A lightweight JavaScript utility to block copying, pasting, cutting, and right-clicking.

copyguard-js provides a simple, framework-free way to prevent users from copying content, opening the context menu, or pasting into inputs. It can be used to secure form fields, protect sensitive data, or discourage content scraping.

• 🔒 Block Ctrl+C (Copy), Ctrl+V (Paste), Ctrl+X (Cut)
• 🖱️ Disable right-click (context menu)
• 🧠 Optional onViolation callback for custom behavior/logging
• 🪶 Zero dependencies

npm install copyguard-js

Then in your JavaScript:

import Copyguard from 'copyguard-js';

Copyguard.enable({
  blockCopy: true,
  blockPaste: true,
  blockCut: true,
  blockRightClick: true,
  onViolation: (type) => {
    console.warn(`Blocked: ${type}`);
  }
});

<script src="https://unpkg.com/copyguard-js@latest/dist/copyguard.min.js"></script>
<script>
  Copyguard.enable({
    onViolation: (type) => {
      alert(`🚫 ${type} blocked`);
    }
  });
</script>

Copyguard.enable({
  blockCopy: true,
  blockPaste: true,
  blockCut: true,
  blockRightClick: true,
  onViolation: (action) => {
    console.log(`User tried to: ${action}`);
  }
});

// To disable protection:
Copyguard.disable();
