Quill — Modern WYSIWYG Rich Text Editor for the Web

Introduction

Quill is a modern WYSIWYG editor designed for compatibility and extensibility. It uses a document model called Parchment that closely mirrors the DOM, making it predictable and easy to extend with custom content types, formats, and embeds.

What Quill Does

• Renders rich text content with consistent cross-browser output
• Provides a modular toolbar with built-in formatting controls
• Expresses content changes as operational transforms (Deltas) for reliable collaboration
• Supports custom blots to embed any content type (video, formulas, mentions)
• Offers two bundled themes: Snow (toolbar) and Bubble (tooltip-based)

Architecture Overview

Quill is built around three layers: Parchment (the document model that maps formats to DOM nodes), Delta (a JSON-based representation of document content and changes), and Modules (pluggable components for toolbar, keyboard bindings, clipboard, and history). The Delta format makes it straightforward to implement real-time collaboration or persistent storage without parsing HTML.

Self-Hosting & Configuration

• Install via npm, yarn, or include from a CDN
• Initialize with a container element and an options object specifying theme and modules
• Customize the toolbar by passing an array of format groups
• Extend functionality by writing custom modules that hook into editor events
• Use the quill.getContents() method to retrieve Delta JSON for storage

Key Features

• Delta format provides a structured JSON representation of rich text content
• Custom Blots let developers define new inline, block, or embed formats
• Clipboard module handles paste normalization across browsers
• Full keyboard binding customization for shortcuts and hotkeys
• Active community with a wide ecosystem of plugins and integrations

Comparison with Similar Tools

• TinyMCE — more features out of the box with a plugin marketplace; Quill is lighter and more developer-friendly
• ProseMirror — schema-based and highly customizable; Quill is simpler to get started with
• CKEditor — enterprise-grade with collaboration built in; Quill is fully open source and MIT-licensed
• Slate — React-first framework for building custom editors; Quill works as a standalone drop-in component
• Tiptap — built on ProseMirror with a modern API; Quill has broader legacy adoption

FAQ

Q: What is a Delta? A: A Delta is a JSON object describing document content or changes as a series of insert, delete, and retain operations.

Q: Can Quill handle real-time collaboration? A: Yes. The Delta format is designed for operational transformation, making it compatible with collaboration backends like ShareDB or Yjs.

Q: Is Quill framework-agnostic? A: Yes. Quill is a vanilla JavaScript library and works with React, Vue, Angular, or plain HTML.

Q: How do I customize the toolbar? A: Pass a toolbar configuration array in the modules option when initializing the editor.
