🚀 About

Arnelify® Server for C & C++ — a multi-language server with HTTP 3.0 and WebTransport support.

All supported protocols:

#	Protocol	Transport
1	TCP1	HTTP 1.1
2	TCP1	HTTP 2.0
3	TCP1	WebSocket
4	TCP2	HTTP 3.0
5	TCP2	WebTransport

📋 Minimal Requirements

Important: It's strongly recommended to use in a container that has been built from the gcc v15.2.0 image.

• CPU: Apple M1 / Intel Core i7 / AMD Ryzen 7
• OS: Debian 11 / MacOS 15 / Windows 10 with WSL2.
• RAM: 4 GB

📦 Installation

Run in terminal:

git clone git@github.com:arnelify/arnelify-server-cpp.git

🎉 TCP2 / WebTransport

📚 Configuration

Option	Description
BLOCK_SIZE_KB	The size of the allocated memory used for processing large packets.
CERT_PEM	Path to the TLS cert-file in PEM format.
COMPRESSION	If this option is enabled, the server will use BROTLI compression if the client application supports it. This setting increases CPU resource consumption. The server will not use compression if the data size exceeds the value of BLOCK_SIZE_KB.
HANDSHAKE_TIMEOUT	Maximum time in seconds to complete the TLS handshake.
KEY_PEM	Path to the TLS private key-file in PEM format.
MAX_MESSAGE_SIZE_MB	Maximum size of a single message the server will accept from a client.
PING_TIMEOUT	Maximum time the server will wait for a ping from the client.
PORT	Defines which port the server will listen on.
SEND_TIMEOUT	Maximum time for the client to receive a response from the server.
THREAD_LIMIT	Defines the maximum number of threads that will handle requests.

📚 Examples

⭐ Release Notes

Version 0.9.3 — a multi-language server with HTTP 3.0 and WebTransport support.

We are excited to introduce the Arnelify Server for NodeJS! Please note that this version is raw and still in active development.

Change log:

• Async Multi-Threading.
• Block processing in "on-the-fly" mode.
• BROTLI compression (still in development).
• FFI, PYO3 and NEON support.
• Significant refactoring and optimizations.

Please use this version with caution, as it may contain bugs and unfinished features. We are actively working on improving and expanding the server's capabilities, and we welcome your feedback and suggestions.
