Node.js web app for conducting experiments looking at the coevolution of language and meaning space. The app can be used on a computer, although it is designed for use on the iPad (other platforms have not been tested). Open the web app in Safari and add it to the home screen for the best experience.

Install Node.js on your server if you don't already have it, e.g.:

brew install node

Place the contents of this repo in a publicly accessible part of your server and change into the directory, e.g.:

cd public_html/coevolution/

Install the express and socket.io packages at this location using the Node Package Manager (npm):

npm install express
npm install socket.io

This should create a new node_modules directory containing the directories express and socket.io.

Modify the data_path variable in server.js to provide a path to where you want the results to be stored. Then modify the port variable in both server.js and client.js to some open port number (set to 9000 by default).

Make server.js executable and not publicly accessible, e.g.:

chmod 700 server.js

Start the Node.js server:

node server.js

Navigate to the URL on two iPads and start experimenting!
