elemix
Custom Elements done right (Reactive Elements) — a compile-first library, one of the fastest on the planet 🌍. Its compiler is written in Rust, built for every CPU and architecture and shipped over npm — wasm included. In active development, closing a release of v0.9.0.
github → roadmap →elemix playground
In-browser playground for elemix 🛝 — a multi-file Monaco editor with TypeScript IntelliSense and SCSS, live bundling via esbuild-wasm, and an instant preview pane ⚡. Pre-compiler era, targeting the older v0.8.2 🕰️.
github → live preview →wikipulse
Live dashboard that consumes Wikimedia's recent-changes SSE stream. Built with elemix, a web components framework written by me.
github → live preview →nim
Disk-backed key/value cache for go. Atomic writes via tmpfile + rename, per-key file locks for concurrent access, symlink-based TTL expiration.
github →openapi-tsgen
CLI that generates typescript types from openapi schemas (yaml or json). Written in go, ships as a single cross-platform binary.
