• OpenAPI specification on eventhub-ingest.ard.de/openapi
• Internal documentation in Confluence

Get involved

• Join ard-eventhub/discussions for ongoing topics about formats, etc.
• Join #eventhub in the ARD Entwickler Slack

Modules

This project will include two modules: Ingest and API. The first development step is to only supply the Ingest service. Each module uses their own endpoints and checks, while some parts are shared across both (utils). They also both have their own Dockerfiles to start the appropriate service.

Ingest

The Ingest service is responsible for receiving and publishing events and managing subscriptions. You'll find the core code in ./src/ingest/.

Local Setup

This project uses bun as package manager and runtime environment. Please note that this only applies to the package manager and CLI commands. JavaScript still uses the 'traditional' node runtime. Check the Bun documentation for installation instructions.

To install dependencies run:

bun install

To check for minor updates:

bun update
