Travis Stanley discusses a method for implementing localization with Gatsby and Sanity.io, a solution that is both efficient and user-friendly for content teams and developers. He describes his experience with two website projects that required localization, noting the challenges and improvements he encountered. The initial project involved separate builds for each language, while the second project adopted a single-build approach that allowed pages to be generated for every language using a unified URL structure. Sanity.io's flexible schemas and Gatsby's capabilities were leveraged to streamline the localization process, allowing for easy addition of translations and automatic generation of language-specific pages. Stanley emphasizes the benefits of using Sanity.io as a content backend and encourages developers to explore this combination for fast and scalable web development.
