Updating Chartjs-node-canvas to support Chart.js 4.X

[Bhager01]

I am working on updating the following library to support Chart.js 4.X:

https://www.npmjs.com/package/chartjs-node-canvas

I am not the original author of this library. Currently, I am getting the following error:
TypeError: this._chartJs is not a constructor

I believe the line of code in the library causing this error is:
const chart = new this._chartJs(context, configuration);

For reference this is how _chartJs is defined:
private readonly _chartJs: typeof ChartJS

Does anyone have a suggestion how to fix this? In general, is there a strategy utilizing the 4.x migration guide to find all potential breaking changes in this library? Thank you the help!

@Bhager01 have the same issue? Did you solve it?

Denis, Unfortunately I was never able to resolve this. I am sure Chartjs-node-canvas could be updated, I just didn't have the time / knowledge to do it. For now I am still using Chart.js 3.x. Best of luck if you figure out a solution!

I haven't looked at the project itself, but I noticed an issue about upgrading and someone posted a working way with another canvas library on node to use chart.js on the server:
