@collie-lang/expo

Metro transformer utilities for compiling .collie files inside Expo / React Native projects.

Installation

pnpm add -D @collie-lang/expo

Metro already ships with metro-react-native-babel-transformer. The Collie transformer wraps it, so no extra configuration is required.

Usage

// metro.config.js
const { withCollieMetro } = require("@collie-lang/expo");

module.exports = withCollieMetro({});

This helper:

• Adds collie to the resolver extensions.
• Points Metro at the Collie-aware transformer so .collie files compile to React components on the fly.

If you prefer manual control, add the transformer path and resolver entries yourself:

const { createCollieMetroTransformer } = require("@collie-lang/expo");

module.exports = {
  transformer: {
    babelTransformerPath: require.resolve("@collie-lang/expo/metro-transformer")
  },
  resolver: {
    sourceExts: ["js", "jsx", "ts", "tsx", "json", "collie"]
  }
};
