Q:

node js POST mysite/uploads 404 (Not Found) when uploaded to azure but works locally

I'm working on an upload project for a small webpage and I made it all work locally, I can upload files, I can manipulate them and I can get necessary data in response. I pushed the whole thing on azure last night and now when I try to upload something I get 
POST mysite/uploads 404 (Not Found)

My file.html 
<form id="uploadForm" 
enctype="multipart/form-data" action="/uploads" method="post">
<input type="file" name="userPhoto" class="btn btn-wire" />
<input type="submit" value="Upload" name="submit" class="btn btn-primary" />
</form>

html-file.js
jQuery(document).ready(function () {

$('#uploadForm').submit(function () {
        $("#status").empty().text("File is uploading...");
        $(this).ajaxSubmit({
            error: function (xhr) {
                $("#status").text('Error: ' + xhr.status);
                //alert(JSON.stringify(xhr));
            },
            success: function (response) {
               // var test = JSON.stringify(response[1], null, 4);
               // console.log(JSON.stringify(response, null, 4));
                files = [];
                $(response).each(function (index) {
                    files.push(response[index]);
                })
                refreshFiles();
                alert("alertsuccess");
                $("#status").empty().text("File is uploaded...");                  
            }
        });
        return false;
    });
});

nodeapp.js
app.use(multer({

dest: "./uploads",
onFileUploadStart: function (file) {
    console.log(file.originalname + ' is starting ...');  
},
onFileUploadComplete: function (file) {
    values = JSON.stringify(file);
    console.log(values);
    test.push({ "url": file.path, "filename": file.name, "fileType": file.extension });

}
}));
 app.post('/uploads'), function (req, res) {
        upload(req, res, function (err) {
            if (err) {
                return res.end("Error uploading the file!");
            }
            else {

                //res.json({ "test": "test123" });
                res.json(test)
                // res.write(JSON.stringify(test, null, 4));

                res.end();
                test = [];
            }
        })
    })

There's quite a bit more code but for the sake of simplicity and my general suspiciousness on this particular part of project I posted only these snippets.

How do you deployment to Azure Web Apps? As Node.js applications running on Azure Web Apps are hosted on IIS via IISNode. So there is a web.config file required  to config your application on IIS.
You may check this file in your root directory of your site, whether it is in the correct configurations.
Here is a sample of a web.config:
<configuration>
     <system.webServer>
          <handlers>
               <!-- indicates that the app.js file is a node.js application to be handled by the iisnode module -->
               <add name="iisnode" path="server.js" verb="*" modules="iisnode"/>
          </handlers>
          <rewrite>
               <rules>

                    <!-- Don't interfere with requests for node-inspector debugging -->
                    <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">                    
                        <match url="^server.js\/debug[\/]?" />
                    </rule>

                    <!-- First we consider whether the incoming URL matches a physical file in the /public folder -->
                    <rule name="StaticContent">
                         <action type="Rewrite" url="public{REQUEST_URI}"/>
                    </rule>

                    <!-- All other URLs are mapped to the Node.js application entry point -->
                    <rule name="DynamicContent">
                         <conditions>
                              <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
                         </conditions>
                         <action type="Rewrite" url="server.js"/>
                    </rule>

               </rules>
          </rewrite>
          <!-- You can control how Node is hosted within IIS using the following options -->
        <!--<iisnode watchedFiles="*.js;node_modules\*;routes\*.js;views\*.jade"/>-->
     </system.webServer>
</configuration>
