    javascript - React Router v4 not rendering components - Stack Overflow

    programmeradmin3浏览0评论

    Having an issue with React Router v4 rendering ponents. On initial load of the application it will render the correct ponent corresponding to the URL However, any subsequent Link clicks will not render the desired ponent.

    Libraries

    • React Router: 4.2.2
    • React: 15.6.1
    • React DOM: 15.6.1
    • -- just to mention libraries in case of impact --
      • React Redux: 5.0.6
      • Redux: 3.7.2
      • Material UI: 0.19.0

    Going to omit some imports for sake of brevity

    Site Structure

    index.jsx
  |
  App.jsx
    |
    Auth.jsx
      |
      Layout.jsx
        <Routes />

    index.jsx

    import React from 'react';
import store from './store.js';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { BrowserRouter } from 'react-router-dom';

import createBrowserHistory from 'history/createBrowserHistory';
const history = createBrowserHistory();

import App from './containers/App.jsx';

ReactDOM.render(
  <Provider store={store}>
    <MuiThemeProvider muiTheme={muiTheme}>
      <BrowserRouter>
        <App />
      </BrowserRouter>
    </MuiThemeProvider>
  </Provider>,
  document.getElementById('root')
);

    App.jsx

    import React, { Component } from 'react';
import Auth from '../ponents/Auth.jsx';

class App extends Component {
  render() {
    return <Auth />;
  }
}

    Auth.jsx

    import React from 'react';
import { Route } from 'react-router-dom';
import Layout from './Layout.jsx';

export default function Auth(props) {
  //this Has a render function to render a Loader, Error Page, or the Layout
  return <Layout />;
}

    Layout.jsx

    There's more plexity involved here with rendering out the entire application. I'm going to leave the other layout ponents mented out and just have some Links and a Switch ponent to get that working before making items more modular. 

    import React, { Component } from 'react';
import { Link, Switch, Route } from 'react-router-dom';

import Overview from './views/overview/Overview.jsx';
import Home from './views/home/Home.jsx';

export default class Layout extends Component {
  render() {
    return (
      <div className="layout">
        {/* <TopBar /> */}
        {/* <AppBar/> */}
        {/* <Drawer>
              <MainMenu/>
            </Drawer> */}

            <Link to="/">HOME</Link>
            <Link to="/overview">Overview</Link>
            <Switch>
                <Route path="/" exact ponent={Home} />
                <Route path="/overview" ponent={Overview} />
            </Switch>

        {/* <Routes /> */}
        {/* <Footer /> */}
      </div>
    );
  }
}

    Routes.jsx

    This is what I'm intending the routes ponents to look like. 

    import React from 'react';
import { Switch, Route } from 'react-router-dom';

import Home from './views/home/Home.jsx';
import Overview from './views/overview/Overview.jsx';
import Admin from './views/admin/Admin.jsx';
import NotFound from './NotFound.jsx';

export default function Routes(props) {
  return (
    <Switch>
      <Route path="/" exact ponent={Home} />
      <Route path="/overview" ponent={Overview} />
      <Route path="/admin" ponent={Admin} />
      <Route ponent={NotFound} />
    </Switch>
  );
}

    Is there something I'm missing to get ponents to render clicking Link? I'm not getting any console errors or anything telling me there's an issue. So not sure if ponents are not wrapped correctly or what may be causing the issue.

    Reset to default 15

    Looks like what was happening is that with Redux integrations was blocking updates.

    Need to:

    import {withRouter} from 'react-router-dom';

    export default withRouter(connect(mapStateToProps, mapDispatchToProps)(App))'

    Documentation

    You can also use pure: false in connect.
