DB_PORT=5432;
DB_USERNAME=localuser;
USE_RABBITMQ=false;

5. hit http://localhost:8080/swagger-ui/index.html

the-react

1. setup the-spring locally at 8080

2. run npm install

3. run npm run start

the-express

1. run rabbitmq locally docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:4.0-management

2. run minio locally docker run -it --rm --name minio -p 9000:9000 -p 9001:9001 quay.io/minio/minio server /data --console-address ":9001"

3. in index.ts replace redis password and host with your redis account

to run on aws

ensure aws cli is logged in

ecs
