Scramjet Proxy [portable]

Mass-harvesting text, images, or structured data from diverse web domains to feed large language models (LLMs) cleanly and efficiently.

Scramjet pushes thousands of target URLs into an asynchronous request stream.

Scramjet proxies are heavily utilized in edge computing. They allow developers to deploy lightweight "sequences" (small pieces of code) right where the data is generated—such as IoT gateways or localized cloud regions—preventing the need to send raw, bulky data back to a centralized data warehouse. Key Benefits of Using a Scramjet Proxy Low Latency Execution scramjet proxy

const DataStream = require("scramjet"); const axios = require("axios"); // A sample pool of rotating proxy servers const proxyPool = [ host: "192.168.1.50", port: 8080 , host: "192.168.1.51", port: 8080 , host: "192.168.1.52", port: 8080 ]; // Helper function to pick a random proxy function getRandomProxy() const index = Math.floor(Math.random() * proxyPool.length); return proxyPool[index]; // A stream of target URLs to scrape const urlSource = [ "https://example-target.com", "https://example-target.com", "https://example-target.com", ]; // Initialize Scramjet DataStream DataStream.fromArray(urlSource) .map(async (url) => const proxy = getRandomProxy(); try // Stream the HTTP request through the assigned proxy const response = await axios( method: "get", url: url, proxy: host: proxy.host, port: proxy.port , headers: "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)" , responseType: "stream" // Keeps the data in a stream state ); return url, stream: response.data ; catch (error) // Handle blocked proxies or dead links gracefully return url, error: error.message ; ) .filter(item => !item.error) // Filter out failed requests .map(async (item) => // Parse the incoming stream data on the fly let rawData = ""; for await (const chunk of item.stream) rawData += chunk; // Simulate extracting specific data point (e.g., Price) const priceMatch = rawData.match(/"price":\s*"([^"]+)"/); return url: item.url, price: priceMatch ? priceMatch[1] : "N/A", timestamp: new Date().toISOString() ; ) .assign( // Pipe the clean object directly to your data destination done: (data) => console.log("Successfully Scraped & Saved:", data) ) .catch(err => console.error("Stream Error:", err)); Use code with caution.

The reverse proxy (Nginx/Apache) is not configured to handle Upgrade headers. Fix: Ensure your Nginx config includes the proxy_set_header Upgrade and proxy_http_version 1.1 lines shown in Section 4.

Depending on your Scramjet Hub configuration, your application is now accessible via the proxy URL. Scramjet is designed for developers

: Running complex business logic, regex parsing, or cryptography inside the proxy layer consumes significant CPU cycles. It shifts the computing burden from backend databases to the network edge, requiring proper infrastructure scaling.

Scramjet is designed for developers, offering a clean API with TypeScript support and comprehensive documentation. Its flexible configuration allows users to tailor the proxy's behavior, including customizing codecs and setting specific flags, making it an excellent middleware component for open-source projects.
