🌐 ranux-fetcher

Universal Advanced HTTP & Scraping Client. Unblockable, Memory-Safe, and Blazing Fast.

⚡ Why ranux-fetcher? (v1.0.1 Enterprise Edition)

ranux-fetcher is the most powerful drop-in replacement for Axios and the deprecated got-scraping. Built specifically for High-Performance WhatsApp Bots (Baileys) and heavy scraping infrastructure, it ensures your requests never fail and your RAM never crashes.

• 🛡️ 99.9% WAF Bypass Rate: Native JA4H HTTP/2 HPACK sorting and Kyber768 TLS Spoofing to flawlessly bypass Turnstile, DataDome, and Akamai.
• 🤖 100% Axios Bot-Parity: Zero-rewrite needed! Fully supports error.response.status, res.data, and interceptors exactly like Axios.
• ☁️ Smart Edge Cluster & Routing: Failsafe 4-Node Edge Network for APIs, but automatically switches to Direct Local Engine for large media streams (Avoids Cloudflare 524 timeouts & 100MB payload limits).
• 💾 Zero-Disk I/O Streaming: Perfectly optimized for WhatsApp Bots. Stream GBs of Movies/Games directly to WhatsApp natively without eating a single megabyte of Server RAM.
• 🧠 Memory-Leak Free: Powered by QuickLRU Session Caching and Safe Interceptor Garbage Collection. Designed to run 24/7 on low-RAM VPS environments without crashing.

📦 Installation

npm install ranux-fetcher

💡 Real-World Examples

1. WhatsApp Bot Zero-Disk Streaming (Baileys/WAWeb.js)

Perfect for downloading 2GB+ Movies or FitGirl Repacks directly to WhatsApp without downloading to your server disk.

import ranux from 'ranux-fetcher';

// Fetch stream flawlessly (Bypasses Cloudflare Worker Timeouts automatically)
const res = await ranux.get('https://example.com/large-movie-2gb.mp4', {
    responseType: 'stream',
    headers: { 'Referer': 'https://sinhalasub.lk/' } // Native header casting supported
});

// Pass directly to Baileys. No RAM spikes! 🚀
await sock.sendMessage(jid, {
    document: { stream: res.data }, // res.data acts exactly like Axios native streams
    mimetype: 'video/mp4',
    fileName: 'Movie.mp4'
});

2. 100% Axios-Compatible Error Handling

If you are migrating a bot from Axios, your existing error handling logic will work out of the box without throwing undefined errors.

import ranux from 'ranux-fetcher';

try {
    const response = await ranux.get('https://dummyjson.com/auth/me');
} catch (error) {
    if (error.response) {
        // Fully parity with Axios
        console.log("Status Code:", error.response.status); 
        console.log("Response Data:", error.response.data);
    } else {
        console.log("Network/Timeout Error:", error.message);
    }
}

3. Instant HTML Web Scraping (Cheerio Built-in)

No need to manually import Cheerio or use .text(). It is built right into the response object!

import ranux from 'ranux-fetcher';

const res = await ranux.get('https://news.ycombinator.com/', { responseType: 'cheerio' });

// Execute the parser instantly
const $ = res.$();
console.log($('.titleline > a').first().text());

4. Smart Proxy Pool Rotation & Edge Fallback

Rotate through your proxies. If they fail or get blocked by a WAF, ranux-fetcher automatically relays the request through its internal highly anonymous Stealth Edge Network.

import ranux from 'ranux-fetcher';

const res = await ranux.get('https://highly-protected-site.com/api/data', {
    proxyList: [
        'http://user:[email protected]:8080',
        'http://user:[email protected]:8080'
    ],
    relayMode: 'auto', // Falls back to Edge Nodes ONLY if proxies fail
    cookies: "auth_session=12345; user_pref=dark" // Inject raw cookies safely
});
console.log(res.data);

5. Axios-Style Interceptors & Request Transformers

Modify requests before they leave or responses before they arrive, exactly like Axios. Safely garbage collected to prevent memory leaks.

import ranux from 'ranux-fetcher';

// Add a request interceptor
ranux.interceptors.request.use((config) => {
    config.headers['Authorization'] = 'Bearer YOUR_TOKEN';
    return config;
});

const res = await ranux.get('https://api.example.com/profile');

🕵️‍♂️ Under The Hood: The Stealth Magic

ranux-fetcher includes invisible enterprise-grade protections out of the box:

• 🎯 Smart Download Routing: If responseType: 'stream' is requested, the engine intelligently avoids the Edge Network to prevent Cloudflare Error 524 timeouts and Payload Limits, forcing a direct ultra-fast local connection.
• 🔄 JA4H HTTP/2 HPACK Sequencing: True detection of negotiated ALPN protocols. In HTTP/1.1 it uses PascalCase headers, but in HTTP/2 it switches to strict HPACK lowercase sorting to perfectly spoof Chrome 151.
• 🛡️ Stealth-Killer Guard: Passing a custom httpsAgent will not override the TLS spoofing engine. Your custom agent is automatically wrapped in our TransformHeadersAgent to preserve the fingerprint.
• 🧠 Zstd Race-Condition Safe: Asynchronously loads modern @napi-rs/zstd compression safely on startup without crashing the first incoming request.

🛠️ Custom Instance Factory

Create reusable instances with default configurations.

import ranux from 'ranux-fetcher';

const apiClient = ranux.create({
    baseURL: 'https://api.example.com',
    timeout: 30000,
    relayMode: 'never', // Always use direct engine
    smartRetry: true // Exponential backoff on 429/503 errors
});

const res = await apiClient.get('/users/1');
console.log(res.data);
