5. Run: nssm set Apollo AppDirectory "D:\directory\apps\apollo\src"

6. Run: nssm set Apollo AppParameters "index.js"

7. Run: nssm start Apollo

Method 2

1. Create a file in the root of the Apollo application folder called ApolloService.js

2. Paste the following into the file (make sure to update the script location)

   //run Apollo as a windows service
   var Service = require('node-windows').Service;
   
   // Create Apollo Service object
   var svc = new Service({
   name:'Apollo',
   description: 'Apollo app run as a service',
   script: 'D:\\directory\\path\\onsite\\src\\index.js'
   });
   
   // Listen for the "install" event, which indicates the
   // process is available as a service.
   svc.on('install',function(){
   svc.start();
   }); svc.install();

3. Using CMD as Administrator run the following commands:

   npm install -g node-windows
   npm link node-windows
   npm install node-windows
   node ApolloService.js
