babel-plugin-fbt

The main Babel transform plugin for Facebook's FBT (Facebook Translation) internationalization framework. Current stable version is 1.0.0, released with a regular cadence alongside the FBT ecosystem. It provides compile-time extraction and transformation of <fbt> elements and fbt() calls for localization. Key differentiators include React-integrated string interpolation with gender and number variations, and a hash-based string collection approach. Requires pairing with fbt-babel-plugin-runtime for runtime token resolution and @fbtjs/default-collection-transform for string collection outputs.
