Paraglide JS

Compiler-based i18n library. Compiles translation files (JSON/inlang) into tree-shakable JS functions. Each message becomes a function — only used messages are bundled.

Architecture

messages/          ← Translation source files (JSON)
  en.json
  de.json
project.inlang/
  settings.json    ← Inlang project config (locales, plugins, sourceLanguageTag)
src/paraglide/     ← Compiler output (generated, gitignored)
  messages.js      ← Compiled message functions
  runtime.js       ← getLocale(), setLocale(), locales, sourceLocale
  server.js        ← paraglideMiddleware() for SSR

Compiler runs via bundler plugin (Vite/Webpack/Rollup) or CLI. Output is always ./src/paraglide/.
