i18n vs. i18next
What is i18n?
i18n (short for "internationalization") is the practice of designing and developing software so it can be easily adapted for different languages, regions, and cultures — without major code changes. This means:
- Separating UI strings, date formats, currencies, and other locale-specific elements from your code
- Using placeholders and resource files for translations
- Making your app ready for localization (l10n)
What is i18next?
i18next is a popular open-source JavaScript library that helps you implement i18n in your web or JavaScript-based applications. It provides:
- Easy JSON based translation management
- Pluralization and context support
- Language detection and fallback
- Integration with frameworks like React, Vue, Angular, and more
How do they relate?
- i18n is the goal (making your app adaptable for any language or region)
- i18next is a tool that helps you achieve that goal in JavaScript projects
Think of i18n as the process, and i18next as the toolkit that makes the process easier and more robust.
Why use i18next?
i18next saves you time and effort by providing all the features you need for internationalization out of the box. Instead of building your own translation and formatting logic, you can rely on a well-tested, community-supported solution.
