Fluent Vue Internationalization Unplugin

unplugin-fluent-vue is a build tool plugin that integrates Fluent.js for internationalization (i18n) into Vue.js projects. It provides support for defining Fluent messages directly within Vue Single File Components (SFCs) using custom blocks, or by referencing external `.ftl` (Fluent Translation List) files. It currently stands at version 1.4.1 and sees regular maintenance releases, with the latest update in April 2026. This unplugin differentiates itself by offering a unified API for Vite, Webpack, and Rollup, leveraging the unplugin ecosystem. Key features include syntax checking for Fluent messages, optional in-build FTL parsing, and dedicated plugins for SFC-based or external file-based message definitions, making it a flexible choice for Vue i18n with Fluent.
