Node.js development for unbelievers

A comparison between python, java, and node.js as development platforms, with small node code samples (mostly on modules, and general commands)

11. What • Platform • Modules • Languages
12. Modules • Applications – Pip/Easyinstall – Jar/Maven (+osgi) – npm • Resolution – Module (npm, osgi) – Path (sys.path, classpath)
13. Modules > Resolution
14. Modules > Resolution > Module
15. Modules > Resolution > Path
16. Modules > Resolution
17. Modules > Resolution
18. Modules > Resolution > Module
19. Modules > Resolution > Path
20. What • Platform • Modules • Languages
21. Languages > Python • Python – 2.7 – 3.4
22. Languages > Java • Specific – Java – Groovy – Scala – Haskell • Existing – Jython (2.7) – Jruby – JavaScript (Nashorn)
23. Languages > Node • Specific – JavaScript – CoffeeScript – TypeScript • Existing – C++ (asm.js)
24. Demo
25. Conclusions • Node.js is awesome
26. Conclusions • Platform – module isolation – performance – independence • Module – super simple • Language – type safety – language constellations
