4.Now create an index.js file in this folder, your folder should look like this
firstnpmpackage
  • index.js
  • package.json
5.write some code in index.js
#!/usr/bin/env node function randomNoGenerator(min, max) { if(typeof(max) !== 'number' && typeof(min) !== 'number') { min = 0; max = 1; } console.log(Math.random() * (max-min)) + min; } randomNoGenerator(5,10);
6.Now let's modify our package.json a bit to make it work using cli.
"bin":{ "demoproject" : "index.js" },
just add this thing in your package.jsondemoproject is the command you will use to execute your package through cli.index.js is the file that will be first triggered.

7.We are all ready to go ,but wait wait you will really want to test your package locally before publishing it.
Let's do it first :run
sudo npm install -g ./
Our package is installed in our local machine now,Let run it type this in your cli and see the result.

9.Now we are ready to go ..open terminal in your root directory..
and Run :
