• Version of Next.js: [9.0.0]

Hey @saeedghasemi72, this was from @types/next we don't have this type in our codebase. You can use https://github.com/zeit/next.js/blob/canary/packages/next-server/lib/utils.ts#L11 instead.

This is a common use case from version 8. I think that the upgrade guide https://github.com/zeit/next.js/blob/canary/UPGRADING.md should be amended to reflect the changes that need to be made.

For people looking for replacing NextFunctionComponent, you can replace it by:

• React.FC from "react" for classical components
• NextPage from "next" for page components that uses getInitialProps

Does any using typescript-eslint know how to fix @typescript-eslint/unbound-method?

It highlights MyComponent in MyComponent.getInitialProps = ...

const MyComponent: NextPage = () => {...}
MyComponent.getInitialProps = ...
