Welcome

Funkcia is a TypeScript library that provides robust error handling and functional programming primitives, heavily inspired by Rust's error handling patterns and functional programming concepts.

It provides a comprehensive toolkit for writing more reliable code with better error handling and functional programming patterns, making it easier to write maintainable and type-safe applications.

Docs parity checklist

Before publishing docs updates:

• Verify public API names against source exports in /packages/funkcia/src.

• Ensure method headings match API casing exactly.

• Remove stale methods that no longer exist in source.

• Confirm SUMMARY.md links point to real files.

• Run a quick search for known removed APIs to avoid drift regressions.
