Intro to Ktor: The HTTP server for Kotlin

Now, if we need to generate extra refined content material from that endpoint, like an inventory of quotes and their authors, we are able to swap to utilizing Ktor’s HTML DSL. First, we’d like two extra imports, that are already a part of the mission as a result of we included the DSL within the generated mission:

import io.ktor.server.html.*
import kotlinx.html.*

And we are able to generate our response like so:

routing {
  get("/") {
    name.respondHtml {
      head {
        title("Quotes")
      }
      physique {
        h1 { +"Quotes to Reside By" }
        ul {
          listOf(
            "This Thoughts is the matrix of all matter." to "Max Planck",
            "All religions, arts and sciences are branches of the identical tree." to "Albert Einstein",
            "The thoughts is all the pieces. What you assume you turn into." to "Buddha"
          ).forEach { (quote, writer) ->
       li {
         p { +quote }
         p { +"― $writer" }
       }
     }
   }
 }

That is utilizing the HTML builder capabilities from Ktor, and it showcases a few of the flexibility in Kotlin’s useful syntax. The DSL capabilities that correspond to HTML tags are readily comprehensible, and we create the identical nested construction we’d with plain HTML. In curly braces, we outline the content material nested inside every tag. It may be extra markup, textual content, variables or some mixture.
