react router dom useeffect location code example

Example 1: usematch react router

import React from 'react'
import ReactDOM from 'react-dom'
import { useParams } from 'react-router-dom'

function BlogPost() {
  // We can call useParams() here to get the params,
  // or in any child element as well!
  let { slug } = useParams()
  // ...
}

ReactDOM.render(
  <Router>
    <div>
      <Switch>
        {/* No weird props here, just use
            regular `children` elements! */}
        <Route path="/posts/:slug">
          <BlogPost />
        </Route>
      </Switch>
    </div>
  </Router>,
  document.getElementById('root')
)

Example 2: react router dom current path hook

import { useLocation } from 'react-router-dom'

// Location is, for example: http://localhost:3000/users/new

// Care! MyComponent must be inside Router to work
const MyComponent = () => {
	const location = useLocation()
    
    // location.pathname is '/users/new'
    return <span>Path is: {location.pathname}</span>
}

export default MyComponent
