Issue
In react-router-dom v6 the Route
components no longer have route props (history
, location
, and match
), and the current solution is to use the React hooks “versions” of these to use within the components being rendered. React hooks can’t be used in class components though.
To access the match params with a class component you must either convert to a function component, or roll your own custom withRouter
Higher Order Component to inject the “route props” like the withRouter
HOC from react-router-dom
v5.x did.
Solution
I won’t cover converting a class component to function component. Here’s an example custom withRouter
HOC:
const withRouter = WrappedComponent => props => {
const params = useParams();
// etc... other react-router-dom v6 hooks
return (
<WrappedComponent
{...props}
params={params}
// etc...
/>
);
};
And decorate the component with the new HOC.
export default withRouter(Post);
This will inject a params
prop for the class component.
this.props.params.id
