This example is based on the ideas in this blog post. The value here is that the business logic can be unit tested independently from the database layer. Otherwise it is identical to the todos example.

Setup

Run docker-compose up -d to run Postgres in the background.

Declare the database URL, either by exporting it:

export DATABASE_URL="postgres://postgres:password@localhost/todos"

or by making a .env file:

cp .env.example .env

Create the database.
```
$ sqlx db create
```
Run sql migrations
```
$ sqlx migrate run
```

Usage

Add a todo

cargo run -- add "todo description"

Complete a todo.

cargo run -- done <todo id>

List all todos

cargo run

Cleanup

To destroy the Postgres database, run:

docker-compose down --volumes
