Gleam Erlang Interop FAQs

Question 1

Does this skill help with Elixir interoperability?

Accepted Answer

Since Elixir also runs on the BEAM, the same interop principles for calling Erlang functions apply to calling Elixir modules from Gleam.

Question 2

What are NIFs and does this skill support them?

Accepted Answer

NIFs (Native Implemented Functions) allow you to call C or Rust code from Gleam via the Erlang runtime. This skill includes patterns for declaring and loading these native libraries.

Question 3

Can I use any Erlang library within my Gleam project?

Accepted Answer

Yes, by using @external declarations, you can call any Erlang module and function. This skill provides the patterns needed to map Erlang's dynamic signatures to Gleam's static types.

Question 4

Is it possible to use Erlang's ETS for caching in Gleam?

Accepted Answer

Absolutely. This skill covers how to interface with Erlang Term Storage (ETS) to create high-performance, in-memory data stores directly from Gleam.

Question 5

How does Gleam handle Erlang's dynamic type system safely?

Accepted Answer

Gleam uses the 'dynamic' module and decoders to validate Erlang terms at runtime, ensuring they match your expected Gleam types before they enter your application logic.
