n8n Chat Widget for Unlimited (German language version)

This is a lightweight, embeddable chat widget that connects to an n8n chat webhook endpoint. It has been customized by ETH Library for integration into internal services such as Unlimited D (Confluence-based). The code is based on https://github.com/WayneSimpson/n8n-chatbot-template and is an alternative to the official n8n widget (https://www.npmjs.com/package/@n8n/chat). Thanks to Wayne Simpson!

🚀 Features

• 📩 Connects to n8n via webhook (custom route)
• 💬 Fully client-side rendered widget UI
• 🎨 Custom branding and theming support
• 📎 Supports Markdown-formatted responses
• 🔗 Renders clickable links (target="_blank") from Markdown or HTML
• ⚙️ Easily embeddable in any website via HTML snippet

📦 Repository Contents

• chat-widget.js – Main JavaScript for rendering the chat UI and connecting to n8n
• chat-widget.css – Optional: custom styling (can be embedded or external)
• index.html – Example usage with configuration
• README.md – You're reading it

✨ Customizations

This widget includes the following ETH Library-specific customizations:

Uses marked.js to parse Markdown in bot responses

• Automatically adds target="_blank" and rel="noopener noreferrer" to all links
• Optional fallback that ensures HTML-based links are also modified correctly
• All links open in a new browser tab

🌐 Integration

To use this widget on a website:

1. Include Required Script (place it just before the tag.

<!-- Widget Configuration -->
<script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>
<script>
  window.ChatWidgetConfig = {
    webhook: {
      url: 'https://n8n.library.ethz.ch/webhook/01148f91-7a21-4f2c-b9fb-f9fdcaca0c1c/chat',
      route: 'general'
    },
    branding: {
      logo: 'https://avatars.githubusercontent.com/u/101881644',
      name: 'SLSP Manuals', // Your company name
      welcomeText: 'Hallo 👋, ich bin der Assistenzbot für den Confluence-Bereich SLSP Manuals.', //Welcome message
      responseTimeText: 'Dieser Bot kann Fehler machen. <a href="https://library.ethz.ch/footer/datenschutz.html" target="_blank">Datenschutz</a>' //Response time message
    },
    style: {
      primaryColor: '#00596D', //Primary color
      secondaryColor: '#007894', //Secondary color
      position: 'right', //Position of the widget (left or right)
      backgroundColor: '#ffffff', //Background color of the chat widget
      fontColor: '#333333' //Text color for messages and interface
    }
  };
</script>
<script src="https://cdn.jsdelivr.net/gh/eth-library/n8n-chat-widget-unlimited-d/chat-widget.js"></script>
<!-- Widget Script --> 

2. Configure the Widget

In your HTML page, configure/change webhook URL, branding and style settings.

3. Done!

Once embedded, the chat widget will connect to your configured n8n webhook and respond with formatted messages.

Notes

• This widget is designed to be served as a static asset (e.g. GitHub Pages, ETH web hosting, etc.)
• No backend required – logic is delegated to n8n workflows
• Works best when paired with Markdown-formatted responses from n8n
