How to serve NodeJS application from IIS/Windows Server Edition OS without using iisnode?

Issue

So, I’ve written a NodeJS application on Windows having Server Edition OS, My application basically communicates with other Softwares installed in the same system by executing some commands using NodeJS child process.

Everything is working fine on localhost, as my server has a static IP, I want to serve the application to public. How can I do this without using iisnode?

I tried using iisnode, but I am falling into issues since then, I am able to server my site, but due to some permission issues on C drive, the cmd command gives Access Denied error.

Solution

Option 1:

1. Run your Node.js app at a local binding such as http://localhost:8080 Reference
2. Set up IIS as reverse proxy Reference

iisnode provides better control on application pool integration and so on, but since it is a dead project you definitely shouldn’t use it any more.

Option 2:

Use HttpPlatformHandler to launch your Node.js app,

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" />
    </handlers>
    <httpPlatform stdoutLogEnabled="true" stdoutLogFile=".\node.log" startupTimeLimit="20" processPath="C:\Program Files\nodejs\node.exe" arguments=".\app.js">
            <environmentVariables>
                <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
                <environmentVariable name="NODE_ENV" value="Production" />
            </environmentVariables>
        </httpPlatform>
  </system.webServer>
</configuration>

Reference

Note that due to your Node.js installation, C:\Program Files\nodejs\node.exe might be a mapped path. You have to use the actual path instead, such as C:\Users\<user name>\AppData\Roaming\nvm\v16.13.2\node.exe.

Note that you also need to give IIS_IUSRS enough permissions to access node.exe.
