npm ERR! Missing script: "start"  
npm ERR! Did you mean one of these?
npm ERR!     npm star # Mark your favorite packages
npm ERR!     npm stars # View packages marked as favorites
npm ERR! To see a list of scripts, run:

Just happened to me and my package.json was correct. My fix was that I had something running on port 3000 & didn't realize it.

  1. I used the debugger on the "start" code line under "Scripts" in the package.json
  2. It told me something was already running on port 3000 then asked " Would you like to run the app on another port instead? (Y/N)
  3. I click my "Y" key - the debugger compiled and opened my app on port 3001
  4. Form I was trying to render loaded perfectly

I had the same error and I had the "start" script and everything should have worked, but it didn't. What actually helped me eventually was just saving the changes, ctrl+s. That's it, I just had to save changes and then it worked.

  • Option_1: Control inside file "package.json":
"scripts": {            
    "start": "what command is here?",                  
    },
  • Option_2: Control Terminal (folder) where you write command OR open the responding terminal for your project: right-click on the project name -> "Open in integrated Terminal"

package.json has various sections, scripts is one of them, which allows you to write npm scripts which we can run using npm run <script-name>. The error you're getting is because your start script is missing in that section.

For a node app, your package.json file should look similar to this.

{
    "name": "server",
    "version": "1.0.0",
    "description": "",
    "main": "app.js",
    "scripts": {
        "start": "node app.js",
        "test": "echo \"Error: no test specified\" && exit 1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "dependencies": {
        "body-parser": "^1.20.0",
        "cors": "^2.8.5",
        "express": "^4.17.3"
    }
}

In the above code, focus on the scripts section. The following line is missing in your package.json file.

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

Add this line and you're good to go.

You have to put what command you need npm to run when you give npm start.

enter image description here

You have to write node index.js in scripts.start in your package.json file
