Lit is a library from Google that enables the construction of fast, reactive web applications by leveraging the browser's own component model and event handling rather than imposing it from the outside as React, Angular, and other application development platforms do. Lit has an effective localization library that supports both static and dynamic modes, with most developers preferring the dynamic mode for its ability to change languages without reloading the page. The basics of Lit's localization workflow involve building a wrapper function around text strings, specifying a `lit-localize.json` file with target locales, extracting locale files using `lit-localize extract`, sending locale files to translators, and running `lit-localize build` to generate translation files. To update the language dynamically, a custom context manager is created to preserve and update the locale request context, which includes functions to get and set the locale, as well as an event listener to handle changes in the locale string. The context manager provides the tools needed to apply localization to all components via the `@localized()` decorator and display the list of locales, enabling Lit applications to be made available to customers around the world in their own language.
