Error encountered in TypeScript when using D3.js V3 with angular 2+ for fill styling

When attempting to incorporate this example into Angular 6, I came across an issue in the implementation process. The problem arises in the 'fill' style setting within TypeScript.

Within the change(data) function:

Even after trying to include the <any> tag, the issue remains unresolved.

The error messages provided by Angular and VSCode are as follows:

: error TS2345: Argument of type '"fill"' is not assignable to parameter of type '{ [key: string]: string | number | boolean | ((datum: any, index: number, outerIndex: number) => ...'.
No overload matches this call.
  Overload 1 of 4, '(name: string, value: Primitive, priority?: string): Selection<any>', gave the following error. ....(omitted)

Answer №1

While I am uncertain about the specifics of D3 typings, one way to bypass the error is by simply considering the slice object as any:

(slice as any).enter().append('path').style('fill', function () { .... })
          ^
