Why developers use TRTC Web SDK

• Built on Tencent RTC’s globally proven real-time network: backed by Tencent’s long-standing expertise in audio/video and network technology, with below 300 ms end-to-end latency for calling scenarios, below 1000 ms audience latency for live streaming, and over 99.99% service uptime
• Low-latency, production-ready communication: optimized for video calls, voice calls, interactive live streaming, conferencing, and other scenarios that need fast join times, stable connectivity, and smooth interaction
• Cross-browser support with cross-platform interoperability: works on major modern desktop and mobile browsers and fits naturally into product ecosystems that also span Android, iOS, Flutter, Electron, and React Native
• Flexible integration model: supports vanilla JavaScript, Vue, and any web framework, so teams can prototype quickly or integrate into existing frontend architectures
• Ready for meetings, live streaming, and richer RTC workflows: beyond calling, it supports screen sharing, host/audience live streaming, cross-room co-hosting, and other common real-time interaction patterns
• Strong diagnostics for devices, environments, and challenging networks: includes browser capability checks, permission and device detection, network quality evaluation, device hot-plug handling, and debug workflows
• Advanced media and live orchestration: custom capture/rendering, multi-user video with small stream, cloud mixing and CDN streaming, watermarking, and video mixer workflows for more complex media pipelines
• Plugin-based enhancement and AI capabilities: audio mixer, beauty/basic beauty, virtual background, AI noise reduction, voice changer, face detection, small-stream auto switching, and real-time transcription/translation
• Clear path from core SDK to faster delivery: build deeply customized RTC experiences with the SDK, or move faster with Call, Conference, Live, Chat, and other UIKit-based solutions in the Tencent RTC ecosystem

Quick Start

Install

npm install trtc-sdk-v5 --save

or

yarn add trtc-sdk-v5

You can also download trtc.js manually and include it in your project.

Basic Usage

import TRTC from 'trtc-sdk-v5';

const trtc = TRTC.create();

await trtc.enterRoom({
  sdkAppId,
  userId,
  userSig,
  strRoomId: 'room_123',
});

await trtc.startLocalVideo({
  view: document.getElementById('local-video'),
});
