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

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

npm install
node server.js

pip install -r requirements.txt
python server.py

ruby server.rb

php server.php

go run server.go

cpan Mojolicious
perl server.pl

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

You can change the port number by setting the $PORT environment variable before invoking any of the scripts above, e.g.,

PORT=3001 node server.js
