In this tutorial, we are going to learn about how to fix the start script missing error after running an npm start command in the Node app.,To fix this error, we need to add a start script with the entry point to the package.json file.,When we use a npm start command without defining it inside the package.json file scripts object we will see the following error in our terminal.

➜
npm start

npm ERR!missing script: start

npm ERR!A complete log of this run can be found in:

This error also happens if you added a second "script" key in the package.json file. If you just leave one "script" key in the package.json the error disappears.,Take a look at your client/package.json. You have to have these scripts,add this code snippet in your package.json, depending on your own configuration.

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"
}

You may get the missing script: start message if you recently updated to the newest version and tried to run npm start on your terminal. Or you may be running a command such as node Filename.js to run your file while not having a script for start. There could be other contributing factors.,If you type npm start and get the npm err! missing script: start error, there must be a missing line in the script object located in your package.json file. The error also tells us that the missing content is in regards to the start command. ,Whatever the case, you can follow the steps below to learn how to run npm start without incurring an error message.
