[Bug]: Charts are auto-registered in develop build, but not in production build

Current and expected behavior

Disclaimer:

I'm not fully into the ecosystem, so I might get some ideas wrong. I'll explain to the best of my knowledge.

Summary:

typedcharts.tsx:33 (and after) states it has no side effects ( __PURE__) , but in reality there are ( charts get registered ) .
As a result, charts show on develop builds, but production build crashes entirely.

Details:

Below is an extract of typedCharts.tsx, around 33

function createTypedChart<T extends ChartType>(
  type: T,
  registerables: ChartComponentLike
) {
  ChartJS.register(registerables);

  return forwardRef<ChartJSOrUndefined<T>, Omit<ChartProps<T>, 'type'>>(
    (props, ref) => <Chart {...props} ref={ref} type={type} />
  ) as TypedChartComponent<T>;
}

export const Line = /* #__PURE__ */ createTypedChart('line', LineController);
...

Problem

The last line states it has no side effects. This cases deletion during the tree-shaking process in production builds (at least as much as I understand).

build system:

• webpack:
  • devserver: Charts don't need registration in user code. Everything works fine without registration.
  • production build: Charts don't need registration in user code. Everything works fine without registration.　
• vite:
  • devserver ( vite --mode devlocal ): Charts don't need registration in user code. Everything works fine without registration.
  • production build (vite build --mode production): Charts need registration in user code. App crashes without registration.

Reproduction

At the time of writing I cannot provide a reproducing example. I'll try to add it during the days.

chart.js version

3.9.1

react-chartjs-2 version

4.3.1

Possible solution

Either of the following

• Remove /* #__PURE__ */ from those lines to explicitly tell about the side effects.
• Remove the register command for each chart (probably only with major version bump)

Note: regarding both possible solutions, I cannot say if they cause problems somewhere else.
