TL;DR: In this short tutorial I’ll show you how I built my own testable (Jasmine) npm module which I then published to npm repository.\u00a0The npm module is here<\/a>, and the GitHub repository\u00a0is here<\/a>.<\/p>\n

First, if you haven’t already, set some author info in your terminal:<\/p>\n

npm set init.author.name \"Nikola Bre\u017enjak\"\r\nnpm set init.author.email \"nikola.breznjak@gmail.com\"\r\nnpm set init.author.url \u201chttp:\/\/www.nikola-breznjak.com\"<\/pre>\n
Then, create a new GitHub repository, clone it to your disk and then run\u00a0npm init<\/strong>.\u00a0Create a index.js<\/strong> file and copy\/paste the following code:<\/p>\n
module.exports = function(){\r\n    return 42;\r\n}<\/pre>\n
Next, install Jasmine by doing:<\/p>\n
npm install jasmine-node -g<\/pre>\n
To test your module,\u00a0create a folder spec<\/strong>, and a file TheAnswerToLifeTheUniverseAndEverything.spec.js<\/strong>\u00a0inside it with the following content:<\/p>\n
var TheAnswerToLifeTheUniverseAndEverything = require('..\/index.js');\r\n\r\ndescribe(\"TheAnswerToLifeTheUniverseAndEverything Suite\", function() {\r\n it(\"should return a value of 42\", function(done) {\r\n var value = TheAnswerToLifeTheUniverseAndEverything();\r\n expect(value).toEqual(42);\r\n done();\r\n });\r\n});<\/pre>\n
In order to test\u00a0<\/strong>your module, run jasmine-node spec\/<\/strong> as shown on the image below:<\/p>\n
\"jasmineTest\"<\/a><\/p>\n
In order to publish your npm module you first have to execute the\u00a0npm adduser\u00a0<\/strong>command and answer few of the questions, and after that you just have to execute\u00a0npm publish<\/strong>\u00a0and you’ll have your npm module listed on npmjs.com:<\/p>\n
\"theAnswerToLifeNPMmodule\"<\/a><\/p>\n
Now you can use npm install\u00a0theanswertolifetheuniverseandeverything\u00a0<\/strong>to install the module.<\/p>\n
If you’re testing this your self and you get an error like “Error: forbidden New packages must have all-lowercase names: TheAnswerToLifeTheUniverseAndEverything” then that means what it says – you must use only lowercase letters when naming your modules.<\/p>\n","protected":false},"excerpt":{"rendered":"
