Error module stream in ESM build

[Nisgrak]

Hi!

I'm using this lib in 5.0.6 version with Vite (using the ESM build) and have an error when load the Parser:

browser-external:stream:3 Uncaught Error: Module "stream" has been externalized for browser compatibility and cannot be accessed in client code.
    at Object.get (browser-external:stream:3)
    at json2csv.esm.js:1870

I'm not using the Streaming API, only the synchronous so don't know if it's possible to disabled.

Thanks!

Maybe you can set this option in vite? https://vitejs.dev/config/#optimizedeps-exclude

Or the rollup options here https://vitejs.dev/config/#build-rollupoptions

I'm trying with this, but happend the same error

optimizeDeps: {
    exclude: ["stream"]
  },

Any disclosure for that? I'm facing the same issue.

Can you reproduce the issue and upload it as a repo for us to look at?

I found a temporary workaround using umd instead

import { parse } from 'json2csv/dist/json2csv.umd'

Using a resolve.alias configuration of { "json2csv": "json2csv/dist/json2csv.umd.js" } works as well and does not break the TypeScript definitions.

The problem happens when packaging the library for frontend since it uses some Node libraries. Like the stream library.

In v6 this, will be changed to minimize the node-specific parts and we should reconsider how we expose the different APIs to clearly separate node APIs from standard JS APIs

import { parse } from 'json2csv/dist/json2csv.umd'

works for me

[juanjoDiaz]

Another solution could be to import directly the module that you want to use. Something like

import parser from 'json2csv/JSON2CSVParser'

Closing since a workaround has been given.

took long enough....

v6, which has moved to a new repo and broken down into smaller packages is in esm.

Still same issue with vite and json2csv@v6 (latest). But the UMD workaround still works.
