fluent-compiler

fluent-compiler (v0.1.0, stable pre-release) is a JavaScript transpiler for Project Fluent's FTL format. It compiles FTL messages into ES6 modules that export FluentBundle-compatible objects, shifting compilation from runtime to build time. Unlike the core `fluent` package (which ships a ~10kB runtime compiler), `fluent-compiler` outputs pre-compiled code with a ~1.2kB runtime dependency, reducing browser bundle size. It supports locale identifiers, optional AST input from `fluent-syntax`, configurable runtime imports, and Unicode isolation marks. Suitable for Node.js >=8.9.0 and build pipelines (Webpack, Rollup). Note: The runtime API is based on a draft PR (#360) and may change.
