Willem,
Thank you for help, sorry but I'm beginner and still do not understand some
things, like how I'll wait for the event line finish and so run the
console.log?
I changed the code to this, its correct?
var csv;
var instream = fs.createReadStream(pathLog+req.params.file);
var outstream = new stream;
outstream.readable = true;
outstream.writable = true;
var rl = readline.createInterface({
input: instream,
output: outstream,
terminal: false
});
rl.on('line', function(lin) {
if(req.params.id != ''){
var re = new RegExp(req.params.id, 'i');
if(lin.match(re) != null){
var string = lin.substring(143,lin.length);
csv += ','+string;
}
}
});
res.set('Content-Type', 'application/octet-stream');
//console.log(csv);
//res.send(exports.csv);
});
