Weekend Project, Built a Vanilla JavaScript Online Code Editor (2022)
Vanilla JS editor with regex loop prevention, but CodePen already owns this.
Webブラウザで動く、依存ゼロの漫画・コミックビューアです。右綴じ/左綴じ、見開き、ピンチズーム、スワイプ、しおり、PWA対応。MITライセンスでご利用いただけます。 / A standalone, zero-dependency manga & comic viewer for the web (RTL/LTR, spread, pinch-zoom, swipe, bookmarks, PWA-aware).
Drop-in reader that actually respects Japanese reading conventions: RTL page order, automatic two-page spreads in landscape, and touch-friendly features like pinch zoom with inertia and double-tap zoom. It’s deliberately tiny — ES module, no build step, localStorage resume — and adds practical niceties (insertable ad/pages, preview limits, status-bar cover) that make it useful for anyone shipping comics on the web, even if the idea itself isn’t groundbreaking.
