HTTP

The http block declares an HTTP server

Note: Unlike most blocks in a stack, this block does not use Docker - it uses ktor (opens in a new tab), as the Nebula http engine is already running Ktor.

This is a thin wrapper around Ktor routes (opens in a new tab). See the Ktor docs for more information.

stack {
    // port is optional, will pick a random port
    http(port = 9000) {
        get("/hello") { call ->
            call.respondText("Hello, World!")
        }
        post("/echo") { call ->
            val body = call.receiveText()
            call.respondText(body)
        }
        get("/users/{id}") { call ->
            val id = call.parameters["id"]
            call.respondText("User $id")
        }
        put("/update/{id}") { call ->
            val id = call.parameters["id"]
            val body = call.receiveText()
            call.respondText("Updated user $id with $body")
        }
        delete("/delete/{id}") { call ->
            val id = call.parameters["id"]
            call.respondText("Deleted user $id", status = HttpStatusCode.NoContent)
        }
    }
}
