i18n

Overview

This skill provides a complete workflow for managing translations using i18next-cli.

The project uses:

• i18next / react-i18next for translations
• i18next-cli for key extraction and linting
• Locale files in src/locales/{lang}/translation.json

Quick Workflow

Option 1: Automated Replacement (Recommended)

pnpm i18n:translate

This script:

• Parses lint output to find hardcoded string locations
• Maps strings to translation keys from primary locale
• Replaces them with t("key") calls
• Adds useTranslation import and hook if missing

Note: If strings have no translation keys, the script will skip them. Add keys first.

Option 2: Manual Replacement

For manual replacement:

1. Find the string in the component file
2. Replace hardcoded text with t("key")
3. Add import { useTranslation } from "react-i18next" if missing
4. Add const { t } = useTranslation() inside the component function

Example:

// Before
<p>Cargando...</p>

// After
import { useTranslation } from "react-i18next";

export function MyComponent() {
  const { t } = useTranslation();
  // ...
  <p>{t("common.loading")}</p>
}

Step-by-Step Process

1. Find Hardcoded Strings

pnpm i18n:lint

2. Add Translation Keys

pnpm i18n:add "category.key" "English value"

3. Run Automated Replacement

pnpm i18n:translate

4. Verify

pnpm typecheck
pnpm i18n:lint

Key Naming Conventions

• Structure: category.subcategory.key (e.g., common.loading)
• Categories: Use existing or create new (e.g., common, students)
• Group related keys under a category namespace

Common Errors

• Cannot find name 't' - Add const { t } = useTranslation() to component
• 'useTranslation' is declared but never used - You need to actually use t() in the component
