    This was written to provide a simple serverless backend for a widget which displays live updating comments on a signup page. 
    The frontend can simple call $.post to add a comment, and $.get to retrieve the latest comments.
    You need a Redis instance somewhere, you can get a free 30MB one from Redis Labs.
    You'll also need to configure a AWS API Gateway endpoint which invokes this function for GET and POST requests

# This works by injecting SASS variables before the main template. As long as they are not

# I've implemented it at the client (tenant) level, but it could equally be more granular, at 
# level of some other entity in your application.
