How do I add a custom script to my package json file that runs a javascript file

Question

I want to be able to execute the command script1 in a project directory that will run node script1.js.

script1.js is a file in the same directory. The command needs to be specific to the project directory, meaning that if I send someone else the project folder, they will be able to run the same command.

So far I've tried adding:

"scripts": {
    "script1": "node script1.js"
}

to my package.json file but when I try running script1 I get the following output:

zsh: command not found: script1

Does anyone know the steps necessary to add the script mentioned above to the project folder?

Hello @kartik,

I have created the following, and it's working on my system. Please try this:

package.json:

{
  "name": "test app",
  "version": "1.0.0",
  "scripts": {
    "start": "node script1.js"   
  }
}

script1.js:

console.log('testing')

From your command line run the following command:

npm start

Hope it helps!!

Hello @P. Muthukumar,

Try this:

Steps are below:

1. In package.json add:

   "bin":{
       "script1": "bin/script1.js" 
   }

2. Create a bin folder in the project directory and add file runScript1.js with the code:

   #! /usr/bin/env node
   var shell = require("shelljs");
   shell.exec("node step1script.js");

3. Run npm install shelljs in terminal

4. Run npm link in terminal

5. From terminal you can now run script1 which will run node script1.js

Answer 2

Try with this, Apart from predefined command like (Start, etc..) if you trying to add any custom command so you hav to must append "run" keyword
npm run script1

Answer 3
