IaC app & Library app

The project consists of two components:

1. Infrastructure as Code application based on AWS CDK (main)
2. Simple node.js app called Library App

Technologies used

IaC app: CloudFormation with CDK framework written in TypeScript

Library app:

• Frontend: JavaScript, CSS, HTML
• Backend: Node.js, Nginx, Docker, Docker Compose
• Database: MySQL

Library app

Components

1. Frontend:

• Static .js, .css, .html files under frontend/ directory

2. Backend:

• Reverse proxy built on Nginx
• Node.js backend app

3. MySQL database

Start app locally

1. Clone the repository
2. Edit .env file located in the root directory (MYSQL_USER, MYSQL_PASSWORD, MYSQL_ROOT_PASSWORD are mandatory)
3. In the root directory of the project run:

docker-compose up

That command will start nginx, backend and database containers. The backend app will be running on http://localhost:8080
