TikTok Live Connector
Node.js library to receive live stream events
TikTok Live Connector is a Node.js library for receiving real-time TikTok LIVE events from TikTok’s internal Webcast push service. It can connect to a live stream by username and listen for events such as comments, gifts, member joins, follows, shares, questions, likes, subscriptions, viewer updates, and battles. The library does not require user credentials for basic live chat connection, which makes it useful for overlays, chat readers, bots, dashboards, alerts, and livestream interaction tools. It is a reverse-engineering project rather than an official TikTok production API, so developers should expect platform changes and occasional breakage. Recent development has focused on a more modular TypeScript architecture and expanded event schema support. It is best used for experiments, prototypes, creator tools, and non-critical realtime TikTok LIVE integrations. -
