A Gleam HTTP service adapter for the Cowboy web server.
You may want to consider using the Mist web server instead as it has better performance, features type safe websockets, and is written entirely in Gleam. It is also supported by the Wisp web framework.
gleam add gleam_cowboyimport gleam/erlang/process
import gleam/http/cowboy
import gleam/http/response.{type Response}
import gleam/http/request.{type Request}
import gleam/bytes_tree.{type BytesTree}
// Define a HTTP service
//
pub fn my_service(request: Request(t)) -> Response(BytesTree) {
let body = bytes_tree.from_string("Hello, world!")
response.new(200)
|> response.prepend_header("made-with", "Gleam")
|> response.set_body(body)
}
// Start it on port 3000!
//
pub fn main() {
cowboy.start(my_service, on_port: 3000)
process.sleep_forever()
}Cowboy does not support duplicate HTTP headers so any duplicates specified by the Gleam HTTP service will not be sent to the client.
