Features

Feature 1: Streaming Responses (SSE)

Server-Sent Events (SSE) streaming for real-time data delivery. Perfect for AI chatbots, live updates, and progressive data loading.

Basic Streaming Example

const NetworkManager = require('ti.network.manager');

const stream = NetworkManager.createStreamRequest({
    url: 'https://api.example.com/ai/chat',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer YOUR_TOKEN'
    },
    body: JSON.stringify({
        message: 'Tell me about Titanium SDK',
        stream: true
    })
});

// Receive chunks as they arrive
stream.addEventListener('chunk', (e) => {
    console.log('Received chunk:', e.data);
    // Update UI progressively
    chatTextArea.value += e.data;
});

stream.addEventListener('complete', (e) => {
    console.log('Stream complete');
    console.log('Status:', e.statusCode);
});

stream.addEventListener('error', (e) => {
    console.error('Stream error:', e.error);
});

stream.start();

Advanced Streaming with Progress

const NetworkManager = require('ti.network.manager');

let chunkCount = 0;
let totalBytes = 0;

const stream = NetworkManager.createStreamRequest({
    url: 'https://api.example.com/data/stream',
    method: 'GET',
    priority: NetworkManager.PRIORITY_HIGH
});

stream.addEventListener('chunk', (e) => {
    chunkCount++;
    totalBytes += e.data.length;
    
    console.log('Chunk #' + chunkCount + ' (' + e.data.length + ' bytes)');
    console.log('Total received: ' + totalBytes + ' bytes');
    
    // Process chunk
    processData(e.data);
});

stream.addEventListener('complete', (e) => {
    console.log('Received ' + chunkCount + ' chunks');
    console.log('Total: ' + totalBytes + ' bytes');
});

stream.start();

// Cancel streaming if needed
setTimeout(() => {
    stream.cancel();
}, 30000); // Cancel after 30 seconds

Use Cases

1. AI Chatbots - Stream responses from AI services like OpenAI, Anthropic, or Google Gemini for real-time user feedback.
2. Live News Feeds - Receive breaking news updates as they happen without polling.
3. Stock Market Data - Stream real-time stock prices and trading information.
4. IoT Device Monitoring - Monitor sensor data from connected devices in real-time.
5. Live Event Coverage - Stream sports scores, election results, or event updates as they occur.

---

Feature 2: Certificate Pinning

Secure your API connections by validating server certificates against known public key hashes. Prevents man-in-the-middle attacks.

Configure Certificate Pinning

const NetworkManager = require('ti.network.manager');

// Set certificate pins for your domain
NetworkManager.setCertificatePinning(
    'api.example.com',
    [
        'sha256/AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=',
        'sha256/BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB='
    ]
);

// Now all requests to api.example.com will validate certificates
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/secure/data',
    method: 'GET'
});

request.addEventListener('complete', (e) => {
    if (e.success) {
        console.log('Secure connection validated!');
    }
});

request.addEventListener('error', (e) => {
    console.error('Certificate validation failed:', e.error);
});

request.send();

Multiple Domains

const NetworkManager = require('ti.network.manager');

// Pin multiple domains
NetworkManager.setCertificatePinning(
    'api.example.com',
    ['sha256/HASH1=', 'sha256/HASH2=']
);

NetworkManager.setCertificatePinning(
    'cdn.example.com',
    ['sha256/HASH3=', 'sha256/HASH4=']
);

// Requests to both domains will be pinned

How to Get Certificate Hashes

Use OpenSSL to extract the public key hash:

# Get certificate hash for your domain
openssl s_client -servername api.example.com -connect api.example.com:443 < /dev/null \
  | openssl x509 -pubkey -noout \
  | openssl pkey -pubin -outform der \
  | openssl dgst -sha256 -binary \
  | openssl enc -base64

Use Cases

1. Banking Apps - Ensure all financial transactions are secure and validated.
2. Healthcare Applications - Protect sensitive patient data with certificate validation.
3. E-commerce - Secure payment processing and user account information.
4. Enterprise Apps - Validate connections to corporate servers and prevent data breaches.
5. Government Applications - Meet compliance requirements for secure communications.

Feature 3: Request/Response Interceptors

Global middleware for modifying requests and responses. Perfect for adding authentication, logging, and error handling.

Request Interceptor

const NetworkManager = require('ti.network.manager');

// Add global request interceptor
NetworkManager.addRequestInterceptor((config) => {
    console.log('Intercepting request to:', config.url);
    
    // Add authentication token to all requests
    config.headers = config.headers || {};
    config.headers['Authorization'] = 'Bearer ' + getAuthToken();
    
    // Add timestamp
    config.headers['X-Request-Time'] = new Date().toISOString();
    
    // Log request
    console.log('Request:', config.method, config.url);
    
    return config;
});

// Now all requests will have the auth token
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/protected/data',
    method: 'GET'
});

request.send();

Response Interceptor

const NetworkManager = require('ti.network.manager');

// Add global response interceptor
NetworkManager.addResponseInterceptor((response) => {
    console.log('Response status:', response.statusCode);
    
    // Handle authentication errors globally
    if (response.statusCode === 401) {
        console.log('Unauthorized - refreshing token');
        refreshAuthToken();
    }
    
    // Handle rate limiting
    if (response.statusCode === 429) {
        console.log('Rate limited - backing off');
        showRateLimitWarning();
    }
    
    // Log response
    console.log('Response received from:', response.headers);
    
    return response;
});

Combined Example

const NetworkManager = require('ti.network.manager');

// Request interceptor - Add auth and logging
NetworkManager.addRequestInterceptor((config) => {
    config.headers = config.headers || {};
    config.headers['Authorization'] = 'Bearer ' + Ti.App.Properties.getString('authToken');
    config.headers['X-App-Version'] = Ti.App.version;
    config.headers['X-Device-ID'] = Ti.Platform.id;
    
    logAnalytics('api_request', {
        url: config.url,
        method: config.method
    });
    
    return config;
});

// Response interceptor - Handle errors globally
NetworkManager.addResponseInterceptor((response) => {
    // Handle token expiration
    if (response.statusCode === 401) {
        Ti.App.fireEvent('auth:expired');
        redirectToLogin();
    }
    
    // Handle server errors
    if (response.statusCode >= 500) {
        showErrorNotification('Server error. Please try again.');
    }
    
    // Log response time
    if (response.headers['X-Response-Time']) {
        logAnalytics('api_response_time', {
            time: response.headers['X-Response-Time']
        });
    }
    
    return response;
});

Use Cases

1. Authentication Management - Automatically add and refresh authentication tokens for all requests.
2. Analytics Tracking - Log all API calls for monitoring and debugging.
3. Error Handling - Implement global error handling and user notifications.
4. API Versioning - Add version headers to all requests automatically.
5. Request Logging - Debug production issues by logging all network activity.

const NetworkManager = require('ti.network.manager');

const request = NetworkManager.createRequest({
    url: 'https://api.example.com/data',
    method: 'GET',
    retry: {
        max: 5,                    // Maximum 5 retry attempts
        backoff: NetworkManager.RETRY_BACKOFF_EXPONENTIAL,
        baseDelay: 1.0,           // Start with 1 second delay
        retryOn: [500, 502, 503, 504]  // Retry on server errors
    }
});

request.addEventListener('error', (e) => {
    if (e.willRetry) {
        console.log('Request failed, will retry automatically');
    } else {
        console.log('Request failed after all retries');
    }
});

request.addEventListener('complete', (e) => {
    console.log('Request succeeded!');
});

request.send();

Exponential Backoff

const NetworkManager = require('ti.network.manager');

// Exponential backoff: 1s, 2s, 4s, 8s, 16s
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/upload',
    method: 'POST',
    body: JSON.stringify({ data: 'important' }),
    retry: {
        max: 5,
        backoff: NetworkManager.RETRY_BACKOFF_EXPONENTIAL,
        baseDelay: 1.0,
        retryOn: [408, 500, 502, 503, 504]  // Timeout and server errors
    }
});

request.send();

Linear Backoff

const NetworkManager = require('ti.network.manager');

// Linear backoff: 2s, 4s, 6s, 8s, 10s
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/process',
    method: 'POST',
    retry: {
        max: 5,
        backoff: NetworkManager.RETRY_BACKOFF_LINEAR,
        baseDelay: 2.0,
        retryOn: [429, 500, 503]  // Rate limiting and server errors
    }
});

request.addEventListener('error', (e) => {
    console.log('Error:', e.error);
    console.log('Will retry:', e.willRetry);
});

request.send();

Custom Retry Conditions

const NetworkManager = require('ti.network.manager');

const request = NetworkManager.createRequest({
    url: 'https://api.example.com/critical',
    method: 'POST',
    retry: {
        max: 10,  // More retries for critical operations
        backoff: NetworkManager.RETRY_BACKOFF_EXPONENTIAL,
        baseDelay: 0.5,  // Start with shorter delay
        retryOn: [408, 429, 500, 502, 503, 504, 509]  // Extensive retry conditions
    }
});

request.send();

Use Cases

1. Unstable Networks - Handle poor connectivity in mobile apps gracefully without user intervention.

Feature 5: Advanced Caching

Intelligent HTTP caching with multiple strategies and TTL support. Reduce API calls and improve performance.

Cache-First Strategy

const NetworkManager = require('ti.network.manager');

// Use cached data if available, otherwise fetch from network
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/movies',
    method: 'GET',
    cache: {
        policy: NetworkManager.CACHE_POLICY_CACHE_FIRST,
        ttl: 3600  // Cache for 1 hour (in seconds)
    }
});

request.addEventListener('complete', (e) => {
    if (e.cached) {
        console.log('Data loaded from cache');
    } else {
        console.log('Data fetched from network');
    }
    
    const movies = JSON.parse(e.body);
    displayMovies(movies);
});

request.send();

Network-First Strategy

const NetworkManager = require('ti.network.manager');

// Try network first, fallback to cache if network fails
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/news',
    method: 'GET',
    cache: {
        policy: NetworkManager.CACHE_POLICY_NETWORK_FIRST,
        ttl: 1800  // Cache for 30 minutes
    }
});

request.send();

Network-Only (No Cache)

const NetworkManager = require('ti.network.manager');

// Always fetch from network, never use cache
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/realtime-data',
    method: 'GET',
    cache: {
        policy: NetworkManager.CACHE_POLICY_NETWORK_ONLY
    }
});

request.send();

Clear Cache

const NetworkManager = require('ti.network.manager');

// Clear cache for specific domain
NetworkManager.clearCache('api.example.com');

// Or clear all cache
NetworkManager.clearCache();

Complete Caching Example

const NetworkManager = require('ti.network.manager');

// Product catalog with 1-hour cache
const productsRequest = NetworkManager.createRequest({
    url: 'https://api.example.com/products',
    method: 'GET',
    cache: {
        policy: NetworkManager.CACHE_POLICY_CACHE_FIRST,
        ttl: 3600
    }
});

productsRequest.addEventListener('complete', (e) => {
    const products = JSON.parse(e.body);
    
    if (e.cached) {
        console.log('Loaded ' + products.length + ' products from cache');
        showOfflineIndicator();
    } else {
        console.log('Fetched ' + products.length + ' products from network');
    }
    
    renderProductList(products);
});

productsRequest.send();

// Clear cache when user explicitly refreshes
refreshButton.addEventListener('click', () => {
    NetworkManager.clearCache('api.example.com');
    productsRequest.send();
});

Use Cases

1. Product Catalogs - Cache product listings to reduce API calls and improve browsing speed.
2. News Articles - Cache articles for offline reading and faster load times.
3. User Profiles - Cache profile data to reduce server load and improve responsiveness.
4. Static Content - Cache configuration, translations, and other static data.
5. Offline Support - Provide functionality even when network is unavailable.

Feature 7: Request Prioritization

Control which requests get network resources first. Ensure critical operations complete quickly.

Priority Levels

const NetworkManager = require('ti.network.manager');

// High priority - Critical user action
const loginRequest = NetworkManager.createRequest({
    url: 'https://api.example.com/auth/login',
    method: 'POST',
    body: JSON.stringify({
        email: email,
        password: password
    }),
    priority: NetworkManager.PRIORITY_HIGH
});

// Normal priority - Standard data fetch
const dataRequest = NetworkManager.createRequest({
    url: 'https://api.example.com/data',
    method: 'GET',
    priority: NetworkManager.PRIORITY_NORMAL
});

// Low priority - Background prefetch
const prefetchRequest = NetworkManager.createRequest({
    url: 'https://api.example.com/prefetch',
    method: 'GET',
    priority: NetworkManager.PRIORITY_LOW
});

Practical Example

const NetworkManager = require('ti.network.manager');

// High priority: User's current action
const submitOrder = NetworkManager.createRequest({
    url: 'https://api.example.com/orders',
    method: 'POST',
    body: JSON.stringify(orderData),
    priority: NetworkManager.PRIORITY_HIGH
});

submitOrder.addEventListener('complete', (e) => {
    if (e.success) {
        showOrderConfirmation();
    }
});

submitOrder.send();

// Low priority: Prefetch next page data
const prefetchNextPage = NetworkManager.createRequest({
    url: 'https://api.example.com/products?page=2',
    method: 'GET',
    priority: NetworkManager.PRIORITY_LOW
});

prefetchNextPage.send();

Dynamic Priority

const NetworkManager = require('ti.network.manager');

function fetchUserData(isUrgent) {
    const request = NetworkManager.createRequest({
        url: 'https://api.example.com/user/profile',
        method: 'GET',
        priority: isUrgent 
            ? NetworkManager.PRIORITY_HIGH 
            : NetworkManager.PRIORITY_NORMAL
    });
    
    request.send();
}

// User clicked profile button - high priority
fetchUserData(true);

// Background refresh - normal priority
setInterval(() => {
    fetchUserData(false);
}, 300000); // Every 5 minutes

Use Cases

1. Payment Processing - Prioritize checkout and payment requests over other operations.
2. Search Results - Give high priority to search queries for immediate user feedback.
3. Image Loading - Load visible images with high priority, prefetch others with low priority.
4. Chat Messages - Prioritize sending and receiving messages over loading history.
5. Analytics - Send analytics data with low priority to not affect user experience.

Feature 9: HTTP/2 & HTTP/3 Support

Automatic support for modern HTTP protocols. Provides better performance through multiplexing and header compression.

HTTP/2 and HTTP/3 support is automatic and requires no special configuration. The module uses URLSession which automatically negotiates the best protocol with the server.

Automatic Protocol Negotiation

const NetworkManager = require('ti.network.manager');

// This request will automatically use HTTP/2 or HTTP/3 if the server supports it
const request = NetworkManager.createRequest({
    url: 'https://api.example.com/data',
    method: 'GET'
});

request.addEventListener('complete', (e) => {
    console.log('Request completed');
    // HTTP/2 or HTTP/3 was used automatically if available
});

request.send();

Benefits Demonstration

const NetworkManager = require('ti.network.manager');

// Make multiple parallel requests - HTTP/2 multiplexing makes this efficient
const requests = [
    'https://api.example.com/users',
    'https://api.example.com/products',
    'https://api.example.com/orders',
    'https://api.example.com/analytics'
];

requests.forEach(url => {
    const request = NetworkManager.createRequest({
        url: url,
        method: 'GET'
    });
    
    request.addEventListener('complete', (e) => {
        console.log('Loaded:', url);
        // With HTTP/2, all requests share the same connection
        // Much faster than HTTP/1.1's connection per request
    });
    
    request.send();
});

Use Cases

1. Parallel Data Loading - Load multiple resources simultaneously with efficient connection reuse.
2. Real-time Applications - Reduced latency for time-sensitive operations.
3. Mobile Performance - Better battery life and network efficiency.
4. Large API Responses - Improved performance for data-heavy applications.
5. Future-Proofing - Automatically benefit from protocol improvements.
