matusnovak/serverless-aws-node-bootstrap-vue

This is a Serverless example using Node.js as the backend and Bootstrap-vue (Bootstrap 4 + Vue.js 2.4 - without webpack) as the front end. This is a slightly more advanced example showing a simple Post/Comment web app, including user authentication. Additionally, both the front end nad back end are served through the API Gateway, no need to use AWS CloudFront.
