Writes [object Object] to csv file? about fast-csv HOT 3 CLOSED

Not totally sure. Most the examples have .pipe coming after .write.

There are tests for this so it should work in node 4 and 5 at least. https://github.com/C2FO/fast-csv/blob/master/test/formatting.test.js#L24

var ws = fs.createWriteStream("my.csv");
csv
   .write([
       {a: "a1", b: "b1"},
       {a: "a2", b: "b2"}
   ], {
        headers: true
        transform: function(row){
            return {
                A: row.a,
                B: row.b
            };
        }
   })
   .pipe(ws);

I'm running into this same problem working in node v6.1.0.

I think the two different write methods are being conflated. The write method in the inital example is the the write method that is provided by the node streams api, and should be called one row at a time.

The write report should be changed to.

function writeReport(file, data, cb){
    var existsAlready = fs.existsSync(file);
    var ws = fs.createWriteStream(file, {flags:'a'});
    var csvStream = csv.write(data, {
        headers: !existsAlready,
        includeEndRowDelimiter: true,
    });
    csvStream
        .on('finish', function(err){
            cb(err, file);
        })
        .pipe(fs.createWriteStream(file, {flags:'a'}));
}
