This is the React comment box example from the React tutorial.

To use

There are several simple server implementations included. They all serve static files from public/ and handle requests to comments.json to fetch or add data. Start a server with one of the following:

Node-Express

npm install
node server.js

Node-Koa-Mongoose

npm install
node --harmony koa-mongoose-server.js

Python

pip install -r requirements.txt
python server.py

Ruby

PHP

Go

And visit http://localhost:3000/. Try opening multiple tabs!
