electron-content-protection

A lightweight native module to enforce content protection/anti-screenshotting on Electron windows using Windows APIs. On macOS/Linux, it gracefully falls back to a dummy implementation so it does not crash or break compiling.

Installation

npm install electron-content-protection

Publishing to NPM

To publish this package to NPM:

1. Log in to NPM:

   npm login

2. Publish:

   npm publish

   Note: Only files defined in the files array in package.json will be uploaded. The local build/ directory is automatically ignored, allowing npm to build the module from source for each consumer's platform.

Usage in Electron

const { setWindowExcludeFromCapture } = require('electron-content-protection');

// Fallback to native on Windows
if (process.platform === 'win32') {
  try {
    const hwnd = win.getNativeWindowHandle();
    const result = setWindowExcludeFromCapture(hwnd);
    console.log('Native content protection applied:', result);
  } catch (error) {
    console.error('Failed to apply native content protection:', error);
  }
}
