Spin up temporary webserver to handle callback from browser

callback.js

const http = require('http');
const url = require('url');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/html');
    try {
        let parsedUrl = url.parse(req.url, true);
        console.log('query', parsedUrl.query);
        let accountId = parsedUrl.query.account_id;
        res.end('Much success, you can close window now');
        console.log('Account ID:', accountId);
        // doSomething(accountId);
        server.close();
    } catch (e) {
        console.log('Unexpected error: ', e);
        res.statusCode = 400;
        res.end('It\'s a scam!');
        return;
    }
});

server.listen(port, hostname, () => {
    console.log(`Server running at http://${hostname}:${port}/`);
});
