Cratis is an Event Sourcing database built with ease of use, productivity, compliance and maintainability in mind. It provides the core server, referred to as the Kernel with a client SDK to access it (.NET only for the time being) and tooling built into it.

Read the documentation on our site https://cratis.io for all the details. For general guidance on the core values and principles we @ use, read more here.

If you want to jump into building this repository and possibly contributing, please refer to contributing.

If you prefer to browse the code in VSCode, you can do so by clicking here.

Make sure you have the following installed:

• Docker
• .NET Core 7

The sample consists of a backend and a frontend. Navigate to the Bank Sample folder.

Before running the microservice backend and frontend, we will need to run the Cratis Kernel.

docker compose up -d

This will bring up the Cratis Kernel and expose the following ports:

Within here you'll see a folder called Main, which represents the backend startup. Navigate to this and start the backend by running:

dotnet run

The frontend is located in the Web folder. While the backend is running in another terminal, navigate to that folder and start it by running:

yarn start:dev

Open a browser and navigate to http://localhost:9100/ and you can start playing around with the sample.

Note: The Cratis workbench is available http://localhost:8080/

If you're looking to either contribute or dive into the code by building and running the Cratis Kernel locally, you can read more here. You'll find issues to start with by going to here.
