import React from 'react';
import {BrowserRouter, Route, Switch, Link, NavLink} from 'react-router-dom';
import landingPage from '../components/landingPage';
import editPage from '../components/editPage';
import createPage from '../components/createPage';
import helpPage from '../components/helpPage';
import notFoundPage from '../components/notFoundPage';
import Header from '../components/header';


const AppRouter = () => (
    <BrowserRouter>
        <div>
            <Header/>
            <Switch>
                <Route exact={true} path="/" component={landingPage}/>
                <Route path="/create" component={createPage}/>
                <Route exact={false} path="/edit/:id" component={editPage}/>
                <Route path="/help" component={helpPage}/>
                <Route component={notFoundPage}/>
            </Switch>

export default AppRouter;

import React from 'react';

const editPage = (props) => {
    console.log(props)
    return (
    <div>Edit Page</div>
    );
}
export default editPage;
