Gleam Erlang Interop
Gleam Erlang Interop
Introduction
Gleam compiles to Erlang, enabling seamless interoperability with the vast Erlang ecosystem. This interop allows Gleam developers to leverage battle-tested Erlang libraries while writing type-safe Gleam code, combining modern language features with decades of production-proven libraries.
The interop mechanism uses external functions to call Erlang code, with Gleam's type system providing safety at the boundary. Gleam can call any Erlang function, use Erlang processes, and integrate with OTP behaviors while maintaining type safety.
This skill covers external function declarations, calling Erlang modules, working with Erlang types, using Erlang standard library, NIFs and ports, and patterns for safe type boundaries when integrating with Erlang code.
