: Use a simple fetch or a direct window.location.assign() for the download endpoint.
: Always sanitize the filesPath to prevent directory traversal attacks (where users could download system files). Download ligt rar
const { spawn } = require('child_process'); function downloadLightRar(res, filesPath) { // 'a' for add, '-m1' for fastest/lightest compression const rar = spawn('rar', ['a', '-m1', '-', ...filesPath]); res.setHeader('Content-Disposition', 'attachment; filename="package.rar"'); res.setHeader('Content-Type', 'application/x-rar-compressed'); rar.stdout.pipe(res); // Stream directly to the client rar.stderr.on('data', (data) => console.error(`Error: ${data}`)); } Use code with caution. Copied to clipboard B. Frontend UI Component : Use a simple fetch or a direct window
: The RAR compression algorithm is proprietary. Ensure your server has a licensed version of rar or consider using 7zip (which can create .7z or .zip files) as a more open-source "light" alternative. Copied to clipboard B
: Stream the file directly to the user to avoid high RAM usage from loading large files into memory. User Feedback : Provide real-time progress for downloads. 2. Implementation Steps A. Backend Architecture (Node.js/Python)
The user should see a "Download Light RAR" button that triggers the request and shows a loading state.
