End-to-end Purescript with Erlang/OTP
summary
Claim: PureScript compiles to Erlang/BEAM so the same typed code runs front and back, producing .beam files that load into rebar3 builds and support hot code reload. Demoed typed wrappers over supervisors and gen_server-style services, a PureScript web handler stack compiled against cowboy and JSX/simple-json, and an FFI strategy for legacy modules with opaque types and side-effect functions. Works at scale on a codebase with ~1,000,000 lines of Erlang and is already shipping to clients.
