Serving HTML

Scalatags

You can return a scalatags doctype directly in the Response.withBody().
Let's make a simple HTML page that greets the user.
Create a file html.sc and paste this code into it:

//> using scala "3.7.0"
//> using dep ba.sake::sharaf-undertow:0.10.0

import scalatags.Text.all.*
import ba.sake.sharaf.*
import ba.sake.sharaf.undertow.UndertowSharafServer

val routes = Routes:
  case GET -> Path() =>
    Response.withBody(IndexView)
  case GET -> Path("hello", name) =>
    Response.withBody(HelloView(name))

UndertowSharafServer("localhost", 8181, routes).start()

println(s"Server started at http://localhost:8181")

def IndexView = doctype("html")(
  html(
    p("Welcome!"),
    a(href := "/hello/Bob")("Go to /hello/Bob")
  )
)

def HelloView(name: String) = doctype("html")(
  html(
    p("Welcome!"),
    div("Hello ", b(name), "!")
  )
)

and run it like this:

scala-cli html.sc

Go to http://localhost:8181
to see how it works.

Hepek Components

Sharaf supports the hepek-components too.
Hepek wraps scalatags with helpful utilities like Bootstrap 5 templates, form helpers etc. so you can focus on the important stuff.
It is plain scala code as a "template engine", so there is no separate language you need to learn.

object IndexView extends HtmlPage:
  override def pageContent = div(
    p("Welcome!"),
    a(href := "/hello/Bob")("Hello world")
  )

class HelloView(name: String) extends HtmlPage:
  override def pageContent =
    div("Hello ", b(name), "!")

scala-cli html.sc
