Full socket.io client and server example

To see a full explanation, read my answer on SO here: https://stackoverflow.com/a/24232050/778272.

How to use

Create a folder, run npm init -f on it and paste both server.js and client.js there (see files below). Needless to say, you must have Node.js installed on your system.

Install the required libraries:

ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key
# Don't add passphrase
openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
cat jwtRS256.key
cat jwtRS256.key.pub

// Code to encrypt data in sequelize fields

// We are using ascii85 as a way save on storage. Also, note that
// the space delimiter we are using is a bit of an abuse since in
// normal cases ascii85 will skip over it, but since we are using
// after encoding and before encoding, it shouldn't be an issue.
//
// Fields are broken down to facilitate unit testing.

1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
2. bundle
3. Run RAILS_ENV=production rake db:create db:migrate db:seed
4. Run rake secret and copy the output
5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
