# on any OS
docker run -d --restart unless-stopped --name postgresql -e POSTGRES_USER=test-user -e POSTGRES_PASSWORD=password -p 5432:5432 -v postgres_data:/var/lib/postgresql/data postgres:alpine

make sure it has successfully started up and is running

Initialize PostgreSQL Database

cd databases/diesel-async
cargo install diesel_cli --no-default-features --features postgres

echo DATABASE_URL=postgres://test-user:password@localhost:5432/test_db > .env
diesel setup
diesel migration run

The database will now be created in your PostgreSQL instance.

docker exec -i postgresql psql -U test-user -c "\l"

Running Server

cd databases/diesel-async
cargo run

# Started http server: 127.0.0.1:8080

Available Routes

`POST /items`

Inserts a new item into the PostgreSQL DB.

Provide a JSON payload with a name. Eg:

{ "name": "thingamajig" }

On success, a response like the following is returned:

{
  "id": "01948982-67d0-7a55-b4b1-8b8b962d8c6b",
  "name": "thingamajig"
}

Client Examples

http POST localhost:8080/items name=thingamajig

Using cURL:
