Having trouble with triggers: Unable to locate the module 'csv-parse/sync' for parsing

Question

Having trouble with triggers: Unable to locate the module 'csv-parse/sync' for parsing

Currently, I am utilizing Firebase functions to create an API that is capable of parsing CSV files.

However, whenever I attempt to utilize csv-parse/sync instead of csv-parse, my deployment to Firebase Functions encounters a failure with the subsequent error message:

Error: Error parsing triggers: Cannot find module 'csv-parse/sync''
Require stack:
- /Users/xxx/Programming/xxx/Firebase Functions/xxx/functions/lib/index.js
- /usr/local/lib/node_modules/firebase-tools/lib/deploy/functions/runtimes/node/triggerParser.js

Consider running "npm install" in your functions directory before proceeding with deployment.

I have implemented it using:

import { parse } from 'csv-parse/sync';

Subsequently utilized in code as follows:

interface EventData {
    update: string;
    id: string;
    title: string;
    description: string;
    category: string;
    ages: string;
    place: string;
    placeCoordinate: string;
    startDate: string;
    startTime: string;
    length: string;
    url: string;
    arrName: string;
  }

let events: Array<EventData> = []
const headers = ["update", "id", "title", "description", "ages", "place", "placeCoordinate", "startDate", "startTime", "length", "url", "arrEpost", "arrName", "validated", "skugg"]
try {
    events = parse(text, {columns: headers, from: 6, quote: "\"", delimiter: ";", ltrim: true, rtrim: true})
}...

To install, I navigated to my /functions folder and executed

npm install --save csv-parse

Proceeded with deployment at the root folder using

firebase deploy

My query lies in whether this is a framework issue, a problem with Firebase, or if I might be making an error myself. Utilizing "csv-parse" without sync works seamlessly. Strangely, while importing in Visual Studio Code, both instances seem fine, but issues arise when deploying with "sync". Attempts such as cleaning the node_modules folder, reconstructing the package-lock.json file, upgrading to the latest version of firebase tools have all yielded no success.

A similar inquiry has been directed to the framework project's issue page: https://github.com/adaltas/node-csv/issues/323

Answer №1

In a Typescript project, you have the option to accomplish this by:

import parse from 'csv-parse/sync';

or

import {parse} from 'csv-parse/lib/sync';

Personally, I found that either of the options below worked well when using node.js (as per guidance from Jeff Paredes):

import parse from 'csv-parse/lib/sync';

const parse = require('csv-parse/lib/sync');

It appears that the file structure within the node_modules directory has been modified. Now, instead of finding sync.js directly in the csv-parse folder, it can be located within csv-parse/lib.

After experimenting with different methods, I found the perfect solution using

<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b7d4c4c1f78199849984">[email protected]</a>

. Despite unsuccessful attempts with just csv-parser, combining it with the following code made everything work smoothly:

import { parse } from "csv-parse/sync";

Here is an example of how it can be used:

import * as fs from "fs";
import { parse } from 'csv-parse/sync';

const csvPath = "./data/users.csv";

type UserRow = {
  id: number;
  name: string;
};

const csvContent = fs.readFileSync(csvPath, "utf-8");
const rows: UserRow[] = parse(csvContent, {
  columns: true,
  skip_empty_lines: true,
});

console.log(rows);

In addition, adding

"moduleResolution": "node"

to the compilerOptions in the tsconfig.json file was necessary for successful implementation.

Currently, the best way to implement node-csv is by using either yarn add csv, pnpm install csv, or npm install csv in your terminal.

After installing, you can simply import the parse function from 'csv' in your code like this:

import { parse } from 'csv'

And that's all there is to it!
