Npm

Node package manager

from egghead series https://github.com/kentcdodds/starwars-names.git

versioning

1.0.0 is typical with the major release number getting changed any time the api changes. Adding features would change the second digit and bug fixes would change the last digit.

process

modify package.json to new version, say 1.1.0

git add . -A
git commit -m 'about new version'
git push
git tag 1.1.0
git push --tags
npm publish

beta process

from current version, say 1.3.0 to add a beta feature bump the version to 1.4.0-beta.0

modify package.json to new version, say 1.4.0-beta.0

git add . -A
git commit -m 'about new beta version'
git push
git tag 1.4.0-beta.0
git push --tags
npm publish --tag beta

testing

npm install mocha chai --save-dev
  same as
npm i -D mocha chai

create a test file src/index.test.js

 var expect = require('chai').expect;
 var starWars = require('./index');
 describe('starwars-names', function() {
   describe('all', function() {
     it('should be an array of strings', function() {
       expect(starWars.all).to.satisfy(isArrayOfStrings);
       function isArrayOfStrings(array) {
         return array.every(function(item) {
           return typeof item === 'string';
         });
       }
     });
     it('should contain `Luke Skywalker`', function() {
       expect(starWars.all).to.include('Luke Skywalker');
     });
   });
   describe('random', function() {
     it('should return a random item from the starWars.all', function() {
       var randomItem = starWars.random();
       expect(starWars.all).to.include(randomItem);
     });
   });
 });

change package.json to run tests (automatically on update -w)

 "scripts": {
   "test": "mocha src/index.test.js -w"
 },

 npm test
