When utilizing create-next-app, an error may occur stating that the produced JSX.Element cannot be assigned to a variable

After creating a new project with TypeScript using create-next-app, I encountered an error in the default homepage when opened in my IDE (WebStorm).

The error message reads: "Initializer type () => JSX.Element is not assignable to variable type NextPage."

Despite this error, the project still builds and runs successfully using yarn dev.

I need help figuring out what's causing this issue. Can anyone assist?

Answer №1

After reinstalling Webstorm, I encountered unexpected issues and had to re-enable the TypeScript language service in settings.

Answer №2

House is considered a React component and classified as React.FC to accurately represent its nature as a component within the React framework.

const House: React.FC<{}> = () => {

return (
    // ...
  )
}

The code compiles without errors because during compilation, it is converted to javascript, where types and interfaces are not mandatory.
