FBT is an internationalization framework for JavaScript designed to be not just powerful and flexible, but also simple and intuitive. It helps with the following:

• Organizing your source text for translation
• Composing grammatically correct translatable UI
• Eliminating verbose boilerplate for generating UI

Examples

See our demo here See our React Native demo here

Requirements

• Node.js
• Yarn
• Babel

Building the fbt library

git clone git@github.com:facebook/fbt.git
cd fbt
yarn install

NOTE: if you make changes to the fbt runtime that you'd like to test in the demo-app, be sure to run this command to rebuild the JS code:

yarn build-runtime

Using fbt

See how to use the source directly with Babel and Webpack in our demo-app.

How FBT works

FBT works by transforming your <fbt> and fbt(...) constructs via Babel plugins. These plugins serve to extract strings from source and lookup translated payloads generated at build-time. FBT creates tables of all possible variations for the given fbt phrase and accesses this at runtime.
