Real-time Data Streaming:\u003Cbr>WebSocket maintains a persistent connection between the server and client, making it ideal for real-time communication without reconnecting for every message.\u003C\u002Fp>\u003Cp>2. Handles Large Payloads Gracefully:\u003Cbr>With proper chunking and compression, WebSocket can reliably transmit large files or datasets.\u003C\u002Fp>\u003Cp>3. Bandwidth Efficiency:\u003Cbr>Compression significantly reduces the size of transferred data, optimizing network usage.\u003C\u002Fp>\u003Cp>4. Full-Duplex Communication:\u003Cbr>WebSocket supports simultaneous two-way communication, which is essential for interactive or collaborative applications.\u003C\u002Fp>\u003Cp> \u003C\u002Fp>\u003Ch2>🔸 Techniques for Sending Large Data via WebSocket\u003C\u002Fh2>\u003Cp> \u003C\u002Fp>\u003Ch3>✅ 1. Chunking (Splitting Large Data)\u003C\u002Fh3>\u003Cp>Chunking involves breaking up large data into smaller parts (chunks) before sending, which avoids overwhelming the WebSocket connection and ensures better control over transmission.\u003C\u002Fp>\u003Cp> \u003C\u002Fp>\u003Ch4>🔧 Sample Go Function for Chunking:\u003C\u002Fh4>\u003Cpre>\u003Ccode class=\"language-plaintext language-go\">func chunkData(data []byte, chunkSize int) [][]byte {\n    var chunks [][]byte\n    for i := 0; i < len(data); i += chunkSize {\n        end := i + chunkSize\n        if end > len(data) {\n            end = len(data)\n        }\n        chunks = append(chunks, data[i:end])\n    }\n    return chunks\n}\n\u003C\u002Fcode>\u003C\u002Fpre>\u003Cp>Each chunk can then be sent individually through the WebSocket connection.\u003C\u002Fp>\u003Cp> \u003C\u002Fp>\u003Ch3>✅ 2.
