fs.readFile wont let to end the connection

router.get('/', (req, res) => {`fs.readFile('/index.html', (err, data) => {` `if (err) throw err;` `var $ = cheerio.load(data);` `$('a#archive').attr('href', baseURL+'/archive');` `res.status(200).end($.html());` `});` });​"fs.readFile()" makes the browser wait although the data was sent (the browser writes "Waiting for localhost..."),when i look at the "Network" tab in "Inspect Elements" i see the packet with the file's data i've sent from the server side but it wont show it because the browser is waiting for the server to end the connection.
