Answer 1

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

HOC withRouter TypeScript version with generic Params
withRouter.tsx
import { ComponentType } from 'react';
import { useLocation, useNavigate, useParams } from 'react-router-dom';
export interface WithRouterProps<T = ReturnType<typeof useParams>> {
history: {
back: () => void;
goBack: () => void;
location: ReturnType<typeof useLocation>;
push: (url: string, state?: any) => void;
}
location: ReturnType<typeof useLocation>;
match: {
params: T;
};
navigate: ReturnType<typeof useNavigate>;
}
export const withRouter = <P extends object>(Component: ComponentType<P>) => {
return (props: Omit<P, keyof WithRouterProps>) => {
const location = useLocation();
const match = { params: useParams() };
const navigate = useNavigate();
const history = {
back: () => navigate(-1),
goBack: () => navigate(-1),
location,
push: (url: string, state?: any) => navigate(url, { state }),
replace: (url: string, state?: any) => navigate(url, {
replace: true,
state
})
};
return (
<Component
history={history}
location={location}
match={match}
navigate={navigate}
{...props as P}
/>
);
};
};
MyClass.tsx
import { Component } from 'react';
import { withRouter, WithRouterProps } from './withRouter';
interface Params {
id: string;
}
type Props = WithRouterProps<Params>;
class MyClass extends Component<Props> {
render() {
const { match } = this.props;
console.log(match.params.id); // with autocomplete
return <div>MyClass</div>;
}
}
export default withRouter(MyClass);

Here's the code example I'm using in my project to get the id from the URL:
import React from 'react'
import {Button} from 'antd'
import {useParams} from 'react-router-dom'
const DeleteUser = () => {
const {id} = useParams()
const handleDelete = async () => {
// handle delete function
}
return (
<Button onClick={handleDelete}>Delete User</Button>
)
}
export default DeleteUser

If you would like to use a class, then you will need to wrap it with the withRouter. I provide an example below:
This is my class for the movie form:
class MovieForm extends Form {
state = {
data: {
title: "",
genreId: "",
numberInStock: "",
dailyRentalRate: ""
},
genres: [],
errors: {}
};
schema = {
_id: Joi.string(),
title: Joi.string()
.required()
.label("Title"),
genreId: Joi.string()
.required()
.label("Genre"),
numberInStock: Joi.number()
.required()
.min(0)
.max(100)
.label("Number in Stock"),
dailyRentalRate: Joi.number()
.required()
.min(0)
.max(10)
.label("Daily Rental Rate")
};
componentDidMount() {
const genres = getGenres();
this.setState({ genres });
// const movieId = this.props.match.params.id;
const movieId = this.props.params.id;
if (movieId === "new") return;
const movie = getMovie(movieId);
if (!movie) return this.props.history.replace("/not-found");
this.setState({ data: this.mapToViewModel(movie) });
}
mapToViewModel(movie) {
return {
_id: movie._id,
title: movie.title,
genreId: movie.genre._id,
numberInStock: movie.numberInStock,
dailyRentalRate: movie.dailyRentalRate
};
}
doSubmit = () => {
saveMovie(this.state.data);
this.props.navigate("/movies");
};
render() {
return (
<div>
<h1>Movie Form</h1>
<form onSubmit={this.handleSubmit}>
{this.renderInput("title", "Title")}
{this.renderSelect("genreId", "Genre", this.state.genres)}
{this.renderInput("numberInStock", "Number in Stock", "number")}
{this.renderInput("dailyRentalRate", "Rate")}
{this.renderButton("Save")}
</form>
</div>
);
}
}
I write a wrapper outside of the class:
const withRouter = WrappedComponent => props => {
const params = useParams();
const navigate = useNavigate();
return (
<WrappedComponent
{...props}
params={params}
navigate={navigate}
/>
);
};
Now, at the end of the file I will export it like below:
export default withRouter(MovieForm);
Insdie the withRouter, I get all the functions that I will use later inside the class:
const params = useParams();
const navigate = useNavigate();

TypeScript version
withRouter.tsx
import React from 'react';
import {
useLocation,
useNavigate,
useParams,
NavigateFunction,
Params,
Location,
} from 'react-router-dom';
export interface RouterProps {
router: {
navigate: NavigateFunction;
readonly params: Params<string>;
location: Location;
}
}
function withRouter(Component: React.ComponentType<RouterProps>) {
const ComponentWithRouterProp: React.FC = () => {
const location = useLocation();
const navigate = useNavigate();
const params = useParams();
return (
<Component
router={{ location, navigate, params }}
/>
);
};
return ComponentWithRouterProp;
}
export default withRouter;
MyComponent.tsx
import React from 'react';
import { connect } from 'react-redux';
import { RootState } from '##/redux/store';
import {
addSettings,
updateSettings,
} from '##/redux/mySlice';
import withRouter, { RouterProps } from '##/withRouter';
const mapState = (state: RootState) => ({
myStore: state.variation.myStore,
});
const mapDispatch = {
addSettings,
updateSettings,
};
type IProps = ReturnType<typeof mapState> & typeof mapDispatch & RouterProps;
class MyComponent extends React.Component<IProps> {
constructor(props: IProps) {
super(props);
}
onNavigateHome = () => {
this.props.router.navigate('/');
}
render(): React.ReactNode {
return (
<div className="test" onClick={this.onNavigateHome}>test</div>
);
}
}
export default withRouter(connect(mapState, mapDispatch)(MyComponent));

I had a similar issue, described here:
Params from React Router with class components and typescript
I created a new functional component, so I can use useParams():
import React from 'react';
import { useParams } from 'react-router';
type Props = {
children: JSX.Element
};
export const WithParams: React.FC<Props> = (props) => {
const params = useParams();
return React.cloneElement(props.children, {...props.children.props, ...params });
};
and added it to my Route.element
<Route path="/Contacts/VerifyEmailAddress/:id"
element={
<WithParams>
<VerifyEmail />
</WithParams>
}>
</Route>
and added the parameters I need to the props of my child component.
export class VerifyEmailProps {
public id?: string;
}
