Connect Locale Middleware

connect-locale is a configurable Express/Connect middleware designed specifically for detecting and storing user locale preferences within web applications. It is not a comprehensive i18n solution for managing resource files, but rather focuses on establishing a flexible strategy for locale identification and persistence. The library allows developers to define a sequence of strategies (e.g., path, cookie, accept-language header) to determine the user's preferred locale and then store it in various locations (e.g., cookie, session, request object, `res.locals`) for subsequent use in other middleware or templating engines. The current stable version is 1.3.3. Given its last update several years ago, it is in maintenance mode, providing a stable, albeit not actively developed, solution for locale detection. Its key differentiators are its highly configurable detection and storage mechanisms, allowing for custom i18n strategies.
