WebSocket compression is essential for reducing bandwidth and improving responsiveness, especially when transmitting repetitive data like JSON payloads. The permessage-deflate extension compresses every WebSocket frame on the fly — but the speed of that compression directly impacts your application's throughput. Starting with sgcWebSockets 20...

OAuth 2.0 access tokens are the keys to your API kingdom — and if someone steals one, they can use it from anywhere. DPoP (Demonstrating Proof of Possession), defined in RFC 9449, solves this by cryptographically binding tokens to the client that requested them. Even if a token is intercepted, it becomes useless without the client's private k...

Security is no longer optional. Every WebSocket server exposed to the internet is a target for brute force attacks, injection attempts, connection flooding, and automated abuse. Defending against these threats typically requires bolting on external middleware, writing custom filtering logic, or deploying a separate reverse proxy — all of whic...
