This is the frontend and backend code that powers Digital Maneuver.
The frontend is just a few HTML and CSS files. It's designed to load very quickly on mobile devices with limited bandwidth. CSS is modeled after BMFW.
The backend is a hackish service that can facilitate adding emails to a SendGrid contact list. There are no tests but it seems to work, so YMMV. This was not designed for production, low-latency, etc.
The backend can run on a local machine, VPS, etc. or also as an AWS Lambda function. If you set the RUN_AS_LAMBDA environment variable to be TRUE then the code path will behave as though it's running on AWS Lambda. Rate limiting is handled via AWS API Gateway.
