Overview
The following diagram is an overview of our stack:
Note: To edit/improve this diagram: https://github.com/dwyl/technology-stack/issues/1
We have produced a complete beginners guide for each of the components in our stack. (see below)

Dependencies (projects built by people we trust)
- Node.js - the most popular JavaScript runtime for easily building fast, scalable network applications. Lightweight and efficient, perfect for data-intensive real-time apps. http://nodejs.org/
- Hapi.js - A rich web framework for building applications and services. https://github.com/dwyl/learn-hapi
- Socket.io - a JavaScript library for realtime web applications. It enables realtime, bi-directional communication between web clients and server. Socket.io lets us send data to/from everyone connected to our app(s) without having to refresh the web page. http://socket.io/
- Riot.js - is the most light-weight user-interface (UI) framework available which is compatible with IE 8/9 and has good server-side rendering (which means pages load faster for slow devices like budget smart phones). see: https://github.com/dwyl/learn-riot
- Redis - the most popular in-memory data store which is essential
for building the fastest possible apps. read more: https://github.com/dwyl/learn-redis - ElasticSearch - the most feature-rich search engine. we use it to find things fast. Learn more: https://github.com/dwyl/learn-elasticsearch
Development Dependencies
We carefully select and only use well-maintained "pure" JavaScript modules in our development toolchain:
- Tape for testing: https://github.com/dwyl/learn-tape
- Istanbul for Code Coverage: https://github.com/dwyl/learn-istanbul
- Pre-commit for ensuring all commits pass strict quality checks before being pushed to GitHub. see: https://github.com/dwyl/learn-pre-commit
- GoodParts "linting" and checking code style is consistent: https://github.com/dwyl/goodparts
- CodeCov for detailed test/code coverage stats https://github.com/dwyl/learn-istanbul#tracking-coverage-as-a-service
- CodeClimate for tracking code quality: https://github.com/dwyl/learn-codeclimate
Continuous Integration
We use and recommend Travis-CI for Continuous Integration (CI). If you or anyone on your team are new to Travis-CI, checkout our beginners guide: https://github.com/dwyl/learn-travis
