how to show shell script report to in html using nodejs

I need to show shell script report to html using node js

What I did:

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var exec = require('child_process').exec;
var rexec = require('remote-exec');
var fs = require('fs');

var cmds = [
           'sh /indexer.sh'
       ];
 var connection_options = {
     port: 22,
     username: 'root',
     privateKey: fs.readFileSync('/home/raj2/.ssh/id_rsa'),
     passphrase: 'gworks.mobi',
     stdout: fs.createWriteStream('./views/output.txt'),
     stderr: fs.createWriteStream('./views/error.txt')
 };

 var hosts = [
     '10.1.2.50'
 ];

 app.post('/nodeapp', urlencodedParser, function (req, res) {
   //  res.send('You sent the name "' + req.body.selectpicker + '".');
   //console.log( req.body.selectpicker);

   //res.send('You sent the name "' + req.body.selectpicker + '".');

   if (req.body.selectpicker == "reindex") {

       var cmds = [
           'sh /indexer.sh'
       ];
       res.send('reindex Process  Started');

       rexec(hosts, cmds, connection_options, function (err, stdout, stderr) {
           if (err) {
               console.log(err);
               res.send(req.body.err)
           } else if (stdout) {
               console.log('stdout!!');
               res.send(req.body.stdout)
           } else {
               console.log('Great Success!!');
           }
       });

   }

   });

I have call remote machine to run the shell script and I print the shell report to console, but I need to show this status to front end(html).

I have write the shell report to file(output.txt) so i follow below way its not works for me.

fs.readFile('./views/output.txt', function (err, html) {
    if (err) {
        throw err;
    }
    http.createServer(function (request, response) {
        response.writeHeader(200, {"Content-Type": "text/html"});
        response.write(html);
        response.end();
    });
});

Suggest me How to show shell report to html using nodejs or Any other best way to do this.
