cqrs-demo

A demo application using the cqrs-es framework with a backing postgres repository.

Now using the Axum server for a much simpler layout.

Requirements

• rust 1.53 or greater
• docker & docker-compose for starting an instance of Postgres
• postman or curl (or your favorite Restful client)

Alternatively, if a standard Postgres instance is running locally it can be utilized instead of the docker instance, see the init script for the expected table configuration.

Installation

Clone this repository

git clone https://github.com/serverlesstechnology/cqrs-demo

Enter the project folder and start a docker instance of PostgreSql

cd cqrs-demo
docker-compose up -d

Start the application

cargo run

Call the API, the easiest way to do this is to import the provided postman collection into your Postman client or the test_api.sh curl script found in the curl directory. Note that the command calls are configured to return a 204 status with no content, only the query call will return a 200 OK response with a body. For feedback on state you should call a query.
