RailsConf 2025 Internationalization on Rails: Unpacking the Rails I18n Toolkit by Chris Fung

Building an app that’s "just in English" might feel sufficient, but what if your next user prefers Spanish, German, or Chinese? Localization and internationalization are often an afterthought for many developers, if they are thought of at all. But it’s not only big, global companies that can benefit from them. They’re essential for startups and solo developers, too. In this talk, I’ll demystify internationalization and show you how Rails makes it easy to bake internationalization into your app from the start. You’ll learn how to use tools built into Rails and from gems in the wider ecosystem to easily support multilingual users, and make your app available to more people, wherever they are!
