title: Use csv-parser to only return file headers
body: <p>I'm looking at the NPM package csv-parser that parses csv files to JSON. Based on the example provided, you can read a csv file row by row in the following manner:</p>
  <pre><code>fs.createReadStream('data.csv')
    .pipe(csv())
    .on('data', (rowData) =&gt; console.log(rowData))
    .on('end', () =&gt; { console.log(&quot;done reading the file&quot;) });
  </code></pre>
  <p>Is there any way I can only return the header values of the CSV file instead?</p>
