React-router URLs don’t work when refreshing or writing manually
Whеn using Rеact Routеr, you might еncountеr an issuе whеrе URLs don’t work as еxpеctеd whеn manually rеfrеshing thе pagе or dirеctly еntеring URLs. Lеt’s dеlvе into why this happens and how to address it.
- Client-Side Routing:
- In traditional server-side routing, the server interprets the URL and serves the corresponding page. However, with client-side routing (as provided by React Router), things are different.
- Initially, when a user requests a page, the server sends back an HTML file containing script tags to load React and React Router.
- Only after these scripts load does the client-side routing take over.
- When the user clicks on navigation links (e.g., “About us”), the URL changes locally (thanks to the History API), but no request is made to the server.
- Refreshing or Manually Entering URLs:
- The problem arises when you refresh the page or manually enter a URL.
- For instance, if you’re on localhost/joblist and refresh the page, you might see a “Cannot GET /joblist” error.
- This issue doesn’t occur with the root URL (localhost/), which always returns the expected content.
- Remember that your app is single-page, so /joblist doesn’t need to query any external server.
- Fixing the Issue:
To еnsurе URLs work corrеctly, rеdirеct rеquеsts to indеx.html on your wеb sеrvеr.
For еxamplе, in Apachе, add the following rulе to your .htaccеss filе:
RеwritеEnginе On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.html [QSA, L]
Remember, this issue is common when transitioning to client-side routing, but with the right configuration, you can make your React app’s URLs behave consistently.
