Yeah likewise I encountered the same problem 🤔

Hey @simoneb is there any work around you did about this to work?

I fiddled around with the installed package's package.json file but it wasn't by any means a robust solution. The fix should be fairly simple though, it's just a matter of getting the exports right in the package file.

same here

While this is not fixed, here is a temporary solution at least worked for me, btw i'm using yarn.

add this to your package.json file:

"resolutions": {
"mathjs": "11.11.0"
},

My less than ideal workaround to get it going before this is fixed is just loading via script tags <script src="https://cdn.jsdelivr.net/npm/[email protected]/lib/bundle.min.js" /> then you can use dfd globally.

I've created a draft PR (#604) with an implementation that works locally, but I'm not too happy with.

I'm new to package exports, so it's all a little blurry, hence why I'm keeping this one as a draft, but hopefully that's a start to fix the issues and could do with some help to finish it off.

Both for a new vite app and a new CRA app, I've linked the package locally with npm link danfojs, then used the following code in the root file:

import * as dfd from 'danfojs'
const s = new dfd.Series([1, 3, 5, undefined, 6, 8])
s.print()

Both apps run fine without runtime errors and display the series in the console.

However, types don't work, and I get the following error in CRA terminal output:

WARNING in ../danfojs/src/danfojs-browser/lib/bundle.esm.js 9:47-54
Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

WARNING in ../danfojs/src/danfojs-browser/lib/bundle.esm.js 12:44-51
Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

Has anyone figured out how to fix this issue? I was really looking forward to using this library in our production pipeline, but I can't remove Vite unfortunately and local hacks/fixes are a no go either.

I managed to get it work in ViteJS. I found out that the main problem is that they pointed out "module": "lib/bundle-esm.js" when it should actually be "module": "lib/bundle.esm.js". (the path is incorrect).

To get it working:

• Clone their code: https://github.com/javascriptdata/danfojs.git
• In package.json of my project I added the dependency: "danfojs": "file:///C:/GitRepo/danfojs/src/danfojs-browser"
• Change directory to danfojs/src/danfojs-browser
• Edit package.json line 7: "module": "lib/bundle.esm.js"
• Run yarn build:esm-bundle
• Done!

This hack works for me, instead of
import * as dfd from "danfojs"
do
import * as dfd from "danfojs/dist/danfojs-browser/src"
