fumadocs-i18n

What problem does it solve?

Automates the complete setup of multi-language support for a Fumadocs project, enabling clean, scalable international documentation.

Core Features & Use Cases

• Configure directory-based i18n routing with a default language and per-language content folders.
• Add a language switcher to the UI and ensure language-specific sidebars.
• Restructure the app layout to support [lang] routing and per-language docs, with content organized under content/docs/{lang}/.
• Use-case: You are building a multilingual docs site and want consistent URLs like /en/docs and /zh/docs with isolated content trees.

Quick Start

Provide a new project with a fully localized docs site by applying this Skill:

• Create lib/i18n.ts with parser: 'dir' and supported languages.
• Implement middleware for locale routing.
• Move app routes under [lang] and adjust layouts to use source.pageTree[lang].
• Organize content under content/docs/{lang}/ and add per-language content.
• Run build and test language switching and per-language routes.
