I m trying to create dynamic endpoints coming from a list I see from the docs how to add path params ``` book title bind GET to req gt Response invoke Status OK body GetBookDetails req path title author name latest bind GET to req gt Response invoke Status OK body GetAllBooks author = req path name last ``` But I m looking to be able to take a list of Strings at runtime and create paths dynamically with param for each ` book author character n ` ``` book key author key character key n key ``` Is this possible

"/book/{title}" bind GET to { req -> Response.invoke(Status.OK).body(GetBookDetails(req.path("title")) }
"/author/{name}/latest" bind GET to { req -> Response.invoke(Status.OK).body(GetAllBooks(author = req.path("name")).last()) }

But I’m looking to be able to take a list of Strings at runtime and create paths dynamically (with param) for each...

["book","author","character",..., "n"]

"/book/{key}"
"/author/{key}"
"/character/{key}"
...
"/{n}/{key}"

Is this possible?

yes - it's entirely possible because we do everything programmatically. just map over the list and create the list of HTTP handler bindings then compose them

Do you have any examples of something similar? I’m struggling with the kotlin syntax of how to get there.

import org.http4k.core.Method.GET
import org.http4k.core.Request
import org.http4k.core.Response
import org.http4k.core.Status.Companion.OK
import org.http4k.routing.bind
import org.http4k.routing.routes

fun main() {
    val endpoints = listOf("foo", "bar").map {
        "/$it" bind GET to { req: Request -> Response(OK) }
    }
    val app = routes(*endpoints.toTypedArray())

    println(app(Request(GET, "/foo")))
    println(app(Request(GET, "/bar")))
}
