Example – To-Do App

This example shows how to implement a "todo list" app. The app consists of a "todo" server and a client that sends commands to the server.

• list.go implements the "todo list" aggregate
• events.go defines and registers the "todo list" events
• commands.go defines and registers the "todo list" commands
• counter.go implements a read model projection
• cmd/server is the server app
• cmd/client is the client app

Backends

• NATS Core (Event Bus)
• MongoDB (Event Store)

Build & Run

Requires Docker.

Default setup

make build && make default

Debounced projection

This setup sets the TODO_DEBOUNCE environment variable to 1s, resulting in a single "batch"-update of the Counter projection.

make build && make debounce
