Overview

The Zoom Video SDK UI Toolkit is a pre-built video UI library that renders complete video conferencing experiences with minimal code. Unlike the raw Video SDK, the UI Toolkit provides:

• ✅ Ready-to-use UI - Professional video interface out of the box
• ✅ Zero UI code - No need to build video layouts, controls, or participant management
• ✅ Framework agnostic - Works with React, Vue, Angular, Next.js, vanilla JS
• ✅ Highly customizable - Choose which features to enable, customize themes
• ✅ Built-in features - Chat, screen share, settings, virtual backgrounds included

When to use UI Toolkit:

• You want a complete video solution quickly
• You need Zoom-like UI consistency
• You don't want to build custom video UI
• You need standard features (chat, share, participants)

When to use raw Video SDK instead:

• You need complete custom UI control
• You're building a non-standard video experience
• You need access to raw video/audio data
• You want to build your own rendering pipeline

Installation

npm install @zoom/videosdk-zoom-ui-toolkit jsrsasign
npm install -D @types/jsrsasign

Note: React support depends on the UI Toolkit version. Check the package peer dependencies for your installed version (React 18 is commonly required).

Quick Start

Basic Usage (Vanilla JS)

import uitoolkit from "@zoom/videosdk-zoom-ui-toolkit";
import "@zoom/videosdk-ui-toolkit/dist/videosdk-zoom-ui-toolkit.css";

const container = document.getElementById("sessionContainer");

const config = {
  videoSDKJWT: "your_jwt_token",
  sessionName: "my-session",
  userName: "John Doe",
  sessionPasscode: "",
  features: ["video", "audio", "share", "chat", "users", "settings"],
};

uitoolkit.joinSession(container, config);

uitoolkit.onSessionJoined(() => {
  console.log("Session joined");
});

uitoolkit.onSessionClosed(() => {
  console.log("Session closed");
});

Next.js / React Integration

'use client';

import { useEffect, useRef } from 'react';

export default function VideoSession({ jwt, sessionName, userName }) {
  const containerRef = useRef<HTMLDivElement>(null);
  const uitoolkitRef = useRef<any>(null);

  useEffect(() => {
    let isMounted = true;

    const init = async () => {
      const uitoolkitModule = await import('@zoom/videosdk-zoom-ui-toolkit');
      const uitoolkit = uitoolkitModule.default;
      uitoolkitRef.current = uitoolkit;

      // If TypeScript complains about CSS imports, configure your app to allow them
      // (for example via a global `declare module \"*.css\";`), or import the CSS from
      // a global entrypoint (Next.js layout/_app) instead of inlining here.
      await import('@zoom/videosdk-ui-toolkit/dist/videosdk-zoom-ui-toolkit.css');

      if (!isMounted || !containerRef.current) return;

      const config: any = {
        videoSDKJWT: jwt,
        sessionName: sessionName,
        userName: userName,
        sessionPasscode: '',
        features: ['video', 'audio', 'share', 'chat', 'users', 'settings'],
      };

      uitoolkit.joinSession(containerRef.current, config);
      uitoolkit.onSessionJoined(() => console.log('Joined'));
      uitoolkit.onSessionClosed(() => console.log('Closed'));
    };

    init();

    return () => {
      isMounted = false;
      if (uitoolkitRef.current && containerRef.current) {
        try {
          uitoolkitRef.current.closeSession(containerRef.current);
        } catch (e) {}
      }
    };
  }, [jwt, sessionName, userName]);

  return <div ref={containerRef} style={{ width: '100%', height: '100vh' }} />;
}

Troubleshooting

• troubleshooting/common-issues.md - CSS, SSR, JWT/session join, customization limits

JWT Token Generation (Server-Side)

Required: Generate JWT tokens on your server, never expose SDK secret client-side.

Node.js / Next.js API Route

import { NextRequest, NextResponse } from 'next/server';
import { KJUR } from 'jsrsasign';

const ZOOM_VIDEO_SDK_KEY = process.env.ZOOM_VIDEO_SDK_KEY;
const ZOOM_VIDEO_SDK_SECRET = process.env.ZOOM_VIDEO_SDK_SECRET;

export async function POST(request: NextRequest) {
  const { sessionName, role, userName } = await request.json();

  if (!sessionName || role === undefined) {
    return NextResponse.json({ error: 'Missing params' }, { status: 400 });
  }

  const iat = Math.floor(Date.now() / 1000);
  const exp = iat + 60 * 60 * 2; // 2 hours

  const oHeader = { alg: 'HS256', typ: 'JWT' };
  const oPayload = {
    app_key: ZOOM_VIDEO_SDK_KEY,
    role_type: role, // 0 = participant, 1 = host
    tpc: sessionName,
    version: 1,
    iat,
    exp,
    user_identity: userName || 'User',
  };

  const signature = KJUR.jws.JWS.sign(
    'HS256',
    JSON.stringify(oHeader),
    JSON.stringify(oPayload),
    ZOOM_VIDEO_SDK_SECRET
  );

  return NextResponse.json({ signature });
}

JWT Payload Fields

Field	Required	Description
app_key	Yes	Your Video SDK Key
role_type	Yes	0 = participant, 1 = host
tpc	Yes	Session/topic name
version	Yes	Always 1
iat	Yes	Issued at (Unix timestamp)
exp	Yes	Expiration (Unix timestamp)
user_identity	No	User identifier

fetch('/your-app-path/api/token', { ... })

Prerequisites

1. Zoom Video SDK credentials from Zoom Marketplace
2. React version compatible with your installed UI Toolkit package (check peer deps; React 18 is common)
3. Server-side JWT generation (never expose SDK secret)
4. Modern browser with WebRTC support

Browser Support

Browser	Version
Chrome	78+
Firefox	76+
Safari	14.1+
Edge	79+

Common Issues

Issue	Solution
peer react@"^18.0.0" error	Use the React version required by the installed UI Toolkit package (check peer deps; React 18 is common)
CSS import TypeScript error	Configure TS/CSS handling (prefer a global *.css module declaration); avoid @ts-ignore except in throwaway demos
Config type error	Type config as any
API returns HTML not JSON	Check basePath in fetch URL

📋 Quick Reference Card

Minimal Working Example

import uitoolkit from "@zoom/videosdk-zoom-ui-toolkit";
import "@zoom/videosdk-ui-toolkit/dist/videosdk-zoom-ui-toolkit.css";

const config = {
  videoSDKJWT: "YOUR_JWT",
  sessionName: "test-session",
  userName: "User",
  featuresOptions: {
    video: { enable: true },
    audio: { enable: true }
  }
};

uitoolkit.joinSession(document.getElementById("container"), config);
uitoolkit.onSessionJoined(() => console.log("Joined"));
uitoolkit.onSessionClosed(() => uitoolkit.destroy());

Must-Remember Rules

1. ✅ Always generate JWT server-side
2. ✅ Always call destroy() on cleanup
3. ✅ Always use React 18 (not 17/19)
4. ✅ Always import CSS file
5. ❌ Never expose SDK secret client-side
6. ❌ Never skip onSessionClosed cleanup
7. ❌ Never call components before joinSession
