grammY bilan video yuklab oluvchi Telegram bot

Faqat grammY; fetch Node 18+ da o'rnatilgan. O'rnatiladigan skreping to'plami yo'q, tirik ushlab turiladigan brauzer yo'q.

npm install grammy

Kalit Authorization sarlavhasida bo'lgan bitta GET. AbortSignal.timeout sekin manbani handler'ingizni ushlab turishdan saqlaydi. Endpoint platformani URL'dan aniqlaydi, bot domen bo'yicha shoxlanmaydi.

const API = "https://api.saveapi.org/v1/download";

async function resolve(link) {
  const res = await fetch(API + "?url=" + encodeURIComponent(link), {
    headers: { Authorization: "Bearer sk_live_xxxx" },
    signal: AbortSignal.timeout(30_000),
  });
  return res.json();
}

message::url URL entity'li har qanday xabarga mos keladi; ctx.entities("url") matnini beradi. replyWithVideo va replyWithPhoto media URL'ni to'g'ridan-to'g'ri oladi — Telegram o'zi tortadi. medias[0].type ni tekshiring: slayd-shou yoki karusel — rasmlar, video emas.

import { Bot } from "grammy";

const bot = new Bot(process.env.BOT_TOKEN);

bot.on("message::url", async (ctx) => {
  const link = ctx.entities("url")[0].text;
  const data = await resolve(link);

  if (!data.success) {
    return ctx.reply(EXPLAIN[data.error.code] ?? "Try another link.");
  }

  const media = data.medias[0];
  return media.type === "video"
    ? ctx.replyWithVideo(media.url, { caption: data.meta?.title ?? "" })
    : ctx.replyWithPhoto(media.url);
});

bot.start();

Foydalanuvchilar kun bo'yi yopiq post va o'lik havola yuboradi. Barqaror kodlarni gaplarga xaritalang: "Bu akkaunt yopiq" degan bot boshqa havola oladi, "xato" degan bot jahlli xabar. Yopiq va yo'q post to'liq 1.5 emas, 0.1 kredit turadi.

const EXPLAIN = {
  PRIVATE_CONTENT: "That account is private — I can only fetch public posts.",
  MEDIA_NOT_FOUND: "That post has no media, or it was deleted.",
  UNSUPPORTED_PLATFORM: "I do not know that site yet.",
  QUOTA_EXCEEDED: "Out of credits.",
  UPSTREAM_TIMEOUT: "The source was slow. Send the link again.",
};

Birinchi yuborishdan keyin Telegram file_id beradi; uni qayta yuborish hech narsa yuklamaydi va kredit sarflamaydi. Media URL saqlash uchun noto'g'ri narsa — CDN havolalari imzolangan va bir necha soatda eskiradi.
