piratetok_live

Connect to any TikTok Live stream and receive real-time events in Dart. No signing server, no API keys, zero dependencies.

import 'dart:io';
import 'package:piratetok_live/piratetok_live.dart';

void main() async {
  // Create client — zero dependencies, raw RFC 6455 WebSocket under the hood
  final client = TikTokLiveClient("username_here");

  // Register event handlers — data arrives as decoded protobuf maps
  client.on(EventType.chat, (evt) {
    final nick = evt.data?['user']?['uniqueId'] ?? '?';
    print('[chat] $nick: ${evt.data?['content']}');
  });

  client.on(EventType.gift, (evt) {
    final nick = evt.data?['user']?['uniqueId'] ?? '?';
    final gift = evt.data?['gift'] as Map<String, dynamic>?;
    final diamonds = gift?['diamondCount'] ?? 0;
    print('[gift] $nick sent ${gift?['name']} x${evt.data?['repeatCount']} ($diamonds diamonds)');
  });

  client.on(EventType.like, (evt) {
    final nick = evt.data?['user']?['uniqueId'] ?? '?';
    print('[like] $nick x${evt.data?['count']} (${evt.data?['total']} total)');
  });

  // Connect — handles auth, room resolution, WSS, heartbeat, reconnection
  await client.connect();
  exit(0);
}

Features

  • Zero signing dependency -- no API keys, no signing server, no external auth
  • Zero external dependencies -- only dart:io, dart:async, dart:convert, dart:typed_data
  • 64 decoded event types -- hand-written protobuf codec, no codegen
  • Raw WebSocket -- custom RFC 6455 implementation, bypasses dart:io WebSocket quirks
  • Auto-reconnection -- stale detection, exponential backoff, self-healing auth
  • DEVICE_BLOCKED self-healing -- 2s retry with fresh credentials + random UA rotation
  • Enriched User data -- badges, gifter level, moderator status, follow info, fan club
  • Sub-routed convenience events -- follow, share, join, liveEnded

Configuration

final client = TikTokLiveClient("username_here")
    .cdnEu()                             // EU / US / Global (default)
    .timeout(Duration(seconds: 15))
    .heartbeatInterval(Duration(seconds: 10)) // default 10s, also sent as heartbeat_duration
    .maxRetries(10)                       // consecutive failures, default 5 (reset after a 30s healthy session)
    .staleTimeout(Duration(seconds: 90))  // default 60s
    .userAgent("custom UA string")        // default: random from pool
    .cookies("sessionid=xxx; sid_tt=xxx") // only for 18+ room info
    .language("en")                       // default: system locale
    .region("US")                         // default: system locale
    .compress(false)                      // disable gzip for WSS payloads (default true)
    .proxy("socks5://127.0.0.1:1080");

Room info (optional, separate call)

import 'package:piratetok_live/piratetok_live.dart';

// Check if user is live
final result = await checkOnline("username_here");
print('room_id: ${result.roomId} anchor_id: ${result.anchorId}');

// Fetch room metadata (title, viewers, stream URLs)
final info = await fetchRoomInfo(result.roomId);

// 18+ rooms -- pass session cookies from browser DevTools
final info18 = await fetchRoomInfo(result.roomId,
    cookies: "sessionid=abc; sid_tt=abc");

Viewers

Every roomUserSeq event carries the counters and the top-viewers box — no cookies needed:

client.on(EventType.roomUserSeq, (evt) {
  evt.data!['viewerCount']; // in the room right now (goes up and down)
  evt.data!['totalUser'];   // unique viewers over the whole stream (only grows)
  for (final c in topViewers(evt.data!)) { // usually top 3, sorted by rank
    print('#${c['rank']} ${(c['user'] as Map)['nickname']} (${c['score']})');
  }
});

The full audience roster is a separate call. TikTok gates it behind a login, so session cookies are required for this call only — without them it throws SessionRequiredError:

final room = await checkOnline("username_here");
final audience = await fetchRoomAudience(room.roomId,
    anchorId: room.anchorId, cookies: "sessionid=abc; sid_tt=abc");
// audience.total, audience.anonymous, audience.viewers (rank, score, username, followerCount, ...)

Omit anchorId to resolve it from room info (one extra request).

Helpers

Stateful helpers for common patterns. Exported from the main package, never imported by the core pipeline.

GiftStreakTracker

Computes per-event gift deltas from TikTok's running totals. Combo gifts fire multiple events during a streak with cumulative repeatCount values -- this helper tracks active streaks and gives you the delta.

final tracker = GiftStreakTracker();

client.on(EventType.gift, (evt) {
  final e = tracker.process(evt.data!);
  if (e.isFinal) {
    print('streak done: ${e.totalGiftCount} gifts, ${e.totalDiamondCount} diamonds');
  } else if (e.eventGiftCount > 0) {
    print('ongoing: +${e.eventGiftCount} (+${e.eventDiamondCount} diamonds)');
  }
});

LikeAccumulator

Monotonizes TikTok's inconsistent total field on like events. Different server shards send stale values causing backwards jumps -- this helper accumulates from the reliable per-event count field.

final likes = LikeAccumulator();

client.on(EventType.like, (evt) {
  final s = likes.process(evt.data!);
  print('${s.accumulatedCount} likes accumulated (server says ${s.totalLikeCount})');
});

ProfileCache

Wraps sigi profile scraping with TTL cache and automatic ttwid management. Fetches HD avatars, follower counts, bio, verified status.

final cache = ProfileCache(ttlMs: 300000); // 5 min TTL (default)
final profile = await cache.fetch('username');
print('${profile.nickname} — ${profile.followerCount} followers');

How it works

  1. Resolves username to room ID via TikTok JSON API
  2. Fetches a ttwid cookie (retried up to 8× — TikTok only sets it intermittently) and opens a direct WSS connection (raw RFC 6455 socket)
  3. Sends protobuf heartbeats every heartbeatInterval (10s) to keep alive
  4. Decodes protobuf event stream into typed maps
  5. Auto-reconnects on stale/dropped connections, reusing ttwid + UA; both rotate only on DEVICE_BLOCKED or a connection that died within 30s
  6. connect() runs the whole session — its future completes after the final disconnect; EventType.connected fires once the room is resolved

All protobuf encoding/decoding is hand-written -- no .proto files, no codegen, no build-time tooling.

Examples

dart run example/basic_chat.dart <username>        # connect + print chat events
dart run example/online_check.dart <username>      # check if user is live
dart run example/stream_info.dart <username>       # fetch room metadata + stream URLs
dart run example/gift_streak.dart <username>       # gift combo tracking with diamond totals
dart run example/profile_lookup.dart [username]    # fetch profile metadata + avatars (cached)
dart run example/audience.dart <username> "sessionid=...; sid_tt=..."  # full viewer roster (login required)

Replay testing

Deterministic cross-lib validation against binary WSS captures. Requires testdata from a separate repo:

git clone https://github.com/PirateTok/live-testdata testdata
dart test

Replay tests fail if testdata is not found — they never pass on missing data. Set PIRATETOK_TESTDATA to point to a custom location. Offline unit tests (ttwid retry against a local responder, reconnect budget, top viewers, audience parsing) need no network.
