Http 404 on Azure Websites for react app - node.js

Question

I have published a react app which works locally to an azure website, I checked the files on the KUDU dashboard, and I can see the files there and the index.html
However, I cant browse to the site, not even directly to the .html file.
I created this web.config, but I guess I am missing some configuration

-->
<configuration>
<system.webServer>
<!-- Visit http://blogs.msdn.com/b/windowsazure/archive/2013/11/14/introduction-to-websockets-on-windows-azure-web-sites.aspx for more information on WebSocket support -->
<webSocket enabled="false" />
<handlers>
<!-- Indicates that the server.js file is a node.js site to be handled by the iisnode module -->
<add name="iisnode" path="server.js" verb="*" modules="iisnode"/>

<!-- Do not interfere with requests for node-inspector debugging -->

You can control how Node is hosted within IIS using the following options:
* watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
* node_env: will be propagated to node as NODE_ENV environment variable
* debuggingEnabled - controls whether the built-in debugger is enabled
See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options

<!--<iisnode watchedFiles="web.config;*.js"/>-->

Answer 1

Basically the answer is to change the web.config to handle routing correctly like this:
<?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>
