icu-minify

ICU message format compiler that converts ICU strings into a compact JSON array representation at build time, with a runtime bundle of only 650 bytes (minified + compressed) and zero runtime dependencies. Version 4.11.0 is current, released under the next-intl monorepo with frequent updates (multiple releases per month). Key differentiators: extremely small runtime footprint, full ICU support (plural, select, selectordinal, date, time, number, tags), and TypeScript-first design. Unlike alternatives like icu-to-json or @lingui/message-utils, icu-minify offers first-class ESM support, no polyfills needed, and seamless integration with next-intl.
