Creating Node Package

This is a simple exmaple of creating node pakcage.

To create a node package
  • Create a folder say 'hello-world-node-package'
  • Under this filder create package.json - you can create package.json manually or run 'npm init' to auto generate the file.
  • My package.json looks something like this
    {
      "name": "hello-world-node-package",
      "version": "1.0.1",
      "description": "Creating Node Package. This is a simple exmaple of creating node pakcage.",
      "main": "index.js",
      "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
      },
      "keywords": [],
      "author": "KK",
      "license": "ISC",
      "repository": {
        "type": "git",
        "url": "https://github.com/webrolls/hello-world-node-package.git"
      },
      "bugs": {
        "url": "https://github.com/webrolls/hello-world-node-package/issues"
      },
      "homepage": "https://github.com/webrolls/hello-world-node-package#readme"
    }
    
  • In the same folder create index.js and add all your package logic in this file.
  • For example for 'hello-world-node-package' package I have following JavaScript
    function helloWorld() {
      console.log('Hello World!');
    }
    function doSomethingAwesome() {
      console.log('Doing something awesome...');  
    }
    function doSomethingElse() {
      console.log('Now something else...'); 
    }
    module.exports = {
      helloWorld: helloWorld,
      doSomethingAwesome: doSomethingAwesome,
      doSomethingElse: doSomethingElse
    }
    
  • Now when you are done with the package implimentation its a time to publish the package...
  • To publish the package run
    npm adduser
  • It will prompt to ask your your name, password and your email id, provide the information and hit enter...
  • Verify your email address from npm site
  • Once the email id is confirmed, you can now publish the package using using ...
    npm publish
  • If everything went as expected your package is added to the NPM
  • You can confirm that the package is added successfuly by visiting https://www.npmjs.com/~your-user-name
  • Thats all, we are done adding the package and its ready to used and download.

To verify if out package is working fine, you can install the package using

npm install --save

create a file 'index.js' and add

var test = require('hello-world-node-package');

test.helloWorld();
test.doSomethingAwesome();
test.doSomethingElse();

and bingo! on the console we will see the following output

Hello World!
Doing something awesome...
Now something else...

checkout https://www.npmjs.com/~webrolls for above created node package.
