WebSockets & Real-Time Communication

How should WebSocket compression be implemented?

const ws = new WebSocket('ws://example.com', {
    perMessageDeflate: {
        zlibDeflateOptions: {
            level: 6,
            memLevel: 8
        },
        zlibInflateOptions: {
            chunkSize: 16 * 1024
        },
        clientNoContextTakeover: true,
        serverNoContextTakeover: true,
        threshold: 1024
    }
});

Compress all messages manually
Never use compression
Use per-message compression with proper configuration
WebSocket compression should be implemented considering: 1) Per-message compression using the built-in extensions, 2) Compression level based on data type and size, 3) Memory usage considerations, 4) CPU overhead balancing, 5) Threshold settings for small messages, 6) Context takeover settings for efficiency, 7) Compression dictionary optimization, 8) Monitoring compression ratios, 9) Fallback mechanisms when compression fails, 10) Performance impact analysis.
Always use maximum compression
