### Run Valkyrie Gleam Example with Docker Compose

Source: https://github.com/pevensie/valkyrie/blob/main/README.md

Commands to start a Redis-compatible database using Docker Compose for the example application and then execute the Valkyrie example application written in Gleam.

```bash
docker compose --profile valkey up -d
# You can also use profiles 'redis', 'keydb' or 'dragonfly'
gleam run -m valkyrie/example
```

### Set Up Valkyrie Development Environment and Run Tests

Source: https://github.com/pevensie/valkyrie/blob/main/README.md

Instructions to start a local Redis-compatible database for development and testing using Docker Compose, and how to run all tests sequentially against different profiles using the Mise package manager.

```bash
docker compose --profile valkey up -d
# You can also use profiles 'redis', 'keydb' or 'dragonfly'
```

```bash
mise run test
```

Instructions to add the Valkyrie package to a Gleam project using the gleam package manager.

```sh
gleam add valkyrie
```

### Initialize and Use Valkyrie Connection Pool in Gleam

Source: https://github.com/pevensie/valkyrie/blob/main/README.md

Demonstrates how to set up a Valkyrie connection pool as part of an application's supervision tree using Gleam's static supervisor. It shows how to obtain a named connection from the pool and perform basic Redis-compatible operations like setting and getting keys.

```gleam
import gleam/erlang/process
import gleam/option
import gleam/otp/static_supervisor as supervisor
import valkyrie

pub fn main() {
  // Create a name to interact with the connection pool once it's started under the
  // static supervisor.
  let pool_name = process.new_name("connection_pool")

  // Define a pool of 10 connections to the default Redis instance on localhost.
  let valkyrie_child_spec =
    valkyrie.default_config()
    |> valkyrie.supervised_pool(
      size: 10,
      name: option.Some(pool_name),
      timeout: 1000,
    )

  // Start the pool under a supervisor
  let assert Ok(_started) =
    supervisor.new(supervisor.OneForOne)
    |> supervisor.add(valkyrie_child_spec)
    |> supervisor.start

  // Get the connection now that the pool is started
  let conn = valkyrie.named_connection(pool_name)

  // Use the connection.
  let assert Ok(_) = echo valkyrie.set(conn, "key", "value", option.None, 1000)
  let assert Ok(_) = echo valkyrie.get(conn, "key", 1000)

  // Do more stuff...
}
```
