React-router

Introduction

This page is about routering with React.

Setup

We need to install the pacakge

npm i react-router-dom

Change Index.js

...
import { BrowserRouter } from 'react-router-dom';
...
ReactDOM.render(
  <React.StrictMode>
    <BrowserRouter>
      <App />
    </BrowserRouter>
  </React.StrictMode>,
  document.getElementById('root')
);

Transitions

You need to provide a class prefix in this case trans.

import {TransitionGroup, CSSTransition} from 'react-transition-group'

<TransactionGroup>
  <CSSTransition key={location.key} classNames={'trans'} timeout={1000}>
    <Switch location={location}>
     <Route path={`${match.url}`} component={LoremNumber} exact/>
     <Route path={`${match.url}/:id`} component={LoremNumber} exact/>
    </Switch>
</TransactionGroup>

And the CSS

.trans-enter {
   opacity: 0;
   z-index: 1;
}

.trans-exit {
   display: none
}

.trans-enter.trans-enter-active {
   opacity: 1;
   transition: opacity 1000ms ease-in;
}
