Hi everyone,
I'm a newbie in nodejs and express, so i'm trying to generate one CSV file
reading a content of one log file, something like this:
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,csv) {
var csv;
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);
The real problem is, I declared the variable csv and in the event line I'm
incrementing that but in the console.log return undefined.
Thank you!
