s-date
JSON →Tiny date/time formatter (~1KB minified) with a simple template-based API. Current stable version is 1.6.4, with no updates since 2020. It is in maintenance mode. It provides Moment.js-like formatting strings (e.g., {yyyy}, {mm}, {Month}) but at a fraction of the size. Unlike Luxon or date-fns, it focuses on minimal bundle size and straightforward formatting. It ships with TypeScript declarations, supports both CommonJS and ES module via conditional exports.
