chartjs-node-canvas using webpack

[yo34]

Hi,

I using this conf where running webpack :

export default {
  entry: './server.js',
  mode: "production",
  devtool: 'source-map',
  //externals: [nodeExternals({allowlist: [/\.(?!(?:jsx?|json)$).{1,5}$/i],})],
  // la allowlist spécifie les packages qui vont etre dans le bundle
  externals: [nodeExternals({allowlist: [ ...,  'chart.js', 'chartjs-adapter-moment', 'chartjs-node-canvas', 'chartjs-node-canvas']})],

I get the following error where I build the application :

WARNING in ./node_modules/chartjs-node-canvas/dist/freshRequire.js 6:25-46
Critical dependency: the request of a dependency is an expression
 @ ./node_modules/chartjs-node-canvas/dist/index.js 4:23-48

Hi there!

So I have not used webpack much and am not familiar with that error or why there is a need for webpack on Nodejs actually (is it not meant for browser based js?). From my limited understanding, I assume it is complaining about the 'use' of require in that bit of code, since it is a commonjs module thing? I have not yet added support for esm in this lib, and it will be non-trivial given the node-canvas memory management concerns, but it is on the roadmap.

Not sure if this helped? If it is not related to my assumption maybe you can guide me a bit on the details of why/ how it is breaking?
