Creating a complete Electron.js application for SFTP file transfer involves several steps, and the code can be quite extensive. However, I can provide you with a simple example to get you started. This example uses the `ssh2-sftp-client` library for SFTP operations.
Before running the code, make sure to install the required npm packages:
```bash
npm install electron ssh2-sftp-client
```
Now, you can use the following sample code for a basic Electron.js SFTP file transfer application:
```javascript
// main.js
const { app, BrowserWindow } = require('electron');
const path = require('path');
let mainWindow;
function createWindow() {
mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true,
},
});
mainWindow.loadFile('index.html');
mainWindow.on('closed', function () {
mainWindow = null;
});
}
app.on('ready', createWindow);
app.on('window-all-closed', function () {
if (process.platform !== 'darwin') app.quit();
});
app.on('activate', function () {
if (mainWindow === null) createWindow();
});
```

<script>
const { ipcRenderer } = require('electron');
const Client = require('ssh2-sftp-client');
const sftp = new Client();
document.getElementById('connect').addEventListener('click', async () => {
try {
await sftp.connect({
host: 'your-sftp-server-host',
port: 22,
username: 'your-username',
password: 'your-password',
});
alert('Connected to SFTP');
} catch (err) {
console.error(err.message);
}
});
document.getElementById('upload').addEventListener('click', async () => {
try {
await sftp.put('path/to/local/file.txt', 'path/on/remote/server/file.txt');
alert('File Uploaded Successfully');
} catch (err) {
console.error(err.message);
}
});
</script>
</body>
</html>
```
Remember to replace `'your-sftp-server-host'`, `'your-username'`, and `'your-password'` with your actual SFTP server details.
This is a minimal example, and in a real-world application, you would want to handle errors more gracefully, implement more features, and structure your code better. Additionally, consider adding security measures such as securely storing credentials.
