Node.js 'npm start' command fails with error

I’m having trouble with my Node.js project. When I run ‘npm start’ in the terminal, it throws an error. Here’s a snippet of the error log:

4 verbose stack Error: missing script: start
4 verbose stack     at run (C:\Users\DevUser\AppData\Roaming\npm\node_modules\npm\lib\run-script.js:151:19)
4 verbose stack     at C:\Users\DevUser\AppData\Roaming\npm\node_modules\npm\lib\run-script.js:61:5
...
10 error missing script: start
11 verbose exit [ 1, true ]

It looks like the ‘start’ script is missing. I’ve checked my package.json file, but I’m not sure what I’m doing wrong. Any ideas on how to fix this? I’m using npm version 5.4.2 and Node.js version 6.11.3 on Windows if that helps.

I’ve encountered this issue before, and it’s usually related to the package.json file. Based on the error message, it seems your package.json is missing the ‘start’ script in the ‘scripts’ section. Here’s what you can do:

Open your package.json file and look for the ‘scripts’ object. If it’s not there, add one. Then, define a ‘start’ script that specifies how to run your application. For example:

"scripts": {
  "start": "node app.js"
}

Replace ‘app.js’ with the actual entry point of your application. If you’re using a framework like Express, it might be ‘server.js’ or ‘index.js’.

After making this change, save the file and try running ‘npm start’ again. This should resolve the ‘missing script: start’ error. If you’re still having issues, double-check that your package.json is valid JSON and that you’ve saved the changes correctly.

This error typically occurs when the ‘start’ script isn’t defined in your package.json file. To resolve it, you’ll need to add the script manually. Open your package.json and locate the ‘scripts’ section. If it doesn’t exist, create it. Then, add a ‘start’ script that points to your main application file. For instance:

“scripts”: {
“start”: “node index.js”
}

Replace ‘index.js’ with your actual entry point file. Save the changes and try ‘npm start’ again. If you’re unsure which file to use, check your project structure or consult your project’s documentation. This should fix the ‘missing script’ error and allow you to start your application properly.
