FAQPage Schema
How do I set up i18next with React and TypeScript for type-safe translations?

Set up i18next with React by initializing the framework with LanguageDetector and React integration, then use CustomTypeOptions in TypeScript to enable autocomplete and safer translation keys across your project.

What is the best way to manage multiple translation namespaces in react-i18next?

Manage multiple translation namespaces in react-i18next by configuring namespace resources during initialization and specifying the desired namespace in the useTranslation hook to load localized strings efficiently.

How do I handle plurals and interpolation in i18next?

Handle plurals and interpolation in i18next by passing dynamic values into translation keys. The API supports nested keys, pluralization rules, and variable interpolation to output context-aware localized text.

Does i18next v25 work with react-i18next v16 for runtime language switching?

Yes, i18next v25 works with react-i18next v16 for runtime language switching. You can use the i18n.changeLanguage API to dynamically update the active locale without reloading the application.

When should I use the Trans component instead of the useTranslation hook?

Use the Trans component instead of the useTranslation hook when you need to render complex localized strings that include embedded React components or HTML tags within the translation output.

Why do I need TypeScript CustomTypeOptions in my i18next configuration?

You need TypeScript CustomTypeOptions in i18next to enforce strict type safety on translation keys. This configuration provides autocomplete and compile-time checks to prevent missing or invalid translation references.
