dear mr bubz,

const http = require('http');
const fs = require('fs').promises;

function genererGalleri(filnavne) {
    let html = '';
    for (let i = 0; i < 3; i++) {

        html += "<br> <img src = '" + filnavne[i] + "'>";

    }
    return html;
}

http.createServer(async(request, response) => {
    if (request.url === '/') {
        let filnavne = await fs.readdir(__dirname + '/filer');
        let html = genererGalleri(filnavne);
        response.writeHead(200, { "Content-Type": "text/html" });
        response.write(html);
    } else {
        try {
            let sti = __dirname + '/filer' + request.url;
            let filData = await fs.readFile(sti);
            response.writeHead(200);
            response.write(filData);
        } catch (e) {
            response.writeHead(404);
            response.write(e.name + ": " + e.message);
        }
    }
    response.end();
}).listen(8080);

console.log('Lytter på port 8080 ...');
