telegram-auto

telegram parser for w_popularity.

Scrapes the public preview at https://t.me/s/<handle> — no auth, no API token, no MTProto. The same HTML response carries both the channel counters and the last ~20 posts inline.

Caveats

• Works only for public channels. User handles (t.me/<user>) have no /s/ preview — Telegram redirects them to a plain "Send Message" page, so FetchChannel and FetchRecentPosts return shared.ErrNotFound with a hint that the handle is not a public channel.
• Private channels and missing handles likewise return ErrNotFound.
• The preview embeds the most recent ~20 messages only. For deeper history you'd need MTProto or ?before= pagination (not implemented).
• Reactions and comments are not exposed in the preview; those fields stay at zero in PostSnapshot.
• Telegram's compact counters (1.2K, 5M, 2.1B) are parsed by multiplying the float prefix. There is some loss of precision for large numbers (Telegram itself rounds).

Usage

import parser "github.com/suenot/telegram-auto"

p := parser.New(parser.Config{HTTPTimeout: 15 * time.Second})
snap, err := p.FetchChannel(ctx, "durov")
posts, err := p.FetchRecentPosts(ctx, "durov", time.Now().Add(-24*time.Hour))

Strategy

• Primary: GET https://t.me/s/<handle> HTML scrape (this module).
• Fallback (not implemented): MTProto via gotd/td for private channels or deep history; Camoufox for anti-bot scenarios.
