What does LocaleData do?
LocaleData is a translation management platform built specifically for Ruby on Rails applications. It helps developers and their teams manage the YAML files used for app localization. You can import your existing translation files, work on them in a collaborative web editor, and then export the updated YAML files back into your project. This process is designed to be simple and to prevent the syntax errors that can happen when editing YAML files manually.
The tool works by providing a dedicated Ruby gem and command-line interface for syncing translations between your Rails project and the LocaleData platform. Its editor supports various translation types, including text, plurals, and arrays. A key feature is its integration with the Google Translation API, which can automatically translate text into over 130 languages, saving time on manual copy-pasting. The platform also includes bulk editing tools and allows you to set different access roles for team members like admins, developers, and translators.
LocaleData is most useful for development teams building software that needs to be available in multiple languages. It removes the technical barrier of YAML file management, allowing non-developers to contribute directly to translations. Real-world use cases include a development team streamlining the process of launching their app in new regions, or a project manager coordinating with freelance translators without needing to touch the codebase.
