Chronos HTTP server FFI

This folder contains a simple chronos-based http server serving requests on a given port.

The server runs on a separate thread and makes a callback into the host language for every request it responds to.

Notable features:

• The server runs in a separate thread created by Nim as part of the startNode function
• A Context object is passed to the host language and used in interactions with the node
• Callbacks are executed from the Nim thread into the host language
• The library initializes itself the first time a node is started
• For cross-thread communication, manual memory management is used
