This document compares three Node.js frameworks: Express, Koa, and Hapi, highlighting their GitHub stars, contributors, and weekly downloads. It includes sample code for setting up servers and handling routes in each framework, along with testing using Dredd. Additionally, it mentions hosting the project on GitHub and suggestions for improvements.

- 15. Github repository of project: https://github.com/abtris/nodeschool-hk-2015-05-23 Ideas how project improve: • you can fork and contribute • you can try add 404, 500 pages • you can try persistent layer using Redis
