示例1: parse

console.log('parsing csv file', filePath);
var plaqueList = [];
var parser = parse({ delimiter: ',' }, (err, data) => {
if (err) {
rej(err);
return;
}
var cols = data[0];
for (var index = 1; index < data.length; index++) {

if (!newPlaque.main_photo
|| !newPlaque.erected
|| newPlaque.erected.startsWith('16')

plaqueList.push(newPlaque);
};

});
fs.createReadStream(filePath).pipe(parser);
});示例2: convertCSVToJSON
