Peter van der Zee and facebook-github-bot Fix adding jsx expression children in fbt
The fbt plugin supports `<fbt>...</fbt>` syntax and will transform these all the same. However, when the remainder of the jsx is not transformed it leaves it in a bad state;

FBT is an internationalization framework for JavaScript designed to be both 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


See our demo here


Building fbt

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

Installing fbt

We will make the transform and runtime installable as an npm package soon. Until then, See how to use the source directly with Babel and Webpack in our demo-app:

cd demo-app # from fbt repo
yarn install
yarn manifest
yarn collect-fbts
yarn translate-fbts
yarn start

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 translate payloads generated at build-time. FBT creates tables of all possible variations for the given fbt phrase and accesses this at runtime.
