What could be causing the type error in TypeScript that WebStorm is displaying?

Currently, I am immersed in a Nextjs project utilizing

<span class="__cf_email__" data-cfemail="83c0ebe2f1f7ade9f0c3b7adb0adb3">[email protected]</span>
and
<span class="__cf_email__" data-cfemail="b5c7d0d4d6c198d6ddd4c7c1dfc69887f5809b879b85">[email protected]</span>
. Although the project compiles successfully, WebStorm throws a type error.

In this context, here's a Minimal Reproducible Example (MRE) related to Nextjs:

// pages/index.tsx
import { Chart, registerables }
import { Line } from 'react-charts-j2'

const Index () => {
  const chart = {
    data: {
      labels: ['foo', 'bar', 'foobar', 'foobaz']
      datasets: [
        {
          label: 'Foo',
          data: [0, 1, 2, 3]
        }
      ]
    }
  }
  return (
    <Line data={chart.data} />
  )
}

I attempted specifying data and labels types for Line like this:

<Line<Array<number>, string>
, but that approach failed. The IDE highlights the following error message:

Type {datasets: {data: number[], label: string}[], labels: string[]} is not assignable to type ChartData<"line", TData, TLabel>

For reference, the working environment details are as follows:

  • Nextjs: 13.0.6
  • React: 18.2.0
  • Node: 18.12.1
  • Typescript: ^5.0.4

The question remains, could this issue be stemming from my IDE setup or my code implementation?

Answer №1

After troubleshooting, I discovered that the problem was related to my IDE. Simply toggling the option for Show project errors in the Settings menu (

Settings -> Languages & Frameworks -> TypeScript
) resolved the error.
