TypeError: parse is not a function on csv-parse

Question

I ran into this issue after setting up a simple app using:

• node v16.13.2
• npm v8.1.2
• csv-parse v5.0.4
  On
• VSCode v1.63.2

Code is:

const parse = require('csv-parse');
const fs = require('fs');

const results = [];

fs.createReadStream('kepler_data.csv')
    .pipe(parse({
        comment: "#",
        columns: true,
    }))
    .on('data', (data) => {
        results.push(data);
    })
    .on('error', (err) => {
        console.log(err);
    })
    .on('end', () => {
        console.log(results);
        console.log('Done!');
    });

Running it resulted in:

index.js:7
    .pipe(parse({
          ^

Searching SO gave similar results but no actual solution.

Answer 1

Solution was simple. If parse or any other function is not recognized with node require, try getting the function itself as:

const { parse } = require('csv-parse');

Something worth noting it the color scheme that emphasizes the difference between the const parse color = white, and the usage of the function parse inside pipe = green.

And the colors without error where const { parse } is green, matchin the const call.
