Accepted answer

You can't use hooks inside Catalog component because it is a class component. So you have two ways to resolve your issue:

  1. Rewrite your component from class to functional.
  2. Do not use useRouteMatch inside Catalog component. If you need to get match data inside a component, you need to use withRouter high-order component.

So if you select second way, you will need to wrap your Catalog component in withRouter:

export default withRouter(Catalog);

Change one row in render function from:

let { path, url } = useRouteMatch();

To:

const { path, url } = this.props.match;

And do not forget to change the import of your Catalog component, because now your component exports as default.

Try adding useParams when you export like:

export default (props) => <NewComponent {...props} {...useParams()} />

Full example:

<Route exact path='/event/:id' element={<NewComponent />}/>

inport {useParams } from "react-router-dom";

class NewComponent extends React.Component {
  render() {
    return <div>{this.props.id}</div>
  }
}

// Bind url parameters here
export default (props) => <NewComponent {...useParams()} {...props} />

As I had the same issue when setting up my React Router with Typescript, I will detail a little bit more Andrii answer in 4 steps:

1 - npm/yarn packages

yarn add react-router-dom --save
yarn add @types/react-router-dom --save-dev

or

npm install react-router-dom --save
npm install @types/react-router-dom --save-dev

2 - index.tsx


1) When importing your higher order component (App in the present case), do not use curly brackets as App will be exported as default;

2) BrowserRouter needs to be in a upper level rather the class that will be exported as "default withRouter(Class)", in order to prevent the following error:

"You should not use Route or withRouter() outside a Router"

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import * as serviceWorker from './serviceWorker';
import App from './app';

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

serviceWorker.unregister();

3 - app.tsx


1) Import from react-router-dom, withRouter & RouteComponentProps (or your own PropType definition);

2) Extend React.Component and use the RouteComponentProps interface;

3) Pass the props to components you want to share routing data;

4) Export the higher order class as default withRouter.

import React, { ReactElement } from 'react';
import { Switch, Route, withRouter, RouteComponentProps } from 'react-router-dom';
import { ExpensesPage } from './pages/expenses/expenses.page';
import { HomePage } from './pages/home/home.page';
import { HeaderComponent } from './components/header/header.component';
import './app.scss';

class App extends React.Component<RouteComponentProps> {
  public render(): ReactElement {
    return (
      <div className='playground'>
        <HeaderComponent {...this.props} />
        <div className="playground-content">
          <Switch>
            <Route exact path='/' component={HomePage} {...this.props} />
            <Route exact path='/expenses' component={ExpensesPage} {...this.props} />
          </Switch>
        </div>
      </div>
    );
  }
}

export default withRouter(App);

4 - header.component


Through your RouteComponentProps extending your class, you can access normally the routing props as history, location and match as bellow:

import React, { ReactElement } from 'react';
import { RouteComponentProps } from 'react-router-dom';
import './header.component.scss';

export class HeaderComponent extends React.Component<RouteComponentProps> {
  public render(): ReactElement {
    const { location } = this.props;
    console.log(location.pathname);

    return (
      <header className="header">
        {/* ... */}
      </header >
    );
  }
}

Hope it helps because I had a bit of challenge to make this works in a simple environment with webpack and no redux. Last time working properly with the following versions:

{
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-router-dom": "^5.1.2",
    "sass-loader": "^8.0.2",
    "style-loader": "^1.1.3",
    "typescript": "^3.8.2",
    "webpack": "^4.41.6",
    "webpack-dev-server": "^3.10.3",
},
{
    "@types/react-router-dom": "^5.1.3",
    "webpack-cli": "^3.3.11"
}
