Guidance for writing C++ back-end services with Drogon, a web framework for building HTTP servers. It focuses on asynchronous code and common problems with callbacks and event loops.

Use it when building Drogon-based back ends, HTTP servers, or database-backed services in C++. It supports work involving Drogon’s asynchronous programming patterns.

It helps avoid mistakes that can make asynchronous server code behave incorrectly or become difficult to maintain.

Security

Grade A, and why

drogon scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
