package.json has various sections, scripts is one of them, which allows you to write npm script 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 script 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.

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