    Hi @Tejas Lade

    I understand the issues you are having, have you considered using Azure Static Web Apps ( See the quick start for a tutorial that will guide you through setting up a react app.

    Hi @Tejas Lade , I want to expand on Claudia's answer- The issue you’re experiencing is a common one with single-page applications (SPAs) like your React app, where the routing is handled on the client-side. When you refresh the page, the server tries to find a resource matching the route, which doesn’t exist, hence the 404 error Here’s how you can fix this issue:

    1. You need to add a fallback route in your server configuration that will serve your index.html file for all routes This allows the React router to handle the routing on the client-side. If you’re using Azure Static Web Apps, you can add this fallback route in the staticwebapp.config.json file.
    2. If you’re using Azure App Service, you can add a web.config file at the root of your project that rewrites all routes to index.html

    Here’s an example of what the web.config file could look like:

                    <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" />
                        <action type="Rewrite" url="index.html" />

    This configuration will rewrite all requests to index.html, allowing the React router to handle the routing. Best, Grace
