Let’s Build Some Shit Making your first NPM package. @rdegges

Hey, I’m Randall Developer Evangelist, Stormpath Open Source Dude <333 The Codez

(My Goal for You) I just shipped my first Node package to NPM!

What’s a Package, Anyway? $ npm install ipify // test.js var ipify = require('ipify'); ipify(function(err, ip) { console.log('My public IP address is:', ip); });

How do Packages Work? { "name": "package", "version": "1.0.0", "description": "A simple package.", "bin": "./index.js", "author": "Randall Degges", "license": "ISC" }

What do Packages Look Like?

Let’s Make a Package!

What We’ll Make https://thepiratebay.la/top/207

github.com/rdegges/tpb-top100

The Codez #!/usr/bin/env node 'use strict'; var cheerio = require('cheerio'); var request = require('request'); var TPB_URL = 'https://thepiratebay.la/top/207'; request(TPB_URL, function(err, resp, body) { if (err || resp.statusCode !== 200) { throw new Error("Couldn't reach thepiratebay... It might be down :("); } console.log('Top 100 Movies from The Pirate Bay'); console.log('----------------------------------\n'); var $ = cheerio.load(body); $('#content .detName a').each(function(index, element) { console.log(index, $(this).text()); }); }); index.js

MORE INFOZ! $('#content .detName a') $(this).text()
