Step 1: Install Dependencies
Before diving in, install the required libraries:

npm install @tiptap/react @tiptap/starter-kit @tiptap/extension-mention

Step 2: Create a Basic RichText Editor

Start by creating a RichTextEditor component. Here’s a simple implementation:

import { useEditor, EditorContent } from '@tiptap/react';  

import StarterKit from '@tiptap/starter-kit';  

export const RichTextEditor = ({ content, onChange }) => {  
  const editor = useEditor({  
    extensions: [StarterKit],  
    content: content,  
    onUpdate: ({ editor }) => {  
      onChange(editor.getHTML());  
    },  
  });  
  return <EditorContent editor={editor} />;  
};

Step 3: Add Mentions

Mentions enhance user interactivity, especially in chat or collaborative applications. To implement them:

Install and Configure the Mention Extension

Modify the RichTextEditor component to include the Mention extension:

import Mention from '@tiptap/extension-mention';  

export const RichTextEditor = ({ content, onChange, mentions }) => {  
  const editor = useEditor({  
    extensions: [  
      StarterKit,  
      Mention.configure({  
        HTMLAttributes: { class: 'mention' },  
        suggestion: {  
          items: ({ query }) =>  
            mentions.filter(item => item.display.toLowerCase().includes(query.toLowerCase())).slice(0, 5),  
          render: () => {  
            let component;  
            let popup;  
            return {  
              onStart: (props) => {  
                popup = document.createElement('div');  
                popup.className = 'mention-popup';  
                document.body.appendChild(popup);  
                component = {  
                  updateProps: () => {  
                    popup.innerHTML = `  
                      <div class="items">  
                        ${props.items.map(item => `  
                          <button class="item ${item.selected ? 'is-selected' : ''}">${item.display}</button>  
                        `).join('')}  
                      </div>  
                    `;  
                  },  
                  destroy: () => popup.remove(),  
                };  
                popup.addEventListener('click', (e) => {  
                  const button = e.target.closest('button');  
                  if (button) {  
                    const index = Array.from(popup.querySelectorAll('.item')).indexOf(button);  
                    props.command({ id: props.items[index].id, label: props.items[index].display });  
                  }  
                });  
                component.updateProps();  
              },  
              onExit: () => component?.destroy(),  
            };  
          },  
        },  
      }),  
    ],  
    content,  
    onUpdate: ({ editor }) => onChange(editor.getHTML()),  
  });  
  return <EditorContent editor={editor} />;  
};

Step 4: Style the Mentions Popup

Mentions should be visually distinct. Add the following styles to enhance usability:

.mention-popup {  
  background: white;  
  border-radius: 8px;  
  box-shadow: 0px 2px 8px rgba(0, 0, 0, 0.1);  
  padding: 8px;  
  position: absolute;  
  z-index: 1000;  
}  
.mention-popup .items {  
  display: flex;  
  flex-direction: column;  
}  
.mention-popup .item {  
  padding: 8px;  
  cursor: pointer;  
  border-radius: 4px;  
}  

.mention-popup .item:hover,  
.mention-popup .item.is-selected {  
  background: #f0f0f0;  
}

Step 5: Edge Cases I Faced During Implementation

Cursor Jumping: To avoid cursor jumping while typing, ensure content updates preserve the cursor’s position:

const editor = useEditor({  
  extensions: [StarterKit],  
  content,  
  onUpdate: ({ editor }) => {  
    const selection = editor.state.selection;  
    onChange(editor.getHTML());  
    editor.commands.setTextSelection(selection);  
  },  
});

Placeholder Not Visible:

Use the Placeholder extension to display a hint when the editor is empty:

import Placeholder from '@tiptap/extension-placeholder';  
const editor = useEditor({  
  extensions: [  
    StarterKit,  
    Placeholder.configure({ placeholder: 'Type something...' }),  
  ],  
});

Mention Suggestions Not Showing: Check the suggestion.items method to ensure it filters and returns the expected list.

Step 6: Integrate into Your App

Wrap the editor in a modal or form component to make it part of a larger feature, such as notifications or comments. Here’s an example:

import React from 'react';  

const NotificationForm = ({ mentions, onSubmit }) => {  
  const [content, setContent] = React.useState('');  
  return (  
    <form onSubmit={() => onSubmit(content)}>  
      <RichTextEditor content={content} onChange={setContent} mentions={mentions} />  
      <button type="submit">Send</button>  
    </form> 
  );  
};
