Start script missing error when running npm start

Question

I'm receiving this error when trying to debug my node application using the npm start command.

Error:

npm ERR! Windows_NT 6.3.9600 npm ERR! argv "C:\\Program Files\\nodejs\\\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "start" npm ERR! node v0.12.7 npm ERR! npm  v2.11.3  npm ERR! missing script: start npm ERR! npm ERR!

From the debug file:

It looks like you might not have defined a start script in your package.json file or your project does not contain a server.js file.

If there is a server.js file in the root of your package, then npm will default the start command to node server.js.

https://docs.npmjs.com/misc/scripts#default-values

You could either change the name of your application script to server.js or add the following to your package.json

"scripts": {     "start": "node your-script.js" } 

Or ... you could just run node your-script.js directly
