ImageMod(options).then((filePath) => {
    //filePath is the absolute path of the modified image
});

const express = require('express');
const multer = require('multer');
const ImageMod = require('image-mod');
const path = require('path');
const app = express();

const upload = multer({ dest: path.join(__dirname, '/uploads') });

app.post('/upload', upload.single('picture'), async (req, res) => {
    const options = {
        file: req.file,
        imageType: 'png',
        imageQuality: 50,
    };
    const filePath = await ImageMod(options);
    return res.status(200).json({ success: true, filePath });
});
