React i18n Documentation

The complete integration guide for React localization. Learn how to use AI for localization, automate your workflow, and master step-by-step React localization setup.

Step-by-Step React Localization Setup

1. Prepare Your Code

Ensure your React components are clean. PolyLingo works best with functional components.

// Just write standard React code. No special markup needed.
<button>Submit Form</button>

2. How to Export Translation JSON

Use our dashboard to scan your project. The AI will identify strings and generate a JSON file.

// Generated en.json
{
  "form.submit": "Submit Form"
}

3. How to Integrate AI Translations in React Code

Replace hardcoded strings with the generated keys using your preferred library (i18next, react-intl).

import { useTranslation } from 'react-i18next';

export function MyComponent() {
  const { t } = useTranslation();
  return <button>{t('form.submit')}</button>;
}

Common i18n Errors and Fixes

Missing Context

Problem: Translating "Right" without knowing if it means "Correct" or "Direction".

Fix: PolyLingo's AI analyzes the component tree to determine context automatically, generating keys like direction.right or status.correct.

Broken Plurals

Problem: "1 items" or "0 items" looking grammatically incorrect.

Fix: Our tool automatically detects pluralizable strings and generates proper ICU message formats or i18next plural keys.

Best Workflow for Multilingual React Apps

Follow these guidelines to maintain a scalable and maintainable codebase.

Centralize Keys

Keep all your translation keys in a single source of truth or split by feature modules.

Automate Extraction

Never manually extract strings. Use PolyLingo to scan and update your JSON files on every commit.

Review Context

Always review the AI-generated context to ensure the tone matches your brand voice.
