​
Installation

npm i wukongimjssdk

​
Import

import WKSDK from "wukongimjssdk"
When using <script> tag import, you must add the wk prefix, for example wk.WKSDK.shared()

​
Basic Setup

​
Initialize SDK

// Get SDK instance
const sdk = WKSDK.shared();

// Configure SDK
sdk.config({
    addr: "ws://your-server.com:5200",  // WebSocket server address
    apiURL: "http://your-api-server.com", // API server address
    uploadURL: "http://your-upload-server.com", // File upload server address
    uid: "user123",                     // User ID
    token: "user-auth-token"            // User authentication token
});

​
TypeScript Support

If you’re using TypeScript, install the type definitions: 
npm install --save-dev @types/wukongimjssdk
Then import with types: 
import WKSDK, { WKMessage, WKChannel, WKChannelType } from "wukongimjssdk";

const sdk = WKSDK.shared();

​
Configuration Options

​

Framework Integration

​
React Integration

import React, { useEffect, useState } from 'react';
import WKSDK from 'wukongimjssdk';

function ChatApp() {
    const [sdk, setSdk] = useState(null);
    const [connected, setConnected] = useState(false);
    
    useEffect(() => {

            setConnected(status === 'connected');
        });
        
        // Listen for messages
        sdkInstance.chatManager.addMessageListener((message) => {
            console.log('New message:', message);
        });
        
        setSdk(sdkInstance);
        
        // Connect
        sdkInstance.connectionManager.connect();
        
        // Cleanup
        return () => {
            sdkInstance.connectionManager.disconnect();
        };
    }, []);
    
    return (
        <div>
            <h1>Chat App</h1>
            <p>Status: {connected ? 'Connected' : 'Disconnected'}</p>
        </div>
    );
}

​
Vue Integration

  beforeUnmount() {
    if (this.sdk) {
      this.sdk.connectionManager.disconnect();
    }
  },
  methods: {
    initSDK() {
      this.sdk = WKSDK.shared();
      
      // Configure SDK
      this.sdk.config({
        addr: "ws://your-server.com:5200",
        uid: "user123",

Angular Integration

import { Component, OnInit, OnDestroy } from '@angular/core';
import WKSDK from 'wukongimjssdk';

@Component({
  selector: 'app-chat',
  template: `
    <h1>Chat App</h1>
    <p>Status: {{ connected ? 'Connected' : 'Disconnected' }}</p>
  `
})
export class ChatComponent implements OnInit, OnDestroy {

  ngOnDestroy() {
    if (this.sdk) {
      this.sdk.connectionManager.disconnect();
    }
  }
  
  private initSDK() {
    this.sdk = WKSDK.shared();
    
    // Configure SDK
    this.sdk.config({
      addr: "ws://your-server.com:5200",
      uid: "user123",
      token: "user-auth-token"
    });
    
    // Listen for connection events
    this.sdk.connectionManager.addConnectStatusListener((status: string) => {

​
Environment Support

​
Browser Environment

// Check if running in browser
if (typeof window !== 'undefined') {
    // Browser-specific configuration
    sdk.config({
        enableLocalStorage: true,
        storagePrefix: "wk_browser_"
    });
}

​
Node.js Environment

// Check if running in Node.js
if (typeof process !== 'undefined' && process.versions && process.versions.node) {
    // Node.js-specific configuration
    sdk.config({
        enableLocalStorage: false, // Use file system instead
        storagePrefix: "wk_node_"
    });
}

​
Webpack Configuration

If you’re using Webpack, you might need to configure it for the SDK: 
// webpack.config.js
module.exports = {
  // ... other config
  resolve: {
    fallback: {
      "buffer": require.resolve("buffer"),
      "crypto": require.resolve("crypto-browserify"),
      "stream": require.resolve("stream-browserify")
    }
  },
  plugins: [
    new webpack.ProvidePlugin({
      Buffer: ['buffer', 'Buffer'],
    }),
  ]
};

​
Verification

Test your integration with this simple verification: 
// Test SDK initialization
const sdk = WKSDK.shared();
console.log('SDK instance:', sdk);

// Test configuration
sdk.config({
    addr: "ws://test-server.com:5200",
    uid: "test-user",
    token: "test-token"
});

// Test managers
console.log('Chat Manager:', sdk.chatManager);
console.log('Connection Manager:', sdk.connectionManager);
console.log('Channel Manager:', sdk.channelManager);

// Test connection (optional)
sdk.connectionManager.addConnectStatusListener((status) => {
    console.log('Connection status:', status);
});

// Uncomment to test actual connection
// sdk.connectionManager.connect();
