What problem does it solve?
Effect Schema v4 API changes make it easy to accidentally keep v3 patterns (renamed functions, changed signatures, and removed modules), leading to broken codecs and confusing runtime/typing errors during migrations.
Core Features & Use Cases
- Authoritative v4 migration guidance: Provides a migration reference for key v4 Schema API renames and behavioral changes from v3.
- Concrete change tables & patterns: Covers function/constructor renames, variadic-to-array signature shifts, filter-to-check migration, and transform API redesigns.
- Migration cheat-sheets for common pitfalls: Highlights removed APIs (like Schema.Data), optional-key semantics, and recommended replacements.
Quick Start
Use the effect-schema-v4 skill to look up the correct v4 Schema API name and signature before writing or refactoring your migration from v3 Schema code.
