fluent-transpiler

fluent-transpiler is a build-time tool that compiles Fluent (.ftl) localization files into optimized, tree-shakable JavaScript ES modules. Current stable version is 0.4.1. It supports single and multiple locales, allows selective message inclusion/exclusion, and offers variable naming conventions (camelCase, PascalCase, etc.). Unlike runtime i18n libraries like @fluent/react or react-intl, fluent-transpiler produces zero-runtime code, ideal for modern bundlers with tree shaking. Requires Node >=24 and ships TypeScript definitions.
