React router global header

The question is already answered but I'm here to show another approach and say why I prefer that.

I also think that it's a good thing to have a Layout component

function Layout (props) {
  return (
    <div>
      <Header/>
      <div className="content">
        {props.children}
      </div>
    </div>
  );
}

But instead of render it into each route component you can render it just once as a parent for your routes.

return (
  <Router>
    <Layout>
      <Switch>
        <Route path="/about">
          <About/>
        </Route>
        <Route path="/contact">
          <Contact/>
        </Route>
        <Route path="/">
          <Home/>
        </Route>
      </Switch>
    </Layout>
  </Router>
);

This is good because in most cases you will not waste time with the layout and if you have different layouts you only need to work inside the Layout component.

I find this way useful:

import React, { Component } from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import Header from "./components/Header";
import Home from "./components/Home";
import Dashboard from "./components/Dashboard";
import Footer from "./components/Footer";
class App extends Component {
  constructor() {
    super();
    this.state = {
      stuff: stuff;
    };
  }
render() {
 let { stuff } = this.state;
 return (
  <Router> //wrapper for your router, given alias from BrowserRouter
   <div className="App">
    <Header /> //this component will always be visible because it is outside of a specific Route
    <Route exact path="/" component={Home}/>  //at the root path, show this component
    <Route path="/dashboard" component={()=><Dashboard stuff={stuff} />}/>  //at the path '/dashboard', show this other component
    <Footer /> //this is also permanently mounted
   </div>
  </Router>
 );
 }
}
export default App;

For forcefully refresh Header inside routing. use forceRefresh={true}

const Routing = () => {
        return(
            <BrowserRouter forceRefresh={true}>
            <Header/>
            <Switch>
                    <Route exact path="/" component={Home}/>
                    <Route path="/list/:id" component={ListingApi}/>
                    <Route path="/details/:id" component={HotelDetails}/>
                    <Route path="/booking/:hotel_name" component={PlaceBooking}/>
                    <Route path="/viewBooking" component={ViewBooking}/>
                    <Route exact path="/login" component={LoginComponent}/>
                    <Route  path="/signup" component={RegisterComponent}/>
            </Switch>
            <Footer/>
            </BrowserRouter>
        )
    }

From my experience it can be good to define a layout component for your page, something like...

Layout Component

render() {
    return(
       <div>
          <Header />
             { this.props.children }
             /* anything else you want to appear on every page that uses this layout */
          <Footer />
       </div>
    );
}

You then import layout into each of your page components...

Contact Page Component

render() {
    return (
        <Layout>
           <ContactComponent />
           /* put all you want on this page within the layout component */
        </Layout>
    );
}

And you can leave your routing the same, your route will render the contact page and in turn will render your header.

This way you get control of repetitive stuff that will be on multiple pages, if you need one or two slightly different pages you can just create another layout and use that.
