I'm new to TypeScript and I'm currently setting up a React application with Next.js, Redux, Jest, etc. However when running the application I'm getting a Type error which stops the application.
It seems problem is down to the props I'm passing in. This component is wrapped with a HOC 'withRouter' component from next which returns the same component with route information, i.e. {router: {pathname: /}}
My Component (Logo.tsx)
import React, { SFC } from 'react';
import { withRouter, WithRouterProps } from 'next/router';
import LogoStyled from './Logo.styled';
interface LogoProps {
router: { pathname: string };
}
const Logo: SFC<LogoProps & WithRouterProps> = ({ router }) => {
const { pathname } = router;
return pathname === '/' ? (
<LogoStyled>Home</LogoStyled>
) : (
<LogoStyled>Not Home</LogoStyled>
);
};
export default withRouter(Logo);
My Jest Test (Logo.test.tsx)
import React from 'react';
import { shallowToJson } from 'enzyme-to-json';
import 'jest-styled-components';
import { shallowWithTheme, mountWithTheme } from '../../../tests/testHelpers';
import Logo from './Logo';
const home = { pathname: '/' };
const about = { pathname: '/about' };
describe('Logo', () => {
it('should render correctly', () => {
const element = shallowWithTheme(<Logo router={home} />);
expect(shallowToJson(element)).toMatchSnapshot();
});
it(`should display 'Home' for homepage`, () => {
const element = mountWithTheme(<Logo router={home} />);
expect(element.text()).toBe('Home');
});
it(`should display 'Not Home' for homepage`, () => {
const element = mountWithTheme(<Logo router={about} />);
expect(element.text()).toBe('Not Home');
});
});
Results in Error:
components/atoms/Logo/Logo.test.tsx:13:43 -
error TS2322: Type '{ router: { pathname: string; }; }'
is not assignable to type 'IntrinsicAttributes & Pick<LogoProps &
WithRouterProps<Record<string, string | string[]>>, never> & { children?: ReactNode; }'.
Property 'router' does not exist on type 'IntrinsicAttributes &
Pick<LogoProps & WithRouterProps<Record<string, string | string[]>>,
never> & { children?: ReactNode; }'.
I'm guessing this quite an obvious thing I'm missing, but I'm struggling to make sense out of this at the moment. Thank you for any help you can give.
