Simple Chat Application API

Simple Chat Application API in Golang.
Developed to serve as a backend target for an AWS API Gateway Web Socket API, the API persists data to AWS DynamoDB. Also, it can optionally be configured to enable AWS X-Ray Tracing (by setting the AWS_XRAY_DAEMON_ADDRESS environment variable).

Deploy Development Server (Docker)

Deploy development server and local instance of AWS DynamoDB with docker-compose.

cd .docker
docker-compose up --build

# Stop the server and database
docker-compose down
