JarCastingcomplate HTTP4K Adapter
This adapter connects HTTP4K with the templating engine complate.
Usage
Compiling and Installation
Unless this library becomes available via maven central (or others), it can be built and installed to the local maven repo:
./gradlew clean build
./gradlew install
Dependency
Library import:
dependencies {
compile 'com.github.complate:complate-http4k:0.1.1'
}
HTTP4K Example
Everything that is required to move an existing HTTP4K based application from another templating engine towards complate can be achieved by switching the templates to com.github.complate.ComplateTemplates.
Here is a more-or-less complete (working) base that shows how to use.
dependencies {
// Kotlin
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
// HTTP4K
compile "org.http4k:http4k-core:2.35.1"
compile "org.http4k:http4k-server-netty:2.35.1"
// complate Adapter
compile 'com.github.complate:complate-http4k:0.1.1'
}
package com.github.complate.http4k.demo
import com.github.complate.ComplateTemplates
import org.http4k.core.Method
import org.http4k.core.Response
import org.http4k.core.Status
import org.http4k.routing.bind
import org.http4k.server.Http4kServer
import org.http4k.server.Netty
import org.http4k.server.asServer
import org.http4k.template.TemplateRenderer
import org.http4k.template.ViewModel
import kotlin.concurrent.thread
val bundles = "src/main/resources/frontend"
fun main(args: Array<String>) {
val app = DemoApplication()
app.start()
Runtime.getRuntime().addShutdownHook(thread(start = false) { app.stop() })
}
data class Person(val name: String, val age: Int) : ViewModel
class DemoApplication {
private val server: Http4kServer
private val renderer: TemplateRenderer = ComplateTemplates().HotReload(bundles)
private val routes = org.http4k.routing.routes(
"/person" bind Method.GET to {
val viewModel = Person("Bob", 45)
val renderedView = renderer(viewModel)
Response(Status.OK).body(renderedView)
}
)
init {
server = routes.asServer(Netty(9000))
}
fun start() = server.start()
fun stop() = server.stop()
}
TODOs
Caching (file & class path) is not implemented at the moment:
class ComplateTemplates : Templates {
override fun Caching(baseTemplateDir: String): TemplateRenderer {
TODO("not implemented")
}
override fun CachingClasspath(baseClasspathPackage: String): TemplateRenderer {
TODO("not implemented")
}
}
This will hopefully added in a future version of the adapter (most likely v0.2.0).
