ES modules syntax support?

[sekhavati]

Hello 👋 We use TypeScript throughout our projects. Typically we use ES modules syntax (import/export) to load our modules, this then gets boiled down to CommonJS style (require) after the compiler has run.

It seems this module does not support use of the import/export syntax, is it suppose to?

For example we encounter these sorts of errors:

Working example:

const webhooks = require("gocardless-nodejs/webhooks");

webhooks.parse(...); // ok

Broken example:

import webhooks from "gocardless-nodejs/webhooks";

webhooks.parse(...); // => Runtime TypeError: Cannot read properties of undefined (reading 'parse')

Just stumbled across this issue as we are having the same issue - feels strange that a package like this would not support ES Modules syntax 🤔

Hey Both, I'm sure you've solved your issues but this is how you'd go about using the library and get the types support.

import { GoCardlessClient } from 'gocardless-nodejs/client';
import Constants from 'gocardless-nodejs/constants';

// Initialise the client.
const gocardless = new GoCardlessClient(
  SECRET,
  Constants.Environments.Live OR Constants.Environments.Sandbox,
);

Hi, Thanks for adding your reply - I've been able to get my integration working with Nuxt 3 locally as a result.

In a dev env, it all works great and a payment journey is completed successfully but when I deploy to Netlify, I get an error at the billing-request action stage which I think maybe it's as a result of importing the package as an ESM module.

Apr 18, 12:52:32 PM: d1f10929 ERROR  [nuxt] [request error] [unhandled] [500] Cannot find module '/var/task/node_modules/gocardless-nodejs/client' imported from /var/task/chunks/billing-request.post.mjs
Did you mean to import gocardless-nodejs/client.js?

Would you perhaps be able to comment on this and make a suggestion as to what I could try to do to fix it? I contacted their support but I've not had a response.

TIA

Did you managed to solve this ? maybe we can close this issue then, thanks @sohilpandya
