### Basic Hummingbird App Setup

Source: https://hummingbird.codes

This snippet demonstrates the basic setup for a Hummingbird application, including router configuration and starting the service. It's suitable for simple 'Hello, World!' style applications.

```swift
import Hummingbird

let router = Router().get { req, context in
    return "Hello, Swift!"
}
let app = Application(router: router)
try await app.runService()

```

### Hummingbird Route with Database Interaction

Source: https://hummingbird.codes

This example shows how to define a GET route in Hummingbird that retrieves a video by its ID from a MongoDB database using the Meow package. It requires the 'id' parameter to be a 'Reference<Video>' and resolves it against a 'db' instance.

```swift
import Hummingbird
import Meow // From MongoKitten

router.get("/videos/:id") { req, context in
  let id = try context.parameters.require(
    "id",
    as: Reference<Video>.self
  )
  return try await id.resolve(in: db)
}

```
