The variable 'React' is defined but not utilized in the code

Here's the code snippet in question:

// tslint:disable
import * as React from 'react';
import { Input, InputProps } from '../atoms/Input/Input';
import { FormControl } from '../hoc/FormControl/FormControl';

export const FormInput = FormControl<InputProps>(Input);

Despite that, Typescript refuses to compile and raises this error:

'React' is declared but its value is never read.

Removing the line results in a different error:

Exported variable 'FormInput' references 'React.ComponentClass' from an external module "/node_modules/@types/react/index" which can't be named. [ts] Exported variable 'FormInput' uses 'React.StatelessComponent' from external module "/node_modules/@types/react/index" but cannot be named.

I have set declaration to true in tsconfig since it's necessary for this package.

Answer №1

Modify tsconfig.json

{
  "compilerOptions": {
     "jsx": "react"
  }
}

Answer №2

To resolve this issue, consider updating to TypeScript version 2.9 or later. This version introduces support for import types, allowing you to eliminate the need to import React while still being able to generate the declaration file.
