How to use the useParams hook in React router

In this tutorial, we are going to learn about how to use the useParams() hook in react router.

If you are new to hooks then check out my react hooks introduction tutorial.

useParams() hook

The useParams() hook helps us to access the URL parameters from a current route.

Example:

Consider, we have a route like this in our react app.

<Route path="/users/:id" component={Users} />

Now, we can access the :id param value inside a Users component by using the useParams() hook.

import React from "react";
import { useParams } from "react-router-dom";
export default function Users() {
  const { id } = useParams();
  return (
    <div>
      <h1>User id is {id}</h1>    </div>
  );
}

In the above code, we first imported the useParams() hook from the react-router-dom package.

Inside the Users function, we invoked a useParams() hook that returns an object with key/value pairs where the key is id and value is whatever we passed after /users/ route in the browser.
