditor/ckeditor5-code-block is tailored for CKEditor 5, Highlight.js can be used independently or integrated into different editors.
Ace is a standalone code editor written in JavaScript. It provides syntax highlighting, code folding, and other features for editing code. Unlike @ckeditor/ckeditor5-code-block, which is a plugin for CKEditor 5, Ace is a full-fledged code editor that can be embedded in web applications.
This package implements the code block feature for CKEditor 5.
