GitHubDev Utilities & Vibe-Coding Tooling · Type-safe TypeScript
Schema-driven environment variable loader that validates values, documents them in .env files and detects secret leakage in builds.
Why it’s a gem
Treats .env as a typed, documented interface and catches leaked secrets before deploy.
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.
Transformer that compiles TypeScript types into optimised runtime validators, serializers and random generators with no schema declaration.
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.
