const express = require('express');
const multer = require('multer');
const fs = require('fs');

const app = express();
const port = 3000;

// Middleware to parse JSON requests
app.use(express.json());

// Define the storage for multer
const storage = multer.memoryStorage(); // Store files in memory as buffers

// Set up multer with the storage configuration
const upload = multer({ storage: storage });

// POST route to receive base64-encoded image data
app.post('/upload-image', upload.single('image'), (req, res) => {
  try {
    // Access the uploaded image from req.file.buffer
    const imageBuffer = req.file.buffer;

    // Generate a unique filename (you can implement your own logic here)
    const fileName = `${Date.now()}.png`;

    // Write the buffer to a file (in this case, a PNG image)
    fs.writeFileSync(fileName, imageBuffer);

    // You can now process or store the image as needed
    // For example, you can send a success response
    res.status(200).json({ message: 'Image uploaded successfully' });
  } catch (error) {
    console.error(error);
    res.status(500).json({ error: 'An error occurred' });
  }
});

app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});
