GitHubDev Utilities & Vibe-Coding Tooling · Type-safe TypeScript
Transformer that compiles TypeScript types into optimised runtime validators, serializers and random generators with no schema declaration.
Why it’s a gem
Validation straight from your existing types, orders of magnitude faster than schema libraries.
Functional building blocks for TypeScript: Option, Result, AsyncData and Future types with a fluent, non-academic API.
Exhaustive pattern matching for TypeScript with type narrowing, so unhandled union branches become compile errors instead of runtime bugs.
Result and ResultAsync types for TypeScript that force explicit error handling at call sites instead of thrown exceptions.
Implementation of type-prefixed, K-sortable UUIDv7 identifiers so IDs carry their entity type and sort chronologically.
Runtime string utilities whose return types are computed at the type level, so camelCase or split results stay literally typed.
Tiny runtime validator that parses and coerces environment variables against a schema and fails the process at boot with a readable report.
