Experience
Static Website Builder
This was a personal experiment, that was the seed for how Foureyes has been making custom front-end static websites for clients. This allows us to generate front-end sites very quickly, which is intended to be hosted on Amazon S3 and CloudFront. Execute 'docker-compose up' to build, install libraries, and start running a development server. Docker and Docker Compose are needed to be able to run this code.
