• 📦 Ultra-Lightweight: Minimal overhead and tiny bundle size.
• 🔗 Dot Notation: Access nested translations easily (e.g., user.profile.name).
• 🧩 Interpolation: Dynamic variables with {{param}} syntax.
• 🛡️ Reliable CI: Tested against production environments with 100% automated checks.
• 🛠️ Visual Debugger: Inspect translation keys and params in development.

📦 Installation

# Using pnpm (recommended)
pnpm add @ariaskit/astro-i18n

# Using npm
npm install @ariaskit/astro-i18n

Quick Start

1. Create translation files in i18n/ (e.g., en.json, es.json).
2. Use in your Astro pages:

---
import { useI18n } from "@ariaskit/astro-i18n";

const { t } = useI18n({ ssg: { astro: Astro } });
---

<h1>{t("common.title")}</h1>
<p>{t("common.welcome", { name: "User" })}</p>

🛠️ Debug Mode (Development Only)

This library includes a powerful Visual Inspector to help you identify translation keys and required parameters directly in the browser.

Note

Zero Production Overhead: The debug tool only renders during development (NODE_ENV === 'development'). In production, it renders pure HTML without any extra tags or tooltips.

Usage

Import I18NDebug and wrap your translated elements:

---
import { useI18n } from "@ariaskit/astro-i18n";
import I18NDebug from "@ariaskit/astro-i18n/I18NDebug.astro";

const { t } = useI18n({ ssg: { astro: Astro } });
---

<I18NDebug key="user.profile.title" params={["name", "role"]}>
  <h2>{t("user.profile.title", { name: "John", role: "Admin" })}</h2>
</I18NDebug>

  <I18NDebug key="nav.dashboard">

  </I18NDebug>

Inspector Features

• 🔍 Key Identification: Hover over any highlighted element to see its JSON key.
• 🏷️ Params Documentation: View exactly which variables a translation expects.
• 🎨 Smart Highlight: Elements are marked with a subtle yellow background on hover.
• 🧵 Layout Friendly: Designed as an inline element by default to preserve your UI flow.
