DIY In-App Locale Editor with slang
Not sure if those AI-generated translations are any good? Don't want to spend a fortune on localization tools? Or maybe you just love over-engineering things?
In this lightning talk, you'll learn how to build an in-app locale editor using the slang library. Imagine Widgetbook and Localizely had a baby - and it lived inside your app. Let your users fix translations for you!
We'll cover:
- What slang offers and how to set it up
- Organizing your locale files for editing
- Building a simple string editor UI
- Integrating it cleanly into your app's architecture
- Previewing changes live - even in production
- Tracking which strings are actually used in your widget tree
Live demo included!
