TikTok-Live-Connector

A Node.js library to receive live stream events such as comments and gifts in realtime from TikTok LIVE by connecting to TikTok's internal Webcast push service. This package includes a wrapper that connects to the Webcast service using just the username (@uniqueId). This allows you to connect to your own live chat as well as the live chat of other streamers. No credentials are required. Besides Chat Comments, other events such as Members Joining, Gifts, Subscriptions, Viewers, Follows, Shares, Questions, Likes and Battles can be tracked.

Note

This is not a production-ready API. It is a reverse engineering project. Use the WebSocket API for production.

Table of Contents

Getting Started

  1. Install the package via NPM
npm i tiktok-live-connector
  1. Create your first TikTok LIVE chat connection
// Username of someone who is currently live
import { TikTokLiveConnection, WebcastEvent } from 'tiktok-live-connector';

const tiktokUsername = 'officialgeilegisela';

// Create a new wrapper object and pass the username
const connection = new TikTokLiveConnection(tiktokUsername);

// Connect to the chat (await can be used as well)
connection.connect().then(state => {
    console.info(`Connected to roomId ${state.roomId}`);
}).catch(err => {
    console.error('Failed to connect', err);
});

// Define the events that you want to handle
// In this case we listen to chat messages (comments)
connection.on(WebcastEvent.CHAT, data => {
    console.log(`${data.user.uniqueId} (userId:${data.user.uniqueId}) writes: ${data.comment}`);
});

// And here we receive gifts sent to the streamer
connection.on(WebcastEvent.GIFT, data => {
    console.log(`${data.user.uniqueId} (userId:${data.user.userId}) sends ${data.giftId}`);
});

// ...and more events described in the documentation below

Params and Options

To create a new TikTokLiveConnection object the following parameters can be specified.

TikTokLiveConnection(uniqueId, [options])

Param Name Required Description
uniqueId Yes The unique username of the broadcaster. You can find this name in the URL.
Example: https://www.tiktok.com/@officialgeilegisela/live becomes officialgeilegisela. The leading @ and the full URL form are also accepted.
options No Optional connection properties. Defaults are applied when a value is not specified.

signApiKey (default: undefined)
Euler Stream API key. When provided, it is written to the global SignConfig.apiKey before the underlying Euler client is created. Ignored when eulerApiInstance is passed.

eulerApiInstance (default: undefined)
Pre-built EulerStreamApiClient to use for all sign-server traffic. Takes precedence over signApiKey.

session (default: undefined)
Authenticated session bundle. Pass session.cookie to seed the cookie jar with sessionid and tt-target-idc, and/or session.oAuthToken to send an OAuth token to the sign server. Required when authenticateWs or useMobile is true. See Authenticated Connection.

authenticateWs (default: false)
Forward the session cookies or OAuth token to the sign server so the WebSocket is authenticated. Disabled by default since signing is done by a third-party service; enabling it sends your session credentials to that service.

useMobile (default: false)
Use the mobile WebSocket flow. Implies authenticateWs: true and requires session.cookie.

processInitialData (default: true)
Decode and emit the message batch returned in the initial sign response (recent chat history etc.).

fetchRoomInfoOnConnect (default: true)
Fetch room info during connect. If the streamer is not currently live the connect rejects with UserOfflineError. The fetched info is stored on connection.roomInfo and is also accessible via fetchRoomInfo().

enableExtendedGiftInfo (default: false)
Fetch the room gift list during connect so WebcastGiftMessage events carry an extendedGiftInfo field with name, cost, and image data.

clientPresets (default: randomized)
Pre-built { device, screen, location } presets. Defaults to a freshly randomized set from getRandomPresets().

webClientOptions (default: {})
Extra options forwarded to the underlying got HTTP client (proxy agent, timeout, etc.). Headers and search params from this object are merged with the defaults; transport-only fields are passed through. See Proxied Connection.

wsClientOptions (default: {})
Extra options forwarded to the underlying ws WebSocket client. See Proxied Connection.

webConfigOverrides (default: {})
Partial overrides for the resolved WebcastWebConfigDefaults used by the HTTP client. Use this to customize DEFAULT_HTTP_CLIENT_PARAMS, DEFAULT_HTTP_CLIENT_HEADERS, etc.

wsConfigOverrides (default: {})
Partial overrides for the resolved WebcastWebSocketConfigDefaults used by the WebSocket client. Use this to customize DEFAULT_WS_CLIENT_PARAMS or DEFAULT_WS_CLIENT_HEADERS.

Example Options

const tikTokLiveConnection = new TikTokLiveConnection(tiktokUsername, {
    signApiKey: 'your-api-key',
    processInitialData: false,
    enableExtendedGiftInfo: true,
    webConfigOverrides: {
        DEFAULT_HTTP_CLIENT_PARAMS: {
            app_language: 'en-US',
            device_platform: 'web_pc'
        },
        DEFAULT_HTTP_CLIENT_HEADERS: {
            'X-Custom-Header': 'value'
        }
    },
    wsConfigOverrides: {
        DEFAULT_WS_CLIENT_PARAMS: {
            app_language: 'en-US'
        },
        DEFAULT_WS_CLIENT_HEADERS: {
            'X-Custom-Header': 'value'
        }
    },
    webClientOptions: {
        timeout: { request: 10000 }
    },
    wsClientOptions: {
        handshakeTimeout: 10000
    }
});

Methods

Method Name Description
connect([roomId]) Connects to the live stream chat. Returns a Promise<TikTokLiveConnectionState> that resolves when the WebSocket is open and the room has been entered. Pass an explicit roomId to skip room-id resolution.
disconnect() Closes the WebSocket and waits for the close event before resolving. Safe to call even when not connected.
sendMessage(content, [roomId]) Sends a chat message to the connected room (or to roomId if provided). Requires signApiKey and an authenticated session. See Send Messages.
fetchRoomId([uniqueId]) Resolves the room id for the configured username (or for uniqueId if provided). Tries HTML scrape, then the TikTok API, then Euler Stream as a fallback.
fetchIsLive([uniqueId]) Resolves whether the user is currently live. Same fallback chain as fetchRoomId.
waitUntilLive([seconds], [abortSignal]) Polls fetchIsLive every seconds seconds (minimum 30) until the streamer goes live. Reject via abortSignal to cancel.
fetchRoomInfo([roomId]) Fetches room info from TikTok's webcast API. Caches the result on connection.roomInfo. Callable without an active connection. See Retrieve Room Info.
fetchAvailableGifts() Fetches the room gift list. Caches on connection.availableGifts. Callable without an active connection. See Retrieve Available Gifts.

Properties

Property Name Description
webClient: WebcastHttpClient The HTTP client used to talk to TikTok's web and webcast APIs. Holds the cookie jar, the merged client params, and the merged client headers.
apiClient: EulerStreamApiClient The Euler Stream API client used for sign-server traffic and other premium endpoints. Equivalent to webClient.apiClient.
wsClient: WebcastWebSocketClient | null The active WebSocket client. null until the connection is established and after disconnect.
options: TikTokLiveConnectionMutableOptions The subset of options retained on the instance (processInitialData, fetchRoomInfoOnConnect, enableExtendedGiftInfo, authenticateWs, useMobile).
roomInfo: RoomInfo | null The room info object cached from the most recent fetchRoomInfo() call (or from connect, when fetchRoomInfoOnConnect is true).
availableGifts: RoomGiftInfo | null The cached gift list. Populated when enableExtendedGiftInfo is true or after manually calling fetchAvailableGifts().
isConnecting: boolean True while connect() is in flight.
isConnected: boolean True after a successful connect, until the WebSocket closes.
clientParams: Record<string, string> Live URI parameters sent with every webClient request. Mutating this changes outgoing query strings.
roomId: string The currently bound room id. Empty string until connect resolves or fetchRoomId() is called.
state: TikTokLiveConnectionState Snapshot containing isConnected, isConnecting, roomId, roomInfo, and availableGifts.

Signing Configuration

WebSocket URL signing is delegated to the Euler Stream sign server via the @eulerstream/euler-api-sdk package. Configuration is held on the mutable SignConfig singleton.

For most users, passing signApiKey to the TikTokLiveConnection constructor is enough. It writes the key to SignConfig.apiKey before the underlying Euler client is built.

For advanced cases (custom sign-server URL, extra headers, JWT auth), mutate SignConfig directly before constructing your first connection:

import { SignConfig } from 'tiktok-live-connector';

SignConfig.apiKey = 'your api key'; // An API key created at https://www.eulerstream.com
SignConfig.basePath = 'https://your-custom-sign-server.com';
SignConfig.baseOptions = SignConfig.baseOptions || {};
SignConfig.baseOptions.headers = {
    ...(SignConfig.baseOptions.headers || {}),
    'X-Custom-Header': 'Custom-Header-Value'
};

Important

SignConfig is read once when the underlying Euler client is first instantiated and the result is cached. Mutate it before constructing the first TikTokLiveConnection, or pass an explicit eulerApiInstance to bypass the cache.

Accessing TikTok LIVE Routes

All HTTP route handlers live in the global RouteConfig registry and are also exported individually. Each route is a function that accepts a single options object and returns a Promise resolving to the route's response. The currently registered routes are:

  • fetchRoomInfo (TikTok webcast API)
  • fetchRoomGifts (TikTok webcast API)
  • fetchRoomInfoFromApiLive (TikTok web API)
  • fetchRoomInfoFromHtml (HTML scrape with SIGI_STATE extraction)
  • fetchRoomIdFromProvider (Euler Stream)
  • fetchRoomInfoFromProvider (Euler Stream)
  • fetchSignedWebSocketFromProvider (Euler Stream)
  • fetchWebcastSignatureFromProvider (Euler Stream)
  • sendRoomChatFromProvider (Euler Stream)
  • fetchRoomIdComposite (HTML, then API, then Euler fallback)
  • fetchIsLiveComposite (HTML, then API, then Euler fallback)

Example Usage

Routes need a webClient (and an apiClient for Euler routes), both of which are exposed on a TikTokLiveConnection instance:

import { TikTokLiveConnection, RouteConfig } from 'tiktok-live-connector';

const connection = new TikTokLiveConnection('officialgeilegisela');

const sigiState = await RouteConfig.fetchRoomInfoFromHtml({
    webClient: connection.webClient,
    uniqueId: 'officialgeilegisela'
});

console.log('SIGI_STATE liveRoom:', sigiState.liveRoom);

Swapping a Route Implementation

You can replace any handler in RouteConfig to inject custom behavior (caching, alternate sign provider, proxying through your own backend, etc.):

import { RouteConfig } from 'tiktok-live-connector';

const original = RouteConfig.fetchSignedWebSocketFromProvider;
RouteConfig.fetchSignedWebSocketFromProvider = async (args) => {
    console.log('signing for room', args.roomId);
    return original(args);
};

Accessing 3rd-Party (Euler Stream) Routes

The Euler Stream API client is exposed as connection.apiClient. It wraps every endpoint published by the @eulerstream/euler-api-sdk package, including premium and analytics endpoints not bundled into RouteConfig.

Example 1: Fetching Rate Limits

import { TikTokLiveConnection } from 'tiktok-live-connector';

const connection = new TikTokLiveConnection('officialgeilegisela', {
    signApiKey: 'your-api-key'
});

const response = await connection.apiClient.webcast.getRateLimits();
console.log('Rate Limits:', response.data);

Example 2: Using JWT Authentication

When running the connector in a client-facing environment (bundled desktop app, browser worker, etc.) you should not ship your raw API key. Mint a short-lived JWT on your server and hand that to the client instead.

Server-Side

import { SignConfig, createEulerClient } from 'tiktok-live-connector';

SignConfig.apiKey = 'your_server_side_api_key';
const apiClient = createEulerClient();

const res = await apiClient.authentication.createJWT(
    122, // Your account ID
    {
        limits: { minute: 5, hour: 5, day: 5 },
        expireAfter: 60 * 60 * 2 // 2 hours, the maximum accepted value
    }
);

console.log('Generated JWT:', res.data.token);

Client-Side

import { SignConfig, TikTokLiveConnection } from 'tiktok-live-connector';

SignConfig.baseOptions = SignConfig.baseOptions || {};
SignConfig.baseOptions.headers = {
    ...(SignConfig.baseOptions.headers || {}),
    'x-jwt-key': 'generated-jwt-key'
};

const connection = new TikTokLiveConnection('tv_asahi_news');

Events

A TikTokLiveConnection object has the following events which can be handled with an event listener.

The simplest event handler is a connect event:

const connection = new TikTokLiveConnection('officialgeilegisela');
connection.on(ControlEvent.CONNECTED, () => console.log("Connected!"));

Control Events:

Message Events:

Control Events

connected

Triggered when the connection is successfully established.

connection.on(
    ControlEvent.CONNECTED,
    (state: TikTokLiveConnectionState) => {
        console.log(`Hurray! Connected to roomId ${state.roomId}`);
        console.log(`Room info loaded: ${Boolean(state.roomInfo)}`);
    }
);

disconnected

Triggered when the connection gets disconnected. In that case you can call connect() again to have a reconnect logic. Note that you should wait a little bit before attempting a reconnect to to avoid being rate-limited.

connection.on(ControlEvent.DISCONNECTED, ({ code, reason }) => {
    console.log(`Disconnected :(${code})`);
    if (reason) {
        console.log(`Reason: ${reason}`);
    }
});

rawData

Triggered every time a protobuf encoded webcast message arrives. You can deserialize the binary object depending on the use case with protobufjs.

connection.on(ControlEvent.RAW_DATA, (messageTypeName, binary) => {
    console.log(messageTypeName, binary);
});

decodedData

Triggered every time a decoded message arrives. This is the same as the rawData event but the binary object is already decoded. You can use this event to handle the protobuf messages without the need of deserializing them yourself.

connection.on(ControlEvent.DECODED_DATA, (event: string, decodedData: any, binary: Uint8Array) => {
    console.log(event, decodedData);
});

websocketConnected

Will be triggered as soon as a WebSocket connection is established. The WebSocket client object is passed.

connection.on(ControlEvent.WEBSOCKET_CONNECTED, (client: TikTokWsClient) => {
    console.log('WebSocket open:', client.open);
});

websocketData

Triggered every time a WebSocket message arrives. This is the same as the rawData event but the binary object is

connection.on(ControlEvent.WEBSOCKET_DATA, (data: Uint8Array) => {
    console.log(`WebSocket bytes: ${data.length}`);
});

error

General error event. You should handle this.

connection.on(ControlEvent.ERROR, ({ info, exception }) => {
    console.error('Error!', info, exception);
});

Message Events

member

Triggered every time a new viewer joins the live stream.

connection.on(WebcastEvent.MEMBER, (data: WebcastMemberMessage) => {
    const uniqueId = data.user?.uniqueId;
    const nickname = data.user?.nickname;
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    if (uniqueId || nickname) {
        console.log('User joined the stream!');
    }
    console.log(`Viewers: ${data.memberCount}`);
});

chat

Triggered every time a new chat comment arrives.

connection.on(WebcastEvent.CHAT, (data: WebcastChatMessage) => {
    const uniqueId = data.user?.uniqueId;
    const nickname = data.user?.nickname;
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    if (data.comment) {
        console.log(`Comment: ${data.comment}`);
    }
});

gift

Triggered every time a gift arrives. You will receive additional information via the extendedGiftInfo attribute when you enable the enableExtendedGiftInfo option.

NOTE: Users have the capability to send gifts in a streak. This increases the repeatCount value until the user terminates the streak. During this time new gift events are triggered again and again with an increased repeatCount value. It should be noted that after the end of the streak, another gift event is triggered, which signals the end of the streak via repeatEnd:true. This applies only to gifts with giftType:1. This means that even if the user sends a giftType:1 gift only once, you will receive the event twice. Once with repeatEnd:false and once with repeatEnd:true. Therefore, the event should be handled as follows:

connection.on(WebcastEvent.GIFT, (data: WebcastGiftMessage) => {
    const giftType = data.giftDetails?.giftType;
    const giftName = data.giftDetails?.giftName;
    const uniqueId = data.user?.uniqueId;
    const nickname = data.user?.nickname;

    if (giftType === 1 && !data.repeatEnd) {
        // Streak in progress => show only temporary
        console.log('Gift streak in progress');
    } else {
        // Streak ended or non-streakable gift => process the gift with final repeat_count
        console.log('Gift streak ended or non-streakable gift');
    }
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    console.log(`GiftId: ${data.giftId}, repeatCount: ${data.repeatCount}`);
    if (giftName) {
        console.log(`Gift name: ${giftName}`);
    }
});

roomUser

Triggered every time a statistic message arrives. This message currently contains the viewer count and a top gifter list.

connection.on(WebcastEvent.ROOM_USER, data => {
    console.log(`Viewer Count: ${data.viewerCount}`);
    const topGifter = data.ranksList[0];
    if (topGifter?.user) {
        const uniqueId = topGifter.user.uniqueId;
        const nickname = topGifter.user.nickname;
        if (uniqueId) {
            console.log(`Top gifter uniqueId: ${uniqueId} (${topGifter.coinCount})`);
        }
        if (nickname) {
            console.log(`Top gifter nickname: ${nickname} (${topGifter.coinCount})`);
        }
    }
});

like

Triggered when a viewer sends likes to the streamer. For streams with many viewers, this event is not always triggered by TikTok.

connection.on(WebcastEvent.LIKE, data => {
    const uniqueId = data.user?.uniqueId;
    const nickname = data.user?.nickname;
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    console.log(`Likes: ${data.likeCount}, total likes: ${data.totalLikeCount}`);
});

social

Triggered every time someone shares the stream or follows the host.

connection.on(WebcastEvent.SOCIAL, data => {
    if (data.action) {
        console.log(`Social action: ${data.action}`);
    }
    const uniqueId = data.user?.uniqueId;
    const nickname = data.user?.nickname;
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    if (data.shareType || data.shareTarget) {
        console.log(`Share type: ${data.shareType}, share target: ${data.shareTarget}`);
    }
});

emote

Triggered every time a subscriber sends an emote (sticker).

connection.on(WebcastEvent.EMOTE, (data: WebcastEmoteChatMessage) => {

    const nickname = data.user?.nickname;
    if (uniqueId) {
        console.log(`User uniqueId: ${uniqueId}`);
    }
    if (nickname) {
        console.log(`User nickname: ${nickname}`);
    }
    const emoteId = data.emoteList[0]?.emoteId;
    if (emoteId) {
        console.log(`Emote id: ${emoteId}`);
    }
});

        }
        if (envelope.sendUserName) {
            console.log(`From: ${envelope.sendUserName}`);

    console.log(roomInfo);
    console.log(`Stream started timestamp: ${roomInfo.create_time}, Streamer bio: ${roomInfo.owner.bio_description}`);
    console.log(`HLS URL: ${roomInfo.stream_url.hls_pull_url}`); // Can be played or recorded with e.g. VLC
}).catch(err => {
    console.error(err);
});

Retrieve Available Gifts

const connection = new TikTokLiveConnection('@username');

connection.fetchAvailableGifts().then((giftList: RoomGiftInfo) => {
    console.log(giftList);
    giftList.forEach(gift => {
        console.log(`id: ${gift.id}, name: ${gift.name}, cost: ${gift.diamond_count}`)
    });
}).catch(err => {
    console.error(err);
})

Proxied Connection

The HTTP layer uses got and the WebSocket layer uses ws. Both accept a Node http.Agent, which makes hpagent the recommended proxy integration. hpagent is already a direct dependency of this package, so no extra install is required.

HTTP Client (got) via webClientOptions

got accepts an agent map keyed by protocol (http, https, http2). Provide proxy agents for each protocol the connector talks to:

import { TikTokLiveConnection } from 'tiktok-live-connector';
import { HttpProxyAgent, HttpsProxyAgent } from 'hpagent';

const proxy = 'http://user:pwd@host:8080';

const connection = new TikTokLiveConnection('@username', {
    webClientOptions: {
        agent: {
            http: new HttpProxyAgent({ proxy, keepAlive: true }),
            https: new HttpsProxyAgent({ proxy, keepAlive: true })
        }
    }
});

This routes all TikTok web/webcast HTTP traffic (room id, room info, gift list, HTML scrape, sign requests) through the proxy.

WebSocket Client (ws) via wsClientOptions

ws accepts a single agent (a Node http.Agent). Since the WebSocket upgrade goes over wss://, use the HTTPS variant:

import { TikTokLiveConnection } from 'tiktok-live-connector';
import { HttpProxyAgent, HttpsProxyAgent } from 'hpagent';

const proxy = 'http://user:pwd@host:8080';

const connection = new TikTokLiveConnection('@username', {
    webClientOptions: {
        agent: {
            http: new HttpProxyAgent({ proxy, keepAlive: true }),
            https: new HttpsProxyAgent({ proxy, keepAlive: true })
        }
    },
    wsClientOptions: {
        agent: new HttpsProxyAgent({ proxy, keepAlive: true })
    }
});

// Connect as usual
await connection.connect();

Authenticated Connection

To connect as a specific TikTok account, log into TikTok in your browser and copy two cookies: sessionid and tt-target-idc. Both are required. sessionid is your account's session token (keep it secret), and tt-target-idc is the datacenter region your account belongs to (for example useast1a for North America).

Pass them via the session.cookie bundle. To force the WebSocket itself to authenticate (so the server treats you as that account in chat), also set authenticateWs: true.

import { TikTokLiveConnection } from 'tiktok-live-connector';

const connection = new TikTokLiveConnection(
    'tv_asahi_news',
    {
        signApiKey: 'your-api-key',
        authenticateWs: true,
        session: {
            cookie: {
                type: 'cookie',
                value: {
                    sessionId: '<account_session_id>',
                    ttTargetIdc: '<account_target_idc>'
                }
            }
        }
    }
);

await connection.connect();
console.log('Connected to TikTok LIVE chat!');

You can also set the session after construction by calling setSessionBundle on the cookie jar:

await connection.webClient.cookieJar.setSessionBundle({
    type: 'cookie',
    value: {
        sessionId: '<account_session_id>',
        ttTargetIdc: '<account_target_idc>'
    }
});

Send Messages

sendMessage posts a chat message into the currently connected room. It requires a valid Euler Stream API key (see Signing Configuration) and an authenticated session bundle (cookies or OAuth token).

import { TikTokLiveConnection } from 'tiktok-live-connector';

const connection = new TikTokLiveConnection(
    'tv_asahi_news',
    {
        signApiKey: 'your-api-key',
        authenticateWs: true,
        session: {
            cookie: {
                type: 'cookie',
                value: {
                    sessionId: '<account_session_id>',
                    ttTargetIdc: '<account_target_idc>'
                }
            }
        }
    }
);

await connection.connect();
await connection.sendMessage('Hello world!');
console.log('Message sent!');
