Those are great to deal with CSV in a production system.

这些非常适合在生产系统中处理CSV。

I like to keep things simple when I don’t have performance in mind. For example, for a one-time parsing of CSV that I had to do to consolidate my backend systems.

当我不考虑性能时，我喜欢保持简单。 例如，对于一次CSV解析，我不得不整合后端系统。

To do so, I used , a package that exposes the csv-parser functionality to a simple async/await interface.

为此，我使用了 ，这是一个将csv-parser功能公开给简单的async / await接口的软件包。

Install it using npm install neat-csv and require it in your app:

使用npm install neat-csv安装它，并在您的应用程序中要求它：

const neatCsv = require('neat-csv');

then load the CSV from the filesystem and invoke neatCsv passing the content of the file:

然后从文件系统加载CSV并调用neatCsv传递文件内容：

const fs = require('fs')fs.readFile('./file.csv', async (err, data) => {  if (err) {    console.error(err)    return  }  console.log(await neatCsv(data))})

Now you can start doing whatever you need to do with the data, which is formatted as a JavaScript array of objects.

现在，您可以开始处理数据，该数据被格式化为JavaScript对象数组。
