## What it is
A tutorial sample app demonstrating isomorphic (universal) JavaScript, built as a small Express blog that renders pages on the server and then renders subsequent navigation client-side with React, Director, and Superagent. It accompanies an Airbnb blog post on isomorphic JavaScript concepts.

## Use cases
- learn isomorphic javascript concepts
- example of server-side rendering with react
- how to share code between client and server
- sample express app with client-side routing via pushstate
- understand universal javascript app architecture
- tutorial on rendering react on the server

## When to choose
- you want a minimal, readable example of isomorphic JavaScript with React and Express
- you are learning how server rendering plus pushState navigation fit together
- you want a historical reference for pre-Next.js universal JS patterns

## When to avoid
- you need a production-ready or maintained starter kit - the project is unmaintained since 2016
- you want modern tooling - it uses old Node 0.10, Grunt, and Browserify
- you need a full framework rather than a teaching example
