outputs an object stream.
`javascript
var fs = require('fs');
var csv = require('rfc-csv');
// Creates a new CSV Transform stream
// The constructor takes one argument useHeader. If useHeader
// is true the first line will be skiped and a event will be emitted
var parser = csv(true);
// $cat file.csv:
// id,open,end\r\n
// 0,180.73,182.81\r\n
// 1,183.23,183.72\r\n
// 2,182.20,182.27
fs.createReadStream('file.csv').pipe(parser);
// Await header event
parser.once('header', function (header) {
console.log(header);
});
// Standard Readable stream event
parser.once('readable', function () {
// Read the first row there is an array of strings
var row = parser.read();
// RFC-4180 do not say anything about number type convertion, so that is
// something you must do, fortunately it is easy.
row = row.map(Number);
// Output row there is now an array of number
console.log(row);
});
