How to solve the npm ERR! Missing script: start

Learn, how to solve the npm ERR! missing script: “start” error in your JavaScript projects.

This error occurs due to one of the following reasons:

  1. Using the start script without defining it inside the scripts object in your package.json file.

  2. Running the npm run start command in a different directory.

  3. Not initialized a package.json file in your project directory and trying to use npm start.

Run npm start
npm ERR! Missing script: "start"
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

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

To solve the npm ERR! Missing script:“start” error, add the start script to your package.json file and open the terminal in your root project directory before running the npm run start command.

Here is an example:

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

Here, I added a app.js. So, it runs the server from the app.js file in your case it will be some other.

If you don’t have package.json file in your project directory, then you can initialize it by running the npm init -y command.

npm init -y

Now, add the start script to the package.json file.

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

If you already have a start script in your package.json file, make sure you are in the root directory and try to run the npm start command.
