Sometimes, we want to disable a Link if it’s active in React Router.

In this article, we’ll look at how to disable a Link if it’s active in React Router.

How to disable a Link if it’s active in React Router?

To disable a Link if it’s active in React Router, we set the to path of the Link‘s pointer-events CSS property to none.

For instance, we write

<Link to="/bar" className="disabled-link">
  Bar
</Link>

to add the disabled-link class to the Link.

And we set the disabled-link class’ CSS by writing

.disabled-link {
  pointer-events: none;
}

to disable the mouse pointer we usually see over a link with pointer-events with none.

Conclusion

To disable a Link if it’s active in React Router, we set the to path of the Link‘s pointer-events CSS property to none.

Sometimes, we want to use React Router with Electron.

In this article, we’ll look at how to use React Router with Electron.

How to use React Router with Electron?

To use React Router with Electron, we can use HashRouter.

For instance, we write

import { HashRouter, Route } from "react-router-dom";

to import HashRouter.

Then we write

<HashRouter>
  <div>
    <Route path="/" exact component={Home} />
    <Route path="/firstPage" component={FirstPage} />
    <Route path="/secondPage" component={SecondPage} />
  </div>
</HashRouter>

to wrap HashRouter around our Routes to render them.

HashRouter works because Electron runs our React app in a file-based environment.

Conclusion

To use React Router with Electron, we can use HashRouter.

Sometimes, we want to set up Google Analytics for React Router.

In this article, we’ll look at how to set up Google Analytics for React Router.

How to set up Google Analytics for React Router?

To set up Google Analytics for React Router, we can create our own hook to submit data to Google Analytics.

For instance, we write

import { useEffect } from "react";
import { useLocation } from "react-router-dom";
import ReactGA from "react-ga";

const usePageTracking = () => {
  const location = useLocation();

  useEffect(() => {
    ReactGA.initialize("UA-000000000-0");
    ReactGA.pageview(location.pathname + location.search);
  }, [location]);
};

export default usePageTracking;

to create the usePageTracking hook that calls the useLocation hook to get the current location.

And then we listen to location with the useEffect hook and calls ReactGA.initialize to initialize Google Analytics.

And then we call ReactGA.pageview with the full URL which we get with location.pathname + location.search.

Conclusion

To set up Google Analytics for React Router, we can create our own hook to submit data to Google Analytics.

Sometimes, we want to use React Router without changing the URL.

In this article, we’ll look at how to use React Router without changing the URL.

How to use React Router without changing the URL?

To use React Router without changing the URL, we can use the MemoryRouter component.

For instance, we write

import { MemoryRouter } from 'react-router'

<MemoryRouter>
  <App/>
</MemoryRouter>

to import the MemoryRouter component and then wrap it around App to let us navigate with React Router without changing URLs.

Conclusion

To use React Router without changing the URL, we can use the MemoryRouter component.

Sometimes, we want to fix React Router v4 routes not working.

In this article, we’ll look at how to fix React Router v4 routes not working.

How to fix React Router v4 routes not working?

To fix React Router v4 routes not working, we may need the exact prop to make React Router search for an exact path match.

For instance, we write

<Route exact path="/" component={Home} />;

to add the exact prop so that going to / will render the Home component.

Conclusion

To fix React Router v4 routes not working, we may need the exact prop to make React Router search for an exact path match.
