Yapee supports auto-detection (browser language) and manual override (Options → Language selector).
Translations are stored in _locales/:
_locales/
en/messages.json # English (default)
fr/messages.json # French
To add a new language:
- Create
_locales/<code>/messages.json(e.g.,defor German,esfor Spanish) - Copy
_locales/en/messages.jsonas a template - Translate all
"message"values — keep all keys and"placeholders"unchanged - Add the new locale as an
<option>inoptions.html(language selector) - Test the translation in your browser
- Submit a pull request
HTML elements use data-i18n attributes for automatic translation. JavaScript code uses the msg() helper from js/i18n.js. When a manual locale is set, messages are loaded from the JSON file at runtime; otherwise chrome.i18n.getMessage() handles browser auto-detection.
- Manifest V3 with service worker background script
- Content script relay for Tampermonkey communication
- AES-GCM 256-bit encryption for stored credentials (WebCrypto API)
- Bootstrap 5 UI with dynamic dark/light theme switching
- Event streaming via PyLoad's real-time event API
- Modular i18n system with runtime locale override (
initLocale/setLocale)
