Libraries I maintain and patches I have upstreamed.

  • Library · TypeScript · ★ 18 timekeeper-countdown

    Lightweight, zero-dependency countdown engine and React useCountdown hook, implemented in pure TypeScript and published as a monorepo. The framework-agnostic core uses a guarded monotonic time provider, immutable snapshots, lossless time decomposition, formatting helpers, and fake-time utilities for deterministic tests. Both packages ship ESM and CommonJS bundles, with VitePress documentation and CI.

    npm: @timekeeper-countdown/core @0.3.2 · @timekeeper-countdown/react @0.3.2

  • Library · Erlang · ★ 6 erli18n

    Modern GNU gettext-compatible internationalization for Erlang/OTP 27+, implemented in pure Erlang and organized as a rebar3 umbrella with two separately published Hex packages. The erli18n runtime provides .po/.pot loading, copy-free persistent_term lookups, CLDR pluralization, the full gettext facade family, locale negotiation and fallback, telemetry, and optional Cowboy, Elli, and erlydtl integrations. The rebar3_erli18n 0.2.0 plugin extracts, merges, checks, reports, and compiles catalogs from Erlang abstract forms, including opt-in compile-time .po-to-BEAM generation.

    It is listed in erlang-punch/awesome-erlang , the community-curated catalog of notable Erlang libraries and resources.
