Default maximum size in bytes for the incoming webhook request body.

Telegram updates are small, so 4MB is plenty while keeping a sane upper bound. Use handle_bot_with_limit to override it.

A handler to process incoming requests from the Telegram API directly on top of mist, without wisp — for minimalistic deployments.

It checks the webhook path, validates the secret token, decodes the incoming update, and dispatches it to the bot in a separate process so the 200 OK response is returned immediately (Telegram waits for the response before sending the next update).

import gleam/http/request.{type Request}
import gleam/http/response.{type Response}
import mist.{type Connection, type ResponseData}
import telega.{type Telega}
import telega_mist

fn handle_request(
  req: Request(Connection),
  bot: Telega(session, error, dependencies),
) -> Response(ResponseData) {
  use <- telega_mist.handle_bot(telega: bot, req:)

  // Your other routes here...
  response.new(404) |> response.set_body(mist.Bytes(bytes_tree.new()))
}

Same as handle_bot, but lets you set the maximum request body size in bytes.
