React JS App Routing Issue Only After Deploying to Azure Web App

Question

I have a React JS app, with React Router.During development, npm start, I get no issues. I visit the following location as usual.

http://localhost:3000

and due to the routing code, it becomes

http://localhost:3000/index

and the app loads just fine. At this point,

I hit reload, the app continues to run fine.
I manual link or load 'http://localhost:3000/index', the app runs fine.

Then, later, I do an npm build, go inside this build folder, and do an npm start, again, the same thing. the app runs just fine. I reload, it runs fine. Nothing to complain so far.

Problem Portion.

I then decided to deploy the app to an azure web app. The app runs fine. I go to this site.

https://randomstuffreactjsappsept24.azurewebsites.net

and due, to routing code, it becomes

https://randomstuffreactjsappsept24.azurewebsites.net/index

And, the website loads.

At this point, if I hit reload (problem!!), it will try to reload,

https://randomstuffreactjsappsept24.azurewebsites.net/index

I get the following error.

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Now, at this point, if I remove the '/index' and load the original url,

https://randomstuffreactjsappsept24.azurewebsites.net

The site loads just fine, no problem. Note, you can see it for yourself. this is a live site. (but of course, due to routing code, it becomes)

https://randomstuffreactjsappsept24.azurewebsites.net/index

Now, as long as I dont reload the website, the website continues to run. Why is this happening?

Here is the code for the main index.js page from the project.

ReactDOM.render(
  <BrowserRouter>
    <Switch>
      <Route path="/index" render={(props) => <Index {...props} />} />
      <Redirect to="/index" />
    </Switch>
  </BrowserRouter>,
  document.getElementById("root")
);

The full app is available here - https://github.com/Jay-study-nildana/RandomStuffReactJSApp

Update 2

I decided to try another react app, created by another source entirely. Once again, same issue, and I have a live site to show.

I visit, https://auth0tokenreactjsappprivatesept25.azurewebsites.net/external-api, from within the web app, it works fine. If i were to reload at this point, it will say "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."
I visit, http://localhost:3000/external-api, from within the app, it works fine. AND, If I were to reload, it loads just fine.

So, its definitely "only" happening after deployment.

According to: https://github.com/react-boilerplate/react-boilerplate/issues/1612 You would have to place the: Simply place the following file called web.config under your wwwroot folder:

<?xml version="1.0"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="React Routes" stopProcessing="true"> <match url=".*" /> <conditions logicalGrouping="MatchAll"> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> <add input="{REQUEST_URI}" pattern="^/(api)" negate="true" /> </conditions> <action type="Rewrite" url="/" /> </rule> </rules> </rewrite> </system.webServer> </configuration>

Add the web.config file to the azure directory

I came accross this issue yesterday after using a custom build in my azure web app deployment (skipped it using skip_app_build = false and build it in a previous job).

My error was that my staticwebapp.config.json file was not located in the public folder -> it was not deployed correctly. after inserting any route a 404 was thrown by azure.

Just move the staticwebapp.config.json into the public folder and you are good to go.

I had the same problem. Our Azure App Servive was running PHP and Apache, so we used a .htaccess file like this one suggested in the deployment docs of Create React App. https://create-react-app.dev/docs/deployment#serving-apps-with-client-side-routing

    Options -MultiViews
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.html [QSA,L]

Add the .htaccess to the public folder and this stops your refresh issue these types of Aapp Services.
