Argus RPC

Custom Binary RPC Protocol Over Raw TCP

arrow_back Back to home open_in_new GitHub

Overview

Lightweight TypeScript-native RPC protocol with binary framing, request correlation, heartbeats, retries, connection pooling, structured errors, and benchmarking.

Platform proof

Argus explores how service communication works beneath HTTP frameworks by implementing a custom protocol layer over raw TCP. It handles binary frames, message IDs, PING/PONG heartbeats, timeouts, retry behaviour, connection pools, and failure-aware communication.

Technical note

Argus focuses on the mechanics beneath everyday service communication. Binary frames, message IDs, heartbeats, retries, and pooled TCP connections are kept explicit so the protocol can be inspected, tested, and benchmarked from first principles.
