Building native Node.js addons in Reason
summary
Shows how to build a real Node.js native addon from Reason/OCaml: initialize with npm, run camlnode + dune build to produce a .node shared object, and register via Node’s N-API rather than raw V8 or NAN. Demonstrates converting values (value_to_float/value_to_string), composing signature codecs to validate args, creating functions exported to JS, and attaching OCaml data with extensible externals. Live demo mostly works but notes added N-API safety tradeoffs: persistent refs hurt perf and leaks are possible.
