如何在nodejs中验证csv文件中的数据？

npm install csv-parser joi

const fs = require('fs');
const csv = require('csv-parser');
const Joi = require('joi');

// 定义验证规则
const schema = Joi.object({
  name: Joi.string().required(),
  age: Joi.number().integer().min(0).required(),
  email: Joi.string().email().required()
});

// 读取CSV文件并验证数据
fs.createReadStream('data.csv')
  .pipe(csv())
  .on('data', (row) => {
    const { error } = schema.validate(row);
    if (error) {
      console.error(`Validation error: ${error.message}`);
    } else {
      console.log('Validation passed:', row);
    }
  })
  .on('end', () => {
    console.log('CSV file successfully processed');
  });
