Read Image (PNG/JPEG) From Disk and Convert it to base64-encoded string on Node Server

convertImgToBase64.js

import fs from 'fs';
import path from 'path';

const convert = (imgPath) => {
    // read image file
    fs.readFile(imgPath, (err, data)=>{
        // error handle
        if(err) {
            throw err;
        }
        
        // get image file extension name
        const extensionName = path.extname(imgPath);
        
        // convert image file to base64-encoded string
        const base64Image = Buffer.from(data, 'binary').toString('base64');
        
        // combine all strings
        const base64ImageStr = `data:image/${extensionName.split('.').pop()};base64,${base64Image}`;
    })
}

Thank you you helped me a lot😘

Thanks for putting this out. Saved me a lot of trouble. ❤️

Thanks for this code conversion! Though it looks a bit difficult to me as I am a beginner in coding. I've started to learn more about image formats, compression, and conversion... Check this post to learn more about PNG and is PNG a lossless compression. Thanks again for your help!
