I need to know if my user is connected or not. For that I want to read the cookies that I set in the server side with express-session :

```js
app.use(session({
    secret: &#39;crypted key&#39;,
    resave: false,
    saveUninitialized: true,
    cookie: { secure: false } // Put true if https
}))
```

```js
app.post(&#39;/connect_user&#39;, (req, res) =&gt; {
    req.session.cookie.username = req.body.username
    findUserData(&#39;username&#39;, req.body.username, req, (userData) =&gt; {
        req.session.cookie.id = userData.id
        req.session.cookie.username = userData.username
        res.redirect(&#39;/profil&#39;)
    })
})
```

I tried to use `react-cookie` but it doesn&#39;t work even though I copy-pasted the npm `react-cookie` docs example:

```jsx
import React from &#39;react&#39;;
import Landing from &#39;./Landing&#39;;
import Home from &#39;./Home&#39;;
import Profil from &#39;./Profil&#39;;
import { BrowserRouter as Router, Route } from &#39;react-router-dom&#39;;
import { instanceOf } from &#39;prop-types&#39;;
import { Cookies } from &#39;react-cookie&#39;;

class App extends React.Component {
    static propTypes = {
        cookies: instanceOf(Cookies).isRequired
      };
     
      constructor(props) {
        super(props);
     
        const { cookies } = props;
        this.state = {
          username: cookies.get(&#39;username&#39;)
        };
      }
    render() {
        console.log(this.state.name) 
        let homePage = (!this.state.username) ? &lt;Landing/&gt; : &lt;Home/&gt;
        return (
            &lt;Router&gt;
                &lt;div&gt;
                    &lt;Route exact path=&#39;/&#39; component={homePage}&gt;&lt;/Route&gt;
                    &lt;Route path=&#39;/profil&#39; component={Profil}&gt;&lt;/Route&gt;
                &lt;/div&gt;
            &lt;/Router&gt;
        )
    }
}

export default App;
```

It&#39;s weird because `document.cookie` renders the correct result, but I don&#39;t know how handle it:

```
PHPSESSID=0nv9ic8h7pv2b63lu4v7eg3mop; user_id=21; username=Ugo; SL_G_WPT_TO=fr; SL_GWPT_Show_Hide_tmp=undefined; SL_wptGlobTipTmp=undefined
```
