Thanks asynqronic,
Following code,
*profiles3.js*
module.exports = function(callback){
var spawn = require('child_process').spawn,
ls = spawn('ls', ['-lh', '/usr']);
ls.stdout.on('data', callback);
ls.stderr.on('data', callback);
ls.on('exit', callback);
};
*index.js*
exports.index = function(req, res){
profiles3(function(data){
res.writeHead(200, {
"Content-Type": "text/plain",
"Content-Length": data.length
});
res.end(data, 'uft-8');
});
};
Giving following error,
Express server listening on port 3000
GET / 200 15ms
http.js:687
throw new Error('Can\'t render headers after they are sent to the
client.'
^
