# 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.
The shared [Hummingbird](https://github.com/hummingbird-project/hummingbird) toolkit the platform's services build on: declarative routing, hardened HTTP middlewares, pre-rendered localized responses, and page and asset scaffolding.
## Overview
| Role | Types |
| --- | --- |
| Routing | `RouterController`, `RouteCollectionBuilder`, the `addController` extension on `RouterMethods` |
| Middlewares | `SecurityHeadersMiddleware`, `VaryMiddleware`, `RateLimitMiddleware`, `LocalizationMiddleware`, `NotFoundMiddleware` |
| Middlewares | `SecurityHeadersMiddleware`, `HTTPSRedirectMiddleware`, `TrailingSlashRedirectMiddleware`, `VaryMiddleware`, `RateLimitMiddleware`, `LocalizationMiddleware` (negotiating from a `lang` query parameter, then a leading path segment, then `Accept-Language`), `NotFoundMiddleware` |
| Pages and assets | `Page`, `Asset`, `AssetExtension`, `FingerprintAssets` |
| Link previews | `SocialCard`, its `Image`, and the `Tag` meta tags it derives |
| Structured data | `StructuredData`, the `Node`, `Property`, and `Value` types of its schema.org graph, and the open `Name` and `Kind` vocabularies |
| Analytics | `Analytics`, the tracker script `Attribute`s it derives, and the `origin` its preconnect hint targets |
| Responses | `CachedHTMLResponse`, `LocalizedHTMLCollectionResponse` |
| Link previews | `SocialCard`, its `locale` and the `alternateLocales` of its other language editions, its `Image` and `Style`, and the `Tag` meta tags it derives |
| Structured data | `StructuredData`, the `Node`, `Property`, and `Value` types of its schema.org graph, the open `Name` and `Kind` vocabularies, and the site-wide initializer building the `Organization`/`WebSite` pair |
| Analytics | `Analytics`, the `Event`s a page reports (with `tagging()` to apply one to any attribute-bearing HTML or SVG tag), the tracker script `Attribute`s it derives, the optional session `recorder` script paired with it, and the `origin` its preconnect hint targets |
| Responses | `CachedHTMLResponse`, and `LocalizedHTMLCollectionResponse` rendering one of them per catalog language |
| Contexts | `LocalizedRequestContext` |
| Constants | The `HTTPField.Name` header names, `Int.RateLimit` limits, and `String.Security` header values the middlewares default to |
## 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, the `document:` closure building a page for a locale, and a `Page` conformer's `metadata` plus its optional head concerns (`summary`, `canonicalURL`, `socialCard`, `structuredData`, `analytics`). URLs arrive fully formed and absolute; composing them stays with the page.
- **Types own their format; `Page` renders generically.** Each head concern derives its own render-ready representation`SocialCard.tags`, `StructuredData.payload`, `Analytics.attributes`and `Page` applies it without knowing the vocabulary. Page ``scripts`` and the tracker render as `defer`red head tags, with a `preconnect` hint for the tracker's cross-origin host.
- **Services fill the gaps once, via extensions.** A service restores its convenient call sites with retroactive extensions — the Website's `*+Defaults` extensions are the pattern. The open schema.org vocabularies extend the same way: the package declares the shared `Property.Name` and `Node.Kind` constants, and a service adds its own.
- **Method structs.** Single-operation types such as `FingerprintAssets` hold their lifetime-fixed configuration in `init` and take only per-call inputs in `callAsFunction`.

URLs arrive absolute and fully formed — composing them stays with the page. The same holds for request semantics: only the caller knows whether it negotiates the language or pins it by route, so `variesOnAcceptLanguage:` declares whether the responses carry `Vary: Accept-Language`.
- **Types own their format; `Page` renders generically.** Each head concern derives its own render-ready form`SocialCard.tags`, `StructuredData.payload`, `Analytics.attributes`which `Page` applies without knowing the vocabulary. A page's `scripts` and the tracker render as `defer`red head tags, the tracker preceded by a `preconnect` to its cross-origin host.
- **Nodes are joined by `@id`, not repetition.** A node another page must point at gets its identifier from a helper rather than a hand-spelled fragment — `organizationID(forSiteURL:)` names the node the site-wide initializer builds, and that initializer's `founder` takes such an identifier back. A service adds the helper for any node it owns, so neither side can drift.
- **Services fill the gaps once, via extensions.** A service restores its convenient call sites retroactively — the Website's `*+Defaults` are the pattern. The open schema.org vocabularies work the same way: the package declares the shared `Property.Name` and `Node.Kind` constants, a service adds its own.
- **Method structs.** Single-operation types such as `FingerprintAssets` take lifetime-fixed configuration in `init` and per-call inputs in `callAsFunction`.

## Testing
Every suite carries a tag for the kind of API it exercises — `.asset`, `.extension`, `.middleware`, `.protocol`, or `.type`, declared in `Tests/Utils/Extensions/Tag+Constants.swift` so test plans and summaries can slice a run by kind. A new suite adopts the tag matching its subject, or adds one when none fits.

## Requirements
- Swift 6.3 toolchain (`swift-tools-version:6.3`).
- macOS 15, matching the sibling packages (the services deploy to Linux containers; the packages carry no UI platforms).

- **The package reads no configuration.** The executable maps its `database.*` keys onto a `Driver` and hands it over; connection values arrive as plain data. The Website service's `ConfigReader+Properties` has the mapping.

> **Exception:** `Example` and `ExampleRepository` are `public` despite sitting under `Internal/`, so they are API a service can call. Move them to `Public/Models` and `Public/Repositories` when the first real domain model replaces them.
## Testing
The suite runs against the in-memory backend by default, so `swift test` needs no database. The PostgreSQL integration test is skipped unless `POSTGRES_TEST_HOST` points at one (with optional `POSTGRES_TEST_PORT`, `POSTGRES_TEST_NAME`, `POSTGRES_TEST_USERNAME`, and `POSTGRES_TEST_PASSWORD`); it reverts its migrations afterwards, leaving a shared database as it was found:
