Honeydew

An example app built on the CELP (Commanded, Elixir, LiveView, PostgreSQL) stack.

Use this example "Honey Do" list app to experiment with CQRS/ES in Commanded. The domain is pretty simple. It's a todo list with a little extra sauce allowing developers lots of creative freedom.

Setup

You'll need to have PostgreSQL setup and running on your machine. My favourite way to get PostgreSQL setup is via Docker Desktop. Once you have docker installed, you can use this command to get PostgreSQL setup on your machine.

docker run --rm --name pg-docker -e POSTGRES_PASSWORD=postgres -d -p 5432:5432 postgres

To start your Phoenix server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix setup
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

This app is not ready for production.

Blunt (Formerly CQRS_TOOLS)

For an example of this app ported to use blunt (Formerly cqrs_tools) checkout the with_blunt branch! If you have a local copy of the with_cqrs_tools branch, you'll want to update with the following commands.

git branch -m with_cqrs_tools with_blunt
git fetch origin
git branch -u origin/with_blunt with_blunt
git remote set-head origin -a
