# Paraglide JS Compiled Output > Auto-generated i18n message functions. Import `messages.js` to use translated strings. Compiled from: `/Users/kalekber/code/libnovel-v2/ui/project.inlang` ## What is this folder? This folder contains compiled [Paraglide JS](https://github.com/opral/paraglide-js) output. Paraglide JS compiles your translation messages into tree-shakeable JavaScript functions. ## At a glance Purpose: - This folder stores compiled i18n message functions. - Source translations live outside this folder in your inlang project. Safe to import: - `messages.js` — all message functions - `runtime.js` — locale utilities - `server.js` — server-side middleware Do not edit: - All files in this folder are auto-generated. - Changes will be overwritten on next compilation. ``` paraglide/ ├── messages.js # Message exports (import this) ├── messages/ # Individual message functions ├── runtime.js # Locale detection & configuration ├── registry.js # Formatting utilities (plural, number, datetime) ├── server.js # Server-side middleware └── .gitignore # Marks folder as generated ``` ## Usage ```js import * as m from "./paraglide/messages.js"; // Messages are functions that return localized strings m.hello_world(); // "Hello, World!" (in current locale) m.greeting({ name: "Sam" }); // "Hello, Sam!" // Override locale per-call m.hello_world({}, { locale: "de" }); // "Hallo, Welt!" m.greeting({ name: "Sam" }, { locale: "de" }); // "Hallo, Sam!" ``` ## Runtime API ```js import { getLocale, getTextDirection, setLocale, locales, baseLocale } from "./paraglide/runtime.js"; getLocale(); // Current locale, e.g., "en" getTextDirection(); // "ltr" | "rtl" for current locale setLocale("de"); // Set locale locales; // Available locales, e.g., ["en", "de", "fr"] baseLocale; // Default locale, e.g., "en" ``` ## Strategy The strategy determines how the current locale is detected and persisted: - **Cookie**: Stores locale preference in a cookie. - **URL**: Derives locale from URL patterns (e.g., `/en/about`, `en.example.com`). - **GlobalVariable**: Uses a global variable (client-side only). - **BaseLocale**: Always returns the base locale. Strategies can be combined. The order defines precedence: ```js await compile({ project: "./project.inlang", outdir: "./src/paraglide", strategy: ["url", "cookie", "baseLocale"], }); ``` See the [strategy documentation](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/strategy) for details. ## Markup (Rich Text) Messages can contain markup tags for bold, links, and other inline elements. Translators control where tags appear; developers control how they render. ### Message syntax ```json { "cta": "{#link to=|/docs|}Read the docs{/link}", "bold_text": "This is {#bold}important{/bold}" } ``` - `{#tagName}` opens a tag, `{/tagName}` closes it. - Options: `to=|/docs|` (accessed via `options.to`). - Attributes: `@track` (boolean, accessed via `attributes.track`). This is the default inlang message syntax. Paraglide's message format is plugin-based — you can use [ICU MessageFormat 1](https://inlang.com/m/p7c8m1d2/plugin-inlang-icu-messageformat-1), [i18next](https://inlang.com/m/3i8bor92/plugin-inlang-i18next), or other [plugins](https://inlang.com/c/plugins) instead. ### Rendering markup Calling `m.cta()` returns **plain text** (markup stripped). To render markup, use the framework adapter or the low-level `parts()` API: ```js const parts = m.cta.parts({}); // [ // { type: "markup-start", name: "link", options: { to: "/docs" }, attributes: {} }, // { type: "text", value: "Read the docs" }, // { type: "markup-end", name: "link" } // ] ``` Framework adapters provide a `` component that accepts markup renderers: - `@inlang/paraglide-js-react` - `@inlang/paraglide-js-vue` - `@inlang/paraglide-js-svelte` - `@inlang/paraglide-js-solid` ```jsx import { ParaglideMessage } from "@inlang/paraglide-js-react"; // or -vue, -svelte, -solid {children}, }} /> ``` See the [markup documentation](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/markup) for details. ## Key concepts - **Tree-shakeable**: Each message is a function, enabling [up to 70% smaller i18n bundle sizes](https://inlang.com/m/gerre34r/library-inlang-paraglideJs/benchmark) than traditional i18n libraries. - **Typesafe**: Full TypeScript/JSDoc support with autocomplete. - **Variants**: Messages can have variants for pluralization, gender, etc. - **Fallbacks**: Missing translations fall back to the base locale. ## Links - [Paraglide JS Documentation](https://inlang.com/m/gerre34r/library-inlang-paraglideJs) - [Source Repository](https://github.com/opral/paraglide-js)
