VistasTypeError: parse is not a function on csv-parse
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.

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.

Instead of using
const { parse } = require('csv-parse');
Try Following
const { parse } = require("csv-parse");

get the parse function it self in the csv-parse module by doing const {parse} = require("csv-parse");
and call .pipe(parse())
