Combined with Swift's multi-line strings and string interpolation, you can generate dynamic HTML pages directly from your route handlers. ## Basic HTML Response ```swift title="Simple HTML Page" theme={null} await server.get("/") { _ in .html(""" Welcome

Welcome to Prism

A native Swift server framework.

""") } ``` ## Dynamic Content Swift's string interpolation makes it natural to inject data: ```swift title="Dynamic HTML" theme={null} await server.get("/users/:id") { request in let id = request.parameters["id"] ?? "?" let user = try await fetchUser(id: id) return .html(""" \(user.name)

\(user.name)

Email: \(user.email)

Member since: \(user.createdAt)

""") } ``` ## Reusable Layout Functions Keep your HTML DRY with layout functions: ```swift title="Layout Helper" theme={null} func layout(title: String, body: String) -> String { """ \(title) — MyApp
\(body)
""" } await server.get("/") { _ in .html(layout(title: "Home", body: "

Welcome

Hello, world!

")) } await server.get("/about") { _ in .html(layout(title: "About", body: "

About

Built with Prism.

")) } ``` ## Rendering Lists ```swift title="HTML Table from Data" theme={null} await server.get("/dashboard") { _ in let items = try await fetchRecentOrders() let rows = items.map { order in "\(order.id)\(order.customer)$\(order.total)" }.joined(separator: "\n") return .html(layout(title: "Dashboard", body: """

Recent Orders

\(rows)
IDCustomerTotal
""")) } ``` Always escape user-provided content before inserting it into HTML to prevent XSS attacks. Swift's string interpolation does **not** auto-escape HTML entities. Replace `<`, `>`, `&`, and `"` with their HTML entity equivalents. For API-first applications, use `.html()` primarily for admin dashboards, error pages, and occasional server-rendered pages. Pair it with [Content Negotiation](/server/content/content-negotiation) to serve HTML to browsers and JSON to API clients from the same endpoint.
