I needed an async csv reader and originally tried @Pransh Tiwari's answer but couldn't get it working with await and util.promisify(). Eventually I came across node-csvtojson, which pretty much does the same as csv-parser, but with promises. Here is an example usage of csvtojson in action:

const csvToJson = require('csvtojson');

const processRecipients = async () => {
    const recipients = await csvToJson({
        trim:true
    }).fromFile('./recipients.csv');

    // Code executes after recipients are fully loaded.
    recipients.forEach((recipient) => {
        console.log(recipient.name, recipient.email);
    });
};
