Show HN: BinaryRPC – Lightweight WebSocket-based RPC framework in modern C++

10 months ago

BinaryRPC is a high-throughput RPC framework built on uWebSockets, designed for latency-sensitive applications like multiplayer games and financial tick streams.
The framework supports configurable reliability levels (None, AtLeastOnce, ExactlyOnce) with retries, ACKs, and two-phase commit mechanisms.
BinaryRPC features pluggable layers for protocols, transports, middleware, and plugins, allowing for extensive customization.
Stateful sessions with automatic expiry and indexed fields enable reconnect-friendly operations.
Middleware chains support functionalities like JWT auth and rate-limiting, similar to Express.js.
The framework is header-only, making it lightweight and easy to integrate into projects.
Dependencies include CMake (3.16+), a C++20 compiler, vcpkg, and Git. Optional dependencies like JWT and JSON support can be added as needed.
Installation involves cloning the repository, building with CMake, and linking the library in your project.
BinaryRPC provides a modular architecture with replaceable components for QoS, serialization, transport, middleware, and plugins.
The framework includes utilities for logging, error handling, and session management, with detailed examples provided for common use cases.
