Enables pasting images directly into the WYSIWYG editor from clipboard, including screenshots and copied image files.

Changes

Image paste handler: Added paste event listener that detects image data in clipboard, converts to base64 via FileReader, and inserts at cursor position
Toolbar image button: Added image upload capability with file picker (accepts image/*)
Format support: Added 'image' to allowed Quill formats array
React optimization: Memoized handlers with useCallback and useMemo, proper event cleanup in useEffect

Implementation

// Paste event handler
useEffect(() => {
  const quill = quillRef.current?.getEditor();
  if (!quill) return;

  const handlePaste = (e) => {
    const items = e.clipboardData?.items;
    for (let i = 0; i < items?.length; i++) {
      if (items[i].type.indexOf('image') !== -1) {
        e.preventDefault();
        const file = items[i].getAsFile();
        const reader = new FileReader();
        reader.onload = (event) => {
          const range = quill.getSelection(true);
          quill.insertEmbed(range.index, 'image', event.target.result);
          quill.setSelection(range.index + 1);
        };
        reader.readAsDataURL(file);
        break;
      }
    }
  };

  quill.root.addEventListener('paste', handlePaste);
  return () => quill.root.removeEventListener('paste', handlePaste);
}, []);

Images are embedded as base64 data URLs, requiring no backend changes.

Demo

Users can now:

Paste images with Ctrl+V / Cmd+V
Click toolbar image button to upload files
Paste screenshots directly into content

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

backend

Triggering command: node /home/REDACTED/work/noodlenook/noodlenook/frontend/node_modules/.bin/vite (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled

Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Add the ability to paste images into the WYSIWYG editor
