Node.js library to receive live stream chat events like comments and gifts in realtime from TikTok LIVE.

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. The 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, Viewers, Follows, Shares, Questions, Likes and Battles can be tracked. You can also send automatic messages into the chat by providing your Session ID.

• Go rewrite: GoTikTokLive by @Davincible

NOTE: This is not an official API. It's a reverse engineering project.

NOTE: This JavaScript library is intended for use in Node.js environments. If you want to process or display the data in the browser (client-side), you need to transfer the data from the Node.js environment to the browser. A good approach for this is to use Socket.IO or a different low-latency communication framework. A complete example project can be found here: TikTok-Chat-Reader

Getting started

1. Install the package via NPM

npm i tiktok-live-connector

2. Create your first chat connection

const { WebcastPushConnection } = require('tiktok-live-connector');

// Username of someone who is currently live
let tiktokUsername = "officialgeilegisela";

// Create a new wrapper object and pass the username
let tiktokChatConnection = new WebcastPushConnection(tiktokUsername);

// Connect to the chat (await can be used as well)
tiktokChatConnection.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)
tiktokChatConnection.on('chat', data => {
    console.log(`${data.uniqueId} (userId:${data.userId}) writes: ${data.comment}`);
})

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

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

Params and options

To create a new WebcastPushConnection object the following parameters are required.

WebcastPushConnection(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 => officialgeilegisela
options	No	Here you can set the following optional connection properties. If you do not specify a value, the default value will be used. processInitialData (default: true) Define if you want to process the initital data which includes old messages of the last seconds. fetchRoomInfoOnConnect (default: true) Define if you want to fetch all room information on connect(). If this option is enabled, the connection to offline rooms will be prevented. If enabled, the connect result contains the room info via the roomInfo attribute. You can also manually retrieve the room info (even in an unconnected state) using the getRoomInfo() function. enableExtendedGiftInfo (default: false) Define if you want to receive extended information about gifts like gift name, cost and images. This information will be provided at the gift event. enableWebsocketUpgrade (default: true) Define if you want to use a WebSocket connection instead of request polling if TikTok offers it. requestPollingIntervalMs (default: 1000) Request polling interval if WebSocket is not used. sessionId (default: null) Here you can specify the current Session ID of your TikTok account (sessionid cookie value) if you want to send automated chat messages via the sendMessage() function. See Example clientParams (default: {}) Custom client params for Webcast API. requestHeaders (default: {}) Custom request headers passed to axios. websocketHeaders (default: {}) Custom websocket headers passed to websocket.client. requestOptions (default: {}) Custom request options passed to axios. Here you can specify an httpsAgent to use a proxy and a timeout value. See Example. websocketOptions (default: {}) Custom websocket options passed to websocket.client. Here you can specify an agent to use a proxy and a timeout value. See Example.

Example Options:

let tiktokChatConnection = new WebcastPushConnection(tiktokUsername, {
    processInitialData: false,
    enableExtendedGiftInfo: true,
    enableWebsocketUpgrade: true,
    requestPollingIntervalMs: 2000,
    clientParams: {
        "app_language": "en-US",
        "device_platform": "web"
    },
    requestHeaders: {
        "headerName": "headerValue"
    },
    websocketHeaders: {
        "headerName": "headerValue"
    },
    requestOptions: {
        timeout: 10000
    },
    websocketOptions: {
        timeout: 10000
    }
});

Methods

A WebcastPushConnection object contains the following methods.

Method Name	Description
connect	Connects to the live stream chat. Returns a Promise which will be resolved when the connection is successfully established.
disconnect	Disconnects the connection.
getState	Gets the current connection state including the cached room info (see below).
getRoomInfo	Gets the current room info from TikTok API including streamer info, room status and statistics. Returns a Promise which will be resolved when the API request is done. Note: You can call this function even if you're not connected. Example
getAvailableGifts	Gets a list of all available gifts including gift name, image url, diamont cost and a lot of other information. Returns a Promise that will be resolved when all available gifts has been retrieved from the API. Note: You can call this function even if you're not connected. Example
sendMessage (text, [sessionId])	Sends a chat message into the current live room using the provided session cookie (specified in the constructor options or via the second function parameter). Returns a Promise that will be resolved when the chat message has been submitted to the API. WARNING: Use of this function is at your own risk. Spamming messages can lead to the suspension of your TikTok account. Be careful! Example

Events

A WebcastPushConnection object has the following events which can be handled via .on(eventName, eventHandler)

Control Events:

• connected
• disconnected
• streamEnd
• rawData
• websocketConnected
• error

Message Events:

• member
• chat
• gift
• roomUser
• like
• social
• questionNew
• linkMicBattle
• linkMicArmies
• liveIntro

Control Events

connected

Triggered when the connection gets successfully established.

tiktokChatConnection.on('connected', state => {
    console.log('Hurray! Connected!', state);
})

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.

tiktokChatConnection.on('disconnected', () => {
    console.log('Disconnected :(');
})

streamEnd

Triggered when the live stream gets terminated by the host. Will also trigger the disconnected event.

tiktokChatConnection.on('streamEnd', () => {
    console.log('Stream ended');
})

rawData

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

tiktokChatConnection.on('rawData', (messageTypeName, binary) => {
    console.log(messageTypeName, binary);
})

websocketConnected

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

tiktokChatConnection.on('websocketConnected', websocketClient => {
    console.log("Websocket:", websocketClient.connection);
})

error

General error event. You should handle this.

tiktokChatConnection.on('error', err => {
    console.error('Error!', err);
})

Message Events

member

Triggered every time a new viewer joins the live stream.

tiktokChatConnection.on('member', data => {
    console.log(`${data.uniqueId} joins the stream!`);
})

Data structure:

{
  userId: '6776663624629974021',
  uniqueId: 'zerodytester',
  nickname: 'Zerody One',
  profilePictureUrl: 'https://p16-sign-va.tiktokcdn.com/...',
  followRole: 1, // 0 = none; 1 = follower; 2 = friends
  userBadges: [] // e.g. Moderator badge
}

chat

Triggered every time a new chat comment arrives.

tiktokChatConnection.on('chat', data => {
    console.log(`${data.uniqueId} writes: ${data.comment}`);
})

Data structure:

{
    comment: 'how are you?',
    userId: '6776663624629974121',
    uniqueId: 'zerodytester',
    nickname: 'Zerody One',
    profilePictureUrl: 'https://p16-sign-va.tiktokcdn.com/...',
    followRole: 2, // 0 = none; 1 = follower; 2 = friends
    userBadges: [
        {
            type: 'pm_mt_moderator_im', 
            name: 'Moderator'
        }
    ]
}

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:

tiktokChatConnection.on('gift', data => {
    if (data.giftType === 1 && !data.repeatEnd) {
        // Streak in progress => show only temporary
        console.log(`${data.uniqueId} is sending gift ${data.giftName} x${data.repeatCount}`);
    } else {
        // Streak ended or non-streakable gift => process the gift with final repeat_count
        console.log(`${data.uniqueId} has sent gift ${data.giftName} x${data.repeatCount}`);
    }
})

Data structure:

{
  // Sender Details
  userId: '6976651226482787334',
  uniqueId: 'zerodytester',
  nickname: 'Zerody One',
  followRole: 0,
  userBadges: [],
  profilePictureUrl: 'https://p16-sign.tiktokcdn-us.com/...',

        }
    ]
}

liveIntro

Triggered when a live intro message appears.

tiktokChatConnection.on('liveIntro', (msg) => {
    console.log(msg);
})

Examples

Retrieve Room Info

let tiktokChatConnection = new WebcastPushConnection('@username');

tiktokChatConnection.getRoomInfo().then(roomInfo => {
    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

let tiktokChatConnection = new WebcastPushConnection('@username');

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

Send Chat Messages

You can send chat messages via the sendMessage() function to automatically respond to chat commands for example. For this you need to provide your Session ID.

To get the Session ID from your account, open TikTok in your web browser and make sure you are logged in, then press F12 to open the developer tools. Switch to the Application tab and select Cookies on the left side. Then take the value of the cookie with the name sessionid.

WARNING: Use of this function is at your own risk. Spamming messages can lead to the suspension of your TikTok account. Be careful!

let tiktokChatConnection = new WebcastPushConnection('@username', {
    sessionId: 'f7fbba3a57e48dd1ecd0b7b72cb27e6f' // Replace this with the Session ID of your TikTok account
});

tiktokChatConnection.connect().catch(err => console.log(err));

tiktokChatConnection.on('chat', data => {
    if (data.comment.toLowerCase() === '!dice') {
        let diceResult = Math.ceil(Math.random() * 6);
        tiktokChatConnection.sendMessage(`@${data.uniqueId} you rolled a ${diceResult}`).catch(err => console.error(err));
    }
})

Connect via Proxy

proxy-agent supports http, https, socks4 and socks5 proxies:

npm i proxy-agent

You can specify if you want to use a proxy for https requests, websockets or both:

const { WebcastPushConnection } = require('tiktok-live-connector');
const ProxyAgent = require('proxy-agent');

let tiktokChatConnection = new WebcastPushConnection('@username', {
    requestOptions: {
        httpsAgent: new ProxyAgent('https://username:password@host:port'),
        timeout: 10000 // 10 seconds
    },
    websocketOptions: {
        agent: new ProxyAgent('https://username:password@host:port'),
        timeout: 10000 // 10 seconds
    }
});

// Connect as usual
