Package: drogonR 0.1.8

drogonR: High-Performance HTTP Server for R via 'Drogon'

Provides an 'R' interface to the 'Drogon' high-performance 'C++' 'HTTP' server framework (<https://github.com/drogonframework/drogon>). Offers a 'plumber'-style application programming interface for building 'REST' services from 'R' with substantially higher throughput, including streaming responses and full-duplex 'WebSocket' endpoints.

drogonR — Three Ways to Serve HTTP from R
Choosing a variant | Performance snapshot | A minimal example of each | Where to go next

Rate limiting
Quick start | How it works | Algorithms (type =) | Scope (scope =) | Prefix matching (routes =) | Per-IP limiting | Operational notes

Streaming responses (chunked HTTP, SSE)
How it works | dr_stream() — the base API | dr_stream_sse() — Server-Sent Events | Threading: keep each pump short | Cancellation contract | Errors inside next_chunk() | Middleware does not wrap individual chunks | Native (C / C++) streaming | Caveats

Variant 1 — C++ Shared Path (dr_*_cpp)
The handler ABI | A complete example | Threading rule (critical) | Memory ownership cheat-sheet | Where this fits

Variant 2 — drogonR Native API (dr_app / dr_get / …)
Building an app | The req object | Building responses | Middleware | Static files | Starting and stopping the server | When to reach for the other variants

Variant 3 — Plumber Drop-In (drogonR::pr_run)
The one-line swap | What the shim supports | What the shim rejects | A minimal end-to-end example | When to migrate to native
