What is the Gleam programming language?

Gleam is a statically-typed functional language that compiles to Erlang and JavaScript, designed to bring modern type safety to the high-concurrency BEAM ecosystem.

Can this skill help prevent runtime errors?

Yes, by utilizing Gleam's exhaustive checking and eliminating null values through Result and Option types, this skill helps you build applications that are virtually free of common runtime crashes.

How does this skill help with Gleam development?

It provides Claude with specialized patterns for implementing custom types, generics, and exhaustive pattern matching, ensuring code follows Gleam's idiomatic best practices.

Does it support Gleam's interoperability features?

The skill focuses on the core type system, which is essential for creating safe wrappers around Erlang or JavaScript libraries.

Developer Tools

Implements robust, type-safe Erlang VM applications using Gleam's advanced functional type system and algebraic data types.

This skill empowers Claude to leverage the full power of the Gleam programming language's static type system to build resilient applications on the BEAM and JavaScript runtimes. It provides expert guidance on defining algebraic data types (ADTs), implementing exhaustive pattern matching, and utilizing generic types for reusable code. By following these patterns, developers can eliminate entire classes of runtime errors, handle side effects safely via Result and Option types, and create domain models that make invalid states unrepresentable through the use of opaque and phantom types.

Key Features

01Utilize generic types and parametric polymorphism for reusable component design

02Define complex domain models using Algebraic Data Types (ADTs) and custom records

03Leverage opaque types and phantom types to enforce strict API constraints

04Apply functional error handling patterns using Result and Option types
