# Infrastructure
|
||
|
|
The shared [Hummingbird](https://github.com/hummingbird-project/hummingbird) toolkit the **Loud** services build on: declarative routing, hardened HTTP middlewares, pre-rendered localized HTML responses, and the page and asset scaffolding.
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
The package provides, grouped by role:
|
||
|
|
|
||
|
|
| Role | Types |
|
||
|
|
| --- | --- |
|
||
|
|
| Routing | `RouterController`, `RouteCollectionBuilder`, the `addController` extension on `RouterMethods` |
|
||
|
|
| Middlewares | `SecurityHeadersMiddleware`, `VaryMiddleware`, `RateLimitMiddleware`, `LocalizationMiddleware`, `NotFoundMiddleware` |
|
||
|
|
| Pages and assets | `Page`, `Asset`, `AssetExtension`, `FingerprintAssets` |
|
||
|
|
| Responses | `CachedHTMLResponse`, `LocalizedHTMLCollectionResponse` |
|
||
|
|
| Contexts | `LocalizedRequestContext` |
|
||
|
|
|
||
|
|
## Design rules
|
||
|
|
The package holds only what every service can reuse; anything a service owns is injected, never referenced:
|
||
|
|
|
||
|
|
- **No site-specific content.** No page markup, no asset catalog, no `Bundle.module` lookups. A type that needs a service's content takes it as a parameter: the `bundle:` whose String Catalog names the supported languages (`LocalizationMiddleware`, `LocalizedHTMLCollectionResponse`, `NotFoundMiddleware`), the `document:` closure that builds a page for a locale, and the `metadata` requirement through which a `Page` conformer supplies its icon links and theme colors.
|
||
|
|
- **Services fill the gaps once, via extensions.** A service restores its convenient call sites with retroactive extensions — the Website's `Page+Defaults`, `LocalizationMiddleware+Defaults`, and `NotFoundMiddleware+Defaults` are the pattern to follow.
|
||
|
|
- **Method structs.** Single-operation types such as `FingerprintAssets` hold their lifetime-fixed configuration in `init` and take only per-call inputs in `callAsFunction`.
|
||
|
|
|
||
|
|
## Layout
|
||
|
|
Sources are split by visibility, then by kind, one type per file:
|
||
|
|
|
||
|
|
```
|
||
|
|
Sources/Public/<Kind>/ public API (Protocols, Middlewares, Responses, …)
|
||
|
|
Sources/Internal/<Kind>/ implementation details (e.g. FNV1aHash)
|
||
|
|
Tests/Cases/… mirrors the source layout
|
||
|
|
Tests/Utils/… stubs and test-only extensions
|
||
|
|
```
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
- Swift 6.3 toolchain (`swift-tools-version:6.3`).
|
||
|
|
- macOS 15, matching the sibling `Localization` and `Persistence` packages (the services deploy to Linux containers; the packages carry no UI platforms).
