I ran into this issue after setting up a simple app using:
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({
^
TypeError: parse is not a function

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.
Thanks man you saved my day. One thing I just want to know that which color theme you're using so that I can know the same difference that you found out in this problem.
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())
What worked for me was changing from "csv-parse" to "csv-parser"
Use this in package.json
"csv-parser": "^3.0.0"
Instead of:
"csv-parse": "v5.0.4"
const {parse} = require('parse')
instead of const parse = require('parse')
OR"csv-parse": "^3.0.0"
of "csv-parse": "^5.3.0"
